LSM150 MELF Equivalent & Substitute Parts Reference

Part Overview

The LSM150 MELF, manufactured by Microchip Technology, is a Schottky diode in the Diodes, Rectifiers category. It features a reverse voltage rating of 50 V, an average rectified current of 1A, and a surface-mount DO-213AB (MELF) package. This part is currently active and available in inventory. It may be necessary to find alternative models to address supply chain requirements, design continuity, or compliance with assembly packaging preferences. Alternatives must match critical electrical, mechanical, and environmental parameters due to application requirements.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical when considering substitution between LSM150 MELF and BYM13-50-E3/96?
A1: Substitution is based on Schottky technology, maximum reverse voltage, average rectified current, recovery speed, forward voltage at 1A, leakage current, mounting type, package/case, temperature rating, RoHS, REACH, and MSL.

Q2: Are the LSM150 MELF and BYM13-50-E3/96 mechanically compatible?
A2: Both parts use the DO-213AB, MELF surface-mount package, indicating mechanical and footprint compatibility within the specified parameters.

Q3: Is there any difference in compliance or regulatory status between the parts?
A3: Both LSM150 MELF and BYM13-50-E3/96 are ROHS3 compliant, REACH unaffected, and have Moisture Sensitivity Level 1 (Unlimited).

Q4: What packaging differences exist between LSM150 MELF and BYM13-50-E3/96?
A4: The LSM150 MELF packaging is not specified beyond case, while BYM13-50-E3/96 is offered in Cut Tape (CT) and Digi-Reel® options.

Q5: Is the forward voltage or leakage current difference significant?
A5: BYM13-50-E3/96 features a maximum forward voltage of 700 mV @ 1 A compared to 580 mV @ 1 A for LSM150 MELF, and a lower reverse leakage (500 µA vs 1 mA). All values remain specified within the allowed boundaries for substitution in this category.
