Temperature Range: Parametrical/Functional Range

STPM098C is in LOOP ON mode. No damage affects STPM098C and no wrong operation takes place. All static

and dynamic parameters stay within specification limits.

Temperature Range: Critical OT Range

STPM098C is set into SAFE STATE mode. No damage affects STPM098C and no wrong operation takes place.

Static and dynamic parameters may deviate from specification limits.

Exposure to critical OT conditions for extended periods may affect device reliability.
