UM4901中文资料HF-UHF Medium & High Power PIN Diodes数据手册Microchip规格书

描述 Description

The UM4000 and UM4900 series features high power PIN diodes with long carrier lifetimes and thick I-regions. They are especially suitable for use in low distortion switches and attenuators in HF through S band frequencies. While both series are electrically equivalent the UM4900 series have higher power ratings due to a shorter thermal path between the chip and package. High charge storage and long carrier lifetime enable high RF levels to be controlled with relatively low bias current. Similarly peak RF voltages can be handled well in excess of applied reverse bias voltage.

简介

UM4901属于分立半导体产品的二极管-射频。由制造生产的UM4901二极管 - 射频射频二极管是一种双端子半导体器件，只允许一个方向通过电流，而限制反方向的电流。该系列器件用于射频匹配电路以进行电子调谐。二极管类型包括 PIN 型、肖特基型和标准型，反向电压范围为 1 至 15,000 V，电流范围为 10 mA 至 20A。
