Electrical characteristics
Maximum package power dissipation limits must be respected; low duty cycle pulse
techniques are used during test maintain TJ as close to TA as possible.
Unless otherwise stated, these specifications apply for - TA = 22 ±3°C, Vi = 15 V, Adjust Vi
above the start threshold before setting at 15 V; RT = 10 kΩ; CT = 3.3 nF.
