MST518-LF** is a **surface-mount Schottky barrier diode** designed for high-efficiency rectification applications.

The MST518-LF is a surface-mount Schottky barrier diode designed for high-efficiency rectification applications. Below are its key specifications, descriptions, and features:

Specifications:

  • Manufacturer: Micro Commercial Components (MCC)
  • Type: Schottky Diode
  • Package: SOD-123FL (Surface Mount)
  • Maximum Reverse Voltage (VR): 20V
  • Average Forward Current (IF): 500mA
  • Peak Forward Surge Current (IFSM): 2A
  • Forward Voltage Drop (VF): 0.38V (at 500mA)
  • Reverse Leakage Current (IR): 100µA (at 20V)
  • Junction Temperature (TJ): -55°C to +125°C
  • Storage Temperature (TSTG): -55°C to +150°C

Descriptions:

  • The MST518-LF is a low-power Schottky diode optimized for high-speed switching, low forward voltage drop, and minimal leakage current.
  • It is commonly used in power management, DC-DC converters, reverse polarity protection, and signal clamping applications.
  • The SOD-123FL package provides a compact footprint suitable for space-constrained PCB designs.

Features:

  • Low forward voltage drop (0.38V @ 500mA) for improved efficiency.
  • Fast switching speed for high-frequency applications.
  • Low reverse leakage current enhances power-saving performance.
  • Lead-free and RoHS compliant for environmental safety.
  • High surge current capability (2A) for transient protection.

This diode is ideal for portable electronics, power supplies, and battery-operated devices where energy efficiency and compact size are critical.
