MMDL301T1 Schottky Diode Equivalent & Substitute Parts

Part Overview

The MMDL301T1 is an RF Schottky diode manufactured by onsemi, rated for 30V peak reverse voltage with 200mW power dissipation in SOD-323 surface mount packaging. This part is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The MMDL301T1G represents the active production equivalent from the same manufacturer, while additional alternatives from Nexperia and Micro Commercial Co provide functional substitution options with varying current ratings and performance characteristics.

Substitute Part Grouping Explanation

Substitution for the MMDL301T1 is determined by the following critical parameters: peak reverse voltage (30V maximum), package type (SOD-323), diode technology (Schottky), and operating temperature range. The primary substitute MMDL301T1G maintains identical electrical specifications while offering active product status and RoHS3 compliance. Secondary substitutes from Nexperia (1PS76SB10,115 and 1PS76SB10,135) and Micro Commercial Co (B0530WS-TP) share the 30V voltage rating and SOD-323 package but differ in current handling capacity and forward voltage characteristics. The PMEG3010BEA,115 and PMEG3005AEA,115 options provide higher current ratings (1A and 500mA respectively) while maintaining the 30V voltage specification and SOD-323 package footprint.

Engineering Selection Recommendations

MMDL301T1G is the direct replacement for MMDL301T1, offering identical electrical performance with active product status and RoHS3 compliance. This part is recommended for designs requiring exact specification matching and regulatory compliance.

For applications where higher current capacity is acceptable, the 1PS76SB10 series (200mA rating) from Nexperia provides AEC-Q101 automotive qualification with active status and RoHS3 compliance. The 1PS76SB10,115 and 1PS76SB10,135 variants are functionally equivalent, differing only in packaging configuration.

The B0530WS-TP from Micro Commercial Co and PMEG3005AEA,115 from Nexperia both support 500mA operation at 30V in SOD-323 packaging with active product status and RoHS3 compliance. The PMEG3005AEA,115 includes AEC-Q100 automotive qualification and extends the maximum junction temperature to 150°C.

The PMEG3010BEA,115 supports 1A operation at 30V with AEC-Q100 automotive qualification, RoHS3 compliance, and 150°C maximum junction temperature, suitable for applications requiring higher current handling within the same package footprint.

All substitute parts maintain the SOD-323 package specification, ensuring mechanical and thermal compatibility with the original design. Selection should be based on application current requirements, temperature operating range, and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can MMDL301T1G be used as a direct replacement for MMDL301T1?

A: Yes. MMDL301T1G maintains identical electrical specifications including 30V peak reverse voltage, 200mW power dissipation, and SOD-323 packaging. The primary difference is product status (active vs. obsolete) and RoHS3 compliance.

Q: What is the difference between 1PS76SB10,115 and 1PS76SB10,135?

A: Both parts are functionally identical Schottky diodes rated for 30V and 200mA. The suffix designates packaging configuration (Cut Tape & Digi-Reel vs. alternative reel format). Electrical performance is equivalent.

Q: Can higher current-rated parts like PMEG3010BEA,115 (1A) replace the 200mW MMDL301T1?

A: Yes, from an electrical compatibility standpoint. Higher current-rated Schottky diodes maintain the 30V voltage specification and SOD-323 package. However, verify that the application circuit can accommodate the different forward voltage characteristics and thermal behavior of the substitute part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance status. The original MMDL301T1 is RoHS non-compliant, making RoHS3-compliant substitutes necessary for new designs subject to regulatory requirements.

Q: Do the Nexperia parts include automotive qualification?

A: The 1PS76SB10 series carries AEC-Q101 qualification. The PMEG3005AEA,115 and PMEG3010BEA,115 carry AEC-Q100 qualification. The B0530WS-TP from Micro Commercial Co does not list automotive qualification.

Q: What is the maximum operating temperature difference between substitutes?

A: The original MMDL301T1 and its direct replacement MMDL301T1G are rated to 150°C junction temperature. The 1PS76SB10 series and B0530WS-TP are limited to 125°C. The PMEG series extends to 150°C, matching the original specification.
