TEMT3700 is a high sensitivity, high speed silicon NPN phototransistor produced by Vishay.
The TEMT3700 is a high‑speed silicon NPN epitaxial planar phototransistor offered in a miniature PL‑CC‑2 surface‑mount package. It features an extra‑wide viewing angle (±60°), a water‑clear epoxy lens for visible and near‑infrared sensitivity, and fast response times, making it suitable for miniature switches, counters, encoders, and position sensors.
The datasheet lists absolute maximum ratings such as a collector‑emitter voltage of 70 V, collector current up to 50 mA, and a total power dissipation of 100 mW. Typical electrical characteristics include a collector dark current of 1.2 µA, a peak collector capacitance of 3 pF, and a peak spectral sensitivity at 830 nm. Mechanical dimensions, solder‑pad layout, and environmental compliance information are also provided.
