Product details
Overview
GBJ1504-F 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 front-end power supplies for industrial motor drives.
For engineers reviewing the GBJ1504-F datasheet, GBJ1504-F pinout, GBJ1504-F application, or GBJ1504-F equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (0.8°C/W junction-to-case), IFSM capability for inrush handling, and through-hole mounting compatibility with #6 screw fastening.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a common GBJ molded plastic package. Its standard recovery characteristic (non-fast, non-ultrafast) suits general-purpose line-frequency rectification where switching losses are secondary to conduction efficiency and ruggedness.
The device operates across –55°C to +150°C junction temperature range and delivers 15A average output current when mounted on a 300mm × 300mm × 1.6mm copper heatsink. Thermal resistance of 0.8°C/W enables predictable junction temperature rise under sustained load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands 400V repetitive reverse voltage, suitable for 230VAC mains with 1.8× safety margin |
| IF(AV) | 15 A - Sustained DC output current capability with heatsink cooling |
| VF @ 7.5A | 1.05 V - Total forward drop across two series diodes in conduction path |
| IR @ 25°C | 10 µA - Low reverse leakage preserves efficiency in high-impedance hold-up stages |
| IFSM | 240 A - Handles 8.3ms half-sine surge, sufficient for capacitor-input filter inrush |
| RθJC | 0.8 °C/W - Enables thermal design with measurable junction temperature rise per watt dissipated |
| TJ Range | –55°C to +150°C - Supports operation in sealed industrial enclosures without active cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU15J-E3/54 (Vishay) | Same GBU package, 400V VRRM, but 1.1V VF @ 7.5A and 0.95°C/W RθJC | Slightly higher conduction loss and thermal resistance; requires larger heatsink area | Acceptable where footprint compatibility is critical and thermal headroom exists |
| KBU1504 (ON Semiconductor) | Same VRRM and IF(AV), but 1.2V VF and 1.0°C/W RθJC; no UL recognition | Higher power dissipation and no UL file - limits use in certified end equipment | Only suitable for non-certified internal subsystems with ample thermal margin |
Compared with GBU15J-E3/54 and KBU1504, GBJ1504-F offers lower VF and superior thermal performance plus UL recognition - making it preferred for safety-certified industrial power supplies where efficiency and regulatory compliance are jointly required.

FAQ
What is the maximum operating temperature for GBJ1504-F?
The GBJ1504-F has a specified junction temperature range of –55°C to +150°C. Its storage temperature range matches this span. Operation at +150°C requires thermal design ensuring junction temperature does not exceed this limit under worst-case load and ambient conditions, using the 0.8°C/W RθJC value and measured power dissipation.
Is GBJ1504-F RoHS compliant and lead-free?
Yes, GBJ1504-F features lead-free tin plating and complies with EU RoHS Directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. All applicable RoHS exemptions are applied, and the device is marked "Lead-Free Finish" in Diodes' official documentation and packaging.
Can GBJ1504-F be used in automotive applications?
GBJ1504-F is not qualified to AEC-Q101 and is not manufactured in an IATF 16949-certified facility per Diodes' public product definitions. It is intended for industrial and commercial applications. For automotive use, contact Diodes directly to discuss qualified alternatives such as the AEC-Q101-compliant GBJ1504Q part.
What is the mounting torque specification for GBJ1504-F?
The GBJ1504-F datasheet specifies a maximum mounting torque of 5.0 in-lbs for the #6 screw used in through-hole mechanical mounting. Exceeding this torque may damage the molded plastic body or compromise internal die attachment integrity.
