Taiwan Semiconductor Corporation GPAS1002

Overview

GPAS1002 from Taiwan Semiconductor is a 10A, 100V standard surface-mount rectifier diode in TO-263AB (D2PAK) package, featuring glass-passivated junction, low forward voltage (≤1.10 V at 10 A), and high surge capability (150 A, 8.3 ms). It is used in DC-DC converters and switching-mode inverters requiring efficient unidirectional conduction.

For engineers reviewing the GPAS1002 datasheet, GPAS1002 pinout, GPAS1002 application, or GPAS1002 equivalent, key selection factors include its 100 V repetitive peak reverse voltage, 4 °C/W junction-to-case thermal resistance, 5 µA max reverse leakage at 25 °C, and RoHS/halogen-free compliance for industrial power conversion designs.

Technical Context

The GPAS1002 is a single-die, standard recovery silicon rectifier optimized for medium-voltage, high-current switching power supplies. Its glass-passivated junction ensures stable performance under thermal cycling and humidity stress, while the TO-263AB package enables high-power dissipation with surface-mount assembly compatibility.

It operates across –55 °C to +150 °C junction temperature range and delivers 10 A average forward current with ≤1.10 V forward drop at rated load and 25 °C. Reverse leakage remains ≤5 µA at 25 °C and ≤100 µA at 125 °C under rated reverse voltage.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for GPAS1002?

The GPAS1002 has a maximum repetitive peak reverse voltage (V_RRM) of 100 V, as specified in the Absolute Maximum Ratings table. This value defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions. Exceeding this rating risks irreversible junction failure. The GPAS1002 is part of a family spanning 50 V to 1000 V, and its marking code 'GPAS1002' explicitly identifies the 100 V variant.

Is GPAS1002 suitable for reflow soldering without pre-baking?

Yes, GPAS1002 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to standard lead-free reflow profiles without prior baking. Its TO-263AB package and halogen-free molding compound are qualified for typical SMT assembly processes. This eliminates moisture-related popcorning risk and simplifies manufacturing logistics. Always verify the date code and storage conditions before use, as GPAS1002's qualification assumes proper dry-pack handling per J-STD-033.

What is the forward voltage (V_F) of GPAS1002 at rated current?

The GPAS1002 exhibits a maximum forward voltage (V_F) of 1.10 V at 10 A forward current and 25 °C junction temperature, measured under pulsed conditions (PW = 0.3 ms). At higher temperatures or continuous DC, V_F decreases slightly due to negative temperature coefficient. This low V_F directly reduces conduction losses in power stages where GPAS1002 is deployed-such as secondary-side rectification in DC–DC converters.

Does GPAS1002 have a thermally enhanced package?

Yes, GPAS1002 uses the TO-263AB (D2PAK) package with an exposed metal tab that serves as both the cathode terminal and primary thermal path. Its junction-to-case thermal resistance (R_θJC) is 4 °C/W, enabling efficient heat transfer to a PCB copper pour or external heatsink. This thermal performance makes GPAS1002 suitable for high-power-density designs where thermal management is critical-especially in industrial power supplies where GPAS1002 operates near its 10 A rating.

What are the key compliance certifications for GPAS1002?

GPAS1002 is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and its matte tin-plated leads satisfy J-STD-002 solderability requirements. It also passes JESD 201 Class 1A whisker testing. These certifications ensure GPAS1002 meets global environmental, safety, and reliability standards for industrial electronics-supporting compliance documentation for products where GPAS1002 is used in final assemblies.
