Phototransistors

Marktech Optoelectronics Phototransistors are solid-state light detectors with internal gain designed to detect visible, ultraviolet, and near-infrared light. These silicon phototransistors offer unparalleled sensitivity, signal amplification, and versatility, making them indispensable for a wide range of applications across diverse industries. The phototransistors feature high precision, reliability, and exceptional performance, enabling light sensing and detection. These phototransistors are available with a broad spectral response, including the visible, UV, and near‑infrared regions. The phototransistors feature high sensitivity, enabled by internal gain, for stronger analog or digital output signals. Typical applications include optical encoders and interior light sensing within vehicle subsystems, consumer electronics and wearables, robotics, and industrial subsystems.
