e3 Description
The SMAJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. Uni-directional Bi-directional
Features
• 400W Peak pulse power • Fast response time: capability at 10/1000µs typically less than 1.0ps waveform, repetition rate from 0 Volts to V min BR (duty cycle): 0.01% • Glass passivated junction • Excellent clamping • Low inductance
Agency Approvals
capability • High temperature • Typical I less than 1μA R to reflow soldering
Agency Agency File Number
