Description
The SMDJ-HR High Reliability series is designed specifically to
protect sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Uni-directional

Additional Information
■ VBR @TJ= VBR@25°C x (1+αT
x (TJ - 25))(αT:Temperature
Coefficient, typical value is
0.1%)
■ 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) (IPC/JEDEC J-STD-
609A.01)
■ Glass passivated chip junction
■ Fast response time: typically
less than 1.0ps from 0V to VBR
