SA24A B0G Equivalent & Substitute Parts

Part Overview

The SA24A B0G is a unidirectional 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 SA24A B0G is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and maintenance applications. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitute parts for the SA24A B0G are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• 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
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Parameters (Must Match Exactly):

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

Compliance & Certification (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Only parts meeting all specified criteria are classified as direct substitutes. Parts from the same manufacturer series (SA) with identical base product number (SA24) and matching electrical/mechanical specifications are eligible for substitution.

Parameter Comparison

Engineering Selection Recommendations

The SA24A A0G is a direct equivalent substitute for the discontinued SA24A B0G. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, mechanical packaging, and compliance certifications.

Selection Basis:

The SA24A A0G meets all substitution criteria:

• Identical voltage ratings (24V reverse standoff, 26.7V breakdown minimum, 50.1V clamping maximum)
• Identical current handling (13.4A peak pulse)
• Identical power dissipation (500W peak pulse)
• Identical operating temperature range (-55°C to 175°C junction temperature)
• Identical mechanical form factor (DO-204AC/DO-15 axial through-hole package)
• Identical compliance status (ROHS3 Compliant, REACH Unaffected, MSL 1)

The primary distinction is product status: SA24A A0G is currently active with 724 units in stock, whereas SA24A B0G is discontinued. The SA24A A0G provides direct pin-for-pin and functional replacement capability without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can SA24A A0G be used as a direct replacement for SA24A B0G in existing designs?
