Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR120ESFT1 are grouped based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters (Must Match or Exceed):

• Voltage - DC Reverse (Vr) (Max): 20V minimum
• Current - Average Rectified (Io): 1A minimum
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: SOD-123F or equivalent footprint compatibility

Compliance Parameters:

• RoHS Status: Active production parts with ROHS3 compliance preferred
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts are classified into three categories:

Direct Manufacturer Equivalent: MBR120ESFT1G maintains identical electrical specifications and is the direct active production replacement from onsemi.

Parametric Equivalent: MBR120ESFT3G differs only in packaging format (Tape & Reel vs. Cut Tape) while maintaining all electrical parameters.

Similar Alternatives: Parts from Nexperia and Toshiba that meet or exceed the core electrical requirements (20V, 1A Schottky, fast recovery) but may have variations in forward voltage, leakage current, or package dimensions.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MBR120ESFT1G

MBR120ESFT1G is the direct active production equivalent from onsemi. It maintains identical electrical specifications to the obsolete MBR120ESFT1 while achieving ROHS3 compliance. This part is recommended for designs requiring exact parameter matching and onsemi sourcing continuity. Packaging is available in Cut Tape (CT) & Digi-Reel® format with 20,300 pieces in stock.

Secondary Recommendation: MBR120ESFT3G

MBR120ESFT3G provides identical electrical performance to MBR120ESFT1G with packaging in Tape & Reel (TR) format. Selection between MBR120ESFT1G and MBR120ESFT3G depends on procurement and assembly requirements. Both are ROHS3 compliant active products.

Alternative Selections Based on Application Requirements:

For applications where forward voltage reduction is beneficial, PMEG2010ER,115 (340 mV @ 1A) or CRS06(TE85L,Q,M) (360 mV @ 1A) provide lower forward voltage drop. CRS06(TE85L,Q,M) offers significantly higher inventory availability (273,200 pieces) and is qualified to AEC-Q100 automotive standards.

For applications requiring higher current capacity, PMEG2015EH,115 (1.5A) or PMEG2020EH,115 (2A) maintain 20V rating with increased current handling. PMEG2020EH,115 includes AEC-Q100 automotive qualification.

For current-limited applications, PMEG2005EH,115 (500mA) provides reduced current rating with lower forward voltage (390 mV @ 500mA).

All recommended alternatives are ROHS3 compliant, MSL 1 (Unlimited), and maintain fast recovery Schottky technology specifications.

Frequently Asked Questions (FAQ)

Q: Can MBR120ESFT1G directly replace MBR120ESFT1 in existing designs?

A: Yes. MBR120ESFT1G is the direct active production equivalent with identical electrical specifications (20V, 1A, 530 mV forward voltage @ 1A, 10 µA leakage @ 20V). The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). Footprint and electrical performance are identical.

Q: What is the difference between MBR120ESFT1G and MBR120ESFT3G?

A: Both parts are electrically identical. The difference is packaging format: MBR120ESFT1G is supplied in Cut Tape (CT) & Digi-Reel® format, while MBR120ESFT3G is supplied in Tape & Reel (TR) format. Selection depends on assembly line requirements and procurement preferences.

Q: Can I use PMEG2010EH,115 instead of MBR120ESFT1?

A: PMEG2010EH,115 is electrically compatible with identical 20V and 1A ratings. However, forward voltage is 500 mV @ 1A compared to 530 mV for MBR120ESFT1, and reverse leakage is 200 µA @ 20V compared to 10 µA. These differences are within acceptable ranges for most applications but should be verified for designs with tight power dissipation or leakage current budgets. PMEG2010EH,115 includes AEC-Q100 automotive qualification.

Q: Why do some alternatives have different package designations (SOD-123W vs. SOD-123FL)?

A: SOD-123W and SOD-123FL are both surface mount packages in the SOD-123 family but have different physical dimensions. SOD-123W is wider than SOD-123FL. Verify PCB footprint compatibility before selecting parts with different package designations. Parts with matching SOD-123F designation are directly compatible.

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

A: CRS06(TE85L,Q,M) meets the core electrical requirements (20V, 1A, fast recovery Schottky) and offers superior forward voltage performance (360 mV @ 1A). However, reverse leakage is significantly higher (1 mA @ 20V vs. 10 µA). This part is suitable for applications where forward voltage efficiency is prioritized and leakage current is not a constraint. CRS06 is AEC-Q100 qualified and has high inventory availability.

Q: What does RoHS3 compliance mean for this application?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. All active production alternatives listed are ROHS3 compliant. The original MBR120ESFT1 is non-compliant, making active equivalents necessary for new designs subject to RoHS regulations.

Q: Can I use higher current rated parts like PMEG2020EH,115 (2A) as a drop-in replacement?

A: Yes. PMEG2020EH,115 maintains 20V rating with doubled current capacity (2A vs. 1A). This provides design margin and is electrically compatible. Forward voltage is 525 mV @ 2A, which is comparable to the original specification. Higher current rating does not create compatibility issues in circuits designed for 1A operation.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed parts share this rating, eliminating moisture sensitivity as a selection criterion.
