SS24HM3_A/I Equivalent & Substitute Parts Reference

Part Overview

The component with manufacturer part number SS24HM3_A/I is a Schottky rectifier diode from Vishay General Semiconductor, belonging to the Diodes, Rectifiers category. It is supplied in tape & reel packaging and is housed in a DO-214AA (SMB) surface-mount package. With a maximum reverse voltage of 40 V and an average rectified current rating of 2A, this diode supports fast recovery operation and automotive-grade compliance (AEC-Q101). The part maintains an active status and is RoHS3 compliant.

Alternative models, or parametric equivalents, are often required to ensure supply chain resilience, maintain production when primary inventory is unavailable, or fulfill strict compliance and quality requirements as demonstrated by AEC-Q101 qualification or RoHS status.

Engineering Selection Recommendations

All listed substitute parts are active status, RoHS3 compliant, and available in surface-mount DO-214AA (SMB) packages. Where specified, AEC-Q101 qualification and MSL of 1 (unlimited) are retained. Selection can be carried out based strictly on inventory availability, manufacturer preference, and required compliance documentation. Only parts matching the minimum specified parameters and certifications are shown.

Frequently Asked Questions (FAQ)

Q: What criteria were used to identify equivalent substitute diodes for SS24HM3_A/I?
A: Substitutes are selected based on matching technology, maximum reverse voltage, average rectified current, forward voltage at rated current, recovery speed, reverse leakage current at maximum reverse voltage, mounting type, package, operating temperature range, environmental compliance (RoHS3), moisture sensitivity level, and qualification where specified.

Q: Are all substitute parts available in the same package as SS24HM3_A/I?
A: Yes. All substitutes are specified in the DO-214AA (SMB) surface-mount package, which ensures form and footprint compatibility.

Q: Do substitute parts meet automotive and environmental specifications?
A: Substitute parts from Vishay General Semiconductor (SS24HE3_A/H, SS24HE3_A/I) and Diodes Incorporated (B240Q-13-F) specify AEC-Q101 qualification. All substitutes are RoHS3 compliant.

Q: Is the current and voltage rating identical for all listed substitutes?
A: Yes. All listed substitutes specify a 40 V maximum reverse voltage and 2A average rectified current.

Q: Are the reverse leakage and forward voltage drop the same across substitutes?
A: Forward voltage (500 mV @ 2A) is identical. Reverse leakage is 400 µA or 500 µA at 40 V, within the constraints provided.

Q: Are there differences in the supplier device package designation?
A: Some suppliers refer to DO-214AA as "SMB" or "DO-214AA (SMB)" but dimensions and mounting format are equivalent according to the provided data.
