Product details
Overview
GBJ808-F from Diodes Incorporated is an 8A standard recovery bridge rectifier with 800V peak repetitive reverse voltage (VRRM), 1.0V max forward voltage at 4A, 5µA max reverse leakage at 25°C, and 170A non-repetitive surge rating - designed for AC/DC conversion in industrial power supplies and motor control input stages.
For engineers reviewing the GBJ808-F datasheet, GBJ808-F pinout, GBJ808-F application, or GBJ808-F equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (1.6°C/W junction-to-case), PCB-mount mechanical robustness, and UL recognition for safety-critical mains-input designs.
Technical Context
This single-phase full-wave bridge rectifier integrates four standard-recovery silicon diodes in a molded GBJ package with glass-passivated die construction. It delivers 8.0A average forward current at TC = +110°C and sustains 1500VRMS dielectric strength between case and terminals.
The device operates across –55°C to +150°C junction temperature range and exhibits 55pF typical capacitance per element at 1MHz/4V reverse bias - supporting stable performance in 50/60Hz and low-frequency switching applications without high-frequency parasitic resonance concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands peak reverse line voltage up to 800V, suitable for 400VAC RMS industrial mains inputs with safety margin. |
| IF(AV) | 8.0 A - Sustains continuous DC output current of 8A when mounted on 100×100×1.6mm Al heatsink at TC = +110°C. |
| VF Max | 1.0 V @ 4A - Low conduction loss enables efficient power conversion with <4W dissipation at rated load. |
| IR Max | 5 µA @ 25°C - Minimal reverse leakage preserves efficiency in high-impedance hold-up or sensing circuits. |
| IFSM | 170 A - Handles inrush surges from transformer energization or capacitor charging without failure. |
| RθJC | 1.6 °C/W - Enables thermal design with predictable junction temperature rise under steady-state load. |
Pinout & Package
Package: GBJ - Molded plastic through-hole package (UL 94V-0), 30.0mm × 20.0mm × 17.5mm nominal, with #6 screw mounting hole and plated tin leads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K (ON Semiconductor) | Same 800V VRRM, 8A IF(AV), but GBU package (smaller footprint, no screw mount) | Lacks #6 screw mounting and 1500VRMS isolation; unsuitable for high-vibration or safety-isolation-critical use | Select only if board space is constrained and mechanical mounting/strength is not required |
| KBP208 (Comchip) | 800V VRRM, 2A IF(AV) - lower current rating, TO-220FP package | Not rated for 8A continuous; requires parallel devices or derating for equivalent output | Use only for low-power auxiliary supplies where thermal management permits 2A operation |
Compared with GBU8K and KBP208, GBJ808-F uniquely combines 8A current capability, screw-mount mechanical stability, UL recognition, and 1500VRMS isolation - making it the only choice for industrial-grade, safety-certified, high-current AC/DC front-ends.

FAQ
What is the maximum operating temperature for GBJ808-F?
The GBJ808-F has a junction temperature range of –55°C to +150°C and is rated for 8.0A average forward current at case temperature (TC) of +110°C. Thermal design must ensure TC does not exceed +110°C under full load, using the specified 100mm × 100mm × 1.6mm aluminum heatsink for RθJC = 1.6°C/W.
Is GBJ808-F suitable for automotive applications?
GBJ808-F is not AEC-Q101 qualified and is not recommended for automotive powertrain or safety-critical systems. While it meets RoHS and UL requirements, Diodes explicitly states that automotive-grade variants require PPAP capability and IATF 16949 manufacturing - which this part does not carry per its datasheet and ordering information.
How is polarity marked on the GBJ808-F package?
Polarity is molded directly onto the plastic body: "+" and "–" symbols identify the positive and negative DC output terminals, while "~" symbols adjacent to AC1 and AC2 denote the AC input terminals. This marking is permanent, legible, and compliant with IPC standards for through-hole component identification.
What is the mounting torque specification for the GBJ808-F screw hole?
The GBJ808-F package includes a built-in #6 screw mounting hole with a maximum recommended mounting torque of 5.0 in-lbs (0.56 N·m). Exceeding this torque risks cracking the molded plastic case or deforming internal lead frames, potentially compromising dielectric strength or thermal performance.
