SS12P3L-M3/87A Equivalent & Substitute Parts

Part Overview

The SS12P3L-M3/87A is an active Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 30 V DC reverse voltage with 12 A average rectified current capacity and is housed in a TO-277A (SMPC) package. The part belongs to the eSMP® series and is classified as a fast recovery diode with switching characteristics suitable for power conversion and rectification applications.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance are maintained across the component family. Alternative part numbers within the same base product line (SS12P3) provide equivalent functionality for applications requiring component sourcing flexibility or inventory optimization.

Parameter Comparison

Engineering Selection Recommendations

SS12P3L-M3/87A and SS12P3L-M3/86A: Both parts are standard-grade Schottky rectifier diodes with identical electrical and mechanical specifications. Selection between these two part numbers is based on inventory availability and supply chain considerations. Both maintain active product status and full ROHS3 compliance. The parts are interchangeable for all applications requiring 30 V, 12 A Schottky rectification in TO-277A surface mount packages.

SS12P3LHM3_A/H: This part is qualified to AEC-Q101 automotive standards and carries automotive-grade designation. The electrical performance is equivalent to the standard-grade variants across all critical parameters. The reverse leakage specification is measured at 20 V rather than 30 V; however, the leakage current value of 1 mA remains consistent. Selection of this part is appropriate for automotive applications requiring AEC-Q101 qualification or when automotive-grade components are specified in design requirements. This part maintains active product status and full ROHS3 compliance.

All three parts are manufactured by Vishay General Semiconductor - Diodes Division and share the same base product number (SS12P3), confirming parametric equivalence and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can SS12P3L-M3/86A be used as a direct replacement for SS12P3L-M3/87A?

A: Yes. Both parts are parametrically equivalent Schottky rectifier diodes with identical voltage ratings (30 V), current ratings (12 A), forward voltage characteristics (560 mV @ 12 A), and package specifications (TO-277A surface mount). No circuit modifications or PCB layout changes are required.

Q: What is the difference between SS12P3L-M3/87A and SS12P3LHM3_A/H?

A: The primary difference is qualification level. SS12P3LHM3_A/H carries AEC-Q101 automotive qualification and automotive-grade designation, while SS12P3L-M3/87A is standard-grade. Electrical performance and package specifications are equivalent. The reverse leakage measurement point differs (20 V vs. 30 V), but the leakage current value remains 1 mA. Selection depends on whether automotive qualification is required.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts use identical TO-277A (SMPC) surface mount packages with 3-PowerDFN case geometry. PCB footprints, solder pad layouts, and mounting procedures are identical across all three part numbers.

Q: What does RoHS3 compliance mean for these parts?

A: ROHS3 compliance indicates the parts meet Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specified brominated flame retardants. All three substitute parts carry ROHS3 compliance status.

Q: Can SS12P3LHM3_A/H be used in non-automotive applications?

A: Yes. The automotive-grade designation and AEC-Q101 qualification do not restrict use in non-automotive applications. The part maintains equivalent electrical and mechanical specifications and can be substituted in any application where the standard-grade variants are used.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has minimal moisture sensitivity and does not require special moisture control during storage, handling, or assembly. These parts can be stored and handled under standard industrial conditions without moisture-related degradation.

Q: Are there any temperature operating differences between the substitute parts?

A: No. All three parts operate across the identical junction temperature range of -55°C to 150°C, ensuring equivalent thermal performance in all operating environments.
