MBR130T3 Equivalent & Substitute Parts

Part Overview

The MBR130T3 is a Schottky rectifier diode manufactured by onsemi, rated for 30 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-123 package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The MBR130T3 is suitable for applications requiring fast recovery rectification with low forward voltage drop characteristics typical of Schottky technology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBR130T3 are selected based on electrical and mechanical compatibility within the following criteria:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Technology: Schottky
• Mounting Type: Surface Mount
• Operating Temperature Range: Must accommodate -65°C to 125°C junction temperature or higher

Package Compatibility: Substitutes are grouped into two categories: direct package equivalents (SOD-123) and compatible alternative packages (SOD-123F, DO-219AB) that maintain electrical performance within the same form factor class.

Compliance Considerations: The MBR130T3 is RoHS non-compliant. Active substitute parts listed are ROHS3 compliant, providing compliance upgrade paths for new designs.

Parameter Comparison

Engineering Selection Recommendations

MBR130T3G (onsemi)

The MBR130T3G is the direct successor to the MBR130T3, manufactured by the same supplier. It maintains identical electrical ratings and package form factor while providing ROHS3 compliance. This part is recommended as the primary replacement for obsolete MBR130T3 applications requiring continuity with the original design. The MBR130T3G exhibits improved forward voltage characteristics at reduced current levels (450 mV @ 700 mA versus 470 mV @ 1 A).

B130LAW-7-F (Diodes Incorporated)

The B130LAW-7-F provides equivalent electrical performance with the lowest forward voltage drop (420 mV @ 1 A) among all substitutes. This part is suitable for applications where power dissipation optimization is required. The operating temperature range extends to -55°C minimum, which is acceptable for most industrial applications. Reverse leakage current is elevated at 1 mA @ 30 V compared to the original specification.

PMEG3010EH,115 (Nexperia USA Inc.)

The PMEG3010EH,115 is qualified to AEC-Q100 automotive standards and features the highest maximum junction temperature rating (150°C). This part is specified in an SOD-123F package variant and is suitable for automotive and high-temperature applications. Forward voltage is elevated at 560 mV @ 1 A, resulting in higher power dissipation than the original design.

SL03-GS18 (Vishay General Semiconductor)

The SL03-GS18 is rated for 1.1 A average rectified current, providing 10% current margin above the original specification. This part uses the DO-219AB (SMF) package, which is mechanically compatible with SOD-123 footprints in most PCB designs. The reverse recovery time specification (10 ns) is explicitly provided. This part is suitable for applications requiring enhanced current capacity within the same voltage class.

Frequently Asked Questions (FAQ)

Q: Can the MBR130T3G be used as a direct replacement for the MBR130T3?

A: Yes. The MBR130T3G is electrically and mechanically equivalent to the MBR130T3, with identical voltage and current ratings, package form factor, and operating temperature range. The primary difference is active product status and ROHS3 compliance.

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

A: SOD-123F is a variant of the SOD-123 package with modified lead geometry. Both packages are surface mount and occupy similar PCB footprints. The PMEG3010EH,115 uses SOD-123F packaging and is compatible with standard SOD-123 land patterns in most applications.

Q: Which substitute has the lowest forward voltage drop?

A: The B130LAW-7-F exhibits the lowest forward voltage drop at 420 mV @ 1 A, compared to 470 mV @ 1 A for the original MBR130T3. This results in reduced power dissipation and heat generation in the application circuit.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original MBR130T3 is RoHS non-compliant. Selection of any substitute part provides automatic compliance upgrade for new designs.

Q: What is the difference between the DO-219AB and SOD-123 packages?

A: DO-219AB (SMF) is a surface mount package with different lead configuration than SOD-123. Both are surface mount packages suitable for automated assembly. PCB footprint compatibility must be verified during design integration, though many modern designs accommodate both package types on the same land pattern.

Q: Which substitute part has the highest current rating?

A: The SL03-GS18 is rated for 1.1 A average rectified current, providing 10% additional current capacity compared to the 1 A rating of the MBR130T3 and other substitutes.

Q: Can the PMEG3010EH,115 be used in high-temperature applications?

A: Yes. The PMEG3010EH,115 is rated for a maximum junction temperature of 150°C, which is 25°C higher than the original MBR130T3 specification. This part is qualified to AEC-Q100 automotive standards and is suitable for elevated temperature environments.

Q: What is the reverse leakage current specification for each substitute?

A: Reverse leakage current at 30 V varies among substitutes: MBR130T3G (60 µA), B130LAW-7-F (1 mA), PMEG3010EH,115 (150 µA), and SL03-GS18 (130 µA). The MBR130T3G maintains the original specification of 60 µA.
