KBPC15005

Overview

The Good-Ark Semiconductor KBPC15005 is a glass passivated single-phase bridge rectifier from the KBPC15 series. It features a maximum repetitive peak reverse voltage (VRRM) of 50 V and an average rectified output current (IO) of 15 A at 60 Hz with a heatsink at Tc=55°C. The maximum instantaneous forward voltage drop per diode is 1.1 V at IFM=7.5 A, while the maximum DC reverse current is 10 µA at rated blocking voltage. The device supports a surge non-repetitive forward current of 300 A for a half-sine wave cycle at TA=25°C. It operates within a junction temperature range of -55°C to +150°C and includes electrically isolated terminals with a dielectric strength of 1800 V.

Feature Summary

• Glass passivated chip junctions provide stable electrical characteristics and protection against voltage transients.
• Electrically isolated metal base allows direct mounting to heat sinks without external insulators, facilitating efficient thermal dissipation.
• Low forward voltage drop contributes to high efficiency in power conversion applications.
• High surge current capability ensures reliability during transient overload conditions.

Applications

• AC-DC power supply circuits requiring 50 V isolation
• Battery charging systems operating at low voltages
• General purpose rectification in industrial equipment

Procurement Notes

Verify that the component matches the specific voltage rating required by the circuit design, as the KBPC15 series spans multiple voltage options. Confirm the package type corresponds to the PCB footprint, noting that wire lead variants carry a 'W' suffix. Ensure compliance with RoHS directives if environmental regulations apply to the assembly process. Cross-reference datasheet thermal resistance values with actual heatsinking requirements to maintain safe junction temperatures under load.

Selection Notes

Select this component when a 15 A continuous current capacity and 50 V reverse voltage rating are necessary. Consider the physical dimensions and terminal spacing for PCB layout compatibility. Evaluate thermal management needs based on the specified case temperature limits. Compare alternative packages if higher current ratings or different voltage thresholds are required for the target application.
