Transistor is a basic semiconductor device that control current, which can also be used as a non-contact switch.

The transistors are silicone planar epitaxial NPN type transistors. The transistors are specially designed for high-speed switching applications and feature useful current gain over a wide range of collector current low leakage currents and low saturation voltages.
