Transient Voltage Suppressors - SMBJ Series

Features

• For surface mounted applications to optimize board space

• Very fast response time

• Halogen free and RoHS compliant

• Low incremental surge resistance

• Optimized for LAN protection applications

• Matte tin lead–free Plated

• Halogen ree and RoHS compliant

• Typical I

less than 1µA above 10V

• ESD protection of data lines in accordance with IEC 1000-4-2 (IEC801-2)

• EFT protection of data lines in accordance with IEC 1000-4-4 (IEC801-4)

• 600W peak pulse power capability with at 10/1000μs waveform,repetition

rate (duty cycle): 0.01%

• High temperature soldering : 260°C/ 40 seconds at terminals

The SMBJ series is designed specically to protect sensitive electronic equipment from voltage transients induced by lightning

and other transient voltage events.
