Product details

Overview

GPA801 from Taiwan Semiconductor is a single-die, glass-passivated standard rectifier diode in TO-220AC package, rated for 50 V repetitive peak reverse voltage (V_RRM), 8 A average forward current (I_F), and 150 A non-repetitive surge current (I_FSM), optimized for DC-DC converters and switching-mode power supplies.

For engineers reviewing the GPA801 datasheet, GPA801 pinout, GPA801 application, or GPA801 equivalent, key selection criteria include its 1.1 V max forward voltage at 8 A, 2.5 °C/W junction-to-case thermal resistance, 5 µA max reverse leakage at 25 °C, TO-220AC mechanical compatibility, and AEC-Q101 qualification availability (GPA801H variant).

Technical Context

The GPA801 operates as a unidirectional power rectifier with a single PN junction, designed for line-frequency and high-frequency switching applications up to 1 MHz. Its glass passivation ensures stable surface characteristics under thermal cycling and humidity stress.

Thermal performance is defined by R_θJC = 2.5 °C/W, enabling reliable operation at T_J up to +150 °C when mounted on a heatsink. Junction capacitance is specified at 50 pF (1 MHz, 4 V reverse bias), supporting predictable snubber design in flyback and forward converters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum reverse voltage the device blocks continuously without breakdown
I_F	8 A - Continuous average forward current rating at case temperature ≤ 75 °C
I_FSM	150 A - Peak non-repetitive surge current (8.3 ms half-sine) for transient overload handling
V_F (max)	1.1 V - Forward voltage drop at 8 A and 25 °C, directly impacting conduction loss in power stage
R_θJC	2.5 °C/W - Thermal resistance from junction to case, critical for heatsink sizing in 8 A operation
C_J	50 pF - Junction capacitance at 1 MHz / 4 V, influencing high-frequency switching noise and EMI filter design

Pinout & Package

Package: TO-220AC - 3-lead, single-ended, through-hole package with isolated tab (cathode-connected tab); matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Input terminal for forward conduction	Connected to AC or switching node side; requires PCB trace capable of 8 A continuous current
Cathode	Output terminal for forward conduction	Internally bonded to metal tab; electrically common with mounting surface - isolation required if tab is grounded
Tab (Cathode)	Thermal and electrical cathode path	Serves dual role: primary heat dissipation path and low-inductance cathode connection; must be electrically isolated unless system ground reference permits

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH8R06D (STMicroelectronics)	600 V V_RRM, 8 A I_F, 1.75 V V_F (max), TO-220AC, no AEC-Q101 option	Higher voltage rating but higher forward drop; not qualified for automotive use	Select when >50 V blocking is needed and AEC-Q101 is not required

FAQ

What is the maximum junction temperature rating for the GPA801?

The GPA801 has a maximum junction temperature (T_J) rating of +150 °C, verified per absolute maximum ratings table. This allows sustained operation in high-ambient environments when properly heatsinked. Derating curves in the GPA801 datasheet show usable forward current decreases linearly above 75 °C case temperature. Thermal design must respect R_θJC = 2.5 °C/W to avoid exceeding T_J = 150 °C under full 8 A load.

Is the GPA801 pin-compatible with other TO-220AC rectifiers like the 1N5408?

Yes, the GPA801 uses the standard TO-220AC outline with anode, cathode, and cathode-connected tab pinout identical to 1N5408 and similar 3-lead rectifiers. However, the GPA801 offers superior surge capability (150 A vs. 200 A for 1N5408), lower V_F (1.1 V vs. ~1.2 V), and glass passivation - making it a performance upgrade, not just a footprint replacement.

Does the GPA801 have automotive qualification?

The base GPA801 is not AEC-Q101 qualified, but the GPA801H variant is explicitly qualified per AEC-Q101 Rev D. The "H" suffix denotes automotive-grade screening including HTGB, HTRB, and temperature cycling. For automotive applications such as onboard chargers or body control modules, GPA801H must be specified - the standard GPA801 is intended for industrial and commercial use.

What is the reverse leakage current specification for the GPA801 at elevated temperature?

At T_J = 125 °C and rated V_R, the GPA801 exhibits a maximum reverse leakage current (I_R) of 100 µA, per electrical specifications table. This is significantly higher than the 5 µA limit at 25 °C, reflecting expected thermal generation in the depletion region. Designers must verify that this leakage does not compromise regulation or efficiency in high-temperature, high-impedance feedback networks.

How does the junction capacitance of the GPA801 affect high-frequency switching performance?

The GPA801 has a typical junction capacitance (C_J) of 50 pF at 1 MHz and 4 V reverse bias. This value influences turn-on loss and EMI generation during hard-switching transitions. In 100 kHz+ converters, C_J contributes to capacitive current spikes; designers should account for it in snubber sizing and layout to minimize ringing. Lower C_J than many legacy rectifiers improves high-frequency rectification fidelity.
