<p><strong>宾夕法尼亚、MALVERN</strong><span><span> </span>—<span> </span></span><strong>2021年2月19日</strong><span><span> </span>—<span> </span></span><span>日前</span><span>，Vishay Intertechnology, Inc.（NYSE 股市代号：VSH）</span><span>宣布，推出新款可见红外高感</span><span>光度高速硅</span><span>PIN</span><span>光电二极管</span><span>-</span><span>--</span><a href="http://www.vishay.com/ppg?80218"><span>VEMD8081</span></a><span>，扩充光电二极管产品组合。Vishay Semiconductors<span> </span></span><a href="http://www.vishay.com/ppg?80218"><span>VEMD8081</span></a><span>采用矩形4.8mm x 2.5mm</span><span>顶视表面贴封装，厚度薄至</span><span>业内领先的</span><span>0.48mm，</span><span>典型反向光电流为</span><span>33 µA</span><span>，提高可穿戴设备和医疗应用生物传感器性能。</span></p>
<p><span>VEMD8081在相同封装尺寸条件下，反向光电流比其前身</span><span>VEMD8080</span><span>大</span><span>15 %</span><span>，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</span><span>LED</span><span>电流延长电池寿命。</span></p>
<p><span>VEMD8081</span><span>位于两个绿色脉动</span><span>LED</span><span>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。</span><span>VEMD808</span><span>1</span><span>矩形形状</span><span>最大化</span><span>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</span><span>光</span><span>和红外发射器，器件适用于医疗监护仪的SpO2测量。</span></p>
<p><span>VEMD8081</span><span>高灵敏度</span><span>感光面积达</span><span>5.4 mm²</span><span>，</span><span>利用</span><span>Vishay</span><span>成熟的晶圆技术，可在较宽光谱范围内，检测</span><span>350 nm</span><span>至</span><span>1100 nm</span><span>可见光和近红外辐射。器件开关速度快，容值低至</span><span>50 pF</span><span>，适用于高采样率。</span></p>
<p><span>VEMD8081</span><span>半感光角为</span><span>± 65°</span><span>，工作温度</span><span>40 °C</span><span>至</span><span>+85 °C</span><span>，峰值灵敏度波长为</span><span>840 nm</span><span>。光电二极管符合</span><span>RoHS</span><span>和</span><a href="http://www.vishay.com/doc?99912"><span>Vishay</span></a><a href="http://www.vishay.com/doc?99912"><span>绿色</span></a><span>标准，无卤素，</span><span>潮湿敏感度等级</span><span>（</span><span>MSL</span><span>）</span><span>达到</span><span>J-STD-020</span><span>标准</span><span>3</span><span>级</span><span>，可在车间存放</span><span>168</span><span>小时。</span></p>
<p><span>VEMD8081</span><span>现可提供样品并已实现量产，供货周期为</span><span>1</span><span>0</span><span>周。</span></p>
