Phototransistor Circuits: How to Build and Simulate

WebApplications of phototransistor. Phototransistors are used in a variety of applications. A light-operated relay circuit is The phototransistor Q 1 drives the BJT Q 2. When there is sufficient incident light on Q 1, transistor Q 2 is driven into saturation, and collector current through the relay coil energizes the relay. WebPNP phototransistors are current-operated devices that convert light into current when exposed to light. These devices are typically used in applications where current needs to be either stored or converted into voltage. PNP phototransistors have a higher resistance when in the dark, but this decreases as the intensity of light increases. tn shocks
