Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SS5P3-M3/86A are identified based on the following critical electrical and mechanical parameters:

Voltage Class Matching: The substitute part must maintain the same 30 V DC reverse voltage rating to ensure circuit protection and reliability in the intended application.

Package Compatibility: The substitute must use the TO-277 / 3-PowerDFN package family to ensure mechanical and thermal compatibility with existing PCB layouts and thermal management designs.

Technology Class: Both the main part and substitute are Schottky diodes, ensuring consistent switching characteristics and forward voltage behavior.

Current Rating Consideration: The substitute part may have a lower average rectified current rating (3 A versus 5 A) provided the application circuit does not exceed the substitute's current specification. This represents a derating scenario where the substitute is suitable for lower-current applications within the same voltage class.

Compliance Requirements: Both parts must maintain ROHS3 compliance and unlimited MSL rating to meet manufacturing and storage requirements.

The PMEG030V030EPDZ from Nexperia USA Inc. meets these substitution criteria with matching voltage and package specifications, though with reduced current capacity and enhanced automotive qualification (AEC-Q101).

Parameter Comparison

Engineering Selection Recommendations

Primary Application Suitability: The SS5P3-M3/86A is the preferred selection for applications requiring the full 5 A average rectified current capacity at 30 V reverse voltage. Both parts are active products with ROHS3 compliance and unlimited MSL rating, ensuring long-term availability and manufacturing compatibility.

Substitute Selection Criteria: The PMEG030V030EPDZ is suitable as a substitute only in applications where the circuit current requirement does not exceed 3 A. The substitute offers improved reverse leakage characteristics (150 µA versus 250 µA at 30 V) and a higher maximum junction temperature rating (175°C versus 150°C). The substitute carries AEC-Q101 automotive qualification, making it appropriate for automotive-grade applications.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across manufacturing regions. Both parts carry unlimited moisture sensitivity level (MSL 1), eliminating moisture-related handling restrictions.

Thermal Performance: The PMEG030V030EPDZ supports a higher maximum junction temperature (175°C), providing additional thermal margin in high-temperature operating environments. The SS5P3-M3/86A operates to 150°C maximum junction temperature.

Forward Voltage Consideration: At rated current, the PMEG030V030EPDZ exhibits lower forward voltage (450 mV @ 3 A) compared to the SS5P3-M3/86A (520 mV @ 5 A), resulting in reduced power dissipation in current-limited applications.

Frequently Asked Questions (FAQ)

Q: Can the PMEG030V030EPDZ replace the SS5P3-M3/86A in all applications?

A: The PMEG030V030EPDZ is a suitable substitute only for applications where the average rectified current does not exceed 3 A. If the circuit requires the full 5 A capacity of the SS5P3-M3/86A, the substitute is not appropriate. Both parts share the same 30 V voltage rating and TO-277 package, ensuring mechanical and thermal compatibility within the current derating constraint.

Q: What are the key differences between these two diodes?

A: The primary difference is current rating: SS5P3-M3/86A is rated for 5 A while PMEG030V030EPDZ is rated for 3 A. Secondary differences include forward voltage (520 mV versus 450 mV at rated current), reverse leakage (250 µA versus 150 µA), maximum junction temperature (150°C versus 175°C), and automotive qualification (AEC-Q101 for the Nexperia part only).

Q: Are both parts available in the same package?

A: Yes. Both the SS5P3-M3/86A and PMEG030V030EPDZ use the TO-277 / 3-PowerDFN surface mount package, ensuring identical PCB footprint and thermal interface compatibility.

Q: Do these parts have the same voltage rating?

A: Yes. Both parts are rated for 30 V DC reverse voltage, ensuring equivalent circuit protection and voltage class performance.

Q: Which part should I select for automotive applications?

A: The PMEG030V030EPDZ carries AEC-Q101 automotive qualification and is suitable for automotive-grade applications. The SS5P3-M3/86A does not specify automotive qualification. If automotive qualification is required and the circuit current does not exceed 3 A, the PMEG030V030EPDZ is the appropriate selection.

Q: What is the impact of the lower current rating on circuit design?

A: The PMEG030V030EPDZ is limited to 3 A average rectified current. If your circuit requires higher current capacity, the SS5P3-M3/86A must be used. If your circuit operates below 3 A, the PMEG030V030EPDZ is suitable and offers improved reverse leakage and thermal performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the SS5P3-M3/86A and PMEG030V030EPDZ are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), meeting current manufacturing and environmental regulations.

Q: What is the reverse recovery time difference?

A: The PMEG030V030EPDZ specifies a reverse recovery time of 12 ns. The SS5P3-M3/86A does not provide a specific reverse recovery time specification, only a fast recovery classification (≤ 500 ns). Both parts meet fast recovery requirements for switching applications.
