SA30AHB0G Equivalent & Substitute Parts

Part Overview

The SA30AHB0G is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for through-hole mounting in DO-204AC (DO-15) axial package configuration. This component provides transient voltage suppression with a 30V reverse standoff voltage and 64.3V maximum clamping voltage at peak pulse current of 10.8A. The part is classified as Automotive grade with AEC-Q101 qualification and operates across the temperature range of -55°C to 175°C (TJ).

The SA30AHB0G has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this TVS diode specification.

Substitute Part Grouping Explanation

Substitution of the SA30AHB0G is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters:

  • Voltage - Reverse Standoff (Typ): 30V
  • Voltage - Breakdown (Min): 33.3V
  • Voltage - Clamping (Max) @ Ipp: 64.3V
  • Current - Peak Pulse (10/1000µs): 10.8A
  • Power - Peak Pulse: 500W

Mechanical Parameters:

  • Package / Case: DO-204AC (DO-15) Axial
  • Mounting Type: Through Hole
  • Unidirectional Channels: 1

Compliance & Qualification:

  • Grade: Automotive
  • Qualification: AEC-Q101
