SWITCHING CURRENT. Switching current can be designed to increase or decrease with increasing temperature. ON VOLTAGE. Decreases as the temperature is raised. UNSPECIFIED PARAMETERS RATE EFFECT. As the rate at which voltage is applied to the diode dV increases, the voltage required to switch the diode decreases: dt A typical plot of this is as follows: A Vs Voltage required a Tektronix 575 curve tracer. to switch Applied voltage should be 10 volts above the nominal Vs with tk the diode series resistor, More accurate test procedures are availalbe from A.P.D. | T on and T off Typical Circuits are 470K 470KQ - A\/\/- | | | | D.U.T. t 1 T 01 1 dV 1 10 400 ACRO s00v ak |, , dt te, dog 4 005uf The shape of the above can be controlled and the diode can be de- 202, DUT S200 CRO signed with no change up to 10 V/us. o HIGH CURRENT ON IMPEDANCE A typical on impedance value In above circuit typical values of T on and T off are at 5 amps for the diode is .2 ohms, using a 575. curve tracer.
