SS2P3-E3/85A Equivalent & Substitute Parts

Part Overview

The SS2P3-E3/85A is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 30 V DC reverse voltage and 2 A average rectified current in a DO-220AA surface mount package. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within the same application category.

Substitute Part Grouping Explanation

Substitution eligibility for the SS2P3-E3/85A is determined by matching the following critical parameters: Schottky technology classification, 30 V maximum reverse voltage rating, 2 A average rectified current capacity, fast recovery speed characteristic (≤ 500ns at > 200mA), surface mount mounting type, and operating temperature range of -55°C to 150°C junction temperature.

Substitute parts are grouped into two categories:

Category 1: Vishay eSMP® Series (Same Manufacturer, Same Package) Parts SS2P3-M3/85A, SS2P3-M3/84A, SS2P3HM3/85A, and SS2P3HM3/84A maintain identical electrical specifications and the DO-220AA package footprint. These parts differ in product status (active versus obsolete), packaging format (tape & reel or cut tape), and in the case of SS2P3HM3 variants, automotive-grade qualification with AEC-Q101 certification.

Category 2: Cross-Manufacturer Alternative (Nexperia) Part PMEG3020BER,115 provides functional equivalence with matching voltage and current ratings but utilizes a different package format (SOD-123W) and exhibits minor variations in forward voltage (520 mV versus 550 mV) and reverse leakage current (50 µA versus 150 µA).

Engineering Selection Recommendations

For Direct Replacement (Same Package, Same Manufacturer): SS2P3-M3/85A and SS2P3HM3/85A are the primary substitutes, both maintaining the DO-220AA package and identical electrical specifications. SS2P3-M3/85A is an active product in the standard eSMP® series. SS2P3HM3/85A provides the same functionality with automotive-grade qualification (AEC-Q101), suitable for applications requiring automotive compliance.

For Parametric Equivalence with Packaging Flexibility: SS2P3-M3/84A and SS2P3HM3/84A are parametrically equivalent alternatives available in cut tape and tape & reel formats. These parts maintain all critical electrical parameters and the DO-220AA package footprint.

For Cross-Manufacturer Substitution: PMEG3020BER,115 (Nexperia) provides functional equivalence with identical voltage and current ratings but requires PCB layout modification due to the SOD-123W package format. This part exhibits improved reverse leakage characteristics (50 µA versus 150 µA) and marginally lower forward voltage (520 mV versus 550 mV), resulting in reduced power dissipation. All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can SS2P3-M3/85A directly replace SS2P3-E3/85A without PCB modification? A: Yes. SS2P3-M3/85A maintains identical electrical specifications and the DO-220AA package footprint, enabling direct substitution without PCB layout changes.

Q: What is the difference between SS2P3-M3/85A and SS2P3HM3/85A? A: Both parts are electrically identical with matching 30 V, 2 A ratings and DO-220AA packaging. SS2P3HM3/85A includes automotive-grade qualification (AEC-Q101) and is suitable for automotive applications. SS2P3-M3/85A is the standard industrial-grade variant.

Q: Can PMEG3020BER,115 be used as a substitute? A: PMEG3020BER,115 provides functional equivalence with matching voltage and current ratings but uses the SOD-123W package instead of DO-220AA. PCB layout modification is required. The part exhibits lower reverse leakage (50 µA) and forward voltage (520 mV), reducing power dissipation.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), matching the original SS2P3-E3/85A specifications.

Q: What packaging formats are available for Vishay eSMP® substitutes? A: Vishay eSMP® substitutes are available in tape & reel (TR) and cut tape (CT) formats. SS2P3-M3/85A and SS2P3HM3/85A are supplied in tape & reel. SS2P3-M3/84A is available in cut tape format.

Q: Does the automotive-grade variant (SS2P3HM3/85A) have different electrical performance? A: No. SS2P3HM3/85A maintains identical electrical specifications to the standard variant. The automotive designation indicates AEC-Q101 qualification and suitability for automotive applications, not performance differences.
