The document introduces the features and characteristics of Silicon Avalanche Diodes 294 and 1.5KE series products, which are designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. These devices are ideal for the protection of I/O interfaces, Vcc bus, and other vulnerable circuits used in telecom, computer, industrial, and consumer electronic applications.
The 1.5KE Series is designed to protect sensitive electronic equipment from voltage transients caused by lightning, switching, and other surge events. It is suitable for VO interfaces, Vcc buses, and other vulnerable circuits in telecom, computer, industrial, and consumer applications.
Key features include RoHS compliance, a voltage rating from 6.8 V to 550 V, both uni‑directional and bi‑directional options, a 1500 W surge capability, low zener impedance, and a compact DO‑201 axial leaded package. Mechanical data list a weight of 0.045 oz (1.2 g) and a molded plastic case.
