SS8P2LHM3_A/I Equivalent & Substitute Parts

Part Overview

The SS8P2LHM3_A/I is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, classified within the eSMP® series. This surface mount component operates at 20 V DC reverse voltage with an 8 A average rectified current rating and is packaged in the TO-277A (SMPC) form factor. The device is actively produced and holds AEC-Q101 automotive qualification with ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category, enabling component interchangeability for procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS8P2LHM3_A/I are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is founded on the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 20 V
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 570 mV @ 8 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 200 µA @ 30 V
• Capacitance @ Vr, F: 330 pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Technology: Schottky
• Package / Case: TO-277, 3-PowerDFN
• Supplier Device Package: TO-277A (SMPC)
• Operating Temperature - Junction: -55°C to 150°C
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance, thermal operating range, package footprint, and automotive qualification status. Packaging format variations (Tape & Reel versus Cut Tape & Digi-Reel®) do not affect functional equivalence and are determined by procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

SS8P2LHM3_A/I (Primary Part)

The SS8P2LHM3_A/I is the reference component and remains the primary selection for new designs and production applications. This part carries active product status, full automotive qualification (AEC-Q101), and is supplied in Tape & Reel packaging format. Current inventory of 954 pieces supports immediate procurement requirements.

SS8P2LHM3_A/H (Preferred Substitute)

The SS8P2LHM3_A/H is the preferred substitute for the SS8P2LHM3_A/I. Both parts are identical in all electrical and mechanical parameters, maintain automotive grade classification with AEC-Q101 qualification, and are supplied in Tape & Reel packaging. The SS8P2LHM3_A/H carries active product status with higher inventory availability (2105 pieces), making it suitable for direct substitution in existing designs and production environments.

SS8P2L-M3/86A (Alternative Substitute)

The SS8P2L-M3/86A provides electrical and mechanical equivalence to the SS8P2LHM3_A/I across all critical parameters. This part differs in packaging format (Cut Tape & Digi-Reel®) and does not carry explicit automotive grade or AEC-Q101 qualification designation in the provided specifications. The SS8P2L-M3/86A is suitable for applications where automotive qualification is not required and offers the highest inventory availability (12300 pieces). Selection of this part requires confirmation that automotive-grade qualification is not a design or regulatory requirement.

Frequently Asked Questions (FAQ)

Q: Can SS8P2L-M3/86A be used in automotive applications requiring AEC-Q101 qualification?

A: The SS8P2L-M3/86A does not carry explicit automotive grade or AEC-Q101 qualification in the provided specifications. For applications with automotive qualification requirements, use SS8P2LHM3_A/I or SS8P2LHM3_A/H.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel and Cut Tape & Digi-Reel® are packaging and delivery formats that do not affect component electrical or mechanical performance. Selection depends on assembly equipment compatibility and procurement workflow. Both formats contain identical components with the same electrical specifications.

Q: Are all three parts electrically interchangeable?

A: Yes. SS8P2LHM3_A/I, SS8P2L-M3/86A, and SS8P2LHM3_A/H are electrically interchangeable. All three maintain identical voltage ratings (20 V), current ratings (8 A), forward voltage characteristics (570 mV @ 8 A), and thermal operating range (-55°C to 150°C).

Q: Which substitute part should be selected for new production designs?

A: For new production designs, SS8P2LHM3_A/H is the recommended substitute. It maintains full automotive qualification (AEC-Q101), automotive grade classification, and identical electrical and mechanical parameters to the primary part SS8P2LHM3_A/I, with higher inventory availability.

Q: Does the base product number SS8P2 indicate these parts are from the same product family?

A: Yes. All three parts share the base product number SS8P2, confirming they belong to the same Schottky rectifier product family within the eSMP® series. Variations in the full part number designate packaging format and qualification status.

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

A: No. All three parts maintain identical operating temperature range (-55°C to 150°C), forward voltage characteristics (570 mV @ 8 A), reverse leakage current (200 µA @ 30 V), and capacitance (330 pF @ 4V, 1MHz). Performance is equivalent across all electrical parameters.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

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. All three parts carry this classification.
