Product details
Overview
GPA804H from Taiwan Semiconductor is an AEC-Q101-qualified 400V, 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 GPA804H datasheet, GPA804H pinout, GPA804H application, or GPA804H equivalent, key selection factors include repetitive peak reverse voltage (400 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 GPA804H is a single-die, unidirectional standard rectifier optimized for line-frequency and switching-mode power supplies. Its glass-passivated junction ensures stable reverse leakage (<5 µA at 25 °C) and robustness against humidity and contamination.
Thermally, it delivers 2.5 °C/W junction-to-case resistance in TO-220AC, enabling reliable 8 A continuous conduction with proper heatsinking. The device supports 8.3 ms half-sine surge up to 150 A without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in AC/DC front-ends |
| IF | 8 A - Continuous forward current rating; determines minimum heatsink size for steady-state operation |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms); supports inrush and fault-current handling in SMPS |
| VF | ≤1.1 V @ 8 A, 25 °C - Low conduction loss; reduces power dissipation and improves efficiency in rectification stages |
| RθJC | 2.5 °C/W - Thermal resistance from junction to case; enables direct mounting to heatsink without thermal interface material compromise |
| TJ max | +150 °C - Maximum operating junction temperature; allows use in high-ambient environments like engine compartments |
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; must withstand full reverse voltage when off |
| Cathode | Output terminal for forward conduction | Electrically tied to metal tab; requires isolation from heatsink unless system ground reference permits |
| Tab (Cathode) | Thermal and electrical cathode connection | Primary heat path to heatsink; electrically active - insulation required if mounted to non-grounded chassis |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including temperature cycling, mechanical shock, and humidity exposure |
| Glass-passivated junction | Prevents moisture ingress and surface leakage; maintains stable IR <5 µA at 25 °C over lifetime |
| Low VF (≤1.1 V) | Reduces conduction losses by ~15% vs. legacy 1.3 V rectifiers at 8 A, lowering thermal stress in compact designs |
| High IFSM (150 A) | Withstands 60 Hz line surges and SMPS startup transients without bond-wire fusing or parameter shift |
| RoHS & halogen-free | Complies with IEC 61249-2-21; suitable for automotive OEMs requiring full material declaration and WEEE compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R04DJF | 400 V, 8 A, TO-220AC, VF = 1.15 V max, non-AEC-Q101 | Lacks automotive qualification; higher VF increases conduction loss by ~50 mW at 8 A | Preferred for industrial-only designs where AEC-Q101 is not mandated |
| ON Semi MUR840E | 400 V, 8 A, TO-220AC, ultrafast recovery (trr = 60 ns), VF = 1.25 V max | Designed for higher-frequency switching; higher VF and cost trade off for reduced EMI in PFC stages | Select when fast recovery is required and conduction loss budget allows +0.15 V penalty |
Compared with STTH8R04DJF and MUR840E, the GPA804H uniquely combines AEC-Q101 qualification, 1.1 V VF ceiling, and 2.5 °C/W thermal resistance - making it optimal for automotive and thermally constrained industrial rectification where reliability and efficiency are jointly critical.

FAQ
Is GPA804H pin-compatible with other TO-220AC rectifiers like UF4007 or 1N5408?
Yes, GPA804H uses standard TO-220AC pinout (anode–cathode–tab), matching mechanical and electrical footprint of UF4007 and 1N5408. However, GPA804H offers higher VRRM (400 V vs. 1000 V for UF4007, 1000 V for 1N5408), lower VF (≤1.1 V vs. ≥1.7 V), and AEC-Q101 qualification - making GPA804H suitable for higher-efficiency, automotive-grade replacements where thermal performance matters.
What is the maximum continuous forward current rating for GPA804H at 100°C case temperature?
Per the forward current derating curve in the GPA801–GPA807 datasheet, GPA804H supports 6.4 A continuous forward current at 100°C case temperature. This is derived from linear derating from 8 A at 25°C to 0 A at 150°C, yielding 8 A × (1 − (100−25)/125) = 6.4 A. Adequate heatsinking is required to maintain case temperature ≤100°C for sustained 6.4 A operation.
Does GPA804H have a specified reverse recovery time (trr)?
No, GPA804H is a standard (non-fast or ultrafast) rectifier and does not specify reverse recovery time in its datasheet. It is characterized for 50/60 Hz and low-frequency switching applications. For circuits requiring trr < 200 ns, consider alternatives like MUR840E or STTH8R04DJF - but note GPA804H's lower VF and AEC-Q101 qualification make it preferable where recovery speed is not critical.
Can GPA804H be used in parallel configurations to increase current handling?
GPA804H may be paralleled only with careful thermal and electrical balancing: matched VF bins, symmetrical PCB layout, shared heatsink, and individual current-sense resistors. Due to positive VF temperature coefficient, inherent current sharing is possible, but mismatched thermal paths can cause current hogging. For >8 A requirements, consult TSC's application note AN-GPA-01 before implementing parallel GPA804H units.
What does the "H" suffix in GPA804H signify, and is it reflected in the device marking?
The "H" suffix in GPA804H indicates AEC-Q101 qualification per the ordering information table. Devices marked "GPA804" on the package are the standard version; "GPA804H" devices carry identical marking but are sourced from AEC-Q101-qualified wafer lots and undergo additional automotive screening. Traceability documentation confirms H-suffix units meet stress-test requirements including HTSL, TC, and uHAST.
