UL RECOGNIZED FILE # E136224
DESCRIPTION
The TPB 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 CB429 axial package.
TRISIL devices provide bidirectional protection by
crowbar action. Their characteristic response to
transient overvoltages makes them particularly
suited to protect voltage sensitive telecommunica-
tion equipment.
