MBRA130LT3 Equivalent & Substitute Parts

Part Overview

The MBRA130LT3 is a Schottky rectifier diode rated for 30 V DC reverse voltage and 1 A average rectified current in a surface mount SMA package (DO-214AC). This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The part exhibits fast recovery characteristics with switching speed ≤ 500 ns at currents > 200 mA, suitable for high-frequency rectification and power conversion applications.

Substitute Part Grouping Explanation

Substitution of the MBRA130LT3 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

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

Package Considerations: Substitute parts are grouped into two categories based on package type:

DO-214AC / SMA Package Group — Direct mechanical and electrical equivalents with identical footprint and lead configuration
Alternative Surface Mount Packages — Parts meeting all electrical specifications but with different package geometries (SOD-323, SOD-128), requiring PCB layout modification

All substitute parts listed maintain the 30 V reverse voltage rating and 1 A current rating. Forward voltage drop and reverse leakage current may vary within acceptable engineering tolerances for Schottky diode technology. Operating temperature range and RoHS compliance status are provided for design and procurement considerations.

Engineering Selection Recommendations

Primary Recommendation — Direct Replacement:

MBRA130LT3G (onsemi) is the direct successor to the obsolete MBRA130LT3. This part maintains identical electrical specifications (30 V, 1 A, 410 mV forward voltage) and package configuration (DO-214AC, SMA). The MBRA130LT3G is active in production, ROHS3 compliant, and available in standard packaging formats (Cut Tape and Digi-Reel). This part requires no design modification and is the preferred choice for direct substitution.

Secondary Recommendations — Same Package, Active Status:

SS13-E3/61T (Vishay) and B130-13-F (Diodes Incorporated) are functionally equivalent alternatives in the DO-214AC/SMA package. Both parts are active, ROHS3 compliant, and maintain the 30 V / 1 A electrical rating. Forward voltage specifications differ slightly (500 mV vs. 410 mV), which is within normal Schottky diode tolerance ranges. These parts are suitable for applications where forward voltage drop variation is acceptable.

Alternative Package Options:

BAS3010A03WE6327HTSA1 (Infineon, SOD-323 package) and PMEG3010EP,115 (Nexperia, SOD-128 package) meet all electrical requirements but require PCB layout modification due to different package footprints. These options are appropriate when space constraints or design requirements necessitate smaller package formats. Both are ROHS3 compliant and active in production.

Compliance Considerations:

The original MBRA130LT3 is RoHS non-compliant. All recommended substitutes are ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Frequently Asked Questions (FAQ)

Q: Can MBRA130LT3G be used as a direct replacement for MBRA130LT3?

A: Yes. MBRA130LT3G is the active production equivalent of the obsolete MBRA130LT3. Both parts share identical electrical specifications (30 V reverse voltage, 1 A current rating, 410 mV forward voltage at 1 A) and the same DO-214AC/SMA package. No design changes are required.

Q: What is the difference between the DO-214AC/SMA package and SOD-323 or SOD-128 packages?

A: DO-214AC (SMA) is a larger surface mount package with different lead spacing and footprint compared to SOD-323 and SOD-128. Parts using alternative packages require PCB layout modification and cannot be used as direct drop-in replacements without redesign.

Q: Why do some substitute parts have different forward voltage specifications?

A: Forward voltage drop in Schottky diodes varies with manufacturing process and semiconductor material composition. The MBRA130LT3 specifies 410 mV at 1 A, while alternatives range from 360 mV to 500 mV. These variations are within normal Schottky diode operating parameters and do not affect functional compatibility in most applications. Circuit designers should verify forward voltage drop impact on specific application requirements.

Q: Are all substitute parts ROHS compliant?

A: All recommended substitute parts are ROHS3 compliant. The original MBRA130LT3 is RoHS non-compliant. Substitution with ROHS3 compliant parts aligns with current regulatory requirements.

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

A: Reverse leakage current (Ir) varies among Schottky diode manufacturers and process technologies. The MBRA130LT3 specifies 1 mA at 30 V, while substitutes range from 200 µA to 1.5 mA. These variations are typical for Schottky technology and do not indicate functional incompatibility. Applications sensitive to leakage current should verify specifications against circuit requirements.

Q: Can I use SS13 (Fairchild Semiconductor) as a substitute?

A: SS13 meets the electrical requirements (30 V, 1 A, fast recovery) and uses the DO-214AC/SMA package. However, it is available only in bulk packaging, which may not align with standard procurement practices. SS13-E3/61T (Vishay equivalent) is the preferred alternative, offering the same electrical specifications with standard tape and reel packaging.

Q: What packaging formats are available for substitute parts?

A: MBRA130LT3G, SS13-E3/61T, and B130-13-F are available in Cut Tape (CT) and Digi-Reel formats. BAS3010A03WE6327HTSA1 and PMEG3010EP,115 are available in Cut Tape and Digi-Reel. SS13 is available in bulk packaging only.
