Product details
Overview
GBJ810 from Diodes Incorporated is a standard recovery 8A bridge rectifier with 1000V peak reverse voltage, 1.0V max forward voltage at 4A, 5µA max reverse leakage at 25°C, and 170A non-repetitive surge rating-designed for AC/DC power conversion in industrial power supplies and motor control circuits.
For engineers reviewing the GBJ810 datasheet, GBJ810 pinout, GBJ810 application, or GBJ810 equivalent, key selection criteria include VRRM = 1000V, IO = 8.0A @ TC = +110°C, thermal resistance RθJC = 1.6°C/W, and UL recognition under File E95060 for safety-critical board-level designs.
Technical Context
This single-phase full-wave bridge rectifier integrates four glass-passivated silicon diodes in a molded GBJ package. It operates across –55°C to +150°C junction temperature and delivers stable conduction with low reverse leakage (5 µA @ 25°C) and controlled capacitance (55 pF per element at 1 MHz).
The device supports through-hole mounting with #6 screw and 5.0 in-lbs max torque. Its 1500VRMS case dielectric strength and RoHS-compliant tin-plated leads meet industrial safety and environmental requirements without requiring external snubbers in typical line-frequency applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage the bridge withstands without breakdown during AC input cycles. |
| IO | 8.0 A @ TC = +110°C - Continuous average forward current deliverable when case temperature is held at 110°C. |
| VF Max | 1.0 V @ IF = 4A - Forward voltage drop per diode leg, defining conduction loss and thermal load at rated output. |
| IFSM | 170 A (8.3 ms half-sine) - Peak surge current capability, enabling robust startup and fault tolerance in transformer-fed supplies. |
| IR Max | 5 µA @ 25°C - Reverse leakage current per bridge leg, critical for low-power standby and high-impedance hold-up circuits. |
| RθJC | 1.6 °C/W - Junction-to-case thermal resistance, used to calculate temperature rise over heatsink when mounted on 100×100×1.6 mm Al plate. |
| VB | 1000 V - Breakdown voltage confirmed at IR = 5 µA, ensuring margin against transient overvoltage events. |
Pinout & Package

Use Scenario: Mains-powered control boards in washing machines and HVAC controllers requiring reliable, low-cost rectification. IC Role / Device Role / Timing Role: Primary rectifier supplying DC to microcontroller LDOs and relay drivers. Use Value: UL recognition (E95060) reduces end-product certification time and cost for Class II consumer appliances. | Use Scenario: Input stage of constant-voltage LED drivers for commercial lighting fixtures. IC Role / Device Role / Timing Role: Bridge rectifier feeding bulk capacitor and PFC controller IC. Use Value: Low 5 µA IR at 25°C minimizes no-load power loss, supporting Energy Star Tier 2 standby efficiency targets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU8K | Same 8A/1000V rating, but GBU package (smaller footprint, lower I²t = 100 A²s). | Limited surge robustness in high-inrush transformer designs. | Prefer for space-constrained PCBs where surge margin is secondary to size. |
| ON Semiconductor GBPC810 | Identical electrical specs, but GBPC package (larger, higher thermal mass, RθJC = 1.8°C/W). | Better thermal stability under sustained 8A load; requires more board area. | Choose when continuous full-load operation at elevated ambient temperatures is expected. |
Compared with GBU8K and GBPC810, GBJ810 offers optimal balance of surge margin (170A), thermal performance (RθJC = 1.6°C/W), and UL recognition-making it preferred for industrial-grade AC/DC front-ends where reliability and certification matter most.

FAQ
What is the maximum operating temperature for GBJ810?
The GBJ810 has a specified junction temperature range of –55°C to +150°C and a storage temperature range matching that span. Its 8.0A average forward current rating is defined at TC = +110°C, meaning the case must be maintained at or below this temperature for full-rated operation. Thermal design must account for RθJC = 1.6°C/W and heatsink interface conditions.
Does GBJ810 require a heatsink in typical applications?
A heatsink is required when operating near full rated current (8.0A) or in elevated ambient temperatures. With RθJC = 1.6°C/W and a typical system RθCA of 10–20°C/W, junction temperature exceeds 150°C without thermal management at >3–4A continuous load. For intermittent or low-duty-cycle use below 3A, PCB copper pour may suffice.
Is GBJ810 compliant with automotive qualification standards?
No-GBJ810 is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade variants require separate change control, PPAP capability, and IATF 16949 manufacturing; standard GBJ810 is intended for industrial and commercial applications. For automotive use, contact Diodes directly for qualified alternatives.
How is polarity marked on the GBJ810 package?
Polarity is molded directly onto the plastic body: the "+" and "–" symbols are embossed adjacent to their respective output terminals, and the AC input terminals are labeled "~" or implied by symmetric placement opposite the DC outputs. The marking "GBJ810" appears on the top surface, with date code (YWW) elsewhere on the body.
