Product details
Overview
GPA804 C0G from Taiwan Semiconductor is an AEC-Q101-qualified, glass-passivated single-die standard rectifier in TO-220AC package, rated for 400 V repetitive peak reverse voltage (VRRM), 8 A average forward current (IF), and 150 A non-repetitive surge current (IFSM). It delivers low forward voltage (≤1.1 V at 8 A, 25°C) and ultra-low reverse leakage (≤5 µA at 25°C), targeting high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the GPA804 C0G datasheet, GPA804 C0G pinout, GPA804 C0G application, or GPA804 C0G equivalent, key selection criteria include its 400 V VRRM, TO-220AC thermal resistance (RθJC = 2.5 °C/W), junction temperature range (–55 to +150°C), and AEC-Q101 qualification status - all critical for automotive power supply and industrial SMPS design validation.
Technical Context
The GPA804 C0G is a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced moisture and contamination resistance. Its TO-220AC package features matte tin-plated leads compliant with J-STD-002 and JESD 201 Class 2 whisker testing.
Electrical behavior is defined by a typical junction capacitance of 50 pF at 1 MHz/4 V, forward voltage ≤1.1 V under 8 A/25°C pulsed conditions, and reverse leakage capped at 5 µA (25°C) and 100 µA (125°C), enabling stable operation in high-frequency switching topologies up to 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum reverse blocking voltage before breakdown; sets upper limit for input voltage in flyback or boost converters. |
| IF | 8 A - Continuous average forward current at case temperature ≤75°C; defines steady-state power handling in 12–48 V DC-DC stages. |
| IFSM | 150 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush current tolerance during cold-start in industrial PSUs. |
| VF | ≤1.1 V @ 8 A, 25°C - Low conduction loss directly reduces power dissipation and improves efficiency in high-current rectification paths. |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; enables direct heatsink mounting for thermal management without forced air in enclosed enclosures. |
| Junction Temp Range | –55 to +150°C - Wide operating range supports under-hood automotive environments and high-ambient industrial settings. |
Pinout & Package
TO-220AC package: 3-terminal, single-diode configuration with anode (pin 1), cathode (pin 2), and electrically connected tab (pin 3, cathode). Tab serves as primary heat path and must be electrically isolated from PCB ground unless circuit design requires cathode tie.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Lead) | Anode | Forward current entry point; connects to transformer secondary or switch node in bridgeless PFC designs. |
| Pin 2 (Lead) | Cathode | Forward current exit; ties to output capacitor positive rail or common return in center-tapped configurations. |
| Tab (Metal Surface) | Cathode (internally tied to Pin 2) | Primary thermal interface; requires insulating pad if mounted to grounded heatsink; contributes >90% of heat dissipation path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power modules requiring zero-defect reliability over 15-year service life under thermal cycling and vibration stress. |
| Glass-passivated junction | Eliminates risk of junction corrosion in humid or chemically aggressive environments (e.g., EV charging stations, outdoor telecom PSUs). |
| Low VF (≤1.1 V) | Reduces conduction loss by ≥15% vs. legacy 1N5408-class diodes at 8 A, directly improving system efficiency in 50–100 W SMPS. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU; enables export to EU, Japan, and South Korea without material declaration waivers. |
| 150 A IFSM | Withstands 3× rated current surges during startup or short-circuit events without degradation, reducing need for upstream fusing in compact designs. |

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 VRRM, 8 A IF, but higher VF (1.35 V typ), no AEC-Q101 qualification, TO-220AC package. | Suitable for commercial-grade industrial PSUs where automotive qualification is not required. | Select when cost sensitivity outweighs AEC-Q101 compliance and thermal performance is less constrained. |
| ON Semi MUR840 | 400 V VRRM, 8 A IF, ultrafast recovery (trr = 50 ns), but higher VF (1.25 V max), no AEC-Q101, TO-220AC. | Better suited for high-frequency (>300 kHz) PFC stages where reverse recovery time dominates losses. | Prefer when switching frequency exceeds 200 kHz and reverse recovery loss is dominant over conduction loss. |
Compared with STTH8R04DJF and MUR840, the GPA804 C0G offers lower conduction loss (≤1.1 V) and automotive qualification - making it optimal for thermally constrained, safety-critical 400 V rectification where long-term reliability trumps ultrafast recovery.

FAQ
What is the maximum junction temperature rating for GPA804 C0G?
The GPA804 C0G 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 high-ambient industrial enclosures without thermal derating below 8 A, provided case temperature remains ≤75°C per datasheet derating curves. The GPA804 C0G's RθJC of 2.5 °C/W supports this rating with appropriate heatsinking.
Is GPA804 C0G pin-compatible with other TO-220AC rectifiers like 1N5408?
No - while GPA804 C0G uses the standard TO-220AC outline, its internal single-die construction and cathode-tied tab differ from dual-diode or center-tap packages. The GPA804 C0G has anode (pin 1), cathode (pin 2), and cathode-connected tab (pin 3), whereas 1N5408 is a single-diode TO-220AC with identical pinout but lacks AEC-Q101 qualification and has higher VF. Layout reuse is possible only if thermal and qualification requirements align.
Does GPA804 C0G meet automotive qualification standards?
Yes - the GPA804 C0G is explicitly AEC-Q101 qualified, as confirmed in the manufacturer's G2103 datasheet revision. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock, validating suitability for automotive power conversion modules such as 12 V/48 V DC-DC units and onboard chargers. The "H" suffix denotes AEC-Q101 grade; GPA804 C0G carries this designation.
What is the reverse leakage current specification for GPA804 C0G at elevated temperature?
At 125°C and rated reverse voltage (400 V), the GPA804 C0G exhibits a maximum reverse leakage current (IR) of 100 µA, per the datasheet's Electrical Specifications table. At 25°C and 400 V, leakage is limited to 5 µA. These values reflect worst-case conditions under pulse testing (30 ms PW), ensuring predictable blocking behavior in high-temperature industrial and automotive applications where thermal runaway must be avoided.
How does the glass passivation in GPA804 C0G improve reliability compared to epoxy-passivated diodes?
Glass passivation in GPA804 C0G forms a hermetic, chemically inert barrier over the silicon junction, preventing moisture ingress, ion migration, and surface contamination that cause premature failure in humid or corrosive environments. Unlike organic epoxy layers, glass withstands prolonged exposure to condensation, salt fog, and thermal cycling without delamination - a key factor in automotive under-hood reliability and outdoor power electronics where GPA804 C0G is deployed.
