2 N 3906 / MMBT3906 / PZTAbsolute Maximum Ratings (1) 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.

These ratings are based on a maximum junction temperature of 150°C. N P Gen These are steady-state limits. ON Semiconductor should be consulted on applications involving pulsed or low-duty cycle operations. eraThermal Characteristicsl-Purpose Values are at TA = 25°C unless otherwise noted.
