SA150AHB0G Equivalent & Substitute Parts

Part Overview

The SA150AHB0G is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for transient overvoltage protection in electronic circuits. This component features a 150V reverse standoff voltage with a 243V maximum clamping voltage and 2.1A peak pulse current capability. The device is housed in a DO-204AC (DO-15) axial through-hole package and is qualified to AEC-Q101 automotive standards.

The SA150AHB0G is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring identical electrical and mechanical specifications.
