Bourns TISP4040L1BJRS Overvoltage Protector

The TISP4040L1BJRS is a bidirectional overvoltage protector designed for low voltage digital telecommunication lines, including ISDN and xDSL systems. It features very low capacitance, high peak current handling, and compliance with standards such as FCC Part 68 and ITU-T K.20/45/21. The device provides two-point line signal level protection by clipping overvoltage pulses and diverting current safely through a symmetrical, voltage-triggered thyristor. Available in SMA and SMB packages, it is UL recognized and suitable for transformer windings and low voltage electronics protection in telecommunications infrastructure.
