MA2SD3000L Equivalent & Substitute Parts

Part Overview

The MA2SD3000L is a Schottky diode manufactured by Panasonic Electronic Components, rated for 30 V DC reverse voltage and 100 mA average rectified current in a surface mount SSMini2-F1 package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The MA2SD3000L operates with a maximum forward voltage of 580 mV at 100 mA and exhibits a reverse recovery time of 1 ns. Its small signal speed classification and low reverse leakage current of 2 µA at 30 V make it suitable for high-frequency switching applications requiring minimal power dissipation.

Current - Average Rectified (Io): 100 mA minimum
Technology: Schottky diode
Package / Case: SC-79, SOD-523 (surface mount)
Mounting Type: Surface Mount

Secondary Compatibility Factors:

Speed Classification: Small Signal ≤ 200mA (Io), Any Speed
Reverse Recovery Time (trr): ≤ 5 ns

Engineering Selection Recommendations

Direct Equivalents (100 mA Current Rating):

RB500SM-30FHT2R and RB501SM-30FHT2R from Rohm Semiconductor are the closest functional equivalents to the MA2SD3000L. Both maintain the 30 V / 100 mA rating and small signal speed classification. RB501SM-30FHT2R offers superior forward voltage performance (350 mV @ 10 mA) compared to RB500SM-30FHT2R (450 mV @ 10 mA). Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance, with active product status ensuring long-term availability.

Higher Current Capability Substitutes:

RB520S30T1G and SBAT54XV2T1G from onsemi provide 200 mA current ratings, offering 2× the current capacity of the original part. These substitutes are suitable for applications requiring additional current margin or thermal headroom. RB520S30T1G exhibits superior reverse leakage characteristics (1 µA @ 10 V) and extended operating temperature range (-55°C to 150°C). SBAT54XV2T1G maintains the 1 ns reverse recovery time specification of the original part.

Higher Current Density Substitute:

PMEG3010EB,115 from Nexperia USA Inc. provides 1 A current rating in the same SOD-523 package. This part is suitable for applications requiring significant current margin or where thermal performance is critical. It carries AEC-Q100 automotive qualification and ROHS3 compliance. Higher reverse leakage (500 µA @ 30 V) and forward voltage (680 mV @ 1 A) must be evaluated against application requirements.

Lower Current Substitute:

RB751S40T5G from onsemi is rated for 30 mA and is suitable only for applications with reduced current requirements. This part exhibits the lowest forward voltage (370 mV @ 1 mA) and minimal reverse leakage (500 nA @ 30 V), making it appropriate for low-power, high-efficiency circuits.

All substitute parts maintain SC-79 / SOD-523 package compatibility, surface mount configuration, and MSL 1 moisture sensitivity rating. Selection should be based on specific application current requirements, thermal constraints, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can RB501SM-30FHT2R directly replace MA2SD3000L in all applications?

A: RB501SM-30FHT2R is a direct functional equivalent, matching the 30 V / 100 mA rating and small signal speed classification. Both parts use SC-79 / SOD-523 surface mount packages. The primary difference is improved forward voltage performance (350 mV @ 10 mA vs. 580 mV @ 100 mA), which reduces power dissipation. Verification of circuit performance is required for applications sensitive to forward voltage characteristics.

Q: What is the difference between RB500SM-30FHT2R and RB501SM-30FHT2R?

A: Both parts are 30 V / 100 mA Schottky diodes in EMD2 packages. RB501SM-30FHT2R provides lower forward voltage (350 mV @ 10 mA) and lower reverse leakage (10 µA @ 10 V) compared to RB500SM-30FHT2R (450 mV @ 10 mA and 500 nA @ 10 V respectively). RB501SM-30FHT2R is preferred for applications prioritizing reduced power dissipation.

Q: When should PMEG3010EB,115 be selected over RB501SM-30FHT2R?

A: PMEG3010EB,115 is rated for 1 A current, providing 10× the current capacity of the original MA2SD3000L. Selection is appropriate for applications requiring higher current handling, thermal margin, or where future design scaling is anticipated. The higher reverse leakage (500 µA @ 30 V) and forward voltage (680 mV @ 1 A) must be acceptable within circuit design constraints.

Q: Are all substitute parts automotive qualified?

A: RB500SM-30FHT2R, RB501SM-30FHT2R, and PMEG3010EB,115 carry automotive qualifications (AEC-Q101 or AEC-Q100). RB520S30T1G, RB751S40T5G, and SBAT54XV2T1G do not list automotive qualifications in the provided specifications. Automotive applications must verify qualification status with manufacturer documentation.

Q: Can RB751S40T5G be used as a substitute for MA2SD3000L?

A: RB751S40T5G is rated for only 30 mA average rectified current, which is below the 100 mA requirement of the original part. This substitute is suitable only for applications with reduced current requirements and cannot be used as a direct replacement in circuits designed for 100 mA operation.

Q: What is the impact of higher current ratings on circuit performance?

A: Substitute parts with higher current ratings (RB520S30T1G at 200 mA, PMEG3010EB,115 at 1 A) provide additional thermal margin and reduce power dissipation per unit current. These parts are electrically compatible with lower-current designs but may exhibit different parasitic characteristics. Circuit validation is required to confirm performance equivalence.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance certification. The original MA2SD3000L does not specify RoHS status. Designs requiring RoHS compliance should select from the active substitute parts, all of which meet ROHS3 requirements.

Q: What packaging options are available for substitutes?

A: All substitute parts maintain SC-79 / SOD-523 surface mount package compatibility with the original MA2SD3000L. Packaging formats vary between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) configurations. Procurement specifications should confirm packaging format compatibility with assembly equipment and processes.

Q: How do reverse recovery time specifications affect substitution?

A: The original MA2SD3000L specifies 1 ns reverse recovery time. SBAT54XV2T1G matches this specification at 5 ns. Other substitutes do not provide reverse recovery time data. Applications sensitive to switching transients or high-frequency operation should prioritize parts with specified reverse recovery time characteristics.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current ranges from 500 nA (RB500SM-30FHT2R, RB751S40T5G) to 500 µA (PMEG3010EB,115). Lower leakage reduces standby power consumption and improves circuit efficiency. Applications operating at elevated temperatures or requiring minimal standby current should select parts with lower reverse leakage specifications.
