SA15CA B0G Equivalent & Substitute Parts

Part Overview

The SA15CA B0G is a transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose overvoltage protection applications. This component features a 15V reverse standoff voltage with a 24.4V maximum clamping voltage and 21A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package format.

The SA15CA B0G is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this TVS diode specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA15CA B0G is determined by electrical and mechanical parameter equivalence within the TVS diode category. The following parameters establish substitution validity:

Critical Electrical Parameters:

• Voltage - Reverse Standoff (Typ): 15V
• Voltage - Breakdown (Min): 16.7V
• Voltage - Clamping (Max) @ Ipp: 24.4V
• Current - Peak Pulse (10/1000µs): 21A
• Power - Peak Pulse: 500W
• Bidirectional Channels: 1
• Type: Zener

Critical Mechanical Parameters:

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

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts must match all critical electrical parameters and the mechanical package specification. Variations in packaging format (such as cut tape versus bulk packaging) do not affect electrical substitution validity.

Parameter Comparison

Engineering Selection Recommendations

The SA15CA A0G is a direct electrical equivalent to the SA15CA B0G, with identical performance across all critical TVS diode parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power.

Substitution Validity:

The SA15CA A0G meets all electrical and mechanical substitution criteria. Both components are manufactured by Taiwan Semiconductor Corporation, share the same base product number (SA15), and are packaged in the identical DO-204AC (DO-15) through-hole axial format. Both components maintain ROHS3 compliance and REACH unaffected status.

Operational Consideration:

The SA15CA A0G specifies an operating temperature range of -55°C to 150°C (TJ), compared to the SA15CA B0G range of -55°C to 175°C (TJ). Applications requiring sustained operation above 150°C junction temperature require evaluation against the substitute part's thermal specification.

Availability Advantage:

The SA15CA A0G maintains active product status with 828 pieces in stock, providing supply continuity for the discontinued SA15CA B0G. The substitute part is available in cut tape packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SA15CA A0G be used as a direct replacement for the SA15CA B0G in existing designs?

A: Yes. The SA15CA A0G is electrically and mechanically equivalent to the SA15CA B0G across all critical TVS diode parameters, including voltage ratings, current capacity, and package format. Both components are through-hole axial devices in the DO-204AC package with identical electrical performance specifications.

Q: What is the difference between the SA15CA B0G and SA15CA A0G?

A: The primary differences are product status and packaging format. The SA15CA B0G is discontinued at DiGi Electronics, while the SA15CA A0G maintains active status. The SA15CA A0G is supplied in cut tape packaging, whereas the SA15CA B0G packaging format is not specified. The operating temperature range differs slightly: SA15CA B0G operates to 175°C (TJ), while SA15CA A0G operates to 150°C (TJ).

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SA15CA B0G and SA15CA A0G maintain identical compliance status: ROHS3 compliant and REACH unaffected. Both components carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Does the cut tape packaging of the SA15CA A0G affect its electrical performance?

A: No. Packaging format does not affect electrical performance. Cut tape packaging is a supply format suitable for automated assembly processes and does not alter the component's electrical characteristics, voltage ratings, or current capacity.

Q: What applications are these TVS diodes suitable for?

A: Both the SA15CA B0G and SA15CA A0G are rated for general-purpose transient voltage suppression applications. They are not designated for power line protection applications.

Q: Can these components be used in applications requiring operation above 150°C junction temperature?

A: The SA15CA A0G is specified for operation up to 150°C (TJ). Applications requiring sustained operation above 150°C should reference the SA15CA B0G specification of 175°C (TJ), or identify alternative TVS diodes with higher temperature ratings.
