Substitute Part Grouping Explanation

Substitute parts for the PMEG045T150EPDAZ are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalent Classification: Parts that maintain identical electrical specifications across all critical parameters including reverse voltage, rectified current, forward voltage drop, recovery time, leakage current, and capacitance. These parts differ only in packaging format (Cut Tape versus Tape & Reel) and are directly interchangeable at the circuit level.

Similar Classification: Parts that operate within compatible voltage and current ranges but exhibit variations in one or more secondary parameters such as reverse leakage current, operating temperature range, or reverse recovery time specifications. These parts satisfy the primary functional requirements but require verification of application-specific constraints.

The following parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 45 V
Current - Average Rectified (Io): Must equal or exceed 15 A
Voltage - Forward (Vf) (Max) @ If: Must not exceed 550 mV at rated current
Package / Case: Must be TO-277, 3-PowerDFN surface mount
Technology: Schottky rectifier diode
Mounting Type: Surface Mount

Engineering Selection Recommendations

PMEG045T150EPDZ (Parametric Equivalent): This part is a direct electrical equivalent to the PMEG045T150EPDAZ with identical performance across all specified parameters. The only difference is packaging format: PMEG045T150EPDZ is supplied in Tape & Reel (TR) format while the main part is available in Cut Tape (CT) & Digi-Reel® format. Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance. Selection between these two parts depends on procurement and assembly requirements related to packaging format. No circuit-level modifications are required for substitution.

FSV2050V (Similar): This onsemi part operates at higher voltage (50 V) and current (20 A) ratings compared to the PMEG045T150EPDAZ specifications. The forward voltage drop remains equivalent at 550 mV. The FSV2050V exhibits higher reverse leakage current (320 µA @ 50 V versus 100 µA @ 45 V) and operates within a lower maximum junction temperature range (-55°C ~ 150°C versus 175°C). The FSV2050V does not carry specified automotive grade or AEC-Q101 qualification. This part is suitable for applications where higher voltage and current margins are acceptable and automotive qualification is not required. Applications requiring AEC-Q101 certification or maximum junction temperature operation above 150°C must use the PMEG045T150EPDAZ or PMEG045T150EPDZ.
