The ZSPT-Z2012B-10-Z3 with 0805 Phototransistors ROHS is a surface-mount, light-sensitive semiconductor component manufactured by Chau Light. The component is made of NPN silicon material and is available in a compact 0805 package. It is designed to detect the presence of optical signals, making it ideal for applications such as light- or motion-sensing, photoelectric arrays, and light-barrier circuits. Its RoHS compliance and low on-resistance further reduce power consumption, making it suitable for low-voltage, low-power designs. This component comes with a wide operating temperature range, making it suitable for a variety of applications.
