Taiwan Semiconductor Corporation GPA805H

Overview

GPA805H from Taiwan Semiconductor is an AEC-Q101-qualified 600 V, 8 A standard rectifier diode in TO-220AC package, designed for high-reliability power conversion stages in automotive and industrial DC/DC converters and switching inverters, with 150 A surge capability and 1.1 V max forward voltage at 8 A.

For engineers reviewing the GPA805H datasheet, GPA805H pinout, GPA805H application, or GPA805H equivalent, key selection criteria include peak reverse voltage (600 V), forward current rating (8 A), AEC-Q101 qualification status, thermal resistance (2.5 °C/W), and TO-220AC mechanical compatibility with heatsink mounting.

Technical Context

The GPA805H is a single-die, glass-passivated standard rectifier optimized for unidirectional conduction in medium-voltage, medium-current power supplies. Its 600 V V_RRM and 150 A I_FSM support robust operation under transient overloads typical in SMPS front-end rectification.

Thermal performance is defined by a junction-to-case resistance of 2.5 °C/W and maximum junction temperature of +150 °C, enabling stable operation in constrained thermal environments when mounted to a heatsink. Reverse leakage remains ≤5 µA at 25 °C and ≤100 µA at 125 °C under rated VR.

FAQ

What is the peak repetitive reverse voltage rating of the GPA805H?

The GPA805H has a peak repetitive reverse voltage (V_RRM) rating of 600 V. This value is specified in the Absolute Maximum Ratings table and confirmed across all official documentation versions (G2103). It defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. The GPA805H is part of the GPA801–GPA807 series, where "805" explicitly denotes the 600 V variant, and this rating is validated under standard test conditions per JEDEC guidelines.

Is the GPA805H AEC-Q101 qualified, and what does the "H" suffix indicate?

Yes, the GPA805H is AEC-Q101 qualified. The "H" suffix in the ordering code explicitly denotes AEC-Q101 qualification, as stated in the Ordering Information section of the datasheet (Version G2103). This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), ensuring suitability for automotive power electronics. The GPA805H shares this qualification with other "H"-suffixed variants in the GPA801–GPA807 family.

What is the forward voltage drop of the GPA805H at rated current?

The GPA805H has a maximum forward voltage (V_F) of 1.1 V at 8 A forward current and 25 °C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At higher temperatures (e.g., 125 °C), V_F decreases slightly due to semiconductor physics, but the 1.1 V max remains the design-limiting value for worst-case conduction loss calculation in the GPA805H.

What is the thermal resistance from junction to case for the GPA805H?

The junction-to-case thermal resistance (R_θJC) of the GPA805H is 2.5 °C/W, as specified in the Thermal Performance section. This value applies to the TO-220AC package with proper mounting pressure and thermal interface. It enables precise heatsink sizing: for example, at 8 A and 1.1 V V_F, power dissipation is ~8.8 W, resulting in a 22 °C temperature rise from junction to case-critical for maintaining T_J ≤ 150 °C in the GPA805H.

Does the GPA805H have a cathode-connected metal tab, and how should it be mounted?

Yes, the GPA805H uses a TO-220AC package with the cathode electrically connected to the metal tab. When mounting, the tab must be thermally coupled to a heatsink using appropriate hardware and thermal interface material. If the heatsink is grounded or at a different potential, an insulating washer and shoulder washer are required to prevent shorting. Polarity is marked on the device body, and the tab must be treated as a live cathode terminal-not a ground reference-in the GPA805H layout.
