Equivalent & Substitute Parts Reference: SS12P4CHM3_A/I

Part Overview

The SS12P4CHM3_A/I is an active automotive-grade Schottky rectifier diode array from Vishay General Semiconductor – Diodes Division, belonging to the eSMP® series. It features a 1 pair common cathode configuration, rated at 40 V maximum DC reverse voltage and 6A average rectified current per diode, with fast recovery and surface mount compatibility in TO-277, 3-PowerDFN package. Circumstances such as supply chain constraints, lead time management, or stock availability often necessitate seeking alternative models with identical parametric specifications and certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification is based strictly on identical electrical and mechanical parameters: diode configuration (1 pair common cathode), technology (Schottky), voltage and current ratings (40 V Vr, 6A Io), voltage forward maximum, speed specification, reverse leakage, operating temperature, package type (TO-277, 3-PowerDFN), mounting type, automotive qualification (AEC-Q101), and compliance certifications (RoHS3, REACH). Only items matching all listed critical parameters are considered as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both the SS12P4CHM3_A/I and SS12P4C-M3/86A are active eSMP® series Schottky rectifier diodes with full compliance to ROHS3 and REACH standards, AEC-Q101 qualification, and unlimited moisture sensitivity level (MSL 1). Consistent parameter sets and certification status indicate equivalence for applications requiring identical technical and safety standards.

Frequently Asked Questions (FAQ)

Q: What parameters must match for direct substitution of Schottky rectifier diodes in this category?
A: Substitution requires identical diode configuration, technology type, voltage and current ratings, forward voltage at rated current, switching speed, reverse leakage, operating temperature, package type, automotive qualification, and compliance certifications.

Q: Is package compatibility assured between SS12P4CHM3_A/I and SS12P4C-M3/86A?
A: Both devices use the TO-277, 3-PowerDFN package and TO-277A (SMPC) supplier device package, ensuring mechanical compatibility for surface mount applications.

Q: Do both alternatives meet automotive and environmental compliance requirements?
A: Both components are automotive grade with AEC-Q101 qualification, ROHS3 compliant, and unaffected by REACH, supporting use in automotive and regulated environments.

Q: Can the substitute part be used in legacy designs without modification?
A: Provided all technical parameters and package specifications match, legacy designs may utilize the substitute without changes to the board layout or environmental qualification process.

Q: How does inventory availability vary between the main and substitute parts?
A: Inventory levels are specific to stocking status; SS12P4CHM3_A/I lists 1021 pieces available while SS12P4C-M3/86A lists 3600 pieces available. Availability must be confirmed per project requirements.
