Substitute Part Grouping Explanation

Substitution of the PMEG045T100EPDAZ is determined by alignment of critical electrical and mechanical parameters. The primary substitution criteria are:

Parametric Equivalents maintain identical or superior performance across all key specifications: reverse voltage rating (Vr), average rectified current (Io), forward voltage drop (Vf), reverse recovery time (trr), reverse leakage current, and package form factor. These parts are direct functional replacements with no circuit redesign required.

Similar Substitutes share the same package type and Schottky technology but may have variations in voltage rating, current capacity, or thermal characteristics. These parts are suitable when the application circuit can tolerate the parameter differences without performance degradation.

The following parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) must equal or exceed 45 V
Current - Average Rectified (Io) must equal or exceed 14 A
Package / Case must be TO-277, 3-PowerDFN (CFP15)
Technology must be Schottky
Mounting Type must be Surface Mount

Engineering Selection Recommendations

PMEG045T100EPDZ is the primary parametric equivalent. This part is manufactured by Nexperia USA Inc. and maintains identical electrical specifications, reverse recovery time, and reverse leakage characteristics as the main part. Both parts carry automotive-grade qualification (AEC-Q101) and are ROHS3 compliant. The PMEG045T100EPDZ is also classified as "Not For New Designs" but offers higher inventory availability (9541 pcs vs. 1370 pcs). This part is suitable for direct replacement in all applications where the PMEG045T100EPDAZ was originally specified.

FSV2050V is a similar substitute manufactured by onsemi with active product status. This part exceeds the voltage and current ratings of the main part (50 V, 20 A vs. 45 V, 14 A) and is suitable for applications where higher performance margins are acceptable. The forward voltage drop is higher (550 mV @ 20 A), and the maximum junction temperature is lower (150°C vs. 175°C). This part does not carry automotive-grade qualification or AEC-Q101 certification. FSV2050V is appropriate for non-automotive applications or where the reduced thermal rating does not constrain circuit operation.

MBR10U45L-TP is a similar substitute manufactured by Micro Commercial Co with active product status. This part matches the 45 V reverse voltage rating but has a reduced current capacity (10 A vs. 14 A). The forward voltage drop is lower (470 mV @ 10 A), and the maximum junction temperature is lower (150°C vs. 175°C). Reverse leakage current is significantly higher (500 µA @ 45 V vs. 80 µA @ 45 V). This part does not carry automotive-grade qualification or AEC-Q101 certification. MBR10U45L-TP is suitable only for applications where the 10 A current rating is sufficient and the higher leakage current is acceptable.

Frequently Asked Questions (FAQ)

Q: Can PMEG045T100EPDZ be used as a direct replacement for PMEG045T100EPDAZ?

A: Yes. PMEG045T100EPDZ is a parametric equivalent with identical electrical specifications, including reverse voltage (45 V), average rectified current (14 A), forward voltage drop (480 mV @ 10 A), reverse recovery time (40 ns), and reverse leakage current (80 µA @ 45 V). Both parts use the same TO-277, 3-PowerDFN package and carry AEC-Q101 automotive qualification. No circuit modifications are required.

Q: Is FSV2050V suitable for automotive applications?

A: FSV2050V does not carry automotive-grade qualification or AEC-Q101 certification. It is not recommended for automotive applications where these certifications are required by design specifications or regulatory standards.

Q: What is the current limitation of MBR10U45L-TP compared to the main part?

A: MBR10U45L-TP has a maximum average rectified current of 10 A, compared to 14 A for PMEG045T100EPDAZ. This part is suitable only for applications where the circuit current does not exceed 10 A.

Q: Why does FSV2050V have a lower maximum junction temperature?

A: FSV2050V has a maximum junction temperature of 150°C, compared to 175°C for PMEG045T100EPDAZ. Applications operating at elevated temperatures near or above 150°C may experience reduced performance or reliability with FSV2050V.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PMEG045T100EPDZ, FSV2050V, and MBR10U45L-TP are all ROHS3 compliant and suitable for use in applications with ROHS compliance requirements.

Q: What is the reverse leakage current difference between MBR10U45L-TP and the main part?

A: MBR10U45L-TP has a reverse leakage current of 500 µA @ 45 V, compared to 80 µA @ 45 V for PMEG045T100EPDAZ. The higher leakage current in MBR10U45L-TP may result in increased power dissipation in reverse bias conditions.

Q: Can FSV2050V be used in circuits designed for 45 V operation?

A: Yes. FSV2050V is rated for 50 V reverse voltage, which exceeds the 45 V requirement. However, the higher forward voltage drop (550 mV @ 20 A) and lower maximum junction temperature (150°C) must be evaluated against circuit performance and thermal constraints.

Q: Are PMEG045T100EPDAZ and PMEG045T100EPDZ interchangeable in terms of package footprint?

A: Yes. Both parts use the TO-277, 3-PowerDFN package with identical pin configuration and footprint. No PCB layout modifications are required for substitution.
