GBPC15005

Overview

The onsemi GBPC15005 is a single-phase bridge rectifier from the GBPC 12, 15, 25, and 35 series. It features an average rectified forward current (IF(AV)) of 15 A at a case temperature of 55°C and a maximum repetitive reverse voltage (VRRM) of 50 V. The device has a non-repetitive peak forward surge current (IFSM) rating of 300 A for an 8.3 ms half-sine-wave pulse. Electrical characteristics include a maximum forward voltage drop (VF) of 1.1 V at 7.5 A and a maximum reverse current (IR) of 5.0 µA at rated VR and 25°C. Thermal resistance from junction to case is 1.5°C/W with a heatsink, and power dissipation is rated at 83.3 W.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation.
• Glass passivated chip junctions ensure high reliability and stable performance.
• Terminals are available in silver finish for solderability or nickel finish for standard mounting.
• UL certified under file number E258596.

Applications

• General purpose AC to DC conversion in power supplies.
• Battery charging circuits requiring robust surge handling.
• Industrial equipment power stages operating within specified thermal limits.

Procurement Notes

Verify the specific package variant required for the application. The standard GBPC package utilizes nickel terminals, while the GBPC-W suffix indicates a wire lead structure with silver-plated terminals suitable for specific soldering processes. Confirm availability as some related part numbers in the series may be discontinued. Ensure compliance with RoHS directives as these devices are manufactured as lead-free products.

Selection Notes

Select this component when a 15 A continuous current rating and 50 V blocking capability are required. The GBPC15005 is suitable for applications demanding high surge tolerance up to 300 A. Consider the thermal environment carefully; derating curves must be consulted if the case temperature exceeds 55°C. For through-hole PCB mounting without screw terminals, verify that the standard package dimensions fit the layout constraints.

Part Context

This component belongs to the GBPC series of glass-passivated bridge rectifiers manufactured by onsemi. The series includes variants with different current ratings (12 A, 15 A, 25 A, 35 A) and voltage ratings (50 V to 1000 V). The GBPC15005 specifically represents the 15 A, 50 V configuration within this widely used industrial rectifier family.

Replacement Considerations

Direct substitutes within the same series include other GBPC15xx parts with higher voltage ratings, such as GBPC1501 (100 V) or GBPC1502 (200 V), provided the circuit voltage does not exceed their limits. Cross-manufacturer equivalents in the GBPC form factor should be verified for matching IF(AV), VRRM, and thermal resistance specifications.
