KBL402G T0

Overview

The KBL402G T0 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a peak repetitive reverse voltage (Vrrm) of 100 V and an average forward rectified current (Io) of 4 A. The device utilizes standard silicon technology and is housed in a KBL through-hole package with four pins. Key electrical parameters include a maximum forward voltage (Vf) of 1.1 V at 4 A, a reverse leakage current (Ir) of 10 µA at 100 V, and a peak non-repetitive forward surge current (Ifsm) of 50 A. The operating junction temperature range spans from -55°C to +150°C.

Feature Summary

• Single-phase bridge rectifier configuration for AC to DC conversion
• Through-hole mounting via KBL package for robust mechanical stability
• Standard silicon construction suitable for general-purpose applications

Applications

• General-purpose power supply circuits
• DC power adapters and chargers
• Low-voltage rectification in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout and packaging details. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices as this part may have limited availability or be subject to change. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a 100 V rating and 4 A continuous current are required in a compact through-hole format. Compare Vf and Ir specifications against alternative brands to ensure compatibility with thermal management constraints. Verify that the KBL package dimensions fit within the designated PCB footprint and clearance requirements.

Part Context

This component 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 geometry. The KBL402G T0 specifically targets low-voltage applications requiring reliable rectification in standard industrial and consumer environments.

Replacement Considerations

Direct substitutes include other KBL402 variants from different manufacturers such as GeneSiC Semiconductor's KBL402G. Ensure replacement parts match the 100 V Vrrm, 4 A Io, and KBL package specifications. Verify equivalent thermal and electrical characteristics before integration.
