GBPC3501W

Overview

The onsemi GBPC3501W 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 junction 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 wire lead structures.
• Isolated voltage from case to lead exceeds 2500 V.
• UL certified under UL #E258596.

Applications

• General-purpose AC to DC power supply conversion.
• Industrial equipment requiring robust single-phase rectification.
• Applications necessitating high surge overload ratings up to 400 A.

Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the required wire lead structure rather than standard pin leads. Confirm that the package marking matches the part number exactly. Ensure compliance with RoHS directives as these are Pb-Free devices. Check for any discontinuation notices or recommended new design alternatives if sourcing for long-term production.

Selection Notes

Select this component when a 100 V rating and 35 A continuous current capacity are required in a through-hole GBPC-W package. Consider the 1.5°C/W thermal resistance for heatsinking requirements. Verify that the 400 A surge capability meets transient load demands. Compare against other series members like GBPC3502W or GBPC3504W if higher voltage ratings are needed.

Part Context

This part 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 and thermal characteristics for the 35 A variant. The GBPC3501W specifically addresses low-voltage, high-current applications within this standardized family.

Replacement Considerations

Direct substitutes may include other manufacturers' GBPC3501 equivalents. Verify pinout compatibility and thermal performance. Ensure the replacement maintains the same silver terminal finish if MIL-STD solderability is required. Cross-reference datasheets for exact VF and IR limits.
