Vishay Silicon Junction Switching Diode, Single, 300 mA, 100 V, Surface Mount, Quadro Melf Package LS4148-GS08

Vishay LS4148-GS08 Silicon Junction Switching Diode offers a compact and efficient solution for switching applications in electronic and electrical devices. This single diode features a maximum forward current of 300 mA and supports a peak reverse repetitive voltage of 100 V, delivered in a surface mount Quadro Melf package.

The diode is designed with a superectifier structure and glass-passivated junction, ensuring high reliability and minimal leakage current typically below 0.2 μA. Fast switching capability with a peak reverse recovery time of just 4 ns enables it to perform well in circuits operating at high frequencies.

Mechanically, the diode comes in a molded epoxy DO-204AL case with matte tin plated leads that conform to J-STD-002 solderability standards, guaranteeing ease of assembly. The device withstands extreme temperatures, operating up to 175°C and sustaining non-operating temperatures from -65°C, making it ideal for industrial, automotive, and consumer electronics applications.

Applications include high voltage rectification such as G2 grid CRT and TV circuits, as well as snubber circuits in photographic camera flashes. The diode's compact size and robust performance make it well suited for dense PCB layouts and reliable switching functions.

The diode has a maximum forward current of 300 mA providing reliable operation. It features a low forward voltage drop of 1 V for efficient conduction. The device supports a peak reverse repetitive voltage of 100 V ensuring good blocking capability.

Fast switching speed with a peak reverse recovery time of 4 ns enhances high-frequency performance. The diode is glass-passivated and uses a superectifier structure for high reliability. With a maximum operating temperature of 175°C and storage down to -65°C, it is suitable for demanding environments.

Package dimensions are compact: length 3.5 mm, width 1.7 mm, height 1.5 mm, and diameter 1.6 mm. Terminals are matte tin plated leads solderable according to J-STD-002 and JESD 22-B102 standards. Color band on the diode denotes the cathode end for easy polarity identification.

Typical applications include high voltage rectification for CRT and TV, and snubber circuits in camera flash units.
