Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. For guaranteed performance limits and associated test conditions, see
the Electrical Characteristics tables.
Note 2: To ensure constant junction temperature, low duty cycle pulse testing is used.
Note 3: Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for TA = TJ = 25°C.
Note 4: The maximum allowable power dissipation is a function of the maximum junction temperature TJ(MAX), the junction-to ambient thermal resistance θJ-A and the
ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is calculated using:
P(MAX) = TJ(MAX) - TA
θJ - A
Where the value of the junction-to-ambient thermal resistance are as follows: 195°C/W for TO-92 (N), 110°C/W for SOT-89 (L) and 220°C/W for 5 lead SOT-23.
