Dual-colour red and IR emitting diode saves space
Designed to save space in wearables and medical patient monitoring systems, a dual-colour red and IR emitting diode has been introduced by Vishay Intertechnology. The VSMD66694 features wavelengths of 660 (red) and 940nm (IR) in a compact 2x2x0.87mm package and is built on SurfLight technology for best-in-class radiant power of 9.5 and 8.5mW, respectively.
For space-constrained devices such as smart watches and fitness bands, the VSMD66694 can replace two leaded diodes with one component in a surface-mount package that can be easily combined with any custom-designed lens system. The device features a narrow spectral bandwidth of 20 at 660nm, and its balanced radiant power at red and IR wavelengths provides balanced signal levels for SpO2 and pulse rate monitoring.
The emitter released today provides fast switching times of 10ns and forward voltage down to 1.4V. Suitable for high pulse current operation to 1A at 100µs, the device features a ±60° angle of half-intensity and operates over a temperature range of -25 to +85°C. The VSMD66694 provides an MSL of 3 in accordance with J-STD-020 for a floor life of 168hrs, supports lead (Pb)-free reflow soldering and is RoHS-compliant, halogen-free and Vishay Green.
Samples and production quantities of the VSMD66694 dual-colour red and IR emitting diode are available now, with lead times of 10-12 weeks for large orders.
