Absolute Maximum Ratings(2)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.

Notes:
2. These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
3. These ratings are based on a maximum junction temperature of 150 °C.
These are steady-state limits. ON Semiconductor should be consulted on applications involving pulsed or low-
duty cycle operations.
