Taiwan Semiconductor Corporation GPA805HC0G

Overview

GPA805HC0G from Taiwan Semiconductor is an AEC-Q101-qualified, single-die standard rectifier in TO-220AC package with 600 V repetitive peak reverse voltage (V_RRM), 8 A average forward current (I_F), and 1.1 V max forward voltage at 8 A and 25°C - used in automotive-grade DC-DC converters and switching inverters.

For engineers reviewing the GPA805HC0G datasheet, GPA805HC0G pinout, GPA805HC0G application, or GPA805HC0G equivalent, key selection criteria include its 600 V V_RRM, 150 A non-repetitive surge rating, glass-passivated junction, RoHS- and halogen-free compliance, and TO-220AC thermal performance (R_θJC = 2.5°C/W).

Technical Context

The GPA805HC0G is a single-die, through-hole standard rectifier optimized for high-reliability power conversion. Its glass-passivated junction ensures stable reverse leakage (<5 µA at 25°C, <100 µA at 125°C) and robust surge handling (150 A I_FSM, 8.3 ms half-sine).

Thermally, it delivers R_θJC = 2.5°C/W to support sustained 8 A conduction at case temperatures up to 125°C. The device operates across –55°C to +150°C junction range and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.

FAQ

What is the maximum junction temperature rating for GPA805HC0G?

The GPA805HC0G has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This rating is validated per AEC-Q101 stress testing and supports operation in under-hood automotive environments. Thermal design must maintain T_J ≤ 150°C using the specified R_θJC = 2.5°C/W and appropriate heatsinking. The GPA805HC0G datasheet confirms this limit applies across all operating conditions.

Is GPA805HC0G pin-compatible with other devices in the GPA801–GPA807 series?

Yes, all GPA801–GPA807 devices share identical TO-220AC package dimensions, pinout (anode, cathode, cathode tab), and mechanical footprint. The GPA805HC0G uses the same lead frame, terminal geometry, and mounting hole pattern as GPA801HC0G through GPA807HC0G - enabling drop-in voltage-scaling substitutions without PCB revision.

Does GPA805HC0G have a cathode-connected tab?

Yes, the metal tab on the GPA805HC0G is electrically connected to the cathode. This is confirmed in the mechanical drawings and marking diagram in the official GPA801–GPA807 datasheet. When mounted to a heatsink, electrical isolation is required unless the system design intentionally references the cathode to chassis ground.

What is the reverse leakage current specification for GPA805HC0G at 125°C?

At 125°C junction temperature and rated reverse voltage (600 V), the GPA805HC0G exhibits a maximum reverse leakage current (I_R) of 100 µA, per the Electrical Specifications table. This value is measured under pulse conditions (PW = 30 ms) and reflects stable performance under elevated thermal stress - critical for high-temperature industrial and automotive applications.

How does the "H" suffix in GPA805HC0G denote AEC-Q101 qualification?

The "H" in GPA805HC0G explicitly indicates AEC-Q101 qualification, as defined in the Ordering Information section of the GPA801–GPA807 datasheet. This includes full stress testing (HTOL, temperature cycling, HTRB) and process control validation. The "C0G" suffix denotes halogen-free and RoHS-compliant packaging - both verified features of the GPA805HC0G device.
