MBR120VLSFT1

MBR120VLSFT1 Description

The MBR120VLSFT1 from onsemi is a Schottky diode designed for high-efficiency rectification in fast-switching applications. With a 20V DC reverse voltage (Vr) and 1A average rectified current (Io), it features a low forward voltage drop (340mV @ 1A) and ultra-fast recovery time (<500ns), making it ideal for power-sensitive circuits. Packaged in a SOD123FL surface-mount format with Tape & Reel (TR) delivery, it complies with REACH Unaffected and EAR99 regulations, ensuring environmental and export compliance.

MBR120VLSFT1 Features

• Low Vf & Fast Recovery: Minimizes power loss and improves efficiency in high-frequency applications.
• High Current Handling: Supports 1A continuous current with 600µA max reverse leakage (@20V), reducing wasted energy.
• Robust Packaging: SOD123FL offers compact footprint and thermal performance for dense PCB layouts.
• Reliability: MSL 1 (Unlimited) moisture sensitivity ensures long shelf life and easy handling.
• Obsolete Status: While discontinued, it remains a proven choice for legacy designs requiring stable performance.

MBR120VLSFT1 Applications

• Power Supplies: DC-DC converters, SMPS, and voltage clamping circuits benefit from its low Vf and fast switching.
• Reverse Polarity Protection: Ideal for battery-powered devices due to minimal leakage and high surge tolerance.
• High-Frequency Circuits: RF detectors, mixers, and switching regulators leverage its <500ns recovery.
• Automotive & Industrial: Suitable for non-critical systems where Schottky efficiency outweighs obsolescence risks.

Conclusion of MBR120VLSFT1

The MBR120VLSFT1 excels in high-efficiency, fast-recovery applications, offering a balance of low forward drop, compact size, and reliable performance. While obsolete, its Schottky technology and surface-mount design make it a viable option for legacy or cost-sensitive projects requiring proven diode characteristics. Engineers should evaluate alternative active models for new designs but can rely on this diode for repairs or low-volume production.
