Product details
Overview
GBJ1004 from Diodes Incorporated is a 10A standard recovery bridge rectifier with 400V peak repetitive reverse voltage (VRRM), 1.05V max forward voltage at 5A, 10µA max reverse leakage at 25°C, and 170A non-repetitive surge rating - used in AC/DC power supplies for industrial motor drives and HVAC control boards.
For engineers reviewing the GBJ1004 datasheet, GBJ1004 pinout, GBJ1004 application, or GBJ1004 equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (1.4°C/W junction-to-case), through-hole mounting torque limit (5.0 in-lbs), and UL recognition (E95060) for safety-critical power conversion designs.
Technical Context
This single-phase full-wave bridge rectifier integrates four glass-passivated silicon diodes in a molded GBJ package. It operates across –55°C to +150°C junction temperature range and delivers 10A average forward current when case temperature is maintained at +110°C.
The device exhibits 55pF typical capacitance per element at 1MHz/4V reverse bias and supports 1500VRMS dielectric strength between case and terminals - enabling reliable isolation in mains-connected equipment where creepage and clearance compliance is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands 400V peak reverse voltage during negative half-cycles without breakdown |
| IF(AV) | 10 A - Sustains 10A average forward current with TC = +110°C and adequate heatsinking |
| VF Max | 1.05 V @ 5A - Limits conduction loss to ≤5.25W per half-cycle under rated DC load |
| IR Max | 10 µA @ 25°C - Ensures minimal standby power loss in off-state high-impedance circuits |
| IFSM | 170 A - Survives 8.3ms AC line surge events such as cold-start inrush or lightning-induced transients |
| RθJC | 1.4 °C/W - Requires ≥7.1 cm² copper area (150mm × 150mm × 1.6mm) to maintain TJ ≤150°C at full load |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU1004 | Same VRRM (400V) and IF(AV) (10A), but GBU package has lower RθJC (1.2°C/W) and higher IFSM (200A) | Preferred where higher surge immunity or tighter thermal budget is required | Select GBU1004 for space-constrained designs needing improved thermal performance without changing footprint |
| KBPC1004 | Same electrical ratings, but KBPC package uses larger body (42 × 25 × 22 mm) and requires different mounting hardware | Suitable for legacy designs using KBPC footprints or where higher creepage distance is mandated | Choose KBPC1004 only when existing PCB layout or safety standards require its larger isolation distances |
Compared with GBU1004 and KBPC1004, the GBJ1004 offers optimized balance of thermal performance, surge capability, and compact through-hole packaging - making it ideal for new industrial and commercial power supply designs where board space and mounting simplicity are prioritized.

FAQ
What is the maximum case temperature for continuous 10A operation?
The GBJ1004 sustains 10A average forward current only when case temperature (TC) is held at +110°C or below. Exceeding this limit risks thermal runaway due to increased forward voltage drop and leakage current. Derating is required above +110°C - e.g., 7.5A at TC = +125°C - per the datasheet's thermal derating curve.
Is the GBJ1004 suitable for use in automotive applications?
The GBJ1004 is not AEC-Q101 qualified and lacks PPAP documentation or IATF 16949 manufacturing certification. While it meets basic electrical and thermal specs, Diodes explicitly states that automotive-grade variants require direct consultation with their representatives - making it unsuitable for safety-critical vehicle systems without additional qualification.
How does the GBJ package differ from the GBU package in thermal performance?
The GBJ1004 has a junction-to-case thermal resistance (RθJC) of 1.4°C/W, while the GBU1004 achieves 1.2°C/W due to enhanced internal leadframe geometry and die attach. This 0.2°C/W difference translates to ~2°C lower junction temperature at 10A with identical heatsinking - critical for designs operating near thermal limits.
Can the GBJ1004 be mounted directly to a metal chassis without insulation?
No. The GBJ1004's case is electrically connected to the cathode common (–) terminal. Mounting directly to a grounded chassis creates a short circuit unless an insulating shoulder washer and isolated screw are used. UL 1557-compliant mounting requires 0.5mm minimum insulator thickness and verification of dielectric strength after assembly.
