Item 7.01. Regulation FD Disclosure.

On June 4, 2010, Diodes Incorporated (the “Company”) issued a press release, announcing its expansion into a new semiconductor category with its first standard logic product family. A copy of the press release is attached as Exhibit 99.1 to this Report.

On June 8, 2010, the Company issued a press release to update its guidance for the second quarter of 2010. A copy of the press release is attached as Exhibit 99.2 to this Report.

On June 9, 2010, Dr. Keh-Shew Lu, the Company’s President and Chief Executive Officer, and Carl Wertz, the Company’s Vice President of Finance and Investor Relations, held a presentation at the UBS Global Technology and Services Conference. A copy of the presentation slides is attached as Exhibit 99.3 to this Report.

The information in this Item 7.01, including Exhibit 99.1, Exhibit 99.2 and Exhibit 99.3, will not be treated as filed for the purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section. This information will not be incorporated by reference into a filing under the Securities Act of 1933, or into another filing under the Exchange Act, unless that filing expressly refers to specific information in this Report. The furnishing of the information in this Item 7.01 is not intended to, and does not, constitute a representation that such furnishing is required by Regulation FD or that the information in this Item 7.01 is material information that is not otherwise publicly available.

In the presentation slides, attached as Exhibit 99.3, the Company utilized financial measures and terms not calculated in accordance with accounting principles generally accepted in the United States (“GAAP”) in order to provide stockholders with an alternative method for assessing its operating results in a manner that enables stockholders to more thoroughly evaluate its current performance as compared to past performance. The Company also believes these non-GAAP measures provide stockholders with a more informed baseline for modeling its future financial performance. The Company’s management uses these non-GAAP measures for the same purpose. The Company believes that its stockholders should have access to the same set of tools that it uses in analyzing its results. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. See Exhibit 99.1 to the Company’s Form 8-K, filed on May 11, 2010, for definitions of the non-GAAP financial measures, together with an explanation of why management uses these measures and why management believes that these non-GAAP financial measures are useful to stockholders. In addition, in Exhibit 99.1 to the Company’s Form 8-K, filed on May 11, 2010, it has provided tables to reconcile the non-GAAP financial measures utilized to GAAP financial measures.

Diodes Incorporated Announces Logic Products that Provide Upgrade for Industry Standard Parts

Diodes Incorporated expands into a new semiconductor category with its first standard logic product family

Dallas, Texas —June 4, 2010 —— Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, today has released its very first family of single-gate logic products. Built on an advanced 5V CMOS process and offering performance enhancements over existing alternatives, the 74LVC1Gxx series provides users with the eight most popular standard logic functions in SOT25 and SOT353 package options, and the 74LVCE1GXX series offers enhanced performance versions of these same functions.

Dr. Keh-Shew Lu, President and Chief Executive Officer of Diodes Incorporated said, “I’m pleased to announce Diodes’ entry into the standard logic market. The logic market represents a natural fit for Diodes’ strategic focus on high-volume standard products, and expands our serviceable available market by over 15% to an approximate $20 billion annual SAM. Furthermore, there are strong packaging synergies with our existing Analog and Discrete product lines. Many current logic suppliers are dependent on packaging subcontractors, and customers are seeing extended industry leadtimes on these products. Diodes has its own world-class cost-effective, high-volume assembly facility that’s well suited to the manufacture of low pin-count SOT25 and SOT353 packages. We’re pleased to be able to leverage this capability to provide users with an alternative source of quality, high-performance logic products.”

Suitable for use in a variety of communication, computing, consumer and networking equipment, the initial Logic product offering covers AND, NAND, OR, NOR, XOR, inversion and buffering functions. The single-gate products are cost effective replacements for industry standard parts in point-of-application general purpose logic, level shifting and signal isolation applications.

At 1.65V to 5.5V, the operating voltage range of the 74LVC1Gxx series is wide, enabling it to support both portable battery operated and traditional 5V applications. To address higher performance application requirements, the 74LVCE1Gxx extended specification products operate down to 1.4V, and provide a 30% enhancement in switching speeds at 1.8V as compared to the standard LVC family. Both families have 5.5V tolerant inputs, enabling the creation of voltage translation solutions.

In many applications, the logic products will draw less than 1µA of supply current, ensuring low power consumption. Their I_OFF output circuitry means that the output is disabled when the device is powered down, preventing damaging backflow current from entering the device or unnecessarily loading shared signal lines. Further information is available on the Company’s website at www.diodes.com/logic.

Diodes Incorporated Increases Second Quarter 2010 Guidance

Dallas, Texas — June 8, 2010 — Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today increased its revenue and gross margin guidance for the second quarter of 2010.

The Company is increasing its revenue guidance for the second quarter of 2010 due to increasing demand for the Company’s products in its worldwide markets. Revenue is expected to range between $147 million and $151 million, an increase of 7.5 to 10.5 percent sequentially, compared to its previous guidance of $143 million to $148 million or an increase of 4 to 8 percent sequentially. The Company is also raising its second quarter 2010 gross margin guidance due to gross profit growing faster than the revenue increase. Gross margin is expected to range between 35.0 to 36.0 percent versus its prior guidance of gross profit growing at the same rate as revenue, or gross margin of 34.9 percent.
