SMBJ18CA

Transient Voltage Suppressor SMBJ SERIES Description SMBJ Series transient voltage suppressors are excellent overvoltage protective devices. The Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. SMB (DO-214AA) Features Mechanical Characteristics                Excellent clamping capability Low leakage current High surge capability Glass passivated chip Epoxy resin package Built-in strain relief Will not fatigue RoHS Compliant Fast response time: typically less than 1.0ps from 0 Volts to VBR min Package: SMB plastic package. Lead Finish: Matte Tin Case Material: Epoxy Molding Compound.
