Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS8P3LHM3_A/H is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 570 mV @ 8 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 200 µA @ 30 V
• Capacitance @ Vr, F: 330pF @ 4V, 1MHz

Mechanical Parameters (Must Match):

• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Supplier Device Package: TO-277A (SMPC)

Compliance Parameters (Must Match):

• Technology: Schottky
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts that match all electrical, mechanical, and compliance parameters. These parts are direct functional replacements with identical performance characteristics.

Manufacturer Recommended Equivalent: Parts that meet the same voltage and package specifications but differ in current rating or other secondary parameters. These parts require application-level verification for current capacity compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents:

SS8P3L-M3/86A and SS8P3LHM3_A/I are parametric equivalents to SS8P3LHM3_A/H. All three parts share identical electrical specifications (30 V, 8 A, 570 mV forward voltage, 200 µA reverse leakage, 330pF capacitance), identical package configuration (TO-277A SMPC), and identical operating temperature range (-55 to 150°C). Both SS8P3LHM3_A/H and SS8P3LHM3_A/I carry automotive grade designation and AEC-Q101 qualification. SS8P3L-M3/86A does not specify automotive grade or AEC-Q101 qualification in the provided data. All three parts are ROHS3 compliant with MSL 1 rating and active product status.

Manufacturer Recommended Equivalent:

PMEG030V030EPDZ (Nexperia USA Inc.) is listed as a manufacturer-recommended equivalent. This part maintains the 30 V reverse voltage rating and automotive grade with AEC-Q101 qualification. However, the current rating is 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. The reverse leakage is 150 µA @ 30 V (lower than the main part). Capacitance is 495pF @ 1V, 1MHz. The maximum junction temperature is 175°C, exceeding the main part's 150°C maximum. The supplier device package is CFP15, which differs from the TO-277A (SMPC) package of the main part. PMEG030V030EPDZ is ROHS3 compliant with MSL 1 rating and active product status.

Selection Criteria:

For applications requiring full 8 A current capacity with identical electrical and thermal characteristics, select SS8P3L-M3/86A or SS8P3LHM3_A/I. Both maintain complete parametric equivalence and automotive qualification.

For applications with current requirements of 3 A or less, PMEG030V030EPDZ is suitable. This part offers lower forward voltage drop and lower reverse leakage, with extended maximum junction temperature capability. Package differences must be evaluated for PCB layout compatibility.

All substitute parts maintain ROHS3 compliance, automotive grade qualification (where specified), and active production status.

Frequently Asked Questions (FAQ)

Q: Can SS8P3L-M3/86A be used as a direct replacement for SS8P3LHM3_A/H?

A: Yes. SS8P3L-M3/86A is a parametric equivalent with identical electrical specifications (30 V, 8 A, 570 mV forward voltage), identical package (TO-277A SMPC), and identical operating temperature range (-55 to 150°C). Both parts are ROHS3 compliant with MSL 1 rating and active product status. The primary difference is that SS8P3L-M3/86A does not specify automotive grade or AEC-Q101 qualification in the provided data.

Q: What is the difference between SS8P3LHM3_A/H and SS8P3LHM3_A/I?

A: Both parts are parametric equivalents with identical electrical specifications, package configuration, and operating temperature range. Both carry automotive grade designation and AEC-Q101 qualification. The suffix difference (_A/H versus _A/I) indicates different manufacturing date codes or tape reel configurations. Both are ROHS3 compliant with MSL 1 rating and active product status.

Q: Can PMEG030V030EPDZ replace SS8P3LHM3_A/H in all applications?

A: The primary electrical difference is current rating: SS8P3LHM3_A/H is rated for 8 A, while PMEG030V030EPDZ is rated for 3 A. Forward voltage at rated current differs: 570 mV @ 8 A versus 450 mV @ 3 A. Reverse leakage is lower in PMEG030V030EPDZ (150 µA @ 30 V versus 200 µA @ 30 V). Capacitance differs: 330pF @ 4V, 1MHz versus 495pF @ 1V, 1MHz. Both maintain 30 V reverse voltage rating and fast recovery speed characteristics.

Q: Are all parts RoHS compliant?

A: Yes. All four parts (SS8P3LHM3_A/H, SS8P3L-M3/86A, SS8P3LHM3_A/I, and PMEG030V030EPDZ) are ROHS3 compliant.
