SARS01V0 Equivalent & Substitute Parts Reference

Part Overview

The SARS01V0 from Sanken Electric USA Inc. is a general-purpose diode with an 800 V reverse voltage rating and a 1.2A average rectified current in an axial through-hole package. It is an active component widely utilized in rectification and protection applications. Finding alternative models is necessary for supply chain resilience, drop-in replacement flexibility, and maintaining RoHS compliance in assembly lines.

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching the following key parameters: voltage rating (Vr), average rectified current (Io), forward voltage (Vf), standard recovery speed, reverse recovery time (if defined), reverse leakage current, mounting type, package / case, operating temperature, and RoHS compliance. Only parts with equivalent or greater values in these categories, and with direct through-hole axial package compatibility, are included.

Engineering Selection Recommendations

All listed substitute diodes are active, RoHS or ROHS3 compliant, and have an MSL rating of 1 (Unlimited). Compliance and active product status ensure applicability for direct substitution in designs requiring SARS01V0, SARS01V1, EM 2BV1, 1N5398-E3/54, or GP15K-E3/54.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical for substituting SARS01V0 in my design?
A1: Critical parameters include DC reverse voltage rating, average rectified current, forward voltage, recovery speed, reverse leakage current, mounting type, package compatibility, operating temperature, and RoHS compliance.

Q2: How do I verify package compatibility for these diode rectifiers?
A2: Verify that the package/case specification matches Axial, DO-204AL (DO-41), or DO-204AC (DO-15) as noted for each part, ensuring compatibility with the original SARS01V0 through-hole design.

Q3: Are all listed substitutes environmentally compliant?
A3: All substitute diodes are listed as RoHS or ROHS3 compliant with MSL 1, meeting standard environmental requirements.

Q4: What is the difference between “Parametric Equivalent” and “Similar” in this context?
A4: “Parametric Equivalent” substitutes exactly match the main parameters specified for SARS01V0. “Similar” substitutes match the main functionality but may have higher maximum values for certain parameters, such as current or temperature range.

Q5: Will reverse recovery time affect substitutability?
A5: Reverse recovery time is matched as provided, and any deviation is indicated for each substitute. Selection should consider this only within the specified values.

Q6: Can I mix parts from different manufacturers in the same design?
A6: As long as key parameters, package type, and compliance status match, parts from different manufacturers listed here may be used in the same design without alteration to the PCB layout.
