Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR120ESFT3G are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 20 V (exact match required)
• Current - Average Rectified (Io): 1 A (exact match or higher rating acceptable)
• Technology: Schottky (required)
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (required)
• Mounting Type: Surface Mount (required)
• Package / Case: SOD-123F or equivalent footprint (SOD-123FL, SOD-123W, S-FLAT, DO-219AB acceptable)
• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (required)

Secondary Considerations:

• Voltage - Forward (Vf) (Max) @ If: Variations within the Schottky diode characteristic range
• Current - Reverse Leakage @ Vr: Variations acceptable within fast recovery Schottky specifications
• Operating Temperature - Junction: Maximum rating of 125°C or higher acceptable

Substitute parts meeting these criteria are functionally interchangeable in applications designed for the MBR120ESFT3G specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (SOD-123F Package, 1 A Rating):

PMEG2010AEH,115, PMEG2010EH,115, and SM5817PL-TP are direct functional equivalents to the MBR120ESFT3G. All three maintain the 20 V reverse voltage rating, 1 A average rectified current, SOD-123F package footprint, and RoHS3 compliance. PMEG2010AEH,115 and PMEG2010EH,115 carry AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade reliability. SM5817PL-TP provides equivalent performance with extended inventory availability.

Alternative Package Options (1 A Rating):

PMEG2010BER,115 and PMEG2010ER,115 provide 1 A performance in SOD-123W package format. These are suitable when PCB layout accommodates the wider SOD-123W footprint. Both maintain 20 V reverse voltage rating and RoHS3 compliance.

Higher Current Ratings (20 V Reverse Voltage):

PMEG2015EH,115 (1.5 A) and PMEG2020EH,115 (2 A) are suitable for applications requiring higher current capacity while maintaining the 20 V reverse voltage specification. Both are RoHS3 compliant and AEC-Q100 qualified.

Lower Current Rating:

PMEG2005EH,115 is rated for 500 mA average rectified current. This part is suitable only for applications with reduced current requirements below 1 A.

Alternative Voltage/Current Combination:

CRS06(TE85L,Q,M) provides 20 V reverse voltage and 1 A rating in S-FLAT package. This Toshiba part is RoHS3 compliant and suitable for applications where the S-FLAT footprint is acceptable.

Alternative Package (1.1 A Rating):

SL02-GS08 is a Vishay eSMP® series Schottky diode rated for 1.1 A in DO-219AB (SMF) package. This part maintains 20 V reverse voltage and RoHS3 compliance, suitable for applications accommodating the DO-219AB footprint.

Frequently Asked Questions (FAQ)

Q: Can PMEG2005EH,115 replace MBR120ESFT3G?

A: PMEG2005EH,115 is rated for 500 mA average rectified current, while MBR120ESFT3G is rated for 1 A. PMEG2005EH,115 is not suitable as a direct replacement for applications requiring 1 A operation. It is only applicable for circuits designed for 500 mA or lower current.

Q: What is the difference between SOD-123F and SOD-123FL packages?

A: SOD-123F and SOD-123FL are equivalent footprints for surface mount Schottky diodes. Both are acceptable for the MBR120ESFT3G application. The "L" designation in SOD-123FL indicates lead-free termination, consistent with RoHS3 compliance.

Q: Are PMEG2010BER,115 and PMEG2010ER,115 compatible with MBR120ESFT3G?

A: PMEG2010BER,115 and PMEG2010ER,115 are functionally equivalent to MBR120ESFT3G in electrical performance (20 V, 1 A, Schottky, fast recovery). However, they use SOD-123W package instead of SOD-123F. Compatibility depends on PCB layout. If the PCB footprint is designed for SOD-123F, these parts require layout modification.

Q: Can I use PMEG2015EH,115 or PMEG2020EH,115 in place of MBR120ESFT3G?

A: Yes. PMEG2015EH,115 (1.5 A) and PMEG2020EH,115 (2 A) are electrically compatible with MBR120ESFT3G. Both maintain 20 V reverse voltage rating, Schottky technology, fast recovery speed, SOD-123F package, and RoHS3 compliance. Higher current ratings provide design margin for applications with variable or peak current conditions.

Q: What is the significance of AEC-Q100 qualification?

A: AEC-Q100 qualification indicates the part meets automotive industry reliability standards. PMEG2010AEH,115, PMEG2010EH,115, and PMEG2020EH,115 carry this qualification. For non-automotive applications, AEC-Q100 qualification is not required but provides additional assurance of component reliability.

Q: How do forward voltage differences affect substitution?

A: Forward voltage (Vf) variations among Schottky diodes are normal within the technology. MBR120ESFT3G specifies 530 mV maximum at 1 A. Substitute parts range from 340 mV to 660 mV depending on current rating and manufacturer. Lower Vf reduces power dissipation; higher Vf increases dissipation. Selection depends on thermal design requirements. All listed substitutes operate within acceptable Schottky diode characteristics.

Q: Is CRS06(TE85L,Q,M) a suitable replacement?

A: CRS06(TE85L,Q,M) is electrically equivalent (20 V, 1 A, Schottky, fast recovery, RoHS3). However, it uses S-FLAT (1.6x3.5) package instead of SOD-123F. Compatibility requires PCB footprint verification. The part is suitable only if the PCB layout accommodates S-FLAT dimensions.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates the diode has a reverse recovery time of 500 nanoseconds or less when switching from forward to reverse bias at currents exceeding 200 mA. This characteristic is essential for high-frequency switching applications. All listed substitute parts meet this requirement.

Q: Can SL02-GS08 replace MBR120ESFT3G?

A: SL02-GS08 is electrically compatible (20 V, 1.1 A, Schottky, fast recovery, RoHS3). However, it uses DO-219AB (SMF) package instead of SOD-123F. Compatibility requires PCB footprint verification. The part is suitable only if the PCB layout accommodates DO-219AB dimensions.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1 rating, meaning they can be stored and handled without special moisture control procedures prior to soldering.
