SS2P2L-E3/85A Equivalent & Substitute Parts

Part Overview

The SS2P2L-E3/85A is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, part of the eSMP® series. This component is rated for 20 V DC reverse voltage with 2 A average rectified current in a DO-220AA surface mount package. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications for continued circuit functionality.

Substitute Part Grouping Explanation

Substitution of the SS2P2L-E3/85A is determined by strict equivalence across the following critical parameters:

Voltage - DC Reverse (Vr) (Max): 20 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 500 mV @ 2 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 200 µA @ 20 V
Package / Case: DO-220AA (SMP)
Operating Temperature - Junction: -55°C ~ 150°C
Technology: Schottky

Engineering Selection Recommendations

All three substitute parts (SS2P2L-M3/85A, SS2P2L-M3/84A, and SS2P2LHM3/84A) provide direct electrical and mechanical equivalence to the obsolete SS2P2L-E3/85A. Selection among these alternatives is determined by application requirements and supply chain considerations:

SS2P2L-M3/85A is the primary direct substitute, maintaining identical part number structure with active product status and Tape & Reel packaging format.

SS2P2L-M3/84A provides parametric equivalence with Cut Tape packaging and the highest available inventory level, suitable for applications where packaging format flexibility is acceptable.

SS2P2LHM3/84A is specified for applications requiring automotive-grade reliability and AEC-Q101 qualification. This variant is appropriate for automotive and mission-critical applications where enhanced qualification standards are mandated.

All substitutes maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical thermal operating range (-55°C to 150°C junction temperature).

Frequently Asked Questions (FAQ)

Q: Can SS2P2L-M3/85A directly replace SS2P2L-E3/85A in existing designs?

A: Yes. SS2P2L-M3/85A maintains identical electrical specifications (20 V reverse voltage, 2 A average rectified current, 500 mV forward voltage at 2 A) and mechanical configuration (DO-220AA surface mount package). The primary difference is product status (Active versus Obsolete) and packaging format (Tape & Reel).

Q: What is the difference between SS2P2L-M3/84A and SS2P2L-M3/85A?

A: Both parts are parametrically equivalent with identical electrical performance. The difference is packaging format: SS2P2L-M3/85A is supplied in Tape & Reel format, while SS2P2L-M3/84A is available in Cut Tape format. Electrical and mechanical specifications are identical.

Q: When should SS2P2LHM3/84A be selected instead of other substitutes?

A: SS2P2LHM3/84A is specified for applications requiring automotive-grade components with AEC-Q101 qualification. This variant is appropriate for automotive circuits, industrial control systems, and other applications where enhanced reliability certification is required. Electrical performance is identical to other substitutes.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All substitute parts (SS2P2L-M3/85A, SS2P2L-M3/84A, and SS2P2LHM3/84A) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only supply chain logistics and handling procedures. Electrical specifications, thermal performance, and mechanical compatibility remain identical across all packaging formats.

Q: Can these diodes be used in circuits operating at the full 20 V and 2 A ratings simultaneously?

A: All substitute parts are rated for 20 V DC reverse voltage and 2 A average rectified current. Circuit design must ensure that actual operating conditions do not exceed these maximum ratings.
