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

Excellent clamping capability
Low incremental surge resistance
Typical IR less than 1μA above 12V
For surface mounted applications to optimize board space
Low profile package
Typical failure mode is short from over-specified voltage or current
Whisker test
Built-in strain relief
Fast response time: typically less than 1.0ps from 0V to BV min
600W peak pulse power capability at 10x1000μs waveform, repetition rate (duty cycles):0.01%
Typical maximum temperature coefficient ΔVBR= 0.1% x VBR@25°C x ΔT
Glass passivated chip junction
High temperature soldering guaranteed: 260°C/40 seconds at terminals
Matte tin lead–free plated
Halogen free
