Notes:
a. Device Mounted with all leads soldered or welded to PC board.
b. Derate 9.52 mW/°C above 70 °C.
Exposure to Absolute Maximum rating conditions for extended periods may affect device reliability. Stresses above Absolute Maximum rating may cause permanent
damage. Functional operation at conditions other than the operating conditions specified is not implied. Only one Absolute Maximum rating should be applied at any
one time.
