SA12CA B0G Equivalent & Substitute Parts

Part Overview

The SA12CA B0G is a transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose overvoltage protection applications. This component features a 12V reverse standoff voltage with a 19.9V maximum clamping voltage and 26.3A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package format.

The SA12CA B0G is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures continued availability for circuit protection applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by strict equivalence across electrical performance parameters and mechanical compatibility. The SA12CA B0G can be substituted with alternative part numbers that maintain identical specifications in the following critical areas:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff: 12V
• Voltage - Breakdown (Min): 13.3V
• Voltage - Clamping (Max) @ Ipp: 19.9V
• Current - Peak Pulse (10/1000µs): 26.3A
• Power - Peak Pulse: 500W
• Bidirectional Channels: 1

Mechanical Parameters (Must Match):

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

Compliance & Environmental (Must Match):

• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: -55°C ~ 175°C (TJ)

Substitute parts must originate from the same manufacturer series (SA) and maintain identical zener diode type classification to ensure functional equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The SA12CA A0G serves as a direct substitute for the discontinued SA12CA B0G. Both components are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical and mechanical specifications across all critical parameters.

The SA12CA A0G is currently in active product status with 884 pieces available in new original inventory, providing immediate availability for replacement applications. Both parts carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements.

Selection of the SA12CA A0G over the SA12CA B0G is appropriate for all applications previously utilizing the main part number, as no electrical performance degradation or mechanical incompatibility exists between these components.

Frequently Asked Questions (FAQ)

Q: Can the SA12CA A0G be used as a direct replacement for the SA12CA B0G?

A: Yes. The SA12CA A0G is electrically and mechanically equivalent to the SA12CA B0G. Both components share identical voltage ratings (12V reverse standoff, 19.9V clamping), current specifications (26.3A peak pulse), power dissipation (500W), package format (DO-204AC/DO-15 axial), and operating temperature range (-55°C to 175°C).

Q: What is the difference between the SA12CA B0G and SA12CA A0G part numbers?

A: The difference between these part numbers reflects manufacturing date codes or supplier lot designations. The electrical and mechanical specifications remain identical. The SA12CA A0G is currently in active production status, while the SA12CA B0G is discontinued.

Q: Are both parts suitable for the same circuit protection applications?

A: Yes. Both the SA12CA B0G and SA12CA A0G are designed for general-purpose transient voltage suppression. They provide identical protection characteristics for circuits requiring 12V standoff voltage with 19.9V maximum clamping voltage.

Q: What is the DO-204AC package format?

A: The DO-204AC, also designated DO-15, is an axial through-hole package format for diodes. This package style features two leads extending from opposite ends of a cylindrical component body, suitable for insertion into through-hole PCB mounting applications.

Q: Are there any compliance differences between these parts?

A: No. Both the SA12CA B0G and SA12CA A0G carry identical RoHS3 compliance certification, REACH unaffected status, and Moisture Sensitivity Level 1 (unlimited) rating.

Q: What inventory status should I consider when selecting between these parts?

A: The SA12CA A0G has 884 pieces in new original stock and active product status. The SA12CA B0G is discontinued at DiGi Electronics with 743 pieces remaining in inventory. For new designs or long-term production requirements, the SA12CA A0G is the appropriate selection due to its active status and continued availability.
