The mercury wetted relay provides a high speed repeated pulse to the D.U.T. 2. 100x scope probes are used, to allow high speeds and voltages. 3. The worst-case condition for static dv/dt is established by triggering the D.U.T. with a normal LED input current, then removing the current. The variable RTEST allows the dv/dt to be gradually increased until the D.U.T. continues to trigger in response to the applied voltage pulse, even after the LED current has been removed. The dv/dt is then decreased until the D.U.T. stops triggering. τRC is measured at this point and recorded. NOTE: This optoisolator should not be used to drive a load directly. It is intended to be a trigger device only. |
