MBR130LSFT1H Equivalent & Substitute Parts

Part Overview

The MBR130LSFT1H 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-123F package. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and procurement needs. Active alternatives with identical or compatible electrical and mechanical specifications are available from onsemi and other manufacturers.

Substitute Part Grouping Explanation

Substitution of the MBR130LSFT1H is determined by equivalence in the following critical parameters: maximum reverse voltage (30 V), average rectified current rating (1 A minimum), forward voltage characteristics, fast recovery speed classification, and surface mount packaging compatibility. Substitute parts must maintain these electrical specifications to ensure functional interchangeability within the circuit design.

The MBR130LSFT1H has two identified substitutes:

Direct Equivalent (onsemi MBR130LSFT1G): Identical electrical specifications and package designation with active product status and improved moisture sensitivity rating.

Compatible Alternative (Vishay SL03-GS08): Meets or exceeds all critical electrical parameters with a different surface mount package footprint (DO-219AB versus SOD-123F).

Engineering Selection Recommendations

MBR130LSFT1G (onsemi): This part is the primary substitute for the obsolete MBR130LSFT1H. It maintains identical electrical specifications and package configuration while offering active product status and defined moisture sensitivity rating (MSL 1). This part is suitable for direct replacement in existing designs without circuit modification.

SL03-GS08 (Vishay): This part provides electrical compatibility with higher current capacity (1.1 A versus 1 A) and lower reverse leakage current (130 µA versus 1 mA). The package footprint differs (DO-219AB versus SOD-123F), requiring PCB layout verification. This part is suitable for applications where the enhanced current rating and leakage characteristics provide design margin. Both substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can MBR130LSFT1G be used as a direct replacement for MBR130LSFT1H?

A: Yes. The MBR130LSFT1G provides identical electrical specifications (30 V, 1 A, 380 mV forward voltage) and package designation (SOD-123F). No circuit design changes are required.

Q: What are the key differences between MBR130LSFT1G and SL03-GS08?

A: The primary differences are package footprint (SOD-123F versus DO-219AB), current rating (1 A versus 1.1 A), forward voltage (380 mV versus 430 mV at rated current), and reverse leakage current (1 mA versus 130 µA). Both meet the 30 V reverse voltage requirement and fast recovery speed specification.

Q: Does the SL03-GS08 package change require PCB redesign?

A: Yes. The SL03-GS08 uses a DO-219AB (SMF) package while the original part uses SOD-123F. PCB land pattern and layout must be verified for compatibility before implementation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both MBR130LSFT1G and SL03-GS08 are ROHS3 compliant and REACH unaffected, matching the compliance status of the original MBR130LSFT1H.

Q: What is the moisture sensitivity rating difference between the original and substitutes?

A: The MBR130LSFT1H has vendor-undefined MSL. Both substitutes are rated MSL 1 (Unlimited), indicating superior moisture handling characteristics and reduced risk during storage and assembly.

Q: Can SL03-GS08 be used in applications requiring exactly 1 A current?

A: Yes. The SL03-GS08 is rated for 1.1 A average rectified current, which exceeds the 1 A requirement. The part operates within specification at 1 A.
