GBPC1202W

Overview

The onsemi GBPC1202W is a single-phase glass-passivated bridge rectifier belonging to the GBPC12 series. It features an average forward current of 12 A at a case temperature of 55°C and a maximum repetitive reverse voltage of 200 V. The device supports a non-repetitive peak forward surge current of 300 A for 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 current of 5.0 µA at rated voltage and 25°C. The component utilizes a GBPC-W package with wire leads, operates within a junction temperature range of -55°C to +150°C, and provides over 2500 V isolation between the case and leads.

Feature Summary

• Integrally molded heat sink designed for very low thermal resistance to maximize heat dissipation capabilities.
• Surge overload ratings capable of handling high transient currents ranging from 300 A to 400 A depending on the series.
• Provides isolated voltage protection from case to lead exceeding 2500 V for enhanced safety.
• Terminals feature a silver finish suitable for soldering per MIL-STD-202 Method 208 standards.

Applications

• Power supply units requiring single-phase rectification
• Adapters and chargers utilizing standard bridge configurations
• General-purpose DC power conversion circuits

Procurement Notes

Verify component authenticity by checking the marking code against official datasheet specifications. Confirm the presence of the 'W' suffix indicates the wire lead structure variant rather than a functional change. Ensure compliance with RoHS directives as these are lead-free devices. Review the discontinuation status in ordering information tables before finalizing procurement plans.

Selection Notes

Select this component based on the required 200 V reverse voltage rating and 12 A continuous current capacity. Consider the GBPC-W package dimensions and wire lead configuration for PCB layout compatibility. Evaluate thermal management requirements given the 1.5°C/W junction-to-case thermal resistance. Verify that the operating environment stays within the specified -55°C to +150°C temperature range.

Part Context

This part belongs to the GBPC12, 15, 25, and 35 series of glass-passivated bridge rectifiers manufactured by onsemi.
