Revised: 02/23/17 I H I T I S I DRM V DRM V T +V -V +I -I V S Figure 1.3 V-I Characteristics SIDACtor electrical parameters are based on the following definition of conditions: Please refer to Figure 1.3 above related to many of the following terms: C O Off-state Capacitance -capacitance measured in off state @ 2 V bias and 1 MHz di/dt Rate of Rise of Current -maximum rated value of the acceptable rate of rise in current over time dv/dt Rate of Rise of Voltage -rate of applied voltage over time I S Switching Current -maximum current required to switch to on state I DRM Leakage Current -maximum peak off-state current measured at V DRM I H Holding Current -minimum current required to maintain on state I PP Peak Pulse Current -maximum rated peak impulse current I T On-state Current -maximum rated continuous on-state current I TSM Peak One-cycle Surge Current -maximum rated one-cycle AC current V S Switching Voltage -maximum voltage prior to switching to on state during 100 V/s surge V DRM Peak Off-state Voltage -maximum voltage that can be applied while maintaining off state V F On-state Forward Voltage -maximum forward voltage measured at rated on-state current V T On-state Voltage -maximum voltage measured at rated on-state current On state (also referred to as the crowbar condition ) is the low impedance condition reached during full conduction and simulates a short circuit. Off state (also referred to as the blocking condition ) is the high impedance condition prior to beginning conduction and simulates an open circuit. Electrical Parameters
