Product details
Overview
GBJ604-F from Diodes Incorporated is a 6A standard recovery bridge rectifier with 400V maximum repetitive peak reverse voltage (VRRM), 1.0V forward voltage at 3A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and is rated for 170A peak surge current - ideal for AC/DC power supplies in industrial control and appliance mains input stages.
For engineers reviewing the GBJ604-F datasheet, GBJ604-F pinout, GBJ604-F application, or GBJ604-F equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (1.8°C/W junction-to-case), IFSM capability for inrush handling, and UL recognition (E95060) for safety-compliant designs.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a compact GBJ package with molded plastic housing and tin-plated leads. Its standard recovery characteristic (trr not specified, consistent with non-fast-recovery classification) supports line-frequency (50/60Hz) rectification without switching loss concerns.
The device operates across –55°C to +150°C junction temperature range and delivers 6.0A average rectified output current when mounted on a 75×75×1.6mm aluminum heatsink. Thermal resistance of 1.8°C/W enables predictable junction temperature rise under continuous load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands 400V repetitive reverse voltage, suitable for 230VAC mains with 2× safety margin |
| IF(AV) | 6.0 A - Continuous DC output current capability with heatsink at TJ = 150°C |
| VF @ 3A | 1.0 V max - Limits conduction loss to ≤3W per half-cycle at rated current |
| IFSM | 170 A peak - Handles cold-start inrush surges without failure |
| IR @ 25°C | 5 µA max - Ensures minimal standby power loss in off-state |
| RθJC | 1.8 °C/W - Enables thermal design with known junction-to-heatsink delta-T |
| VB | 400 V - Breakdown voltage matches VRRM rating, verified at 5µA IR |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 6A/400V rating, but GBU package (smaller footprint, lower IFSM = 150A) | Limited surge margin in high-inrush motor drives | Prefer for space-constrained PCBs where 20A IFSM headroom is acceptable |
| KBU6K (Comchip) | Identical GBJ package, same 6A/400V/170A specs, but no UL recognition | Not suitable for end-products requiring UL safety certification | Select only for cost-sensitive internal subsystems with self-certified safety |
Compared with GBU6K and KBU6K, GBJ604-F uniquely combines UL E95060 recognition, 170A surge rating, and GBJ mechanical robustness - making it optimal for certified industrial and white-goods designs where safety compliance and transient resilience are non-negotiable.

FAQ
What is the maximum operating temperature for GBJ604-F?
The GBJ604-F has a junction temperature range of –55°C to +150°C and a storage temperature range of –55°C to +150°C. Its 6.0A average current rating assumes operation at TJ = +150°C with proper heatsinking per the datasheet's 75×75×1.6mm aluminum plate condition.
Is GBJ604-F suitable for high-frequency switching applications?
No - GBJ604-F is a standard recovery bridge rectifier, not optimized for high-frequency operation. It lacks specified reverse recovery time (trr) and is intended for 50/60Hz line-frequency rectification. For SMPS or PFC stages, fast- or ultrafast-recovery alternatives are required.
Does GBJ604-F require a heatsink for 6A continuous operation?
Yes - the 6.0A IF(AV) rating is conditional on mounting to a 75×75×1.6mm aluminum heatsink. Without heatsinking, derating is necessary; at TA = +25°C free-air, the device supports only ~1.5A average current before exceeding TJ(max).
What does the "-F" suffix indicate in GBJ604-F?
The "-F" suffix denotes lead-free, RoHS-compliant finish with tin plating. It confirms compliance with EU RoHS Directives 2002/95/EC, 2011/65/EU, and 2015/863/EU, and indicates suitability for modern automated soldering processes per MIL-STD-202, Method 208.
