tpb series ? bidirectional crowbar protection. voltage range: from 62 v to 270 v. holding current : i h = 150ma min. repetitive peak pulse current : i pp = 100 a, 10/1000 m s. ul recognized file # e136224 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. description schematic diagram trisil tm october 1998 - ed: 6a complies with the following standards: peak surge voltage (v) voltage waveform ( m s) current waveform ( m s) admissible ipp (a) necessary resistor ( w ) ccitt k20 4000 10/700 5/310 100 - vde0433 4000 10/700 5/310 100 - vde0878 4000 1.2/50 1/20 100 - iec-1000-4-5 level 4 level 4 10/700 1.2/50 5/310 8/20 100 100 - - fcc part 68, lightning surge type a 1500 800 10/160 10/560 10/160 10/560 200 100 - - fcc part 68, lightning surge type b 100 5/320 5/320 25 - bellcore tr-nwt-001089 first level 2500 1000 2/10 10/1000 2/10 10/1000 500 100 - - bellcore tr-nwt-001089 second level 500 2/10 2/10 500 - cnet l31-24 4000 0.5/700 0.8/310 100 - 1/5
