SNVS354B – JULY 2005 – REVISED MARCH 2013

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

All electrical characteristics having room temperature limits are tested during production with TA = TJ = 25°C. All hot and cold limits are

specified by correlating the electrical characteristics to process and temperature variations and applying statistical process control.

(2)

Device thermal limitations may limit usable range.
