SMTPA220 General Description

These Trisil series have been designed to protect telecommunication equipment against lightning and transient induced by AC power lines. They are available in SMA, SMB and DO-15 packages. Benefits Trisils are not subject to ageing and provide a fail safe mode in short circuit for a better protection.
