Product Description

Vishay LS4148-GS08 is a silicon junction switching diode designed for fast switching applications. This diode features a superectifier structure with a glass passivated junction that ensures high reliability and excellent performance in demanding electrical environments.

The device supports a maximum forward current of 300 mA with a peak reverse voltage of 100 V. It offers fast switching with a peak reverse recovery time of just 4 ns and a low leakage current typically below 0.2 μA.

Designed in a surface mount 2-pin Quadro Melf package, measuring 3.5 mm in length, 1.7 mm width, and 1.5 mm height, it is constructed with a DO-204AL molded epoxy over a glass body. The matte tin plated leads are solderable per J-STD-002 and JESD 22-B102 standards, ensuring ease of assembly and reliability.

This diode withstands a high forward surge current of up to 2 A peak and operates across a wide temperature range from -65°C to 175°C, making it suitable for industrial, electronic manufacturing, instrumentation, and power supply applications.

Typical use cases include high voltage rectification in CRT and TV G2 grids, and as a snubber circuit diode in camera flashes, where fast recovery time and low leakage are critical for efficiency and performance.

Superectifier structure for high reliability condition. Cavity-free glass passivated junction for durability. Fast switching time ensures high efficiency. Low leakage current less than 0.2 microamps. High forward surge capability up to 2 A.

Surface mount Quadro Melf package with epoxy molding. Matte tin plated solderable leads compliant with JESD standards. Wide operating temperature from -65°C to 175°C. Color band indicates cathode end polarity. RoHS-compliant commercial grade component.
