KBL401G T0G

Overview

The KBL401G T0G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes glass passivated junctions for reliable performance and is housed in a KBL through-hole package with four pins. The device supports a maximum average forward rectified current of 4 A and offers a maximum repetitive peak reverse voltage of 50 V. Key electrical characteristics include a peak forward surge current rating of 150 A, a typical thermal resistance from junction to lead of 2.4 °C/W, and a maximum instantaneous forward voltage of 1.0 V at 2 A. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junction construction
• Halogen-free compliant design
• UL recognized file E-326243

Applications

• Printed circuit board mounting applications
• General purpose AC to DC rectification
• Power supply circuits

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm packaging details. The 'T0' code indicates tray packing, while 'G' denotes halogen-free green compound. Confirm RoHS compliance status and date codes directly with the manufacturer or authorized distributors before finalizing procurement orders.

Selection Notes

Select this component when a 50 V reverse voltage rating and 4 A continuous current are required in a standard KBL footprint. Ensure the application environment stays within the specified -55°C to +150°C operating junction temperature range. Verify that the expected surge currents do not exceed the 150 A limit defined in the absolute maximum ratings.

Part Context

This part belongs to the KBL401G through KBL407G series of glass passivated bridge rectifiers. The series covers voltage ratings from 50 V to 1000 V, all sharing the same 4 A current capacity and KBL package style. The KBL401G specifically represents the lowest voltage option in this lineup, designed for low-voltage AC conversion tasks.

Replacement Considerations

Compatible replacements must match the 4 A current rating, 50 V minimum reverse voltage, and KBL package dimensions. Verify that substitute components also feature glass passivation and meet the same thermal resistance specifications.
