Diodes Incorporated GBJ802

Overview

GBJ802 from Diodes Incorporated is a standard recovery 8A bridge rectifier with 200V maximum repetitive peak reverse voltage (VRRM), 1.0V forward voltage at 4A, and 5µA reverse leakage current at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and is rated for 170A non-repetitive surge current - ideal for AC/DC power supplies in industrial control and appliance mains input stages.

For engineers reviewing the GBJ802 datasheet, GBJ802 pinout, GBJ802 application, or GBJ802 equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (1.6°C/W junction-to-case), mounting torque limit (5.0 in-lbs), and UL recognition (E95060) for safety-compliant designs.

Technical Context

This discrete bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with molded GBJ package. Its standard recovery characteristic (typical reverse recovery time not specified but implied by "standard recovery" classification) supports line-frequency (50/60Hz) rectification without high-frequency switching losses.

The device operates across –55°C to +150°C junction temperature range and delivers 8.0A average forward output current when case temperature is maintained at +110°C. Thermal performance relies on mechanical mounting to an aluminum heatsink (100mm × 100mm × 1.6mm) per R_θJC specification.

The GBJ series belongs to Diodes' standard recovery bridge rectifier product line, engineered for cost-effective, high-reliability AC/DC conversion in mains-powered equipment where switching noise and ultra-fast recovery are not required.

FAQ

What is the maximum operating temperature for GBJ802?

The GBJ802 has a 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 specified at TC = +110°C, meaning the case must be actively cooled to remain at or below this temperature under full load to avoid exceeding the 150°C absolute maximum junction temperature.

Is GBJ802 suitable for high-frequency switching applications?

No - GBJ802 is a standard recovery bridge rectifier, not optimized for high-frequency operation. Its unspecified but relatively long reverse recovery time makes it unsuitable for PWM frequencies above 20kHz. It is intended for 50/60Hz line-frequency rectification where low conduction loss and surge robustness outweigh switching speed requirements.

Does GBJ802 require a heatsink in all applications?

A heatsink is required to sustain 8.0A average current - the 1.6°C/W R_θJC rating assumes mounting on a 100mm × 100mm × 1.6mm aluminum plate. At lower currents (e.g., ≤3A), natural convection may suffice depending on ambient temperature and PCB copper area, but thermal validation is mandatory per application conditions.

How is polarity marked on the GBJ802 package?

Polarity is molded directly onto the plastic body: the "+" symbol identifies the positive DC output terminal, "–" marks the negative DC output terminal, and the two unlabeled terminals are the AC inputs (AC1 and AC2). This marking is visible on the top surface adjacent to respective leads and complies with JEDEC-standard bridge rectifier orientation conventions.
