Transient Voltage Suppression Diodes

Surface Mount – 1500W > SMCJ series

SMCJ Series

Uni-directional

Bi-directional

Description

RoHS

The SMCJ series is designed specifically to protect

sensitive electronic equipment from voltage transients

induced by lightning and other transient voltage events.

Features

• 1500W peak pulse power

capability at 10/1000μs

waveform, repetition rate

(duty cycles):0.01%

• Excellent clamping

capability

• Low incremental surge

resistance

• Typical I

less than 1μA

when V

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

• EFT protection of data

lines in accordance with

IEC 61000-4-4

Applications

TVS devices are ideal for the protection of I/O Interfaces,

bus and other vulnerable circuits used in Telecom,

Computer, Industrial and Consumer electronic

applications.

Additional Infomarion

• 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

• V

@ T

= V

@25°C

x (1+

T x (T

- 25))

(

T:Temperature

Coefficient, typical value

is 0.1%)

• Plastic package is

flammability rated V-0 per

Underwriters Laboratories

• Meet MSL level1, per

J-STD-020, LF maximun

peak of 260

• Matte tin lead–free plated

• Halogen free and RoHS

compliant

• Pb-free E3 means 2nd

level interconnect is

Pb-free and the terminal

finish material is tin(Sn)
