KBJA1506-BP

Overview

The KBJA1506-BP is a single-phase glass passivated bridge rectifier manufactured by Micro Commercial Components (MCC). It provides an average forward current of 15 A at a case temperature of 100°C with a heatsink, and 3.2 A at 25°C ambient without a heatsink. The device features a maximum recurrent peak reverse voltage of 600 V, a maximum RMS voltage of 420 V, and a maximum DC blocking voltage of 600 V. Electrical characteristics include a maximum instantaneous forward voltage of 1.0 V at 7.5 A and 25°C, and a maximum DC reverse current of 150 μA at 125°C. The component supports a peak forward surge current of 220 A for an 8.3 ms half sine-wave pulse.

Feature Summary

• Glass passivation technology ensures stable electrical performance and reliability under varying thermal conditions.
• Epoxy casing meets UL 94 V-0 flammability rating for enhanced safety in enclosed applications.
• High surge forward current capability allows the device to withstand transient overcurrent events.

Applications

• AC-to-DC conversion in power supply circuits requiring 600 V isolation.
• Bridge rectification in industrial equipment operating within specified thermal limits.
• General-purpose rectification in consumer electronics utilizing the JB package form factor.

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors listed on the official website. Counterfeit components pose significant risks; unauthorized sources do not provide warranty coverage or traceability. Confirm that the ordering suffix '-BP' indicates RoHS compliance and lead-free finish as defined in the manufacturer's documentation before finalizing acquisition.

Selection Notes

Select this component when a 600 V peak reverse voltage rating is required for single-phase bridge rectification. Ensure the application design accommodates the 15 A continuous current rating only when using an appropriate heatsink to maintain case temperature at 100°C or below. Verify that the PCB layout supports the JB package dimensions and mounting torque specifications provided in the mechanical data section.

Part Context

This part belongs to the KBJA1506 through KBJA1510 series, which share identical mechanical dimensions and thermal characteristics but differ in voltage ratings. The KBJA1506 specifically denotes the 600 V variant within this family. All devices in this series utilize the JB package and offer comparable surge current capabilities and forward voltage profiles.

Replacement Considerations

Direct substitutes within the same voltage class include the KBJA1508 and KBJA1510, which share identical physical and thermal parameters but offer higher reverse voltage ratings of 800 V and 1000 V respectively. Cross-brand replacements must match the 15 A current rating, 600 V minimum reverse voltage, and JB package footprint to ensure compatibility.

FAQ
