KBL401G T0

Overview

The KBL401G T0 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes the KBL through-hole package with four pins. The device supports a peak repetitive reverse voltage (Vrrm) of 50 V and an average forward rectified current (Io) of 4 A. Key electrical parameters include a maximum non-repetitive peak forward surge current (Ifsm) of 150 A, a peak forward voltage (Vf) of 1.1 V at 4 A, and a maximum reverse leakage current (Ir) of 10 µA. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Standard recovery rectification technology for general-purpose applications
• Through-hole mounting configuration in a compact KBL plastic package
• High surge current capability for robust circuit protection

Applications

• AC-DC power supply circuits
• Battery charging systems
• General-purpose rectification in low-voltage electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout and material compliance. Ensure the component matches the required voltage and current ratings for the target design. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component for designs requiring 50 V reverse voltage and 4 A continuous current in a through-hole format. Compare the KBL package dimensions against PCB layout constraints. Evaluate thermal management requirements based on the 150°C maximum junction temperature rating and expected ambient conditions.

Part Context

This part belongs to the KBL4 series of single-phase bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent current handling and package dimensions. The KBL401G variant specifically addresses low-voltage applications within this standardized product line.

Replacement Considerations

Direct replacements must match the 4 A current rating, 50 V voltage rating, and KBL package footprint. Verify that substitute components meet the same Vf and Ir specifications to ensure circuit performance compatibility.
