SMCJ70A

ESD 抑制器/TVS 二极管 70Vr 1500W 13.3A 5% UniDirectional

Surface Mount – 1500W > SMCJ series

The SMCJ70A SMCJ series is designed specifically to protect

sensitive electronic equipment from voltage transients

induced by lightning and other transient voltage events.

SMCJ70A  Applications

TVS 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.

• 1500W peak pulse power

capability at 10/1000μs

waveform, repetition rate

(duty cycles):0.01%

• Excellent clamping

capability

• Low incremental surge

resistance

• Typical IR less than 1μA

when VBR min>12V

• For surface mounted

applications to optimize

board space

• Low profile package

• Built-in strain relief

• 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

• IEC-61000-4-2 ESD

30kV(Air), 30kV (Contact)

• ESD protection of data

lines in accordance with

IEC 61000-4-2

lines in accordance with

IEC 61000-4-4

• Fast response time:

typically less than 1.0ps

from 0V to BV min

• Glass passivated chip

junction

• High temperature

to reflow soldering

guaranteed: 260°C/40sec

• VBR @ TJ

= VBR@25°C

x (1+αT x (TJ

- 25))

(αT:Temperature

Coefficient, typical value

is 0.1%)
