Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS5P3HM3_A/I are identified based on strict electrical and mechanical parameter matching within the Schottky rectifier diode category. The substitution logic is structured as follows:

Parametric Equivalent Classification: Parts classified as parametric equivalents maintain identical or functionally equivalent specifications across all critical electrical parameters: 30 V DC reverse voltage rating, 5 A average rectified current, fast recovery speed characteristics, surface mount technology, and TO-277 package designation. These parts are interchangeable at the circuit design level without modification to board layout or thermal management.

Manufacturer Recommended Classification: Parts designated as manufacturer recommended substitutes meet the primary electrical requirements (30 V reverse voltage, fast recovery Schottky technology, surface mount configuration) but may exhibit variations in secondary parameters such as average rectified current rating, forward voltage characteristics, or junction temperature limits. These parts require engineering evaluation for specific application contexts.

Key Parameters Governing Substitution:

• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Technology: Schottky rectifier
• Mounting Type: Surface Mount
• Package / Case: TO-277 or compatible 3-PowerDFN
• Speed Classification: Fast Recovery ≤ 500ns
• Automotive Grade and AEC-Q101 Qualification (where applicable)
• RoHS3 Compliance

Parameter Comparison

Engineering Selection Recommendations

SS5P3-M3/86A (Parametric Equivalent): The SS5P3-M3/86A is a parametric equivalent to the SS5P3HM3_A/I, manufactured by Vishay General Semiconductor - Diodes Division. Both parts share identical electrical specifications: 30 V reverse voltage, 5 A average rectified current, 520 mV forward voltage at 5 A, and fast recovery characteristics. Both are surface mount devices in TO-277A (SMPC) package configuration with -55°C to 150°C junction temperature range and ROHS3 compliance. The SS5P3-M3/86A is designated within the eSMP® series and carries higher inventory availability (12,200 pcs). This part is suitable for direct substitution in applications where the SS5P3HM3_A/I is specified, with no circuit redesign required.

PMEG030V030EPDZ (Manufacturer Recommended Substitute): The PMEG030V030EPDZ is manufactured by Nexperia USA Inc. and meets the primary electrical classification criteria: 30 V reverse voltage, Schottky technology, fast recovery speed, and surface mount configuration. This part carries AEC-Q101 automotive qualification and ROHS3 compliance, matching the compliance profile of the main part. However, the PMEG030V030EPDZ is rated for 3 A average rectified current, compared to the 5 A rating of the SS5P3HM3_A/I. The forward voltage is 450 mV at 3 A, and reverse leakage is 150 µA at 30 V. The maximum junction temperature is 175°C, exceeding the 150°C limit of the main part. The supplier device package is designated CFP15 rather than TO-277A (SMPC), though both are classified as TO-277, 3-PowerDFN case types. This part is suitable for applications where current requirements do not exceed 3 A and where the higher temperature rating provides operational margin.

Frequently Asked Questions (FAQ)

Q: Can the SS5P3-M3/86A be used as a direct replacement for the SS5P3HM3_A/I?

A: Yes. The SS5P3-M3/86A is a parametric equivalent with identical electrical specifications across all critical parameters: 30 V reverse voltage, 5 A average rectified current, 520 mV forward voltage at 5 A, fast recovery speed, and -55°C to 150°C junction temperature range. Both parts are surface mount Schottky diodes in TO-277A (SMPC) package configuration. No circuit modification is required for substitution.

Q: What are the limitations of using the PMEG030V030EPDZ as a substitute?

A: The PMEG030V030EPDZ has a reduced average rectified current rating of 3 A compared to the 5 A rating of the SS5P3HM3_A/I. This part is suitable only for applications where the circuit current requirement does not exceed 3 A. The supplier device package designation (CFP15) differs from the TO-277A (SMPC) designation of the main part, though both are classified within the TO-277, 3-PowerDFN case family. Verification of physical footprint compatibility with the PCB layout is required before substitution.

Q: Are all substitute parts automotive qualified?

A: The SS5P3HM3_A/I and PMEG030V030EPDZ both carry AEC-Q101 automotive qualification and Automotive grade designation. The SS5P3-M3/86A does not specify automotive grade or AEC-Q101 qualification in the provided parameters. For applications requiring automotive qualification, the PMEG030V030EPDZ is the only confirmed substitute with this certification.

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

A: The SS5P3HM3_A/I and SS5P3-M3/86A both specify 250 µA reverse leakage at 30 V. The PMEG030V030EPDZ specifies 150 µA reverse leakage at 30 V, representing lower leakage characteristics. Lower reverse leakage may provide improved performance in low-current or high-impedance circuit applications.

Q: Are there package compatibility considerations for substitution?

A: All three parts are designated as surface mount devices in TO-277, 3-PowerDFN package classification. The SS5P3HM3_A/I and SS5P3-M3/86A use the TO-277A (SMPC) supplier device package, while the PMEG030V030EPDZ uses the CFP15 supplier device package. Although both are classified within the same case family, physical footprint dimensions may differ. PCB layout verification is required before substituting the PMEG030V030EPDZ.

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

A: The SS5P3HM3_A/I and SS5P3-M3/86A both specify -55°C to 150°C operating junction temperature range. The PMEG030V030EPDZ specifies a maximum junction temperature of 175°C, providing an additional 25°C thermal margin. This higher temperature rating may be advantageous in high-temperature operating environments.

Q: Are all parts RoHS compliant?

A: Yes. All three parts—SS5P3HM3_A/I, SS5P3-M3/86A, and PMEG030V030EPDZ—are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic component manufacturing and use.
