TSAL4400 Vishay Semiconductor EMITTER IR 940NM 100MA RADIAL

The part number TSAL4400 from Vishay Semiconductor refers to an infrared (IR) emitter. Here's a breakdown of its details:


  • Manufacturer: Vishay Semiconductor
  • Type: EMITTER IR (Infrared Emitter)
  • Wavelength: 940nm
  • Current Rating: 100mA (milliamperes)
  • Package: Radial

This IR emitter is designed to emit infrared light at a wavelength of 940nm. The 940nm wavelength falls within the near-infrared spectrum, and is commonly used in various applications such as remote controls, proximity sensors, and other systems that rely on infrared communication or sensing.

The 100mA current rating suggests the maximum forward current that the IR emitter can handle while emitting light within its specified range.

The radial package indicates the physical form and mounting style of the device. It typically refers to a leaded package where the leads are arranged in a radial pattern, allowing for through-hole mounting on a PCB.

Overall, the TSAL4400 IR emitter is designed for applications where infrared light emission at a specific wavelength, in this case 940nm, is required, such as in infrared communication, remote control systems, and various types of sensors.
