GBPC50005M

Overview

The GBPC50005M is a single-phase standard bridge rectifier from the Taiwan Semiconductor GBPC40, 50 Series. It features an average forward current (IF) of 50 A and a repetitive peak reverse voltage (VRRM) of 50 V. The device supports a peak forward surge current (IFSM) of 400 A for 8.3 ms half-sine waves. Electrical characteristics include a maximum forward voltage (VF) of 1.1 V at 25 A and a maximum reverse leakage current (IR) of 10 µA at rated VR. The junction-to-case thermal resistance is typically 1.5 °C/W. Operating temperatures range from -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junctions provide robust protection against mechanical stress and environmental factors.
• Integrally molded heatsink design ensures low thermal resistance for efficient heat dissipation.
• Universal four-way terminal configuration allows snap-on, wrap-around, solder, or PCB mounting options.

Applications

• Switching mode power supplies (SMPS)
• AC to DC converter circuits

Procurement Notes

Verify the specific part number suffix against official datasheets to confirm package type and electrical ratings. Ensure compliance with RoHS directives and UL recognition requirements for the intended application environment. Confirm mounting torque specifications do not exceed 20 in-lbs during assembly to prevent mechanical damage.

Selection Notes

Select this component based on the required 50 A continuous current and 50 V blocking voltage. Consider the 400 A surge capability for transient load conditions. Evaluate the thermal management needs relative to the 1.5 °C/W junction-to-case resistance. Verify that the operating temperature range meets system requirements.

Part Context

This component belongs to the GBPC40, 50 Series manufactured by Taiwan Semiconductor Corporation. The series includes variants with different current ratings (40 A or 50 A) and voltage ratings (50 V to 1000 V). The GBPC50005M specifically denotes the 50 A, 50 V variant within this standardized product line.

Replacement Considerations

Compatible substitutes include other GBPC series bridge rectifiers with matching 50 A current and 50 V voltage ratings. Ensure the replacement maintains similar thermal resistance and physical dimensions for direct board integration. Verify equivalent surge current capabilities and reverse leakage characteristics.
