Phototransistors. A phototransistor is a bipolar transistor whose base-collector junction is exposed to light. When a photon is absorbed in the junction region, an electron-hole pair is created and the photocurrent produced is then amplified as in the normal transistor. Shown here are NPN silicon phototransistors manufactured by Motorola. The outside diameter of the TO-18 package shown is 5.4 mm. | |
