Product Description
Vishay LS4154GS08 is a 35 V, 300 mA fast switching diode designed for small signal applications in surface mount Quadro Melf package. This diode features a glass passivated junction that ensures high reliability and low leakage current, making it well suited for demanding industrial and electronic environments.
The diode exhibits a maximum continuous forward current of 300 mA, peak non-repetitive forward surge current of 2 A, and a very fast peak reverse recovery time of 4 nanoseconds. These characteristics enable efficient switching performance in circuits such as high voltage rectification of G2 grid CRTs, TV sets, and camera flash snubber circuits.
Encapsulated in a DO-204AL molded epoxy over glass body, the diode package measures 3.5 mm in length, 1.7 mm in width, and 1.5 mm in height. Matte tin plated leads ensure reliable solderability according to J-STD-002 and JESD 22-B102 standards. The device operates reliably from -65°C up to 175°C, allowing usage in harsh operating conditions.
The polarity is clearly marked with a color band indicating the cathode end, aiding in correct circuit assembly and replacement. The diode is commercial grade and RoHS-compliant, with no automotive certification. This product is designed to offer a combination of fast switching speed, high reliability, and ease of mounting for industrial, laboratory, telecommunications, and consumer electronics applications.
Features a glass passivated junction for enhanced durability and performance. Quadro Melf package minimizes PCB footprint and aids automated assembly. Fast switching reduces switching losses and improves efficiency. Low leakage current optimizes circuit performance and power consumption.
High surge current capability accommodates transient conditions safely. Wide operating temperature range supports diverse application environments. Matte tin plated leads and flammability-rated molding ensure robustness and safety.
Polarity marking facilitates correct installation and maintenance. Ideal for high voltage rectification and snubber circuit applications.
This Vishay fast switching diode LS4154GS08 is a reliable and efficient solution for high-speed switching and rectification requirements in industrial automation, electronic manufacturing, HVAC controls, and consumer electronics repair or design projects.
