TISP4CXXXH3BJ overvoltage protector series tisp4c125h3bj thru tisp4c395h3bj low capacitance bidirectional thyristor overvoltage protectors description ion-implanted breakdown region - precise and stable voltage - low voltage overshoot under surge - low off-state capacitance this device is designed to limit overvoltages on the telephone line. overvoltages are normally caused by a.c. power system or l ightning flash disturbances which are induced or conducted on to the telephone line. a single device provides 2-point protection and is typica lly used for the protection of 2-wire telecommunication equipment (e.g. between the ring and tip wires for telephones and modems). combinations of devices can be used for multi-point protection (e.g. 3-point protection between ring, tip and ground). the protector consists of a symmetrical voltage-triggered bidirectional thyristor. overvoltages are initially clipped by breakd own clamping until the voltage rises to the breakover level, which causes the device to crowbar into a low-voltage on state. this low-voltage on s tate causes the current resulting from the overvoltage to be safely diverted through the device. the high crowbar holding current prevents d.c. latchup as the diverted current subsides. please contact your bourns representative if the protection voltage you require is not listed. how to order device symbol smb package (top view) rated for international surge wave shapes wave shape standard i ppsm a 2/10 gr-1089-core 500 10/160 tia-968-a 200 10/700 itu-t k.20/21/45 150 10/560 tia-968-a 100 10/1000 gr-1089-core 100 md-smb-004-a r1 2t t r sd-tisp4xxx-001-a *rohs directive 2002/95/ec jan 27 2003 including annex device package carrier marking code std. qty.
