FEATURES

CB429

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.
