GBPC1201

Overview

The onsemi GBPC1201 is a single-phase glass-passivated bridge rectifier belonging to the GBPC12 series. It features an integrally molded heat sink for efficient thermal management and operates within a junction temperature range of -55°C to +150°C. The device supports a maximum repetitive reverse voltage (VRRM) of 100 V and delivers an average rectified forward current (IF(AV)) of 12 A at a case temperature of 55°C. It withstands a non-repetitive peak forward surge current (IFSM) of 300 A over an 8.3 ms half-sine wave. Electrical characteristics include a maximum forward voltage drop of 1.1 V at 6.0 A and a maximum reverse leakage current of 5.0 µA at rated voltage and 25°C.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation.
• Glass passivation ensures stable electrical performance and reliability under various operating conditions.
• Terminals are finished with nickel plating for the standard GBPC package, ensuring durability.

Applications

• Power supply units requiring high current rectification.
• Battery chargers utilizing single-phase AC input.
• DC power conversion circuits in industrial equipment.

Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number GBPC1201 corresponds to the bulk-packed GBPC package variant. If wire leads are required, the GBPC1201W suffix must be used. Confirm that the procurement channel sources from authorized distributors to ensure component authenticity and compliance with RoHS standards as specified by the manufacturer.

Selection Notes

Select this component based on the 100 V reverse voltage rating and 12 A continuous current capability. Ensure the application's thermal environment allows for operation within the specified case temperature limits or requires adequate heatsinking given the 1.5°C/W junction-to-case thermal resistance. Verify that the surge current requirements do not exceed the 300 A IFSM limit during startup or fault conditions.

Part Context

This device is part of the broader GBPC 12, 15, 25, and 35 series published by onsemi. The series shares common mechanical dimensions (Case 160AD) and packaging styles, differing primarily in current ratings and voltage capabilities. The GBPC1201 specifically represents the 12 A / 100 V configuration within this family of high-current silicon bridge rectifiers.

Replacement Considerations

Compatible alternatives include the GBPC1201W for identical specifications with wire leads. Other manufacturers producing equivalent 12 A / 100 V bridge rectifiers in the GBPC form factor may serve as substitutes, provided their thermal and electrical ratings meet or exceed the original specifications.

FAQ

What is the maximum repetitive reverse voltage for the GBPC1201?

The maximum repetitive reverse voltage (VRRM) for the GBPC1201 is 100 V.

How does the GBPC1201 differ from the GBPC1201W?

The primary difference is the terminal structure; the GBPC1201 uses solder pins for through-hole mounting, while the GBPC1201W features a wire lead structure.

What is the thermal resistance from junction to case?

The thermal resistance from junction to case (RθJC) is 1.5°C/W when mounted with a heatsink.
