Debt Instruments [Abstract]
Credit Facilities	Credit Facilities On March 20, 2012, Semtech Corporation entered into a credit agreement with certain lenders (the “Prior Lenders”) and Jefferies Finance LLC, as administrative and collateral agent (the “Prior Credit Agreement”). Pursuant to the Prior Credit Agreement, the Prior Lenders provided the Company with senior secured first lien credit facilities in an aggregate principal amount of $350.0 million (the “Prior Credit Facilities”), consisting of term A loans in an aggregate principal amount of $100.0 million (the “Term A Loans”) and term B loans in an aggregate principal amount of $250.0 million (the “Term B Loans”). The initial carrying amounts totaled $99.5 million (net of original issue discount of $0.5 million) for the Term A Loans and $247.5 million (net of original issue discount of $2.5 million) for the Term B Loans. On May 2, 2013 (the “Closing Date”), Semtech Corporation, with each of its domestic subsidiaries as guarantors (the “Guarantors”), entered into a new Credit Agreement (the “New Credit Agreement”) with the lenders referred to therein (the “Lenders”) and HSBC Bank USA, National Association, as administrative agent and as swing line lender and letter of credit issuer. In accordance with the New Credit Agreement, the Lenders provided Semtech Corporation with senior secured first lien credit facilities in an aggregate principal amount of $400.0 million (the “New Facilities”) for a five year term, consisting of term loans in an aggregate principal amount of $150.0 million (the “Term Loans”) and revolving line of credit commitments in an aggregate principal amount of $250.0 million (the “Revolving Commitments”). The Revolving Commitments can be used as follows: up to $40.0 million for letters of credit, up to $25.0 million for swing line loans (as defined below), and up to $40.0 million for revolving loans and letters of credit in certain currencies other than U.S. Dollars (“Alternative Currencies”). Swing line loans are Base Rate (as defined below) loans made in immediately available funds denominated in dollars by a swing line lender in its sole and absolute discretion. As of July 26, 2015, there were no amounts outstanding under the letters of credit, swing line loans, and Alternative Currencies. At the Closing Date, $326.6 million of borrowings were outstanding under the New Facilities consisting of $149.3 million of Term Loans and $177.3 million of Revolving Commitments, net of $1.4 million of debt discounts resulting from amounts paid to the Lenders. As a result of debt refinancing and changes in some of the Lenders, $0.8 million of debt discounts were expensed in the second quarter of fiscal year 2014 and $0.6 million was capitalized as of May 2, 2013 and is being amortized using the effective interest method over the five year term of the New Credit Agreement. The expense is included in “Interest expense, net” in the condensed consolidated statements of operations. The proceeds from the New Facilities were used to repay in full the outstanding obligations of $327.5 million under the Prior Credit Facilities, which were terminated. The portion of the transaction associated with Prior Lenders was accounted for as a debt modification. Deferred financing costs incurred in the second quarter of fiscal year 2014, in connection with the New Facilities, were approximately $2.2 million, of which $1.0 million was expensed, inclusive of certain legal costs directly related to the refinancing. Of this amount $1.2 million was capitalized and is being amortized using the effective interest method over the five year term of the New Facilities. The expense is included in “Interest expense, net” in the condensed consolidated statements of operations for the six months ended July 26, 2015. As a result of the debt refinancing, the Company recorded a $7.1 million loss on debt modification of unamortized deferred financing costs and original issue discount associated with the Prior Credit Facilities in the fiscal year ended January 26, 2014. The remaining $1.7 million of unamortized deferred financing costs and original issue discount associated with the Prior Credit Facilities is being amortized over the five year terms of the New Facilities. The expense is included in “Interest expense, net” within the condensed consolidated statements of operations for the six months ended July 26, 2015. The New Credit Agreement provides that, subject to certain conditions, Semtech may request, at any time and from time to time, the establishment of one or more additional term loan facilities and/or increases to the Revolving Commitments in an aggregate principal amount not to exceed $100.0 million, the proceeds of which may be used for working capital and general corporate purposes; however the Lenders are not required to provide such increase upon our request. Interest on loans made under the New Credit Agreement in U.S. Dollars accrues, at Semtech’s option, at a rate per annum equal to (1) the Base Rate plus a margin ranging from 0.25% to 1.25% depending upon Semtech’s consolidated leverage ratio or (2) London Interbank Offered Rate (“LIBOR”) (determined with respect to deposits in U.S. Dollars) for an interest period to be selected by Semtech plus a margin ranging from 1.25% to 2.25% depending upon Semtech’s consolidated leverage ratio. The “Base Rate” is equal to a fluctuating rate equal to the highest of (a) the prime rate (as published by The Wall Street Journal), (b) ½ of 1% above the federal funds effective rate or (c) one-month LIBOR (determined with respect to deposits in U.S. Dollars) plus 1%. Alternative Currencies, other than Canadian Dollars, accrues at a rate per annum equal to LIBOR (determined with respect to deposits in the applicable Alternative Currency) for an interest period to be selected by Semtech plus a margin ranging from 1.25% to 2.25% depending upon Semtech’s consolidated leverage ratio. Interest on loans in Canadian Dollars accrues at a rate per annum equal to the CDOR Rate (as defined below) for an interest period to be selected by Semtech plus a margin ranging from 1.25% to 2.25% depending upon Semtech’s consolidated leverage ratio. The “CDOR Rate” for any interest period is the rate equal to the sum of: (a) the rate determined by the administrative agent with reference to the arithmetic average of the discount rate quotations of all institutions listed for CAD Dollar-denominated bankers’ acceptances displayed and identified on the “Reuters Screen CDOR Page” and (b) 0.10% per annum. CDOR Commitment fees on the unused portion of the Revolving Commitments accrue at a rate per annum ranging from 0.20% to 0.45% depending upon Semtech’s consolidated leverage ratio. Interest is paid monthly for a Base Rate loan and swing line loan and quarterly for a Euro dollar rate loan. Interest is payable on the revolving line of credit maturity date in the case of Revolving Commitments and the additional term maturity date in the case of additional Term Loans, respectively. As of July 26, 2015, the interest rates payable on both the Term Loans and the Revolving Commitments was 1.93%. As of July 26, 2015, there was $86.5 million outstanding under the Term Loans.

On July 14, 2014, the Company made a voluntary payment of $25.0 million against the Revolving Commitments. On March 4, 2015 the Company borrowed $35.0 million under the Revolving Commitments in connection with the acquisition of Triune (see Note 2).
