Peak inverse Voltage
Peak inverse voltage is important parameter in the design of rectifier circuit. PIV is the maximum voltage that appears across the device during its blocking state. Hence it is applied to the SCR in the reverse direction. It is the amount of voltage the SCR can withstand in the reverse direction without having current flow.
Gate trigger current: The maximum value of gate current required to switch the device from the off state to the on state under specified conditions. The designer should consider the maximum gate trigger current as the minimum trigger current value that must be applied t the device in order to assure its proper triggering.
