宾夕法尼亚、MALVERN — 2021年2月17日 — 日前,Vishay Intertechnology, Inc.(NYSE 股市代号:VSH)宣布,推出新款可见红外高感光度高速硅PIN光电二极管,扩充光电二极管产品组合。Vishay Semiconductors VEMD8081采用矩形4.8mm x 2.5mm顶视表面贴封装,高度低至业内领先的0.48mm,典型反向光电流为33 µA,提高可穿戴设备和医疗应用生物传感器性能。

VEMD8081在相同封装尺寸条件下,反向光电流比其前身VEMD8080大15 %,为设计人员提供直接替代器件,增加信号输出提高性能,或减小LED电流延长电池寿命。

VEMD8081位于两个绿色脉动LED之间,可在运动追踪器和智能手表等可穿戴设备中进行心率检测。光电二极管接收皮肤反射回来的光,将其转换为输出电流,器件提高了灵敏度,可进行更精确的测量。VEMD8081矩形形状最大化光电二极管感光区,消除一般正方形光电二极管浪费的面积。结合红光和红外发射器,器件适用于医疗监护仪的SpO2测量。

VEMD8081高灵敏度感光面积达5.4 mm²,利用Vishay成熟的晶圆技术,可在较宽光谱范围内,检测350 nm至1100 nm可见光和近红外辐射。器件开关速度快,容值低至50 pF,适用于高采样率。

VEMD8081半感光角为± 65°,工作温度40 °C至+85 °C,峰值灵敏度波长为840 nm。光电二极管符合RoHS和Vishay绿色标准,无卤素,潮湿敏感度等级(MSL)达到J-STD-020标准3级,可在车间存放168小时。

VEMD8081现可提供样品并已实现量产,供货周期为10周。

Vishay 是全球最大的分立半导体和无源电子元件系列产品制造商之一,这些产品对于汽车、工业、计算、消费、通信、国防、航空航天和医疗市场的创新设计至关重要。服务于全球客户,Vishay承载着科技基因——The DNA of tech.®  Vishay Intertechnology, Inc. 是在纽约证券交易所上市(VSH)的“财富1,000 强企业”。有关Vishay的详细信息,敬请浏览网站 www.vishay.com。
