SA26CA B0G Equivalent & Substitute Parts

Part Overview

The SA26CA B0G is a transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose overvoltage protection applications. This component features a 26V reverse standoff voltage with a 53.5V maximum clamping voltage and 12.4A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package. The SA26CA 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA26CA B0G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for voltage ratings (26V reverse standoff, 28.9V minimum breakdown, 53.5V maximum clamping), current handling (12.4A peak pulse), power dissipation (500W peak pulse), temperature operating range (-55°C to 175°C), and physical form factor (DO-204AC through-hole axial package). The SA26CA A0G meets all these criteria as a direct functional equivalent, differing only in product status and inventory availability. Both parts are manufactured by Taiwan Semiconductor Corporation within the SA series and share identical electrical performance characteristics and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SA26CA A0G is the direct equivalent substitute for the discontinued SA26CA B0G. Both components are manufactured by Taiwan Semiconductor Corporation and provide identical electrical performance and physical characteristics. The SA26CA A0G maintains active product status, ensuring ongoing availability and supply chain continuity. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Selection of the SA26CA A0G as a replacement for the SA26CA B0G introduces no design modifications, circuit re-evaluation, or performance trade-offs. The substitute part is suitable for direct board-level replacement in existing designs without PCB layout changes or application circuit adjustments.

Frequently Asked Questions (FAQ)

Q: Can the SA26CA A0G be used as a direct replacement for the SA26CA B0G in existing circuit designs?

A: Yes. The SA26CA A0G is electrically and mechanically identical to the SA26CA B0G. All voltage ratings, current specifications, temperature operating range, and package form factor are equivalent. Direct substitution requires no circuit modifications or design changes.

Q: What is the primary reason for substituting the SA26CA B0G?

A: The SA26CA B0G is discontinued at DiGi Electronics. The SA26CA A0G provides identical functionality with active product status and confirmed inventory availability.

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

A: No. Both the SA26CA B0G and SA26CA A0G carry identical RoHS3 compliance and REACH unaffected status. No additional compliance verification is required when substituting between these parts.

Q: Do these parts require different PCB footprints or mounting procedures?

A: No. Both parts use the DO-204AC (DO-15) axial through-hole package. PCB layout, footprint, and mounting procedures remain unchanged.

Q: What are the critical electrical parameters that define substitution eligibility for this TVS diode?

A: Substitution eligibility is determined by matching the reverse standoff voltage (26V), breakdown voltage (28.9V minimum), clamping voltage (53.5V maximum), peak pulse current (12.4A), peak pulse power (500W), and operating temperature range (-55°C to 175°C). The SA26CA A0G matches all these parameters.

Q: Is the SA26CA A0G available in the same package as the SA26CA B0G?

A: Yes. Both parts are supplied in the DO-204AC (DO-15) axial through-hole package configuration.
