The Bourns TISP4040L1AJR-S is a very low voltage bidirectional thyristor overvoltage protector. It is designed to limit overvoltages on digital telecommunication lines, typically caused by AC power system or lightning disturbances. This device provides 2-point protection and is suitable for protecting transformer windings and low voltage electronics.
Key electrical specifications include a nominal breakdown voltage of 40V (VDRM) and a nominal breakover voltage of ±40V (V(BO)). The device offers various peak pulse current ratings depending on the waveform, including 30A for a 10/1000 μs wave shape and 120A for an 8/20 μs wave shape. Its capacitance is typically 23pF.
The TISP4040L1AJR-S is housed in a DO-214AC (SMA) surface mount package, offering a compact solution for board placement. It is specified for standards such as ITU-T K.20, K.45, K.21, FCC Part 68, and GR-1089-CORE.
This thyristor operates by clipping overvoltages until the breakover level is reached, at which point it crowbars into a low-voltage on-state, diverting current safely. It switches off when the current falls below the holding current value.
