Thyristor TSPD 320V 32A 2-Pin SMB T/R
Manufacturer Part #: TISP4395M3BJR-S
Alternate Part #: TISP4395M3BJR-S
These devices are designed to limit overvoltages on the telephone line. A single device provides 2-point protection and is typically used for the protection of 2-wire telecommunication equipment. Combinations of devices can be used for multi-point protection. 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.These medium (M) current protection devices are in a plastic package SMBJ (JEDEC DO-214AA with J-bend leads) and supplied in embossed tape reel pack.
