This document describes the features and characteristics of the Silicon Avalanche Diodes 294 w w w. l i t t e l f u s e . c o m 1500 Watt Axial Leaded Transient Voltage Suppressors. These devices are designed specifically to protect sensitive electronics equipment from voltage transients induced by lightning and other transient voltage events. They 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 silicon avalanche diodes are designed to protect sensitive electronic equipment from voltage transients such as lightning. They are suitable for I/O interfaces, Vcc buses and other vulnerable circuits in telecom, computer, industrial and consumer electronics.
Key features include 1500 W surge capability at a 10/1000 µs waveform, a voltage range of 6.8 V to 550 V, uni‑directional and bi‑directional options, and a glass‑passivated chip junction in a DO‑201 axial leaded package. The devices are RoHS compliant and offer low Zener impedance and typical reverse leakage below 1 µA above 10 V.
