14KESD5.0-14KESD170CA is a TVS diode from Microsemi. It is mainly used to protect sensitive circuits from ESD or EFT transients. The device has good clamping voltage performance, and can clamp 40000V ESD surges in 150ns rise time, and can clamp 4000W ESD surges in 1us rise time. The device adopts DO-41 package, low power consumption and easy to use.
The 14KESD series are axial‑lead transient voltage suppressor (TVS) devices that protect circuits from fast, high‑energy electrostatic discharge and electrical fast transients. They offer a wide stand‑off voltage range from 5 V to 170 V and can clamp pulses with peak powers up to 4000 W for a 1 µs square wave.
These components are supplied in a hermetically sealed DO‑41 axial‑lead glass package (also available in a surface‑mount DO‑213AB MELF package). Key electrical parameters, mechanical dimensions and thermal characteristics are listed in the tables, with operating temperatures from –65 °C to 175 °C.
