SS12P2LHM3_A/H Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS12P2LHM3_A/H is an active Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at 20V DC reverse voltage with a 12A average rectified current rating and is housed in a TO-277A (SMPC) package. The device is qualified to AEC-Q101 automotive standards and maintains RoHS3 compliance with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when component availability becomes limited, supply chain disruptions occur, or inventory requirements necessitate alternative sourcing from the same manufacturer's product line while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the SS12P2LHM3_A/H is limited to parts that maintain identical electrical performance across all critical parameters. The substitution logic is based on the following key parameters that determine functional equivalence:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 20 V
• Current - Average Rectified (Io): 12 A
• Voltage - Forward (Vf) (Max) @ If: 560 mV @ 12 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 1 mA @ 20 V
• Capacitance @ Vr, F: 930 pF @ 4V, 1MHz

Mechanical Parameters (Must Match Exactly):

• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Supplier Device Package: TO-277A (SMPC)

Compliance Parameters (Must Match Exactly):

• Technology: Schottky
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Operating Temperature - Junction: -55°C to 150°C

The SS12P2L-M3/86A meets all substitution criteria as a parametric equivalent manufactured by the same supplier with identical electrical, mechanical, and compliance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SS12P2LHM3_A/H and SS12P2L-M3/86A are active products manufactured by Vishay General Semiconductor - Diodes Division. Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical performance differences.

SS12P2LHM3_A/H is suitable for applications where this specific part number is specified in design documentation or procurement requirements.

SS12P2L-M3/86A is suitable as a direct substitute when the primary part number is unavailable. This part maintains identical electrical specifications, mechanical compatibility, and compliance certifications. The substitute part is part of the eSMP® series designation and carries significantly higher inventory availability (32,300 pieces versus 670 pieces).

Both parts satisfy automotive-grade requirements with AEC-Q101 qualification, RoHS3 compliance, and unlimited moisture sensitivity level (MSL 1). Both operate across the identical temperature range of -55°C to 150°C junction temperature.

Frequently Asked Questions (FAQ)

Q: Can SS12P2L-M3/86A be used as a direct replacement for SS12P2LHM3_A/H in existing designs?

A: Yes. The SS12P2L-M3/86A is a parametric equivalent with identical electrical specifications (20V reverse voltage, 12A average rectified current, 560mV forward voltage at 12A), identical mechanical package (TO-277A SMPC), and identical compliance certifications (AEC-Q101, RoHS3). No circuit modifications are required.

Q: Are there any differences in the package or pinout between these two parts?

A: No. Both parts use the TO-277, 3-PowerDFN package with TO-277A (SMPC) supplier device package designation. Pinout and mechanical dimensions are identical.

Q: Do both parts meet automotive qualification requirements?

A: The SS12P2LHM3_A/H carries explicit automotive grade designation with AEC-Q101 qualification. The SS12P2L-M3/86A is manufactured by the same automotive-qualified division of Vishay and carries RoHS3 compliance and MSL 1 rating. Specific automotive grade and AEC-Q101 qualification status for the substitute part is not provided in the available technical data.

Q: What is the difference between the part number designations?

A: Both parts share the base product number SS12P2. The SS12P2LHM3_A/H and SS12P2L-M3/86A represent different manufacturing codes or tape reel configurations from Vishay's product line. The SS12P2L-M3/86A is designated as part of the eSMP® series.

Q: Which part should be selected for new designs?

A: Selection should be based on design specification requirements and supply chain availability. Both parts are active products with identical electrical and mechanical performance. The SS12P2L-M3/86A offers significantly higher inventory availability.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the identical junction temperature range (-55°C to 150°C) and maintain identical electrical characteristics including forward voltage (560mV @ 12A), reverse leakage current (1mA @ 20V), and capacitance (930pF @ 4V, 1MHz).
