Product details
Overview
GBJ801 from Diodes Incorporated is a standard recovery 8A bridge rectifier with 100V peak reverse voltage (VRRM), 1.0V max forward voltage at 4A, 5µA max reverse leakage at 25°C, and 170A non-repetitive surge rating - used in AC/DC power supplies for industrial control panels requiring robust line-input rectification.
For engineers reviewing the GBJ801 datasheet, GBJ801 pinout, GBJ801 application, or GBJ801 equivalent, key selection criteria include VRRM margin for 120VAC input derating, thermal resistance (1.6°C/W junction-to-case), through-hole mounting torque limit (5.0 in-lbs), and UL recognition (E95060) for safety-compliant designs.
Technical Context
This single-phase full-wave bridge rectifier integrates four glass-passivated silicon diodes in one molded GBJ package. It operates across –55°C to +150°C junction temperature and delivers 8.0A average forward current when case temperature is maintained at +110°C.
The device exhibits low reverse leakage (5µA @ 25°C, 500µA @ 125°C) and high dielectric strength (1500VRMS isolation between AC terminals and case), enabling reliable operation in noisy industrial environments with transient voltage coupling risks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands repetitive reverse voltage up to 100V, suitable for 120VAC input after safety margin derating |
| IF(AV) | 8.0 A - Sustains continuous DC output current of 8A with proper heatsinking at TC = +110°C |
| VF Max | 1.0 V @ 4A - Forward drop limits conduction loss to ≤4W per half-cycle under typical load conditions |
| IR Max | 5 µA @ 25°C - Low leakage preserves efficiency in standby mode and reduces thermal drift in precision supplies |
| IFSM | 170 A - Handles inrush surges from cold-started transformers or capacitive inputs without failure |
| RθJC | 1.6 °C/W - Enables thermal design with aluminum plate heatsink (100mm × 100mm × 1.6mm) for stable junction temp |
Pinout & Package

FAQ
What is the maximum case temperature for continuous operation of GBJ801?
The GBJ801 supports continuous operation at an average forward current of 8.0A only when the case temperature (TC) is held at or below +110°C, as specified in its Absolute Maximum Ratings table. Exceeding this temperature requires derating per the published thermal curves.
Is GBJ801 RoHS compliant and lead-free?
Yes, GBJ801 features lead-free plating (tin finish) and complies with EU RoHS Directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. It is also halogen- and antimony-free per Diodes Incorporated's Green definition.
Can GBJ801 be mounted directly to a metal chassis?
No - although it has 1500VRMS dielectric strength, the GBJ801's plastic case is not rated for direct chassis contact under safety standards. Mounting requires insulating hardware or isolation washers to maintain creepage/clearance and meet UL E95060 requirements.
How does GBJ801 compare to fast recovery bridges like GBU8K?
GBJ801 uses standard recovery diodes (typical trr > 500ns), making it unsuitable for high-frequency SMPS. GBU8K offers fast recovery (~75ns) and lower EMI but lower surge rating (120A vs. 170A) and higher VF (1.1V). Choose GBJ801 for ruggedness in line-frequency applications; GBU8K for noise-sensitive switchers.
