The PC364 is a phototransistor manufactured by Sharp Microelectronics. It is an optoelectronic device that combines a photodiode and a transistor in a single package. When light shines on the photodiode, it generates a current that triggers the transistor to conduct, allowing current to flow between the collector and emitter. This makes it useful for detecting light and converting it into an electrical signal.

Technical Specifications

The PC364 has key specifications including the collector-emitter breakdown voltage, collector current, and light current. The collector-emitter breakdown voltage (VCEO) specifies the maximum voltage that can be applied between the collector and emitter without causing breakdown. The collector current (IC) is the maximum current that can flow through the transistor. The light current (IL) is the current that flows when the phototransistor is illuminated. The operating temperature range is typically between -25°C to +85°C. The device is generally housed in a plastic package with clear or tinted epoxy for optimal light transmission.
