KBJ604G

Overview

The KBJ604G is a single-phase standard recovery bridge rectifier manufactured by Diodes Incorporated. It provides an average rectified output current of 6.0 A and supports a peak repetitive reverse voltage of 400 V. The device features a maximum forward voltage of 1.0 V at 3.0 A and a peak reverse current of 5.0 µA at rated DC blocking voltage. It withstands a non-repetitive peak forward surge current of 170 A for an 8.3 ms half-sine wave. Operating temperatures range from -55 °C to +150 °C, and the component utilizes a KBJ through-hole package.

Feature Summary

• Glass passivated die construction ensures reliable operation under high-voltage conditions.
• High case dielectric strength of 2500 VRMS provides robust electrical isolation.
• Low reverse leakage current minimizes power loss during the blocking state.
• Surge overload rating up to 170 A peak protects against transient current spikes.

Applications

• Printed circuit board integration in general-purpose power supplies
• AC-to-DC conversion circuits requiring standard recovery characteristics
• Industrial electronics operating within specified thermal limits

Procurement Notes

Verify the specific part number KBJ604G against official Diodes Incorporated documentation to confirm technical specifications and compliance status. Ensure that procurement channels are authorized to prevent counterfeit components. Check for RoHS compliance and lead-free finish requirements relevant to your manufacturing standards before placing orders.

Selection Notes

Select the KBJ604G when a 400 V reverse voltage rating and 6.0 A continuous current capacity are required. Consider the KBJ series for applications needing a through-hole mounting style with a 94V-0 flammability rating. Evaluate thermal management needs as the current rating is defined at a case temperature of +110 °C.

Part Context

The KBJ604G belongs to the KBJ6005G-KBJ610G family of 6.0 A standard recovery bridge rectifiers. This series offers various voltage ratings ranging from 50 V to 1000 V while maintaining consistent current handling and physical dimensions. The KBJ package design facilitates easy mounting on printed circuit boards using #6 screws.

Replacement Considerations

Direct replacements must match the 6.0 A current rating, 400 V reverse voltage, and KBJ package form factor. Verify that alternative bridge rectifiers meet the same forward voltage and surge current specifications to ensure circuit compatibility without redesigning the PCB layout or thermal solution.
