Silicon Unidirectional Switches (SUS) KU121

Semiconductor Devices



Purpose:

Silicon Unidirectional Switches (SUS) KU121 can be applied in phase power regulators, thyristor actuators, inverters, threshold devices, working at half-wave voltage, and other control devices.

The device provides reliable start-up of all types thyristors.

The device is produced in different constructive variants: in package SOT23, TO-92 and in impackaged chip variant with aluminum or soldering pads for surface mounting on hybrid chips plate, as well as other variants.
