Alpha is always less than 1 for a common base configuration.
TRANSISTOR RUGGEDNESS.—Transistors are generally more rugged mechanically than
electron tubes. They are susceptible to damage by electrical overloads, heat, humidity, and radiation.
Unless you are careful, damage can occur during maintenance.
DAMAGE PREVENTION.—To prevent damage and avoid electrical shock, use the following
precautions when working on transistorized equipment:
Check your test equipment and soldering irons for leakage current from the power source. If
leakage current exists, use an isolation transformer to eliminate the current.
