The SMCJ series is designed specifically to protect sensitive electronic
equipment from voltage transients induced by lightning and other transient
voltage events
For surface mounted applications in order to optimize board space
Low leakage
Uni and Bidirectional unit
Glass passivated junction
Low inductance
Excellent clamping capability
Typical I
R less than 1A above 11V
1500W Peak power capability at 10 × 1000µs waveform Repetition
rate (duty cycle):0.01%
Fast response time: typically less than 1.0ps from 0 Volts to V min
High Temperature soldering: 260°C/40 seconds at terminals

Plastic package has Underwriters Laboratory Flammability 94V-0
Matte tin lead–free Plated
Halogen free and RoHS compliant
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)
TVS devices are ideal for the protection of I/O interfaces, V
bus
and other vulnerable circuits used in Telecom, Computer, Industrial
and Consumer electronic applications.
