Taiwan Semiconductor Corporation GPA803

Overview

GPA803 from Taiwan Semiconductor is a single-die, glass-passivated standard rectifier diode in TO-220AC package, rated for 200 V repetitive peak reverse voltage (V_RRM), 8 A average forward current (I_F), and 150 A non-repetitive surge current (I_FSM). It delivers low forward voltage (1.1 V max at 8 A, 25°C) and ultra-low reverse leakage (5 µA max at 25°C), targeting high-efficiency DC-DC converters and switching inverters.

For engineers reviewing the GPA803 datasheet, GPA803 pinout, GPA803 application, or GPA803 equivalent, key selection criteria include its 200 V V_RRM, TO-220AC thermal resistance (2.5 °C/W), AEC-Q101 qualification option (GPA803H), junction temperature range (–55 to +150 °C), and halogen-free, RoHS-compliant construction.

Technical Context

The GPA803 operates as a unidirectional power rectifier with a single P-N junction optimized for medium-voltage, high-current switching applications. Its glass passivation ensures stable surface characteristics under thermal cycling and humidity stress, while the TO-220AC case enables direct heatsink mounting with verified 2.5 °C/W junction-to-case thermal resistance.

Electrical behavior is defined by tight control of forward conduction (V_F ≤ 1.1 V @ 8 A) and reverse blocking (I_R ≤ 5 µA @ 200 V, 25°C), supported by low junction capacitance (50 pF @ 4 V). The device sustains 150 A surge peaks (8.3 ms half-sine) without degradation, making it suitable for transient-heavy industrial power stages.

Supply support for GPA803 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and power discrete manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and automotive markets since 1979.

The GPA801–GPA807 family was designed specifically for cost-sensitive, high-reliability rectification in medium-voltage switching power supplies-emphasizing low V_F, robust surge handling, and AEC-Q101 readiness for automotive auxiliary systems.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for GPA803?

The GPA803 has a V_RRM of 200 V, as specified in the Absolute Maximum Ratings table. This value defines the highest reverse voltage the device can block continuously without avalanche breakdown. It is validated across the full operating temperature range and forms the basis for safe derating in circuit design-e.g., selecting 200 V devices for systems with ≤140 V DC bus or ≤100 V RMS AC input.

Is GPA803 available in an AEC-Q101 qualified version?

Yes, the AEC-Q101 qualified version of GPA803 is designated GPA803H and shares identical electrical and thermal specifications. The "H" suffix indicates full qualification per AEC-Q101 stress test requirements-including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-making GPA803H suitable for automotive power modules and infotainment systems.

What is the forward voltage (V_F) of GPA803 at rated current?

The GPA803 exhibits a maximum forward voltage of 1.1 V at 8 A forward current and 25°C junction temperature, measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures (e.g., 125°C), V_F decreases slightly due to semiconductor physics, but system-level thermal design must ensure case temperature stays within limits to maintain this performance.

Does GPA803 have a thermally isolated package?

No, the GPA803 uses a TO-220AC package where the metal tab is electrically connected to the cathode terminal. This configuration provides optimal thermal conduction to a heatsink but requires electrical isolation (e.g., mica washer or insulating pad) if the heatsink is grounded or at a different potential. The tab is not internally insulated.

What is the junction-to-case thermal resistance (R_θJC) of GPA803?

The GPA803 has a typical junction-to-case thermal resistance of 2.5 °C/W, measured from die junction to the mounting surface of the TO-220AC tab. This value is critical for calculating maximum allowable power dissipation: P_max = (T_J(max) − T_C) / R_θJC. For example, at 100°C case temperature, max continuous power is (150 − 100) / 2.5 = 20 W.
