SA17CA B0G Equivalent & Substitute Parts

Part Overview

The SA17CA B0G is a transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose overvoltage protection applications. This component features a 17V reverse standoff voltage with a 27.7V maximum clamping voltage and 19A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package. The SA17CA B0G is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain design continuity and ensure component availability for production and repair applications.

• Voltage - Clamping (Max) @ Ipp: 27.7V
• Current - Peak Pulse (10/1000µs): 19A
• Power - Peak Pulse: 500W
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Parameters (Required Match):

• Package / Case: DO-204AC, DO-15, Axial
• Mounting Type: Through Hole
• Bidirectional Channels: 1

Device Type (Required Match):

• Type: Zener
• Category: Transient Voltage Suppressors (TVS)
• Series: SA
• Manufacturer: Taiwan Semiconductor Corporation

The SA17CA A0G meets all substitution criteria and is classified as a direct equivalent.
