Abstract
Transient overvoltage suppression is provided by discharging through a Metal Oxide Varistor (MOV) and Silicon Controlled Rectifier (SCR) which are connected in series between power supply lines. The SCR has a gate that receives a trigger signal generated by a triggering circuit coupled to the power supply lines. A trigger voltage of the triggering circuit is set by a Transil™ avalanche diode.
