The maximum operating temperature range for the 2N5416 is -55°C to 150°C.
Yes, the 2N5416 can be used as a switch, but it's not recommended due to its relatively low current handling capability (500mA) and high saturation voltage (Vce(sat) = 0.5V). A more suitable transistor for switching applications would be a power transistor like the 2N3055.
To ensure the 2N5416 is fully turned off, the base-emitter voltage (Vbe) should be less than 0.5V. This can be achieved by applying a negative voltage to the base with respect to the emitter or by using a pull-down resistor to ground.
The maximum collector-emitter voltage (Vce) that the 2N5416 can handle is 30V.
The 2N5416 is not suitable for high-frequency applications due to its relatively high transition frequency (fT) of 100MHz. For high-frequency applications, a transistor with a higher fT, such as the 2N3904, would be more suitable.
