Product details
Overview
GBJ1504 from Diodes Incorporated is a 15A standard recovery bridge rectifier with 400V maximum repetitive peak reverse voltage (VRRM), 1.05V forward voltage at 7.5A, and 10µA reverse leakage current at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and is rated for 240A peak surge current - used in AC/DC power supplies for industrial motor drives and HVAC control boards.
For engineers reviewing the GBJ1504 datasheet, GBJ1504 pinout, GBJ1504 application, or GBJ1504 equivalent, key selection factors include VRRM margin for line-voltage transients, thermal resistance (0.8°C/W junction-to-case), IFSM capability for inrush handling, and through-hole GBJ package compatibility with PCB mounting via #6 screw.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a common cathode/anode configuration to convert AC input into unidirectional DC output. Its standard recovery characteristic (non-fast, non-ultrafast) suits line-frequency (50/60Hz) applications where switching losses are secondary to conduction efficiency and surge robustness.
The device operates across –55°C to +150°C junction temperature range and delivers 15A average rectified current when mounted on a 300mm × 300mm × 1.6mm copper heatsink. Junction capacitance is 60pF at 1MHz and 4V reverse bias, confirming suitability for low-noise, low-RF-emission power front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands 400V repetitive reverse voltage, enabling use with 230VAC mains (including 10% overvoltage and safety margins) |
| IF(AV) | 15 A - Sustains 15A average DC output current with proper heatsinking, supporting mid-power industrial power supplies |
| VF @ 7.5A | 1.05 V - Low conduction loss per diode leg, minimizing power dissipation (≈7.9W total bridge loss at full load) |
| IR @ 25°C | 10 µA - Minimal reverse leakage ensures stable DC bus hold-up and low standby power in offline SMPS front-ends |
| IFSM | 240 A - Handles high-energy inrush surges during cold-start of transformers and capacitive-input filters |
| RθJC | 0.8 °C/W - Enables efficient heat transfer to external heatsink, critical for continuous operation at rated current |
| TJ Range | –55°C to +150°C - Supports deployment in harsh environments including factory automation enclosures and outdoor power converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay GBU15J | Same 400V VRRM, 15A IF(AV), but TO-220AC package with single mounting hole and higher RθJC (1.5°C/W) | Requires larger heatsink area or forced air for equivalent thermal performance; less suitable for screw-mounted PCBs | Select when existing layout uses TO-220 footprint and thermal budget permits higher junction rise |
| ON Semiconductor GBPC1504 | Identical 400V/15A rating and GBJ package, but 1.1V VF max (vs. 1.05V) and 20µA IR max (vs. 10µA) | Slightly higher conduction loss and leakage may affect efficiency-critical or low-power-holdup designs | Acceptable drop-in replacement where 50mV VF and 10µA IR margin are not design-critical |
Compared with GBU15J and GBPC1504, GBJ1504 offers superior thermal resistance (0.8°C/W), tighter leakage spec (10µA), and optimized mechanical interface for screw-mount PCBs - making it preferred for space- and thermally constrained industrial power stages.

FAQ
What is the maximum operating temperature for GBJ1504?
The GBJ1504 has a specified junction temperature range of –55°C to +150°C. Its thermal resistance is 0.8°C/W (junction-to-case), so sustained operation at 15A requires a heatsink capable of maintaining case temperature ≤105°C to stay within the 150°C TJ limit. Ambient derating curves are provided in DS21219 Figure 1.
Is GBJ1504 suitable for use in automotive applications?
GBJ1504 is not AEC-Q101 qualified and is not recommended for automotive powertrain or safety-critical systems. However, it may be used in non-safety automotive aftermarket accessories (e.g., cabin lighting controllers) where qualification is not mandated - subject to customer validation of thermal, vibration, and lifetime requirements.
How does the GBJ package differ from KBPC or WOB packages?
The GBJ package is a 4-pin, single-in-line (SIL) molded plastic housing with two AC inputs and ±DC outputs, designed for screw mounting. KBPC uses a larger rectangular base with integrated heatsink flange, while WOB is a smaller, lower-current 4-pin inline variant. GBJ offers better mechanical rigidity and higher IFSM than WOB, and simpler PCB integration than KBPC.
Can GBJ1504 replace GBJ1506 in a 600V design?
No - GBJ1504 has a 400V VRRM rating and must not be substituted for GBJ1506 (600V VRRM) in circuits exposed to ≥400V reverse stress. Doing so risks catastrophic failure during line transients or no-load conditions. Voltage ratings are not interchangeable; always match or exceed required VRRM with margin.
