Axial Leaded – 500W > SAC series

RoHS

SAC Series

Description

Uni-directional

The SAC Series is designed specifically to protect sensitive

electronic equipment from voltage transients induced by

lightning and other transient voltage events.

Features

• Glass passivated chip

junction in DO-15

Package

• EFT protection of data

lines in accordance with

IEC 61000-4-4 (IEC801-4)

• 500W peak pulse power

capability at 10/1000μs

waveform, repetition rate

(duty cycles):0.01%

• Fast response time:

typically less than 1.0ps

from 0 Volts to BV min

•Typical failure mode is

short from over-speciﬁed

voltage or current

• Low incremental surge

resistance

• High temperature

soldering guaranteed:

260°C/40 seconds /

0.375”,(9.5mm) lead

length, 5 lbs., (2.3kg)

tension

• Plastic package has
