STMICROELECTRONICS SM5908 Transient Voltage Suppressor Diode

The SM5908 is a unidirectional Transil™ Transient Voltage Suppressor diode designed for surge and electrostatic discharge protection of sensitive electronic equipment. It complies with IEC 61000-4-2 level 4, MIL STD 883, and IEC 61000-4-4/5 standards, making it suitable for applications below 1500W (10/1000µs). Crafted with planar technology, it offers low leakage current and high junction temperature stability, ideal for high-end devices and switch-mode power supplies. It features a typical capacitance of 9500pF, UL94V-0 flame-retardant resin, and an operating temperature range from -55°C to +175°C. Suitable for power management, industrial systems, communications, defense, and aerospace sectors, the component's lead times may vary due to high demand.
