SA30CA B0G Equivalent & Substitute Parts

Part Overview

The SA30CA B0G is a transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation, designed for general-purpose overvoltage protection applications. This component features a 30V reverse standoff voltage with a 64.3V maximum clamping voltage and 10.8A peak pulse current capability in a through-hole DO-204AC (DO-15) axial package. The SA30CA 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 SA30CA B0G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for voltage ratings (30V reverse standoff, 33.3V minimum breakdown, 64.3V maximum clamping), current handling (10.8A peak pulse), power dissipation (500W peak pulse), operating temperature range (-55°C to 175°C), and physical form factor (DO-204AC through-hole axial package). The TVS diode category, zener type classification, and single bidirectional channel configuration must also remain constant. Compliance certifications including RoHS3 and REACH status must be preserved to ensure regulatory compatibility in target applications.

Parameter Comparison

Engineering Selection Recommendations

The SA30CA A0G serves as a direct functional equivalent to the SA30CA B0G. Both components are manufactured by Taiwan Semiconductor Corporation within the SA series and maintain identical electrical specifications across all voltage, current, and power parameters. The SA30CA A0G is currently in active product status, whereas the SA30CA B0G is discontinued, making the A0G variant the appropriate selection for new designs and ongoing production requirements. Both parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in target applications. The SA30CA A0G demonstrates superior inventory availability with 1005 pieces in stock compared to 849 pieces for the discontinued B0G variant. Physical form factor, thermal operating range, and package configuration are identical between both parts, enabling direct substitution without circuit board redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can the SA30CA A0G be used as a direct replacement for the SA30CA B0G in existing designs?

A: Yes. The SA30CA A0G is electrically and mechanically identical to the SA30CA B0G across all specified parameters. Both components feature identical 30V reverse standoff voltage, 64.3V clamping voltage, 10.8A peak pulse current, and DO-204AC through-hole axial packaging. Direct substitution requires no circuit modifications.

Q: What is the difference between the SA30CA B0G and SA30CA A0G part numbers?

A: The difference between B0G and A0G designations reflects manufacturing date codes or production batches from Taiwan Semiconductor Corporation. Both variants are identical in electrical performance, package type, and compliance certifications. The A0G variant is currently in active production status.

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

A: No. Both the SA30CA B0G and SA30CA A0G maintain identical RoHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL) is 1 (Unlimited) for both variants, and both carry the same ECCN and HTSUS classifications.

Q: Why is the SA30CA B0G discontinued if the A0G is functionally identical?

A: Product discontinuation typically reflects manufacturing transitions, inventory management, or supplier consolidation decisions rather than technical obsolescence. The SA30CA A0G remains in active production and provides equivalent performance for all applications previously served by the B0G variant.

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

A: Substitution eligibility is determined by matching the following parameters: reverse standoff voltage (30V), breakdown voltage minimum (33.3V), clamping voltage maximum (64.3V), peak pulse current (10.8A), peak pulse power (500W), operating temperature range (-55°C to 175°C), package type (DO-204AC axial through-hole), and compliance certifications (RoHS3, REACH).

Q: Can other SA series TVS diodes substitute for the SA30CA B0G?

A: No. Only components with identical voltage ratings, current specifications, and package configurations qualify as substitutes. Other SA series variants with different voltage or current ratings are not interchangeable and would alter circuit protection characteristics.

Q: Is the through-hole DO-204AC package critical for substitution?

A: Yes. The DO-204AC (DO-15) axial through-hole package is a critical parameter. Surface-mount alternatives or different package types would require circuit board redesign and are not considered direct substitutes.
