Vishay Intertechnology, Inc.（NYSE 股市代号：VSH）推出采用 0805 尺寸小型表面贴装封装、厚度为 0.85 mm 及简单两引脚连接的光电二极管环境光传感器，从而扩展了其光电产品系列。新型 TEMD6200FX01以类似人眼的方式响应灯光，从而可自动控制 LCD 亮度和键区的背光，并可实现诸多高级汽车驾驶方面舒适及安全的功能。
该TEMD6200FX01采用 Vishay 独特的红外滤波环氧树脂技术，该技术可使人眼的光谱敏感性与对超出可视范围的光线的最低敏感度相匹配。对于消费电子产品而言，该器件通过仅在极低的环境亮光条件下打开键区背光并控制 LCD 显示亮度以优化基于环境光的视觉，从而可降低功耗。
该TEMD6200FX01根据 AEC-Q101 标准设计并符合该标准，可实现自动前灯控制、隧道传感器及根据环境亮度自动调整显示，适合汽车应用。该传感器还成为基于镉的光敏电阻器的替代品，并符合 RoHS 规范、对环境友好。
该器件具有 ± 60° 的半灵敏度角度、0.3 mm2发光感应区域及 540 nm 的最高灵敏度。凭借在 -40°C 至 +100°C 更大工作温度范围内的出色批到批可重复性，确保客户无需在制造过程中进行校准。
Vishay Releases New Surface-Mount Ambient Light Sensing Photodiode in 0805-Sized Package with 0.85-mm Profile and Simple 2-Pin Connection
AEC-Q101-Qualified Device Reacts to Light like Human Eye for LCD Brightness Control and Automotive Applications
Vishay Intertechnology, Inc. (NYSE: VSH) has broadened its optoelectronics portfolio with the introduction of a photodiode-based ambient light sensor in a compact 0805-sized surface-mount package, featuring a small 0.85-mm profile and simple 2-pin connection. The new TEMD6200FX01 reacts to light like the human eye to allow automatic control of LCD brightness and keypad backlighting and to enable a number of advanced automotive driver comfort and safety features.
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.
