TISP4070H3LM THRU TISP4115H3LM, TISP4125H3LM THRU TISP4220H3LM, TISP4240H3LM THRU TISP4400H3LM BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS TISP4xxxH3LM Overvoltage Protector Series TISP4xxxH3LM Overview This TISP device series protects central of ce, access and customer premise equipment against overvoltages on the telecom line. The TISP4xxxH3LM is available in a wide range of voltages and has a high current capability, allowing minimal series resistance to be used. These protectors have been speci ed mindful of the following standards and recommendations: GR-1089-CORE, FCC Part 68, UL1950, EN 60950, IEC 60950, ITU-T K.20, K.21 and K.45. The TISP4350H3LM meets the FCC Part 68 B ringer voltage requirement and survives the Type A and B impulse tests. These devices are housed in a through-hole DO-92 package (TO-92 package with cropped center leg).

Overvoltages are normally caused by a.c. power system or lightning ash disturbances which are induced or conducted on to the telephone line. A single device provides 2-point protection and is typically 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 breakdown 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 state causes the current resulting from the overvoltage to be safely diverted through the device. The high crowbar holding current helps prevent d.c. latchup as the diverted current subsides.
