Product details
Overview
GBJ2504-F from Diodes Incorporated is a 25A standard recovery bridge rectifier in GBJ package, rated for 400V peak repetitive reverse voltage (VRRM), 1.05V max forward voltage at 12.5A, and 350A surge current capability; used in AC/DC front-end power conversion for industrial power supplies and motor drive input stages.
For engineers reviewing the GBJ2504-F datasheet, GBJ2504-F pinout, GBJ2504-F application, or GBJ2504-F equivalent, key selection criteria include VRRM rating, IF(AV) derating with heatsink, thermal resistance (RθJC = 1.0°C/W), and UL recognition for safety-critical board-level designs.
Technical Context
This single-phase full-wave bridge rectifier integrates four standard recovery diodes in a monolithic GBJ molded plastic package with through-hole mounting. It delivers 25A average output current when mounted on a 250mm × 250mm × 20mm aluminum heatsink, with junction temperature operating range from –55°C to +150°C.
The device features glass-passivated die construction, 2500VRMS case dielectric strength, and low reverse leakage (≤10µA at 25°C, ≤500µA at 125°C), supporting reliable operation in high-noise industrial environments where voltage transients and thermal cycling are common.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage per diode leg; defines safe AC input voltage ceiling before breakdown. |
| IF(AV) | 25 A - Average rectified output current with heatsink; requires thermal management to sustain continuous load. |
| VF Max | 1.05 V @ 12.5A - Forward voltage drop determines conduction loss and heat generation at rated half-load. |
| IFSM | 350 A - Peak surge current handling for 8.3ms half-sine; supports inrush current during cold-start of capacitive-input supplies. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables precise heatsink sizing using measured case temperature. |
| IR Max | 10 µA @ 25°C - Reverse leakage current; critical for low-power standby circuits and high-impedance sensing nodes. |
Pinout & Package
Package: GBJ - Molded plastic, UL 94V-0 rated, lead-free tin-plated leads, 6.6g weight, designed for #6 screw mounting with 5.0 in-lbs max torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| – (Cathode Common) | DC Negative Output | Full-wave rectified negative DC output; ties internally to cathode ends of two diodes. |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Industrial Power Supply Input Stage | Motor Drive AC Input Rectification |
|---|---|
Use Scenario: Converts 230VAC mains or transformer-derived AC to unregulated DC bus in DIN-rail mounted PSUs. IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing primary DC rail with minimal conduction loss and robust surge tolerance. Use Value: 350A IFSM withstands capacitor charging surges; 1.05V VF limits power dissipation to ≤13W at 12.5A, easing heatsink design. | Use Scenario: Rectifies AC supply feeding three-phase inverter front-end in HVAC blower or pump drives. IC Role / Device Role / Timing Role: Single-phase bridge supplying DC link for auxiliary control power or braking resistor interface. Use Value: 400V VRRM accommodates 230VAC ±10% with margin; UL recognition simplifies system-level safety documentation. |
| LED Streetlight Driver Input | Welding Equipment Primary Rectification |
Use Scenario: AC/DC conversion stage in outdoor-rated LED drivers exposed to wide ambient temperature swings. IC Role / Device Role / Timing Role: Input rectifier operating continuously at elevated ambient (up to +85°C) with thermal cycling. Use Value: –55°C to +150°C TJ range ensures functionality across outdoor extremes; low IR minimizes standby loss. | Use Scenario: High-current rectification in portable arc welding power sources with intermittent duty cycles. IC Role / Device Role / Timing Role: Handles repetitive 350A surge pulses during weld initiation without thermal runaway. Use Value: 510 A²s I²t rating provides fusing protection margin; RθJC = 1.0°C/W enables rapid transient thermal response. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU8K (ON Semiconductor) | Same 400V VRRM, 8A IF(AV), smaller GBU package, higher VF (1.1V) | Limited to lower-current designs; not suitable for 25A continuous loads without parallel devices | Select only if space-constrained and thermal budget allows higher conduction loss |
| KBP204 (Comchip) | 400V VRRM, 2A IF(AV), KBP package, VF = 1.1V, no UL recognition | Restricted to signal-level or low-power auxiliary rails; lacks safety certification for main power paths | Use only for non-safety-critical, low-current bias supplies where certification is not required |
Compared with GBU8K and KBP204, the GBJ2504-F uniquely supports 25A continuous current with UL recognition and 2500VRMS isolation-making it the only viable option for certified, high-current industrial AC/DC front-ends without paralleling or derating.

FAQ
What is the maximum heatsink temperature allowed for continuous 25A operation?
The GBJ2504-F sustains 25A average current when mounted on a 250mm × 250mm × 20mm aluminum plate heatsink with case temperature ≤85°C. At TJ = +150°C (max), RθJC = 1.0°C/W implies a 65°C allowable temperature rise from case to junction-so heatsink design must ensure case stays ≤85°C under worst-case ambient and airflow conditions.
Is GBJ2504-F qualified for automotive applications?
No-GBJ2504-F is not AEC-Q101 qualified. While Diodes offers automotive-grade variants (e.g., GBJ2504Q), this part is intended for industrial and commercial use. For automotive systems, contact Diodes directly to obtain PPAP-capable, IATF 16949-manufactured alternatives with full change control and qualification data.
Can GBJ2504-F be used without a heatsink?
Only for short-duration, low-duty-cycle operation. At 25A with no heatsink, junction temperature exceeds 150°C within seconds due to RθJC = 1.0°C/W and ~13W power dissipation. Continuous operation requires the specified aluminum plate heatsink or equivalent thermal solution to maintain TJ ≤150°C.
Does the GBJ2504-F have polarity marking on the package?
Yes-polarity is molded directly onto the plastic body: the "+" and "–" symbols are embossed adjacent to their respective DC output terminals, and AC input terminals are marked "~" or labeled AC1/AC2 per Diodes' package outline drawing. This eliminates ambiguity during PCB assembly and field service replacement.
