Description

The 3KP Series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by
lightning and other transient voltage events.

Features

•

VBR @TJ= VBR@25°C × (1+αT

x (TJ - 25))

(αT: Temperature Coefficient)

(duty cycles):0.01%

• Fast response time:

typically less than 1.0ps
from 0 Volts to BV min

• Excellent clamping

capability

• Typical failure mode is

short from over-specified
voltage or current

• Whisker test is conducted
based on JEDEC
JESD201A per its table 4a

and 4c
