KBL402

Overview

The KBL402 is a single-phase glass passivated bridge rectifier manufactured by EIC Semiconductor Inc. It provides a maximum average forward current of 4.0 A and a peak reverse voltage rating of 200 V. The device features a low forward voltage drop of 1.05 V at 2 A and a maximum DC reverse current of 10 µA at 25 °C. It supports a peak forward surge current of 120 A under half-sine wave conditions. The component operates within a junction temperature range of -55 to +150 °C and utilizes a molded plastic case with UL94V-0 flame retardant epoxy.

Feature Summary

• Glass passivated chip construction for high reliability
• High current and surge current capability
• Low reverse leakage current and forward voltage drop
• Suitable for printed circuit board mounting

Applications

• Printed circuit board power supply circuits
• AC to DC conversion in general electronics
• Half-wave or full-wave rectification applications

Procurement Notes

Verify the manufacturer marking on the component body matches EIC Semiconductor Inc. specifications. Confirm the part number suffix corresponds to the 200 V rating variant. Ensure compliance with RoHS directives if lead-free versions are required for the specific assembly process. Check datasheet revisions for any updates to mechanical dimensions or electrical limits before finalizing procurement orders.

Selection Notes

Select the KBL402 when a 200 V peak reverse voltage rating is required for 4 A rectification tasks. Consider the thermal resistance of 21 °C/W for heat dissipation planning. Derate the forward current by 20% if used with capacitive loads. Ensure the operating ambient temperature remains within the specified range to maintain performance and longevity.

Part Context

This component belongs to the KBL400-KBL410 series of glass passivated bridge rectifiers. The series offers varying peak reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 4.0 A average forward current rating. All variants share identical mechanical dimensions and package styles, facilitating design flexibility across different voltage requirements.

Replacement Considerations

Compatible substitutes include the KBL402G from Diodes Incorporated and the KBL402 from Panjit International. Verify that replacement parts match the 200 V PRV, 4.0 A IF(AV), and KBL package dimensions. Ensure the alternative components offer equivalent thermal resistance and surge current capabilities.
