SMDJ Series
Description
Uni-directional
The SMDJ series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
Features
• 3000W PPPM capability
at 10/1000μs waveform,
repetition rate (duty
cycles):0.01%
• Low incremental
surge resistance
• Typical IR less than 2μA when
VBR min>12V
Bi-directional
• For surface mounted
applications in order to
optimize board space
• High temperature to reflow
soldering guaranteed:
260°C/30sec
• VBR @TJ= VBR@25°C x (1+αT
x (TJ - 25))(αT:Temperature
