High-speed protection devices

13 June 2018 Circuit & System Protection

The high-speed protector (HSP) models of Bourns’ TBU product range are circuit protection devices constructed using MOSFET semiconductor technology. When placed in series with a signal line, the TBU HSP monitors the current flowing through the line. If the current exceeds a preset level, the device triggers, providing an effective barrier to high voltages and currents.

The HSP begins protecting in less than 1 s, once line current exceeds the TBU device’s trigger current. When in the protected state, it restricts line current to less than 1 mA typically, and blocks voltages up to the maximum voltage rating of the device. After the surge, the TBU ­automatically resets itself when the voltage across the device falls to a settable level or below.
