SMDJ-HRA Series

Surface Mount – 3000W

Pb e3

RꢀHS

Description

The SMDJ-HRA High Reliability series is designed specifically to

protect sensitive electronic equipment from voltage transients

induced by lightning and other transient voltage events. These are

available with a variety of up-screening options for enhanced

reliability.

Uni-directional

Bi-directional

Features & Benefits

■ High reliability devices with

fabrication and assembly lots

traceability

■ Excellent clamping capability

■ Low incremental surge

resistance

■ Enhanced reliability screening

options are available in

reference to MIL-PRF-19500.

Refer to screen process table

for more detail on screening

options

■ Typical IR less than 2µA above

12V

■ HighTemperature soldering

guaranteed: 260°C/40 seconds

at terminals

Additional Information

■ Plastic package has

Underwriters laboratory

ﬂammability 94V-O

■ For surface mounted

applications in order to

optimize board space

■ Meet MSL level1, per

J-STD-020, LF maximun peak

of 260°C

■ Low proﬁle package

■ Built-in strain relief
