SS8P3L-E3/86A Equivalent & Substitute Parts

Part Overview

The SS8P3L-E3/86A is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 30 V DC reverse voltage and 8 A average rectified current in a surface mount TO-277A (SMPC) package. This component is part of the eSMP® series and is classified as obsolete. Due to its obsolete status, equivalent substitute parts with active product status are available to maintain design continuity and ensure supply chain reliability for new production and ongoing support applications.

Substitute Part Grouping Explanation

Substitute parts for the SS8P3L-E3/86A are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Vishay eSMP® Series): Parts SS8P3L-M3/86A, SS8P3L-M3/87A, SS8P3LHM3_A/H, and SS8P3LHM3_A/I maintain identical electrical specifications across all critical parameters: 30 V reverse voltage, 8 A average rectified current, 570 mV forward voltage at 8 A, fast recovery speed, and 200 µA reverse leakage current. All share the same TO-277A (SMPC) package and surface mount configuration. These parts differ only in product status (active versus obsolete), manufacturing date codes, and in the case of SS8P3LHM3_A/H and SS8P3LHM3_A/I, automotive-grade qualification (AEC-Q101). The parametric equivalents provide direct functional replacement with no circuit redesign required.

Manufacturer Recommended Substitute (Nexperia): The PMEG030V030EPDZ from Nexperia USA Inc. is listed as a manufacturer-recommended alternative. While it maintains the same 30 V reverse voltage rating and fast recovery speed characteristics, it differs in current rating (3 A versus 8 A) and forward voltage specification (450 mV @ 3 A). This part is suitable only for applications where the 8 A current requirement can be reduced to 3 A or lower. The PMEG030V030EPDZ carries automotive-grade qualification (AEC-Q101) and operates to a maximum junction temperature of 175°C.

Substitution logic is based strictly on the following parameters: reverse voltage rating, average rectified current capacity, forward voltage characteristics, recovery speed, reverse leakage current, package type, and mounting configuration.

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification):

The Vishay parametric equivalents SS8P3L-M3/86A, SS8P3L-M3/87A, SS8P3LHM3_A/H, and SS8P3LHM3_A/I are suitable for direct substitution in applications currently using the SS8P3L-E3/86A. All four parts maintain identical electrical performance across reverse voltage, forward voltage, current rating, and recovery speed specifications. The primary distinction is product status: SS8P3L-M3/86A and SS8P3L-M3/87A are standard industrial-grade parts with active status, while SS8P3LHM3_A/H and SS8P3LHM3_A/I are automotive-grade parts qualified to AEC-Q101. Selection between these options depends on application requirements and supply availability.

For Automotive Applications:

If the application requires automotive-grade qualification, SS8P3LHM3_A/H or SS8P3LHM3_A/I are the appropriate selections, as both carry AEC-Q101 qualification and active product status. These parts are functionally identical to the industrial-grade alternatives and provide the same electrical performance with automotive reliability assurance.

For Current-Reduced Applications:

The PMEG030V030EPDZ from Nexperia is applicable only in applications where the required average rectified current is 3 A or lower. This part is not suitable as a direct replacement for the 8 A rated SS8P3L-E3/86A in circuits requiring the full 8 A capacity. The PMEG030V030EPDZ carries AEC-Q101 automotive qualification and offers improved reverse leakage characteristics (150 µA versus 200 µA) and a higher maximum junction temperature rating (175°C).

Frequently Asked Questions (FAQ)

Q: Can the SS8P3L-M3/86A be used as a direct replacement for the obsolete SS8P3L-E3/86A?

A: Yes. The SS8P3L-M3/86A is a parametric equivalent with identical electrical specifications: 30 V reverse voltage, 8 A average rectified current, 570 mV forward voltage at 8 A, and fast recovery speed characteristics. Both parts use the same TO-277A (SMPC) surface mount package. No circuit modification is required.

Q: What is the difference between SS8P3L-M3/86A and SS8P3L-M3/87A?

A: Both parts are parametric equivalents with identical electrical specifications and package configuration. The difference is in the manufacturing date code designation (86A versus 87A). Both are active products suitable for new designs and production applications.

Q: Are SS8P3LHM3_A/H and SS8P3LHM3_A/I suitable for automotive applications?

A: Yes. Both parts carry automotive-grade qualification (AEC-Q101) and are suitable for automotive applications. They maintain the same electrical specifications as the industrial-grade Vishay equivalents while providing automotive reliability assurance.

Q: Can the PMEG030V030EPDZ replace the SS8P3L-E3/86A in all applications?

A: No. The PMEG030V030EPDZ is rated for 3 A average rectified current, compared to the 8 A rating of the SS8P3L-E3/86A. This part is suitable only for applications where the required current is 3 A or lower. For applications requiring the full 8 A capacity, use one of the Vishay parametric equivalents.

Q: What are the key parameters that determine substitution compatibility?

A: The critical parameters for substitution are: reverse voltage rating (30 V), average rectified current capacity (8 A for direct replacement), forward voltage characteristics (570 mV @ 8 A), recovery speed (fast recovery ≤ 500ns), package type (TO-277A SMPC), and mounting configuration (surface mount). All parametric equivalents maintain these specifications.

Q: Is the PMEG030V030EPDZ from Nexperia automotive-qualified?

A: Yes. The PMEG030V030EPDZ carries AEC-Q101 automotive qualification. However, its 3 A current rating limits its application scope compared to the 8 A rated Vishay parts.

Q: What is the difference in reverse leakage current between the substitute parts?

A: The Vishay parts (SS8P3L-E3/86A, SS8P3L-M3/86A, SS8P3L-M3/87A, SS8P3LHM3_A/H, SS8P3LHM3_A/I) specify 200 µA reverse leakage at 30 V. The PMEG030V030EPDZ specifies 150 µA reverse leakage at 30 V, representing lower leakage characteristics.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the main part SS8P3L-E3/86A, are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the maximum junction temperature for each part?

A: The Vishay parts (SS8P3L-E3/86A, SS8P3L-M3/86A, SS8P3L-M3/87A, SS8P3LHM3_A/H, SS8P3LHM3_A/I) operate to a maximum junction temperature of 150°C. The PMEG030V030EPDZ operates to a maximum junction temperature of 175°C.
