Taiwan Semiconductor Corporation GPAS1005

Overview

GPAS1005 from Taiwan Semiconductor is a standard surface-mount silicon rectifier diode configured as a single die in TO-263AB (D2PAK) package, rated for 10 A average forward current, 600 V repetitive peak reverse voltage (V_RRM), and 150 A non-repetitive surge current (I_FSM). It delivers low forward voltage drop (≤1.10 V at 10 A, 25°C) and ultra-low reverse leakage (≤5 µA at 25°C), making it suitable for high-efficiency DC/DC converters in industrial power supplies.

For engineers reviewing the GPAS1005 datasheet, GPAS1005 pinout, GPAS1005 application, or GPAS1005 equivalent, key selection criteria include verified V_RRM = 600 V, thermal resistance R_θJC = 4 °C/W, moisture sensitivity level 1 (J-STD-020), halogen-free compliance (IEC 61249-2-21), and TO-263AB mechanical compatibility with high-current PCB layouts.

Technical Context

This device operates as a unidirectional power rectifier with glass-passivated junction for enhanced reliability under thermal cycling and humidity stress. Its 600 V V_RRM rating supports mid-voltage switching-mode power supplies, while the 4 °C/W junction-to-case thermal resistance enables effective heat transfer to external heatsinks via the exposed drain tab.

The GPAS1005 exhibits low capacitance (50 pF at 1 MHz, 4 V reverse bias) and stable reverse leakage up to 100 µA at 125°C, supporting high-frequency operation in flyback and forward converter topologies without compromising EMI performance or efficiency.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for GPAS1005?

The GPAS1005 has a specified V_RRM of 600 V, confirmed in the Absolute Maximum Ratings table across all official documentation versions (D2211). This rating defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions and is validated per JEDEC test methods. The GPAS1005 must not be operated above this value in any design.

Does GPAS1005 have a defined moisture sensitivity level (MSL)?

Yes, GPAS1005 is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and requires no baking prior to reflow soldering. This is explicitly stated in the FEATURES section and verified in the Mechanical Data table. The MSL Level 1 classification applies directly to the GPAS1005 in its TO-263AB (D2PAK) packaging.

What is the forward voltage (V_F) of GPAS1005 at rated current?

The GPAS1005 exhibits a maximum forward voltage of 1.10 V at 10 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table under "Forward voltage(1)". This value is measured using a 0.3 ms pulse test and represents the worst-case conduction loss under nominal operating conditions. The GPAS1005 maintains this V_F performance across its full temperature range.

Is GPAS1005 halogen-free and RoHS compliant?

Yes, GPAS1005 meets both requirements: it is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section and confirmed in the Mechanical Data table. These compliance statements apply specifically to the GPAS1005 variant and are part of Taiwan Semiconductor's official product declaration. No additional qualification testing is needed to assert GPAS1005 compliance.

What is the thermal resistance from junction to case (R_θJC) for GPAS1005?

The GPAS1005 has a typical junction-to-case thermal resistance (R_θJC) of 4 °C/W, as published in the Thermal Performance table. This value is measured with the device mounted on a standard copper pad per JEDEC 51-14 guidelines and reflects the thermal path from the silicon die to the exposed cathode tab. Effective heatsinking of the GPAS1005 tab is essential to maintain TJ ≤ 150°C.
