GBPC3501

Overview

The onsemi GBPC3501 is a single-phase bridge rectifier from the GBPC 12, 15, 25, 35 series. It features a maximum repetitive reverse voltage (VRRM) of 100 V and an average rectified forward current (IF(AV)) of 35 A at a case temperature of 55°C. The device supports a non-repetitive peak forward surge current (IFSM) of 400 A for an 8.3 ms half-sine wave. Electrical characteristics include a maximum forward voltage drop (VF) of 1.1 V at 17.5 A and a maximum reverse current (IR) of 5 µA at 25°C. Thermal resistance from junction to case is 1.5°C/W with a heatsink. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation.
• Terminals feature silver finish material suitable for soldering per MIL-STD-208.
• Isolated voltage from case to lead exceeds 2500 V.

Applications

• General-purpose AC to DC power supply conversion.
• Industrial equipment requiring high surge current capability.
• Battery charging circuits.

Procurement Notes

Verify the specific package type against project requirements, as the datasheet distinguishes between standard GBPC and wire-lead GBPC-W variants. Confirm that the selected part number matches the required voltage rating and mounting style. Ensure compliance with RoHS directives if applicable to the assembly process. Check for any discontinuation notices regarding this specific ordering suffix before finalizing procurement plans.

Selection Notes

Select the GBPC3501 when a 100 V reverse voltage rating and 35 A continuous current are required. Consider the 400 A surge rating for applications with potential inrush currents. Evaluate the thermal management strategy, as the 1.5°C/W junction-to-case rating assumes proper heatsinking. Compare against other series members like GBPC3502 or GBPC3504 if different voltage ratings better suit the circuit design.

Part Context

This component belongs to the GBPC 12, 15, 25, 35 series of glass-passivated bridge rectifiers manufactured by onsemi. The series offers various voltage ratings from 50 V to 1000 V while maintaining consistent current handling capabilities across the 35 A variant. The GBPC3501 specifically addresses lower voltage AC rectification needs within this robust package family.

Replacement Considerations

Direct replacements must match the 35 A current rating, 100 V reverse voltage, and GBPC package dimensions. Verify thermal resistance and surge current capabilities to ensure equivalent performance in the target application without derating issues.
