Engineering Selection Recommendations

Parametric Equivalents (Direct Substitution):

SS8P3LHM3_A/H and SS8P3LHM3_A/I are parametric equivalents of the SS8P3L-M3/86A. Both parts maintain identical electrical specifications (30 V, 8 A, 570 mV forward voltage, fast recovery speed, and reverse leakage characteristics) and mechanical compatibility (TO-277A SMPC package). Both are manufactured by Vishay General Semiconductor - Diodes Division within the eSMP® series. The primary distinction is automotive-grade qualification (AEC-Q101) for both substitute parts, whereas the main part carries standard grade classification. All three parts are ROHS3 compliant with MSL 1 rating and Active product status.

Manufacturer Recommended Alternative (Current-Limited Application):

PMEG030V030EPDZ, manufactured by Nexperia USA Inc., is designated as a manufacturer-recommended substitute. This part maintains the 30 V reverse voltage rating and fast recovery speed characteristic. However, the average rectified current is rated at 3 A, which is lower than the 8 A specification of the main part. The forward voltage at rated current is 450 mV @ 3 A, representing improved performance at its rated current level. The PMEG030V030EPDZ carries automotive-grade qualification (AEC-Q101) and is ROHS3 compliant with MSL 1 rating. This part is suitable for applications where current requirements do not exceed 3 A and where the improved thermal characteristics (maximum junction temperature of 175°C versus 150°C) provide design margin.

All substitute parts maintain compliance with ROHS3, REACH Unaffected status, and ECCN EAR99 classification.

Frequently Asked Questions (FAQ)

Q: Can SS8P3LHM3_A/H and SS8P3LHM3_A/I be used interchangeably with SS8P3L-M3/86A?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (30 V, 8 A, 570 mV forward voltage) and mechanical specifications (TO-277A SMPC package). The primary difference is automotive-grade qualification (AEC-Q101) for the substitute parts. All three parts are Active status, ROHS3 compliant, and MSL 1 rated.

Q: What is the key limitation of PMEG030V030EPDZ as a substitute?

A: The PMEG030V030EPDZ is rated for 3 A average rectified current, compared to 8 A for the main part. This part is suitable only for applications where current requirements do not exceed 3 A. The 30 V reverse voltage rating and fast recovery speed are maintained.

Q: Are all substitute parts available in the same package?

A: SS8P3LHM3_A/H and SS8P3LHM3_A/I are supplied in TO-277A (SMPC) package, identical to the main part. PMEG030V030EPDZ is supplied in CFP15 package designation but maintains the same TO-277, 3-PowerDFN physical form factor and surface mount mounting type.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant, REACH Unaffected, and carry ECCN EAR99 classification. All maintain MSL 1 (Unlimited) moisture sensitivity level and Active product status.

Q: What is the difference between standard grade and automotive grade for these diodes?

A: The main part SS8P3L-M3/86A carries standard grade classification. Substitute parts SS8P3LHM3_A/H and SS8P3LHM3_A/I carry automotive grade with AEC-Q101 qualification. PMEG030V030EPDZ also carries automotive grade with AEC-Q101 qualification. Automotive-grade parts meet additional qualification and reliability standards for automotive applications.

Q: Can PMEG030V030EPDZ be used in a circuit designed for 8 A operation?

A: No. PMEG030V030EPDZ is rated for maximum 3 A average rectified current. Using this part in an 8 A circuit would exceed its current rating and result in device failure or degraded performance.

Q: Are there differences in reverse leakage current between the parts?

A: SS8P3L-M3/86A, SS8P3LHM3_A/H, and SS8P3LHM3_A/I all specify 200 µA @ 30 V reverse leakage. PMEG030V030EPDZ specifies 150 µA @ 30 V, representing lower leakage current at the same voltage rating.

Q: What is the operating temperature range for each part?

A: SS8P3L-M3/86A, SS8P3LHM3_A/H, and SS8P3LHM3_A/I specify -55°C to 150°C junction temperature range. PMEG030V030EPDZ specifies a maximum junction temperature of 175°C, providing extended high-temperature operation capability.
