About this manual

The SFH 401 series is a GaAs infrared emitting diode designed for applications such as IR‑remote control, industrial electronics, and light‑reflecting switches. It features a hermetically sealed glass lens in a TO‑18 package and offers both narrow‑beam and wide‑beam radiant intensity options.

Key performance data include a peak emission wavelength of 950 nm, forward voltage around 1.30 V at 100 mA, and a breakdown voltage of 30 V. The device provides high radiant intensity (up to 20 sr) and low capacitance (40 pF), making it suitable for fast modulation and reliable operation over a wide temperature range.
