Product details
Overview
GBPC2502 from Diodes Incorporated is a 25A glass passivated single-phase bridge rectifier with 200V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 12.5A per diode, 300A non-repetitive surge rating, and metal-base thermal design for heatsink mounting. It delivers high-efficiency AC-to-DC conversion in industrial power supplies and motor drive front-ends.
For engineers reviewing the GBPC2502 datasheet, GBPC2502 pinout, GBPC2502 application, or GBPC2502 equivalent, key selection factors include its 200V blocking capability, 25A average output current at TC = 60°C, case-isolation voltage of 1500V, and through-hole #10 screw mounting configuration for high-reliability thermal management.
Technical Context
This bridge rectifier integrates four silicon diodes in a single molded plastic package with internal heatsink, configured as a full-wave single-phase topology. Its glass passivated die construction ensures low reverse leakage (5.0 µA at 25°C) and stable operation across –65°C to +150°C junction temperature range.
The device operates under standard 60Hz resistive/inductive loads without derating, but requires 20% current reduction for capacitive loads. Thermal resistance is specified at 1.3°C/W per leg when mounted on a heatsink, enabling sustained 25A conduction with appropriate thermal design.
Key Specifications

| IO @ TC=60°C | 25 A - Continuous average DC output current with case temperature maintained at 60°C |
| VFM @ IF=12.5A | 1.1 V - Forward voltage drop per diode leg, defining conduction loss at half-rated current |
| IFSM | 300 A - Single half-sine surge current tolerance (8.3ms), critical for inrush handling |
| RθJC | 1.3 °C/W - Junction-to-case thermal resistance per diode leg, used to calculate heatsink requirements |
| Isolation Voltage | 1500 V - Dielectric strength between case and terminals, supporting safety-critical isolation |
| CT @ 1MHz | 300 pF - Total junction capacitance per diode, influencing high-frequency noise and EMI behavior |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBJ2502 | Same 25A/200V rating but in GBJ package (single-in-line, PCB mount); no metal baseplate; RθJC = 2.0°C/W | Lacks screw-mount heatsink interface; suited for lower-power density PCB layouts where forced-air cooling applies | Select GBJ2502 only if mechanical mounting constraints prohibit GBPC-style chassis attachment. |
| KBPC2502 | Identical electrical specs and GBPC package; manufactured by ON Semiconductor; same pinout and thermal profile | No functional difference; qualifies as second-source part with identical qualification and test flow | Choose KBPC2502 for supply chain diversification without redesign or thermal revalidation. |
Compared with GBJ2502, GBPC2502 offers superior thermal performance via metal-base mounting, while KBPC2502 provides identical functionality with alternate sourcing-making GBPC2502 optimal for thermally demanding, chassis-mounted industrial applications.

FAQ
What is the maximum allowable case temperature for continuous operation of GBPC2502?
The datasheet specifies a maximum case temperature (TC) of 60°C for rated 25A average output current. Exceeding this temperature requires linear derating per Figure 1, reaching zero current at 150°C. Sustained operation above 60°C without thermal recalculations risks premature failure due to junction overheating.
Can GBPC2502 be used with capacitive loads without modification?
No. The datasheet explicitly requires a 20% reduction in average output current when driving capacitive loads. This derating compensates for higher peak currents caused by capacitor charging transients, preventing overstress of the diode junctions and ensuring reliable long-term operation.
Is GBPC2502 RoHS compliant and lead-free?
Yes. GBPC2502 features a lead-free finish and complies with RoHS Directive 2002/95/EC (as revised March 2003), including exemptions for glass and high-temperature solder per EU Directive Annex Notes 5 and 7. Full compliance documentation is available in Diodes' AP02008 packaging specification.
Does GBPC2502 require external snubber circuits in typical 60Hz applications?
Not for standard resistive or inductive loads at 60Hz. The device's 300pF total capacitance and glass passivated construction provide inherent noise suppression. Snubbers are only recommended in high-dI/dt switching environments (e.g., SCR-controlled phase-angle circuits) or when EMI testing reveals conducted emissions exceed limits.
