Product details
Overview
GBJ604 from Diodes Incorporated is a 6A standard recovery bridge rectifier in GBJ package, rated for 400V repetitive peak reverse voltage (VRRM), 1.0V max forward voltage at 3A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and 170A peak surge capability - used in AC/DC power supplies for industrial control panels and LED drivers.
For engineers reviewing the GBJ604 datasheet, GBJ604 pinout, GBJ604 application, or GBJ604 equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (1.8°C/W junction-to-case), IFSM rating 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 common cathode/anode configuration, enabling unidirectional DC output from AC input without external wiring. Its standard recovery characteristic (trr not specified but typical for standard recovery bridges) supports line-frequency (50/60 Hz) operation with low conduction loss and robust surge immunity.
The device operates across –55°C to +150°C junction temperature range and is mounted via through-hole #6 screw with 5.0 in-lbs max torque. Thermal performance assumes use of a 75 × 75 × 1.6 mm aluminum heatsink, delivering 1.8°C/W junction-to-case thermal resistance per element.
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 - Average rectified current per element with heatsink at TJ = 150°C |
| VF Max | 1.0 V @ 3A - Low conduction loss reduces power dissipation in continuous-duty power supplies |
| IFSM | 170 A peak (8.3 ms) - Handles high inrush currents during cold-start of transformers and capacitive inputs |
| IR Max | 5 µA @ 25°C - Minimal reverse leakage preserves efficiency in high-impedance hold-up circuits |
| RθJC | 1.8 °C/W - Enables predictable thermal design when mounted on standardized 75×75 mm heatsink |
| CT | 55 pF @ 1 MHz, 4V - Low junction capacitance minimizes EMI generation in switching-adjacent layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBPC604 | Same 400V VRRM, 6A IF(AV), but higher VF (1.1V max @ 3A) and 2.2°C/W RθJC | Limited thermal headroom in compact heatsink designs; requires larger PCB copper area | Prefer GBJ604 where thermal management is constrained or lower conduction loss is critical |
| ON Semiconductor GBPC604 | Identical ratings but non-UL-recognized; no E95060 file number; RoHS compliant only (no Halogen-Free claim) | Not acceptable for end-equipment requiring UL Component Recognition | Select GBJ604 when UL listing or halogen-free compliance is mandated by OEM safety or environmental specs |
Compared with GBPC604 variants, GBJ604 offers superior thermal resistance (1.8 vs. ≥2.2°C/W), lower forward voltage (1.0V vs. 1.1V), and formal UL recognition - making it preferred for space-constrained, safety-certified, and thermally demanding industrial power designs.

FAQ
What is the maximum operating junction temperature for GBJ604?
The GBJ604 has a specified operating junction temperature range of –55°C to +150°C. This allows reliable operation in high-ambient environments such as enclosed industrial enclosures or LED streetlight housings, provided thermal design maintains TJ ≤ 150°C using the 1.8°C/W RθJC value and appropriate heatsinking.
Is GBJ604 suitable for use in automotive applications?
GBJ604 is not AEC-Q101 qualified and is not intended for automotive powertrain or safety-critical systems. While it meets RoHS and UL requirements, Diodes explicitly states that automotive-grade parts require separate qualification (PPAP, IATF 16949, AEC-Q101), and GBJ604 is not listed in their automotive product portfolio.
Does GBJ604 have a center-tap configuration?
No, GBJ604 is a single-phase full-wave bridge rectifier with four terminals: two AC inputs (~), one positive DC output (+), and one negative DC output (–). It does not provide or support center-tapped transformer configurations - those require dual-diode or dual-common packages like KBP or KBU series.
How is polarity marked on the GBJ604 package?
Polarity is molded directly onto the plastic body: "+" and "–" symbols are embossed adjacent to their respective DC output terminals, and the AC input terminals are marked with "~". This marking is permanent, solvent-resistant, and visible after soldering - eliminating reliance on PCB silkscreen for correct orientation.
