VDRM (Peak Off-state Voltage) : Maximum voltage that can be applied while maintaining OFF state.
IDRM (Leakage Current) : Maximum peak OFF-state current measured at VDRM (Peak OFF-state Voltage).
VS (Switching Voltage) : Maximum voltage prior to switching to ON state.
IS MAX (Switching Current) : Maximum current required to switch to ON state.
VT MAX (ON state Voltage) : Maximum voltage measured at rated ON state current.
IH MIN (Holding Current) : Minimum current required to maintain ON state.
CO MIN (Minimum OFF-state Capacitance) : Minimum capacitance measured in OFF state.
CO MAX (Maximum OFF-state Capacitance) : Maximum capacitance measured in OFF state.
IPP (Peak Pulse Current) : Maximum rated peak impulse current.
ITSM (Peak One-cycle Surge Current) : Maximum rated one-cycle AC current.
di/dt MAX (Rate of Rise of Current) : Maximum rated value of the acceptable rate of rise in current over time.
Switch to ON STATE :
V <= VS @ I <= IS MAX
Maintain ON STATE :
Von <= VT MAX @ Ion >= IH MIN
OFF STATE :
V <= VDRM @ I <= IDRM
