Product details
Overview
GBJ804-F from Diodes Incorporated is a standard recovery 400V, 8A bridge rectifier in GBJ package, featuring 1.0V max forward voltage at 4A, 5µA max reverse leakage at 25°C, 1500VRMS dielectric strength, and 170A peak surge rating - used in AC/DC power supplies for industrial motor drives and HVAC control boards.
For engineers reviewing the GBJ804-F datasheet, GBJ804-F pinout, GBJ804-F application, or GBJ804-F equivalent, key selection criteria include VRRM=400V, IO=8.0A @ TC=110°C, thermal resistance RθJC=1.6°C/W, and through-hole mounting compatibility with #6 screw fastening.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a monolithic molded plastic GBJ package. It operates across -55°C to +150°C junction temperature range and delivers stable DC output under repetitive 8.3ms half-sine surge conditions up to 170A.
The device uses glass-passivated die construction to ensure low IR drift and high reliability in continuous conduction mode. Its 55pF typical junction capacitance per element supports moderate-frequency line rectification without excessive EMI generation in offline SMPS front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage ceiling (e.g., 280V RMS). |
| IO | 8.0 A @ TC = +110°C - Continuous average forward current capability when case is heatsinked to 110°C. |
| VF Max | 1.0 V @ IF = 4.0A - Forward voltage drop limiting conduction loss and thermal rise in high-current rectification. |
| IR Max | 5 µA @ VR = 400V, TA = +25°C - Low reverse leakage ensures minimal standby power loss in off-state. |
| IFSM | 170 A (8.3ms half-sine) - Peak non-repetitive surge current handling for inrush and fault transients. |
| RθJC | 1.6 °C/W - Junction-to-case thermal resistance enabling direct heatsink mounting for thermal management. |
| VB | 400 V - Breakdown voltage confirmed at IR = 5µA, ensuring margin against transient overvoltage. |
Pinout & Package
Package: GBJ - Molded plastic through-hole package with plated tin leads (RoHS-compliant), 6.6g weight, UL 94V-0 rated, designed for #6 screw mounting and 5.0 in-lbs max torque.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8J (ON Semiconductor) | VRRM = 600V, VF = 1.05V @ 4A, same 8A IO rating, GBU package (smaller footprint, lower RθJC = 1.4°C/W) | Preferred where higher voltage margin or tighter board space is required; not mechanically interchangeable due to different lead spacing. | Select when needing >400V margin or improved thermal performance on limited-area heatsinks. |
| KBU8B (Comchip) | VRRM = 800V, VF = 1.1V @ 4A, IO = 8A, KBU package (same pinout but taller profile, RθJC = 1.8°C/W) | Suitable for higher-voltage legacy systems; slightly higher conduction loss and thermal resistance limit high-ambient use. | Choose only if 800V rating is mandatory and board height allows taller package. |
Compared with GBJ804-F, GBU8J offers better thermal performance and smaller footprint but requires PCB redesign, while KBU8B trades higher voltage rating for increased VF and reduced thermal efficiency - making GBJ804-F optimal for cost-sensitive 400V-rated industrial power supplies with standardized GBJ mounting.

FAQ
What is the maximum operating temperature for GBJ804-F?
The GBJ804-F has a junction temperature range of -55°C to +150°C and is rated for 8.0A average forward current at TC = +110°C. Operation beyond +150°C risks permanent parametric shift or catastrophic failure due to silicon bandgap collapse and metallization migration.
Can GBJ804-F be used in surface-mount designs?
No - GBJ804-F is a through-hole device with axial leads designed for #6 screw mounting and mechanical retention on PCBs. It lacks SMD-compatible terminations or thermal pad structure, and its GBJ package outline does not conform to JEDEC MS-013 or other SMT standards.
Is GBJ804-F compliant with automotive qualification standards?
GBJ804-F is not AEC-Q101 qualified. While Diodes offers automotive-grade variants in the GBJ family, this specific part is intended for industrial and commercial applications. Automotive use requires explicit PPAP documentation and IATF 16949-manufactured lots, which must be requested separately.
How is the 1500VRMS dielectric strength tested?
The 1500VRMS rating is verified per UL 60747-5-1 using AC high-potential testing between all AC terminals collectively and the DC output terminals, applied for 1 minute at 50/60Hz with leakage current monitored below 1mA - confirming isolation integrity for basic insulation in Class I equipment.
