TISP4125J3BJR-S Description

Short technical summary and product information.

The Bourns TISP4125J3BJR-S is a bidirectional thyristor overvoltage protector designed to limit overvoltages on telecom lines. It features an ion-implanted breakdown region for precise and stable voltage protection with low voltage overshoot under surge conditions.

 

Key electrical specifications include a breakover voltage of 125 V, off-state voltage of 100 V, and a holding current of 150 mA. The device is rated for multiple surge waveforms: 1000 A (2/10 µs) per GR-1089-CORE, 800 A (8/20 µs) per IEC 61000-4-5, 400 A (10/160 µs) per TIA-968-A, 350 A (10/700 µs) per ITU-T K.20/21/45, 250 A (10/560 µs) per TIA-968-A, and 200 A (10/1000 µs) per GR-1089-CORE. Capacitance is 120 pF.

 

The device is housed in a surface mount DO-214AA (SMB) package and is UL recognized (File E215609) for international surge wave shapes. It is designed for transformer center tap (ground return) overvoltage protection and enables GR-1089-CORE compliance. The high holding current allows protection of data lines with DC power feed.
