SA24CA B0G Equivalent & Substitute Parts

Part Overview

The SA24CA B0G is a transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose overvoltage protection applications. This component features a 24V reverse standoff voltage with a 50.1V maximum clamping voltage and 13.4A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package. The SA24CA 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.

Substitute Part Grouping Explanation

Substitution of the SA24CA B0G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for voltage protection characteristics, peak pulse current handling, power dissipation capability, and physical package configuration to ensure direct functional replacement without circuit redesign.

The following parameters establish substitution validity:

• Voltage - Reverse Standoff (Typ): 24V
• Voltage - Breakdown (Min): 26.7V
• Voltage - Clamping (Max) @ Ipp: 50.1V
• Current - Peak Pulse (10/1000µs): 13.4A
• Power - Peak Pulse: 500W
• Package / Case: DO-204AC (DO-15), Axial
• Mounting Type: Through Hole
• Type: Zener, Bidirectional (1 channel)
• Operating Temperature Range: -55°C to 175°C (TJ)

Parameter Comparison

Engineering Selection Recommendations

The SA24CA A0G serves as a direct functional equivalent to the SA24CA B0G. Both components are manufactured by Taiwan Semiconductor Corporation within the SA series and share identical electrical specifications across all critical parameters including voltage ratings, current handling, and power dissipation characteristics. The physical package configuration, mounting type, and thermal operating range are identical between both parts.

The primary distinction between these components is product status: the SA24CA B0G is discontinued at DiGi Electronics, while the SA24CA A0G maintains active status with confirmed inventory availability (1038 pieces in stock). Both parts maintain equivalent compliance certifications including ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels.

For applications requiring the SA24CA B0G specifications, the SA24CA A0G provides complete electrical and mechanical compatibility without requiring circuit modifications or design changes. The active product status of the SA24CA A0G ensures ongoing availability and supply chain continuity.
