SMAJ Series
Description The SMAJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. Features typically less than 1.0ps from 0 Volts to VBR min less than 1A R above 12V soldering: 260C/40 seconds at terminals temperature coefficient capability
VBR = 0.1% x VBR@25C x T
applications to optimize board space Agency Approvals
