Substitute Part Grouping Explanation

Substitution of the MA2Z72000L is determined by the following critical parameters:

Voltage Rating: All substitute parts must maintain a DC reverse voltage rating of 40 V or greater to ensure safe operation within the original circuit design envelope.

Current Rating: The average rectified current (Io) defines the load-carrying capability. The MA2Z72000L operates at 500 mA. Substitute parts with equal or greater current ratings are electrically compatible.

Technology: All substitute parts utilize Schottky diode technology, maintaining identical switching characteristics and forward voltage behavior.

Package Compatibility: The original part uses SC-90 and SOD-323F packages. Substitute parts must use equivalent surface mount packages (SOD-323F or SOD-323) to ensure PCB footprint compatibility.

Reverse Recovery Time: Fast recovery characteristics (≤500 ns for currents >200 mA) are maintained across all substitute options.

Thermal Rating: Operating temperature specifications must support the application's thermal environment. The original part specifies 125°C maximum junction temperature.

Engineering Selection Recommendations

PMEG4005EJ,115 (Nexperia USA Inc.) provides the closest electrical match to the MA2Z72000L. This part maintains identical voltage and current ratings (40 V, 500 mA), operates at a lower forward voltage (470 mV vs. 550 mV at 500 mA), and uses the same SOD-323F package. The part is active in production, ROHS3 compliant, and carries AEC-Q100 automotive qualification. The maximum junction temperature of 150°C exceeds the original specification, providing additional thermal margin.

PMEG4002EJ,115 (Nexperia USA Inc.) is suitable for applications where the current requirement does not exceed 200 mA. This part shares the same voltage rating and package as the original, with superior reverse leakage characteristics (10 µA vs. 100 µA). It is active in production and ROHS3 compliant with AEC-Q100 qualification. Current derating is required for circuits designed for the full 500 mA capability of the MA2Z72000L.

SD103AWS-TP (Micro Commercial Co) operates at 350 mA average rectified current, positioning it between the 200 mA and 500 mA options. This part maintains the 40 V voltage rating and uses a compatible SOD-323 package. It is active in production and ROHS3 compliant. The reverse recovery time of 10 ns is longer than the original 5 ns specification. This part is suitable for applications with current requirements between 200 mA and 350 mA.

All three substitute parts are active in production, eliminating obsolescence concerns associated with the original MA2Z72000L.

Frequently Asked Questions (FAQ)

Q: Can PMEG4002EJ,115 replace MA2Z72000L in all applications?

A: PMEG4002EJ,115 is electrically compatible only for circuits where the average rectified current does not exceed 200 mA. The original MA2Z72000L is rated for 500 mA. If the circuit requires the full 500 mA capability, PMEG4005EJ,115 is the appropriate substitute.

Q: What is the difference between SOD-323F and SOD-323 packages?

A: Both packages are surface mount variants with identical footprints and pin configurations. SOD-323F and SOD-323 are mechanically and electrically interchangeable on PCBs designed for either package type. All substitute parts use one of these compatible package designations.

Q: Does the lower forward voltage of PMEG4005EJ,115 affect circuit operation?

A: The PMEG4005EJ,115 exhibits a forward voltage of 470 mV at 500 mA compared to 550 mV for the MA2Z72000L. This 80 mV reduction results in lower power dissipation and heat generation. Circuits designed for the original part will operate with improved efficiency. No circuit redesign is required.

Q: Are all substitute parts RoHS compliant?

A: Yes. PMEG4005EJ,115, PMEG4002EJ,115, and SD103AWS-TP are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Which substitute part has the best reverse leakage characteristics?

A: SD103AWS-TP exhibits the lowest reverse leakage current at 5 µA @ 30 V, followed by PMEG4002EJ,115 at 10 µA @ 40 V. The MA2Z72000L and PMEG4005EJ,115 both specify 100 µA @ 35 V and 40 V respectively. Lower reverse leakage reduces standby current consumption in the circuit.

Q: Can SD103AWS-TP be used as a direct replacement for MA2Z72000L?

A: SD103AWS-TP is suitable for applications where the average rectified current requirement is 350 mA or less. For circuits requiring the full 500 mA capability of the MA2Z72000L, PMEG4005EJ,115 is the appropriate choice. The reverse recovery time of SD103AWS-TP (10 ns) is longer than the original specification (5 ns), which may affect high-frequency switching performance.

Q: What is the inventory status of these substitute parts?

A: PMEG4002EJ,115 has 240,400 pieces in stock, PMEG4005EJ,115 has 12,050 pieces in stock, and SD103AWS-TP has 12,200 pieces in stock. All parts are available for immediate procurement.

Q: Do the substitute parts have automotive qualification?

A: PMEG4005EJ,115 and PMEG4002EJ,115 carry AEC-Q100 automotive qualification. SD103AWS-TP does not specify automotive qualification in the provided data.
