Substitute Part Grouping Explanation

Substitute parts for the PMEG045T100EPDZ are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalent: PMEG045T100EPDAZ matches all critical electrical specifications and physical packaging requirements. This part maintains identical voltage rating (45 V), current rating (14 A), forward voltage characteristics (480 mV @ 10 A), reverse recovery time (40 ns), and reverse leakage current (80 µA @ 45 V). The package designation (TO-277, 3-PowerDFN / CFP15) is identical, enabling direct mechanical and electrical substitution without circuit redesign.

Similar Manufacturer Part: FSV2050V from onsemi provides functional equivalence with relaxed electrical parameters. This part exceeds the voltage rating (50 V vs. 45 V) and current capacity (20 A vs. 14 A), supporting operation in circuits designed for the PMEG045T100EPDZ. However, forward voltage (550 mV @ 20 A) and reverse leakage current (320 µA @ 50 V) differ from the original specification. The package remains compatible (TO-277, 3-PowerDFN). FSV2050V carries Active product status, ensuring continued availability.

Substitution eligibility is determined by:

• Voltage rating equal to or greater than 45 V
• Current rating equal to or greater than 14 A
• Surface mount package compatibility (TO-277, 3-PowerDFN)
• Schottky diode technology
• Fast recovery characteristics (≤ 500 ns)

Parameter Comparison

Engineering Selection Recommendations

PMEG045T100EPDAZ is the primary substitute for direct replacement applications. This part is electrically and mechanically identical to the PMEG045T100EPDZ, maintaining the same voltage rating, current capacity, forward voltage characteristics, and reverse recovery performance. Both parts carry Automotive grade classification and AEC-Q101 qualification, ensuring compliance with automotive reliability standards. The PMEG045T100EPDAZ is suitable for applications where the original specification must be preserved without modification.

FSV2050V serves as an alternative for applications where higher voltage and current margins are acceptable. The elevated voltage rating (50 V) and current capacity (20 A) provide design headroom in circuits operating below the original part's maximum ratings. However, the higher forward voltage drop (550 mV @ 20 A) and increased reverse leakage current (320 µA @ 50 V) result in greater power dissipation and heat generation compared to the PMEG045T100EPDZ. The FSV2050V carries Active product status, ensuring long-term availability. The reduced maximum junction temperature (150°C vs. 175°C) must be evaluated against thermal design requirements. Automotive grade and AEC-Q101 qualification are not specified for this part; compliance verification is required for automotive applications.

Selection between these substitutes depends on application requirements: use PMEG045T100EPDAZ for specification-critical applications; use FSV2050V where higher ratings and extended availability justify the performance trade-offs.

Frequently Asked Questions (FAQ)

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

A: Yes. The PMEG045T100EPDAZ is a parametric equivalent with identical electrical specifications and package configuration. No circuit modifications are required.

Q: What are the key differences between PMEG045T100EPDZ and FSV2050V?

A: FSV2050V has higher voltage (50 V vs. 45 V) and current ratings (20 A vs. 14 A), but exhibits higher forward voltage drop (550 mV @ 20 A vs. 480 mV @ 10 A) and reverse leakage current (320 µA @ 50 V vs. 80 µA @ 45 V). Maximum junction temperature is lower (150°C vs. 175°C). Both use compatible TO-277, 3-PowerDFN packages.

Q: Is FSV2050V suitable for automotive applications?

A: FSV2050V does not carry specified Automotive grade or AEC-Q101 qualification. Compliance verification with automotive standards is required before use in automotive circuits.

Q: Why is the PMEG045T100EPDZ marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. Nexperia recommends using alternative parts for new designs. However, the part remains available for legacy system support and maintenance.

Q: Can FSV2050V be used in high-temperature applications?

A: FSV2050V has a maximum junction temperature of 150°C, compared to 175°C for the PMEG045T100EPDZ. Applications requiring operation above 150°C require thermal analysis or alternative parts.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. PMEG045T100EPDZ, PMEG045T100EPDAZ, and FSV2050V are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the impact of higher reverse leakage current in FSV2050V?

A: Higher reverse leakage current (320 µA @ 50 V vs. 80 µA @ 45 V) increases standby power consumption and heat dissipation. This must be evaluated in low-power or battery-operated applications.

Q: Are the packages physically identical?

A: Yes. PMEG045T100EPDZ, PMEG045T100EPDAZ, and FSV2050V all use TO-277, 3-PowerDFN surface mount packages, enabling direct PCB footprint compatibility.
