The maximum operating temperature range for the 2N1302 is -65°C to 150°C, although the recommended operating temperature range is -40°C to 125°C.
To ensure the 2N1302 is properly biased for linear operation, you should ensure that the base-emitter voltage (VBE) is between 0.6V and 0.8V, and the collector-emitter voltage (VCE) is at least 1V greater than the base-emitter voltage.
The maximum current handling capability of the 2N1302 is 500mA for the collector current (IC) and 50mA for the base current (IB).
To protect the 2N1302 from ESD, you should handle the device with an anti-static wrist strap or mat, and ensure that the device is stored in an anti-static package or bag.
Yes, the 2N1302 can be used as a switch, but it is not recommended due to its relatively low current handling capability and high saturation voltage. A more suitable transistor for switching applications would be a power transistor like the TIP120 or TIP122.
