LSM535J/TR13 Equivalent & Substitute Parts Reference

Part Overview

The LSM535J/TR13, manufactured by Microchip Technology, is a Schottky rectifier diode categorized under Diodes, Rectifiers, with a voltage rating of 35 V and a current rating of 5A. It features a fast recovery time, low forward voltage drop, and is packaged in a DO-214AB (SMC) surface mount case. The part is currently active but specified as RoHS non-compliant. When compliance or supply chain constraints are encountered, it is necessary to identify alternative models with matching electrical, mechanical, and reliability parameters for critical design requirements without deviating from specified product performance.

Substitute Part Grouping Explanation

Substitution is based strictly on the following key parameters: technology (Schottky), voltage–DC reverse rating, forward current, maximum forward voltage at rated current, reverse leakage current, recovery speed, package type (DO-214AB/SMC), mounting method (surface mount), and junction operating temperature range. Substitutes are selected from the Diodes, Rectifiers product category, ensuring equivalency within these critical parameters for functionality and form factor compatibility.

Engineering Selection Recommendations

When selecting equivalent or substitute Schottky rectifier diodes strictly from the provided list, ensure that compliance with RoHS is prioritized if required. Both B530C-13-F and SSC53LHE3_A/H are listed as ROHS3 compliant, whereas LSM535J/TR13 is RoHS non-compliant. The product status for all candidates is active, and all parts meet the same moisture sensitivity and REACH criteria. Additional certifications, such as AEC-Q101 automotive qualification for SSC53LHE3_A/H, are present only if specified.

Frequently Asked Questions (FAQ)

Q1: What are the core criteria for substituting the LSM535J/TR13 Schottky rectifier?
A1: Only parts with matching technology (Schottky), rated current (5A), comparable reverse voltage, forward voltage, recovery speed, and the same package/case (DO-214AB, SMC) are considered valid substitutes.

Q2: Can a diode with a lower reverse voltage rating be used as a substitute?
A2: Substitute selection is limited strictly to the provided parts. B530C-13-F and SSC53LHE3_A/H both have a 30 V rating versus the original’s 35 V.

Q3: How important is package compatibility during substitution?
A3: Only diodes with the DO-214AB (SMC) surface mount package are considered equivalent to ensure physical compatibility and ease of assembly.

Q4: Are the substitute options compliant with environmental standards?
A4: B530C-13-F and SSC53LHE3_A/H are ROHS3 compliant. The original part, LSM535J/TR13, is RoHS non-compliant.

Q5: Do any substitutes provide automotive-grade qualification?
A5: Of the substitutes, SSC53LHE3_A/H includes AEC-Q101 automotive qualification as part of its specifications.
