SS13M Equivalent & Substitute Parts Reference

Part Overview

The SS13M, manufactured by Taiwan Semiconductor Corporation, is an active Schottky diode rectifier designed for surface mount applications in the Micro SMA package. It supports up to 30 V reverse voltage and 1 A average rectified current, optimized for fast recovery and low forward voltage drop. Identifying substitute parts is essential for ensuring continued supply, design flexibility, and maintenance of product lifecycle in applications requiring strict electrical and mechanical equivalency within the diodes, rectifiers category.

Substitute Part Grouping Explanation

Substitution is based only on matching technology (Schottky), voltage rating (30 V), rectified current (1 A), forward voltage at rated current, speed classification, mounting method (surface mount), and package type relevant to surface-mount applications. Additional requirements include product status being active, RoHS3 compliance, MSL 1 (Unlimited), and REACH unaffected status. Only parts matching all listed key parameters are confirmed as equivalent substitutes within the diodes, rectifiers category.

Engineering Selection Recommendations

Both SS13M and SS13_R1_00001 have active product status and comply with RoHS3 and REACH requirements. Each part has a Moisture Sensitivity Level (MSL) of 1 (Unlimited), ECCN classification EAR99, and HTSUS code 8541.10.0080. The presented substitutes are suitable for direct selection within the defined regulatory and compliance scope.

Frequently Asked Questions (FAQ)

Q: Which parameters are required for confirming equivalency of diode rectifiers in substitution?
A: Substitution is confirmed only if technology (Schottky), reverse voltage rating, average rectified current, forward voltage at specified current, recovery speed, mounting type, package/case, product status, RoHS3, REACH, and MSL requirements are matched.

Q: Is difference in reverse leakage or capacitance @ Vr a substitution barrier?
A: Reverse leakage and capacitance at specified conditions are included in the comparison; substantial variance must be considered within applications where these parameters are critical.

Q: Are Micro SMA and SMA (DO-214AC) interchangeable for surface mount designs?
A: Only packages explicitly listed in both main and substitute parts are presented. Mechanical compatibility must be verified within the defined package constraints.

Q: Do temperature rating differences affect suitability?
A: Operating temperature ratings are provided. Selection is limited to the specified range for each part.

Q: Are regulatory standards equivalently met by all substitutes listed?
A: All listed substitutes are RoHS3 compliant and REACH unaffected, with MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8541.10.0080. This ensures compliance is maintained within the diodes, rectifiers category.
