GBPC2506W

Overview

The onsemi GBPC2506W is a single-phase bridge rectifier from the GBPC25 series, rated for a maximum repetitive reverse voltage of 600 V and an average rectified forward current of 25 A at a case temperature of 55°C. It features a non-repetitive peak forward surge current capability of 300 A over an 8.3 ms half-sine-wave pulse. The device utilizes a GBPC-W package with wire leads and silver-plated terminals, offering a maximum forward voltage drop of 1.1 V at 12.5 A and a reverse leakage current of 5 µA at 25°C. Thermal resistance from junction to case is 1.5°C/W with a heatsink, supporting operation within a temperature range of -55°C to +150°C.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for efficient heat dissipation.
• Surge overload ratings support high transient currents up to 300 A.
• Provides isolated voltage from case to lead exceeding 2500 V.
• Terminals are silver-plated, ensuring solderability per MIL-STD-208.

Applications

• General-purpose power supply circuits requiring single-phase rectification.
• Industrial equipment utilizing resistive or inductive loads.
• Applications necessitating high surge current tolerance and robust thermal management.

Procurement Notes

Verify component authenticity by checking the marking code against official datasheet specifications. Confirm the GBPC-W suffix indicates the wire lead structure variant rather than standard pin termination. Ensure compliance with RoHS directives as these are Pb-Free devices. Validate that the specific lot matches the required UL certification number E258596 for safety standards.

Selection Notes

Select this component when a 600 V rating and 25 A continuous current capacity are required in a through-hole configuration. The GBPC-W package is suitable for applications where wire leads facilitate easier assembly compared to standard pin types. Consider the 1.5°C/W thermal resistance for heatsink design calculations to maintain junction temperatures within the specified limits under maximum load conditions.

Part Context

This part belongs to the GBPC 12, 15, 25, and 35 series of glass-passivated bridge rectifiers manufactured by onsemi. The series offers various voltage ratings from 50 V to 1000 V across different current capacities. The GBPC2506W specifically represents the 25 A current class with a 600 V blocking voltage, utilizing the W suffix to denote its unique wire lead packaging format distinct from the standard GBPC pin package.

Replacement Considerations

Direct substitutes include other GBPC2506 variants from different manufacturers such as SMC Diode Solutions (GBPC2506W) or Vishay (VS-GBPC2506A), provided terminal styles match the application requirements. Verify that alternative components meet the same 600 Vrrm, 25 A If(av), and 300 A Ifsm specifications to ensure functional equivalence.
