Ordering Information

Absolute Maximum Ratings(1), (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: 1.These ratings are based on a maximum junction temperature of 150°C. 2.These are steady-state li mits. ON Semiconductor should be consulted on applications involving pulsed or low- duty-cycle operations.
