Engineering Selection Recommendations

SS10P5HM3_A/H (Parametric Equivalent)

The SS10P5HM3_A/H is a parametric equivalent to the SS10P5HM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, including 50 V reverse voltage, 7 A average rectified current, 670 mV forward voltage at 7 A, and 150 µA reverse leakage current at 50 V. Both devices are AEC-Q101 qualified automotive-grade components with identical operating temperature ranges (-55°C to 150°C junction temperature) and package configurations (TO-277A SMPC). The SS10P5HM3_A/H is a direct substitute requiring no circuit modifications. This part is suitable for applications where the original part number is unavailable or where inventory sourcing from alternative tape and reel batches is required.

FSV2050V (Manufacturer Recommended Substitute)

The FSV2050V, manufactured by onsemi, meets the mandatory alignment parameters of 50 V reverse voltage, fast recovery Schottky technology, surface mount TO-277 package, and -55°C to 150°C operating temperature range. The FSV2050V provides a higher current rating of 20 A compared to the 7 A rating of the SS10P5HM3_A/I, enabling use in higher-current applications. The forward voltage is lower at 550 mV @ 20 A, resulting in reduced power dissipation. Reverse leakage current is higher at 320 µA @ 50 V. The FSV2050V is ROHS3 compliant and maintains active product status. This part is suitable for applications where increased current capacity is beneficial and where the higher reverse leakage current is acceptable within circuit design margins.

PMEG045T050EPDZ (Manufacturer Recommended Substitute)

The PMEG045T050EPDZ, manufactured by Nexperia USA Inc., is an automotive-grade AEC-Q101 qualified Schottky rectifier with 45 V reverse voltage, 5 A average rectified current, and fast recovery characteristics. The reverse voltage rating is 5 V lower than the SS10P5HM3_A/I, limiting use to applications with maximum reverse voltages not exceeding 45 V. The current rating is 2 A lower at 5 A. The forward voltage is significantly lower at 465 mV @ 5 A, providing improved efficiency in lower-current circuits. Reverse leakage current is substantially lower at 44 µA @ 45 V. The operating temperature range extends to 175°C maximum junction temperature. The PMEG045T050EPDZ is ROHS3 compliant with active product status. This part is suitable for applications operating at 45 V or lower reverse voltages where reduced current requirements and lower leakage current are advantageous.

Frequently Asked Questions (FAQ)

Q: Can the SS10P5HM3_A/H be used as a direct replacement for the SS10P5HM3_A/I?

A: Yes. The SS10P5HM3_A/H is a parametric equivalent with identical electrical specifications and package configuration. No circuit modifications are required. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share the same base product number (SS10P5), AEC-Q101 qualification, and automotive grade classification.

Q: What are the key differences between the FSV2050V and the SS10P5HM3_A/I?

A: The FSV2050V has a higher current rating (20 A versus 7 A), lower forward voltage (550 mV @ 20 A versus 670 mV @ 7 A), and higher reverse leakage current (320 µA @ 50 V versus 150 µA @ 50 V). Both maintain 50 V reverse voltage rating and fast recovery characteristics. The FSV2050V is manufactured by onsemi rather than Vishay and does not carry automotive grade or AEC-Q101 qualification in the provided specifications.

Q: Can the PMEG045T050EPDZ replace the SS10P5HM3_A/I in all applications?

A: The PMEG045T050EPDZ has a lower reverse voltage rating (45 V versus 50 V) and lower current rating (5 A versus 7 A). It is suitable only for applications where the circuit operates at 45 V or lower reverse voltages and requires 5 A or less average rectified current. The PMEG045T050EPDZ offers lower forward voltage and reverse leakage current, making it advantageous for low-current, low-voltage applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The SS10P5HM3_A/I, SS10P5HM3_A/H, FSV2050V, and PMEG045T050EPDZ are all ROHS3 compliant. All parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the significance of the TO-277A (SMPC) versus TO-277-3 versus CFP15 package designations?

A: These designations identify the specific supplier device package format. The TO-277A (SMPC) is the Vishay tape and reel format for the SS10P5HM3_A/I and SS10P5HM3_A/H. The TO-277-3 is the onsemi format for the FSV2050V. The CFP15 is the Nexperia format for the PMEG045T050EPDZ. All three formats are compatible with the TO-277, 3-PowerDFN package footprint and are surface mount components. Verify PCB layout compatibility with the specific supplier device package before final component selection.

Q: Which substitute part has the lowest power dissipation?

A: The PMEG045T050EPDZ has the lowest forward voltage at 465 mV @ 5 A, resulting in the lowest power dissipation in applications operating at 5 A or lower. The FSV2050V has a forward voltage of 550 mV @ 20 A, which is lower than the SS10P5HM3_A/I at 670 mV @ 7 A when normalized to their respective current ratings.

Q: Are all substitute parts qualified for automotive applications?

A: The SS10P5HM3_A/I, SS10P5HM3_A/H, and PMEG045T050EPDZ are automotive-grade components with AEC-Q101 qualification. The FSV2050V does not carry automotive grade or AEC-Q101 qualification in the provided specifications. Verify automotive qualification requirements for your specific application before selecting the FSV2050V.

Q: What is the moisture sensitivity level (MSL) for all parts?

A: All parts—SS10P5HM3_A/I, SS10P5HM3_A/H, FSV2050V, and PMEG045T050EPDZ—have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
