Die Construction Improves Radiant Intensity of 940nm IR Emitter

Vishay has used a unique die construction to produce high-power, high-speed 940nm Infra-Red (IR) emitters.

As a result the VSMB2000X01 surface-mount IR emitter, with an angle of half intensity of ±12°, features significantly higher radiant intensity of emitted light and power compared to standard emitter technologies.

The VSMB2000X01 features a small surface-mount package, measuring 2.3mm x 2.3mm x 2.8mm. It reliably produces high-power high-radiant- intensity IR, with a peak wavelength of 940nm.

The emitter is built using GaAlAs technology and moulded in a clear, untinted plastic package, including a 1.9mm lens. The device matches the VEMD20x0X01 diode and VEMT20x0X01 transistor detector series.

Vishay’s IR emitter technology is also available in 1.9mm (T¾) gullwing (VSMB2000X01), PLCC2 (VSMB3940X01) and 0805 (VSMB1940X01) surface-mount packages. All of these devices are qualified to the automotive AECQ101 standard.
