TPA SERIES
TRISIL™
F126
DESCRIPTION
The TPA series are TRISIL devices especially de-
signed for protecting sensitive telecommunication
equipment against lightning and transient voltages
induced by AC power lines. They are available in
the F126 axial package.
TRISIL devices provide bidirectional protection
by crowbar action. Their characteristic response
to transient overvoltages makes them particularly
suited to protect voltage sensitive telecommuni-
cation equipment.
