Surface-Mount Ambient Light Sensing Photodiode from Vishay

The TEMD6200FX01 utilizes Vishay's exclusive infrared filtering epoxy technology to match the spectral sensitivity of the human eye with minimal sensitivity to light beyond the visible range. For consumer electronics, the device reduces power consumption by turning on keypad backlights only in low ambient conditions, and controlling LCD display brightness to optimize viewing based on ambient light.

Designed and qualified according to AEC-Q101 for automotive applications, the TEMD6200FX01 enables automatic headlight control, tunnel sensors, and displays that adjust automatically to changes in ambient brightness. The sensor also serves as an environmentally friendly alternative to cadmium-based photo resistors, the elimination of which has been mandated by RoHS legislation.

The device offers an angle of half sensitivity of ±60°, a radiant sensitive area of 0.3 mm2, and a peak sensitivity of 540 nm. Good lot-to-lot repeatability over the extended operating temperature range of -40°C to +100°C allows customers to eliminate calibration steps in their manufacturing process.

To enable a floor life of 168 hours without concern for absorption, the TEMD6200FX01 offers a moisture sensitivity level (MSL) of 3, in accordance with J-STD-020. The device is lead (Pb)-free and provides lead-free processing capability in accordance with RoHS 2002/95/EC and WEEE 2002/96/EC.

Samples and production quantities of the TEMD6200FX01are available now, with lead times of four to six weeks.
