Product details
Overview
GBJ2502-F from Diodes Incorporated is a 25A standard recovery bridge rectifier in GBJ package, rated for 200V peak repetitive reverse voltage (VRRM), 1.05V max forward voltage at 12.5A, and 350A peak surge current. It features glass-passivated die construction, 2500VRMS case dielectric strength, and is designed for AC-to-DC conversion in industrial power supplies and motor control circuits.
For engineers reviewing the GBJ2502-F datasheet, GBJ2502-F pinout, GBJ2502-F application, or GBJ2502-F equivalent, key selection criteria include VRRM rating, thermal resistance (1.0°C/W junction-to-case), surge capability (350A), reverse leakage (10µA @ 25°C), and through-hole mounting compatibility with #6 screw hardware.
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/soft recovery) suits line-frequency applications where switching losses are secondary to conduction efficiency and ruggedness.
The device operates across –55°C to +150°C junction temperature range and delivers 25A average rectified current when mounted on a specified 250mm × 250mm × 20mm aluminum heatsink. Thermal resistance of 1.0°C/W enables predictable junction temperature rise under sustained load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage the bridge withstands without breakdown; defines safe AC input voltage ceiling (e.g., ≤141V RMS). |
| IF(AV) | 25 A - Average DC output current capability with heatsink; determines continuous power handling in linearly loaded supplies. |
| VF Max | 1.05 V @ 12.5A - Forward voltage drop per diode path; directly impacts conduction loss (≈2.1W total at 12.5A). |
| IFSM | 350 A - Peak non-repetitive surge current tolerance; supports inrush current during cold-start of transformer-fed supplies. |
| RθJC | 1.0 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing for target TJ ≤150°C under steady-state load. |
| IR Max | 10 µA @ 25°C - Reverse leakage current per bridge leg; ensures minimal standby power loss in off-state conditions. |
| VB | 200 V - Breakdown voltage at IR = 10µA; confirms margin between operating VR and hard breakdown limit. |
Pinout & Package
Package: GBJ - Molded plastic, UL 94V-0 rated, through-hole mount with #6 screw hole, 6.6g mass, lead-free tin-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC Terminal 1 | One AC input node; connects to live/phase side of transformer secondary or AC line. |
| AC2 | Input AC Terminal 2 | Second AC input node; completes full-wave bridge input path with AC1. |
| + (Anode Common) | Positive DC Output | Full-wave rectified positive output node; feeds bulk capacitor or downstream regulator. |
| – (Cathode Common) | Negative DC Output / Return | Full-wave rectified negative return path; serves as system ground reference point. |

Applications
| Industrial Power Supplies | Motor Drive Front-Ends |
|---|---|
Use Scenario: AC mains-fed linear or phase-controlled power supplies delivering 20–30A DC output. IC Role / Device Role / Timing Role: Primary AC-to-DC conversion stage; provides unregulated DC bus for regulators or thyristor controllers. Use Value: 25A IF(AV) and 350A IFSM support high-current transformer secondaries without parallel devices. | Use Scenario: Rectification of AC supply feeding DC link capacitors in 3-phase inverter drives (single-phase input variant). IC Role / Device Role / Timing Role: Input-stage bridge rectifier converting single-phase utility power to stable DC bus voltage. Use Value: 200V VRRM accommodates 120/230VAC systems with safety margin; 1.0°C/W RθJC simplifies heatsink design for continuous operation. |
| Welding Equipment Power Stages | UPS Input Rectifiers |
Use Scenario: High-current DC power generation in portable or benchtop arc welding units. IC Role / Device Role / Timing Role: Main rectifier delivering pulsed DC output to welding transformer primary or inverter stage. Use Value: Surge rating of 350A handles intermittent high-current weld pulses without thermal runaway. | Use Scenario: Online or line-interactive UPS systems requiring robust input rectification and battery charging circuitry. IC Role / Device Role / Timing Role: Bidirectional energy path component-rectifies AC input and supports reverse-current battery charging mode. Use Value: Low IR (10µA) minimizes self-discharge during battery backup; UL recognition supports safety-critical backup infrastructure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU252 | Same 25A/200V rating, but GBU package (lower profile, no mounting hole); RθJC = 1.5°C/W. | Limited to PCB space-constrained designs without mechanical mounting requirement. | Select when board height is critical and heatsinking relies on copper area rather than external heatsink. |
| KBPC2502 | 25A/200V, but epoxy-insulated metal case; higher IFSM (400A), RθJC = 0.8°C/W. | Better suited for high-surge, high-reliability industrial equipment with metal chassis grounding. | Prefer when enhanced surge immunity and lower thermal resistance justify higher cost and larger footprint. |
Compared with GBU252 and KBPC2502, the GBJ2502-F uniquely combines screw-mount mechanical stability, UL recognition, and balanced thermal performance-making it optimal for field-serviceable industrial power modules where mounting torque (5.0 in-lbs) and traceable sourcing are required.

FAQ
What is the maximum heatsink temperature rise for GBJ2502-F at 25A DC output?
At 25A average output current and ambient temperature of 25°C, with a 250mm × 250mm × 20mm aluminum heatsink, the junction temperature rise is calculated as ΔTJ = IF² × RθJC × RθCS + RθSA. Given RθJC = 1.0°C/W and typical RθCS + RθSA ≈ 0.5°C/W, total thermal resistance is ~1.5°C/W, resulting in ~94°C rise above ambient-keeping TJ at ~119°C, well within the –55°C to +150°C operating range.
Can GBJ2502-F be used in automotive applications?
GBJ2502-F is not AEC-Q101 qualified and lacks automotive-specific change control, PPAP documentation, or IATF 16949 manufacturing certification. While its –55°C to +150°C operating range overlaps automotive requirements, Diodes explicitly states that automotive use requires contacting their representative for qualified alternatives-so this part is intended for industrial, commercial, and appliance applications only.
Is the GBJ2502-F RoHS 3 compliant and halogen-free?
Yes. GBJ2502-F meets EU Directive 2015/863/EU (RoHS 3), including all applicable exemptions. Diodes confirms it is lead-free and complies with their "Green" definition-meaning it contains <900 ppm bromine and <900 ppm antimony, and is fully halogen-free per their published specifications.
What is the recommended mounting torque for the GBJ2502-F screw hole?
The datasheet specifies a maximum mounting torque of 5.0 in-lbs for the integrated #6 screw hole. Exceeding this value risks cracking the molded plastic package or deforming internal wire bonds. Use a calibrated torque screwdriver and avoid thread-locking compounds unless validated for UL-compliant assembly per Diodes' application guidance.
