Description

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

Features

• For surface mounted

applications in order to
optimize board space

• Low prole package

• 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

15kV(Air), 8kV (Contact)

• ESD protection of data

lines in accordance with
IEC 61000-4-2 (IEC801-2)

• EFT protection of data

lines in accordance with
IEC 61000-4-4 (IEC801-4)

• Built-in strain relief

•

VBR @TJ= VBR@25°C × (1+αT

x (TJ - 25))

(αT: Temperature Coefficient)

• Glass passivated chip

junction

• 3000W peak pulse power

capability at 10/1000μs
waveform, repetition rate
(duty cycles):0.01%

• Fast response time:

typically less than 1.0ps

from 0V to BV min

• Excellent clamping

capability

• Low incremental surge

resistance

• Typical I

less than 2µA

R

above 12V

• High temperature

soldering guaranteed:
260°C/40 seconds at
terminals

• Plastic package has

underwriters laboratory
flammability 94V-O

• Meet MSL level1, per

J-STD-020, LF maximum
peak of 260°C

• Matte tin lead–free plated

• Halogen free and RoHS

compliant

Applications

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

bus and other vulnerable circuits used in Telecom,

CC

Computer, Industrial and Consumer electronic applications.
