This release in:

MALVERN, Pa. — June 9, 2016 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new dual-color red and IR emitting diode designed to save space in wearable devices and medical patient monitoring systems. Offered in a compact 2 mm by 2 mm by 0.87 mm package, the Vishay Semiconductors VSMD66694 features wavelengths of 660 nm (red) and 940 nm (IR), and is built on SurfLight technology for best-in-class radiant power of 9.5 mW and 8.5 mW, respectively.

For space-constrained devices like 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 nm at 660 nm, 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 10 ns and forward voltage down to 1.4 V. Suitable for high pulse current operation to 1 A at 100 s, the device features a 60 angle of half intensity and operates over a temperature range of -25 C to +85 C. The VSMD66694 provides a moisture sensitivity level (MSL) of 3 in accordance with J-STD-020 for a floor life of 168 hours, supports lead (Pb)-free reflow soldering, and is RoHS-compliant, halogen-free, and Vishay Green.

Device Specification Table:

Color Red IR
Peak wavelength (nm) 660 940
Radiant power (mW) 9.5 8.5
Radiant intensity (mW/sr) 2.3 1.5
Spectral bandwidth (nm) 20 40
Power dissipation (mW) 161 119
Typ. forward voltage (V) 2.0 1.4

Samples and production quantities of the new dual-color red and IR emitting diode are available now, with lead times of 10 to 12 weeks for large orders.
