Product details
Overview
GPA802H from Taiwan Semiconductor is an AEC-Q101-qualified 100V, 8A standard rectifier diode in TO-220AC package, featuring low forward voltage (1.1 V max at 8 A), high surge capability (150 A), and glass-passivated junction for automotive and industrial power conversion.
For engineers reviewing the GPA802H datasheet, GPA802H pinout, GPA802H application, or GPA802H equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (2.5 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification status for under-hood reliability.
Technical Context
The GPA802H is a single-die, unidirectional standard rectifier optimized for line-frequency and switching-mode power supplies. Its glass-passivated chip junction ensures stable reverse leakage (<5 µA at 25 °C) and robustness against humidity and contamination.
Designed for high-current DC/DC conversion, it delivers 8 A average forward current with 150 A non-repetitive surge rating (8.3 ms half-sine), and exhibits 50 pF junction capacitance at 4 V reverse bias-enabling predictable EMI behavior in flyback and boost topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in bridge or freewheeling configurations |
| IF | 8 A - Continuous average forward current at case temperature ≤75 °C; determines heatsink sizing in steady-state operation |
| IFSM | 150 A - Peak non-repetitive surge current (8.3 ms); supports inrush and fault-current handling without failure |
| VF | ≤1.1 V @ 8 A, 25 °C - Low conduction loss improves efficiency in 12–48 V input converters |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; enables direct mounting to heatsink with predictable temperature rise |
| Junction temp | –55 to +150 °C - Wide operating range supports under-hood automotive and industrial ambient conditions |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8L06D | 600 V VRRM, 8 A, 1.7 V VF max, TO-220AC, not AEC-Q101 qualified | Higher voltage rating but higher conduction loss; suited for universal-input SMPS, not automotive | Select when >100 V blocking required and AEC-Q101 not mandated |
| ON Semi MUR8100E | 1000 V VRRM, 8 A, 1.75 V VF max, TO-220AC, AEC-Q101 qualified | Same qualification level but higher VF and lower surge rating (100 A); optimized for high-voltage PFC stages | Prefer for 400–800 V DC link applications where surge margin is secondary to voltage headroom |
Compared with STTH8L06D and MUR8100E, the GPA802H uniquely balances 100 V blocking, AEC-Q101 compliance, and low 1.1 V VF-making it optimal for cost-sensitive, thermally constrained 12–48 V automotive and industrial converters requiring long-term reliability without over-spec'ing voltage.

FAQ
What is the maximum junction temperature rating for GPA802H?
The GPA802H has a maximum junction temperature (TJ) of +150 °C and a minimum of –55 °C. This wide range allows operation in under-hood automotive environments and industrial enclosures without forced air cooling. The GPA802H maintains specified electrical parameters across this full range when derated per its forward current derating curve.
Is GPA802H pin-compatible with other TO-220AC rectifiers like 1N5408?
Yes, the GPA802H uses the standard TO-220AC outline with anode–cathode–tab pinout identical to 1N5408 and MUR8xx series. However, unlike 1N5408, the GPA802H features AEC-Q101 qualification, lower VF (1.1 V vs. 1.2 V), and higher IFSM (150 A vs. 200 A but with tighter pulse definition).
Does GPA802H require a heatsink in 8 A continuous operation?
Yes - at 8 A continuous forward current, the GPA802H dissipates ~8.8 W (based on 1.1 V VF). With RθJC = 2.5 °C/W and typical RθCA > 20 °C/W for bare mounting, a heatsink is required to maintain TJ ≤150 °C. Derating to 6 A is recommended without heatsinking.
What does the "H" suffix signify in GPA802H?
The "H" suffix in GPA802H indicates full AEC-Q101 qualification per Rev D, including stress testing for temperature cycling, humidity bias, and high-temperature reverse bias. This distinguishes it from the non-H variant (GPA802), which lacks automotive-grade validation and is intended for commercial/industrial use only.
How does GPA802H's junction capacitance affect high-frequency switching performance?
The GPA802H exhibits 50 pF junction capacitance at 4 V reverse bias (1 MHz), which influences reverse recovery behavior and EMI generation. In 100 kHz–500 kHz SMPS designs, this value enables predictable snubber design and limits displacement current during turn-off-critical for maintaining stability in flyback and forward converters using the GPA802H.
