PT501/PT510 is a phototransistor widely used in optoelectronic switches, optoelectronic counters, smoke detectors, and infrared applied systems. It features narrow acceptance angle, glass lens, and fast response time.
This document provides a datasheet for the SHARP PT501 and PT510 optoelectronic switches. It details physical dimensions, absolute maximum ratings, and electro-optical characteristics such as collector current, dark current, saturation voltage, sensitivity wavelength, and response time. The device is designed for applications including optoelectronic counters, smoke detectors, and infrared applied systems.
| Product Type | Optoelectronic switches, optoelectronic counters |
|---|---|
| Collector current (PT501) | 2.5 to 10 mA |
| Peak sensitivity wavelength | 800 nm |
| Operating temperature (PT501) | -25 to +125 °C |
| Collector-emitter voltage (PT501) | 45 V |
They are suitable for optoelectronic counters, smoke detectors, and infrared applied systems.
No, the PT501 does not have a base terminal, unlike the PT510.
