The TISP4070J3BJR-S from Bourns is a bidirectional thyristor overvoltage protector belonging to the TISP4xxxJ3BJ series. Designed for precise and stable voltage limiting, it features an ion-implanted breakdown region and low voltage overshoot under surge conditions. This device is specifically engineered for transformer center tap (ground return) overvoltage protection, enabling GR-1089-CORE compliance on data transmission lines with DC power feeding.
Key electrical specifications include a typical breakdown voltage (V(BO)) of 70V and an off-state voltage (VDRM) of 58V. It can handle significant surge currents, with a typical peak pulse current of 200A for a 10/1000 μs waveform (GR-1089-CORE) and up to 1000A for a 2/10 μs waveform. The device also features a high holding current (IH) of 150mA, which allows for protection of data lines with DC power feed and ensures the device resets following a disturbance.
Packaged in an SMB (DO-214AA) surface-mount case, the TISP4070J3BJR-S is suitable for rugged applications. Its design allows signal voltages up to VDRM without clipping, limiting voltages above VDRM to the breakover voltage level. When sufficient current flows, the device switches to a low voltage on-state, diverting the overvoltage current. It then switches off when the diverted current falls below the holding current level, restoring normal system operation.
This overvoltage protector is rated for international surge waveforms and is UL recognized. It is well-suited for protecting exposed applications exceeding TIA-968-A standards and is designed for transformer coupled lines where total ground return current can be substantial.
