Vishay Silicon Junction Switching Diode, Single, 300 mA, 2-Pin, 100 V Quadro Melf LS4148-GS08

Vishay LS4148-GS08 is a high reliability silicon junction switching diode designed for electronic applications requiring fast switching and low leakage current. It features a single diode configuration in a compact Quadro Melf surface-mount package, making it suitable for automated assembly in electronics manufacturing.

This diode supports a maximum forward current of 300 mA and a peak reverse repetitive voltage of 100 V, ensuring suitability in circuits that require high voltage rectification and protection. It achieves a fast peak reverse recovery time of 4 ns to support high-frequency switching applications with minimal loss.

The device is constructed with a cavity-free glass-passivated junction for enhanced reliability and longevity. The case is molded epoxy over a glass body reviewed to UL 94 V-0 flammability standards, suitable for industrial and commercial electronic products.

Operating temperature ranges from -65°C to 175°C allow deployment in harsh environmental conditions such as industrial, laboratory, and commercial electronics. The diode also features a high forward surge capability up to 2 A to tolerate transient currents.

The matte tin plated leads are solderable according to J-STD-002 and JESD 22-B102 standards, facilitating robust PCB assembly processes. The cathode end is clearly indicated by a color band to avoid polarity errors during installation.

Typical applications include high voltage rectification in CRT and TV devices, snubber circuits for camera flashes, and general-purpose fast switching in power supplies and signal processing circuits.

The diode supports a maximum forward current of 300 mA. It has a peak reverse repetitive voltage of 100 V suitable for high voltage rectification. Fast switching with peak reverse recovery time of 4 nanoseconds ensures high efficiency.
