Equivalent & Substitute Parts for SA6.5A-E3/73

Part Overview

SA6.5A-E3/73 is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. It is designed to protect electronic circuits from transient voltage spikes and features a 6.5V reverse standoff voltage and a 500W peak pulse power rating. The part is supplied in a through-hole DO-204AC (DO-15) package and is compliant with ROHS3 and REACH standards. The product status is "Active". Identifying suitable alternatives is important for supply chain assurance, multisource qualification, and maintaining production continuity in case of inventory shortages.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on the following parameters: type (Zener), unidirectional channels (1), reverse standoff voltage (6.5V), breakdown voltage (min 7.22V), clamping voltage (max 11.2V), peak pulse current and power, package/mounting type (through hole, axial), package case/form factor, operating temperature, and compliance (RoHS3, REACH, MSL 1). Only parts matching these key electrical, mechanical, and compliance features are included in the substitution group.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute TVS diodes are defined as "Active" and are compliant with ROHS3, REACH, and meet a Moisture Sensitivity Level of 1 (Unlimited). These parts maintain the necessary compliance and certification requirements, as specified. Selection depends on inventory needs, package preference, and series origin without deviation from compliance requirements.

Frequently Asked Questions (FAQ)

Q1: What are the most critical parameters when selecting a substitute for SA6.5A-E3/73?
A1: Key parameters include type (Zener), number of unidirectional channels, standoff voltage (6.5V), breakdown voltage (min 7.22V), clamping voltage (max 11.2V), peak pulse capacity, mounting type (through-hole), package (DO-204AC/DO-201 variants), operating temperature range, and compliance (ROHS3, REACH, MSL 1).

Q2: Are all substitute TVS diodes in the same package format?
A2: SA6.5A-E3/73 and Taiwan Semiconductor SA6.5A are both in the DO-204AC (DO-15) axial package; Littelfuse LCE6.5A uses a DO-201AA (DO-27) axial package. Package size may vary slightly, and careful review of mechanical dimensions is advised for footprint matching.

Q3: Is electrical performance identical among all substitutes?
A3: All substitutes match the primary electrical protection parameters (standoff, breakdown, and clamping voltages). Differences are present in pulse current and power ratings as defined in the parameter comparison table.

Q4: Are the listed alternatives compliant with environmental and safety regulations?
A4: All alternatives are ROHS3 Compliant, REACH Unaffected, and have an MSL rating of 1 (Unlimited).

Q5: Can these substitutes be deployed in the same application as SA6.5A-E3/73?
A5: All provided substitute TVS diodes are categorized for general-purpose applications and provide the necessary electrical and environmental performance as outlined in the specification tables.
