TPB series

The TPB series is designed as one kind of TRISIL devices,it is especially designed for protecting sensitive telecomminication equipment against lightning and transient voltages induced by AC power lines.They are available in the CB429 axial package.The TRISIL devices provide bidirectional protection by crowbar action.Their characteristic response to transient overvoltages makes them particularly suited to protect voltage sensitive teltcommunication equipment.

Features of the TPB series are:(1)bidirectional crowbar protection;(2)voltage range:from 62 V to 270 V;(3)holding current:Ih=150 mA min;(4)repetitive peak pulse current:Ipp=100 A,10/1000 us;(5)UL recognized file #E136224.

The absolute maximum ratings of the TPB series can be summarized as:(1)power dissipation on infinite heatsink:5 W;(2)peak pulse current:100 and 150 and 500 A;(3)non repetitive surge peak on-state current:50 A;(4)value for fusing:25 A2S;(5)critical rate of off-state voltage;(6)storage temperature range:-55 to +150;(7)maximum junction temperature:150;(8)maximum lead temperature for soldering during 10s at 5mm for case:230;(9)junction to leads:20/W;(10)junction to ambient on printed circuit:75/W.
