The Bourns TISP4240M3AJR-S is a bidirectional thyristor designed for overvoltage protection in telecommunication equipment. It operates by clipping overvoltages and then crowbarring into a low-voltage on-state to divert surge current.
Key electrical specifications include an 180V off-state voltage and a 240V breakover voltage. It can handle a peak pulse current of 220A for an 8/20µs waveform and 50A for a 10/1000µs waveform. The device has a low on-state voltage of 3V and a holding current of 150mA.
This thyristor protector is housed in a compact DO-214AC (SMA) surface-mount package, suitable for applications requiring space efficiency. It is designed to limit overvoltages caused by lightning or power system disturbances on telephone lines, providing 2-point protection between Tip and Ring wires.
The TISP4xxxM3AJ series offers various voltage variants and is rated for international surge waveforms, including ITU-T K.20/21 and IEC 61000-4-5.
