NOTES:
(1) V(BR) measured at pulse width of 300µs sq. wave or equivalent
(2) Surge current waveform per Fig. 3 and derate per Fig. 2
(3) Junction capacitance measured at 1.0 MHZ and applied VR=0 volts
* V(BR) test current (IT) is 10 mA
*Application note: Due to the topology of the SMDA array the VRWM and V(BR) specifications also
apply to the differential voltage between any two data line pins.
