SARS01W Equivalent & Substitute Parts Reference

Part Overview

The SARS01W, manufactured by Sanken Electric USA Inc., is an 800 V, 1.2A general-purpose axial diode for through hole mounting in standard recovery applications. The device is currently listed as active and available in new original stock. Diode, rectifier, and axial package substitutions are sometimes necessary in electronic designs owing to factors such as inventory availability, compliance with RoHS standards, or compatibility with preferred package formats.

Substitute Part Grouping Explanation

Substitute part selection is strictly based on the following parameters: rated reverse voltage, average rectified current, forward voltage at specified current, reverse recovery time, reverse leakage current, mounting type, operating temperature range, package/case, RoHS compliance, moisture sensitivity level, and product status. All substitute parts fall under the same category (Diodes, Rectifiers) and offer through hole mounting with axial packages. Only parts meeting or exceeding the required electrical, mechanical, and compliance parameters are included.

Engineering Selection Recommendations

The SARS01W and its substitutes, GP15K-E3/54 and 1N5398-E3/54, are all listed as active products and are available in original new stock. All parts have RoHS compliance and a Moisture Sensitivity Level of 1 (Unlimited), which permits unrestricted storage conditions. Substitutes meet or exceed the original part's electrical ratings and environmental requirements. The alternative parts are suitable for selection in applications requiring diode, rectifier, and axial through hole formats with similar compliance standards.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched for a substitute diode in this category?
A1: Rated reverse voltage, average rectified current, forward voltage (Vf) at specified current, reverse recovery time (trr), reverse leakage current, mounting type, package/case, operating temperature range, RoHS compliance, moisture sensitivity level, and product status.

Q2: Are alternate package/case types acceptable for substitution?
A2: Substitute diodes listed here use axial through hole mounting, matching the SARS01W. Variations such as DO-204AL (DO-41) and DO-204AC (DO-15) are industry-standard axial formats compatible with axial mounting requirements.

Q3: How does RoHS and MSL affect substitute selection?
A3: All listed diodes are RoHS compliant and have a Moisture Sensitivity Level of 1 (Unlimited), matching the compliance required for unrestricted use and handling.

Q4: Are higher current ratings acceptable in substitutes?
A4: Substitutes presented here have average rectified current ratings equal to or greater than the SARS01W, meeting the criteria for substitution in the intended application.

Q5: What are the considerations for reverse recovery time and leakage current?
A5: Substitutes exhibit reverse recovery times and leakage currents that meet or improve upon the original specifications, ensuring consistency in performance for standard recovery rectifier applications.
