Abstract
The relay has two separate and identical power thyristors 210 and 211 connected in anti-parallel arrangement. The powerthyristors are each optically switched, lateral conduction devices and both are switched by illuminating their surface by reflected illumination from an LED 225. Each thyristor is provided with a respective control circuit which includes a MOSFET transistor 230-231, for clamping its respective thyristor gate whenever the voltage across the thyristor exceeds a given absolute value or whenever there is a high dV/dt transient across the thyristor. The control circuit for the control transistor includes a capacitance divider 236-239, one element of which is the distributed capacitance 238, 239 of the control transistor; a resistor 234, 235 and a zener diode 232, 233. The control circuit components may be integrated into the thyristor chips. Each of the two identical power chips and the LED chip are spaced from one another and mounted on an alumina substrate. <IMAGE>
