MBR130T1 Equivalent & Substitute Parts

Part Overview

The MBR130T1 is a Schottky rectifier diode rated for 30 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-123 package. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement continuity. The MBR130T1 is RoHS non-compliant, which may restrict its use in applications subject to RoHS regulations. Active alternatives with equivalent or superior electrical characteristics are available from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR130T1 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Must be ≥ 30 V
• Current - Average Rectified (Io): Must be ≥ 1 A
• Technology: Schottky rectifier diode
• Mounting Type: Surface Mount
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Factors:

• Package / Case: SOD-123 or equivalent surface mount packages
• Voltage - Forward (Vf): Lower values preferred for efficiency
• Current - Reverse Leakage @ Vr: Lower values preferred for performance
• RoHS Compliance: Active substitutes should be ROHS3 compliant

Substitute parts are grouped into two categories: Direct Equivalents (identical electrical ratings and package) and Similar Alternatives (equivalent or superior electrical ratings with different package form factors).

Parameter Comparison

Engineering Selection Recommendations

MBR130T1G (onsemi) is the primary direct equivalent. This part maintains identical electrical specifications (30 V, 1 A) and SOD-123 package form factor. MBR130T1G is active in production status and ROHS3 compliant, addressing the obsolescence and regulatory compliance limitations of the original MBR130T1. Forward voltage is improved at 450 mV versus 470 mV. This substitute provides the highest compatibility for direct board-level replacement without design modification.

PMEG3010EH,115 (Nexperia USA Inc.) is a qualified alternative with identical voltage and current ratings in SOD-123F package. This part carries AEC-Q100 automotive qualification and is ROHS3 compliant. The SOD-123F package is mechanically compatible with SOD-123 footprints in most applications. Forward voltage is 560 mV, which is higher than the original specification. This substitute is suitable for applications requiring automotive-grade components.

SL03-GS18 (Vishay General Semiconductor) offers superior current rating (1.1 A) and improved forward voltage (430 mV @ 1.1 A) while maintaining 30 V reverse voltage specification. The DO-219AB package is a surface mount alternative to SOD-123. This substitute provides performance enhancement with lower forward voltage drop. ROHS3 compliance and active production status are confirmed.

BAT165E6327HTSA1 (Infineon Technologies) provides elevated reverse voltage (40 V) but reduced current rating (750 mA). This part is suitable only for applications where the 1 A current requirement can be reduced or where higher reverse voltage margin is required. The SOD-323 package is smaller than SOD-123, requiring PCB layout modification. ROHS3 compliance is confirmed.

Frequently Asked Questions (FAQ)

Q: Can MBR130T1G be used as a direct replacement for MBR130T1?

A: Yes. MBR130T1G is a direct equivalent with identical electrical specifications (30 V, 1 A) and SOD-123 package. No circuit modification is required. MBR130T1G is active in production and ROHS3 compliant, eliminating the obsolescence and regulatory compliance issues of MBR130T1.

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

A: SOD-123F is a variant of the SOD-123 package with enhanced mechanical robustness. Both packages are mechanically compatible with standard SOD-123 PCB footprints. PMEG3010EH,115 uses SOD-123F and is functionally interchangeable with SOD-123 designs.

Q: Can BAT165E6327HTSA1 replace MBR130T1 in all applications?

A: No. BAT165E6327HTSA1 has a reduced current rating of 750 mA compared to the 1 A specification of MBR130T1. This substitute is suitable only for applications where the circuit current does not exceed 750 mA. The SOD-323 package also requires PCB layout modification.

Q: Why does PMEG3010EH,115 have higher forward voltage than MBR130T1?

A: Forward voltage variation is a normal characteristic of Schottky diodes across different manufacturers and process technologies. PMEG3010EH,115 specifies 560 mV @ 1 A versus 470 mV @ 1 A for MBR130T1. This 90 mV difference may impact power dissipation in high-current applications. SL03-GS18 offers lower forward voltage at 430 mV @ 1.1 A.

Q: Is RoHS compliance required for my application?

A: RoHS compliance is mandatory for products sold in the European Union and many other jurisdictions. All substitute parts listed (MBR130T1G, BAT165E6327HTSA1, PMEG3010EH,115, SL03-GS18) are ROHS3 compliant. The original MBR130T1 is RoHS non-compliant and may not be acceptable for new designs or regulated applications.

Q: What is the advantage of SL03-GS18 over MBR130T1G?

A: SL03-GS18 offers improved forward voltage performance (430 mV @ 1.1 A) and higher current rating (1.1 A) compared to MBR130T1G (450 mV @ 700 mA). This results in lower power dissipation and greater current margin. The DO-219AB package is a surface mount alternative that may require PCB layout adjustment.

Q: Can I use multiple lower-current diodes in parallel to replace MBR130T1?

A: Parallel connection of Schottky diodes is not recommended due to unequal current distribution caused by forward voltage variations between devices. Direct substitution with equivalent or superior single-device ratings is the preferred engineering approach.

Q: What is the reverse recovery time specification for these diodes?

A: All listed substitutes maintain fast recovery characteristics (≤ 500ns, > 200mA). SL03-GS18 specifies reverse recovery time (trr) at 10 ns, which is superior performance. This parameter is critical for high-frequency switching applications.
