SMP1302-085LF分立半导体产品的二极管-射频规格书PDF中文资料

SMP1302-085LF属于分立半导体产品的二极管-射频。由美国思佳讯公司制造生产的SMP1302-085LF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。

描述 Description

The SMP1302-085LF is a surface mountable, low capacitance silicon PIN diode designed as a shunt connected PIN diode for high power, high volume switch and attenuator applications from 10 MHz to beyond 6 GHz.

Maximum resistance at 100 mA is 1.5 Ω and maximum capacitance at 30 V is 0.35 pF. The combination of low junction capacitance, low parasitic inductance, low thermal resistance, and nominal 50 μm I-region width, makes the SMP1302-085LF useful in large signal switches and attenuator applications.

The device has a 2.8 W dissipation power rating, making it capable of handling more than 140 W Continuous Wave (CW) and 500 W peak (1 μs pulse, 1 percent duty cycle) in a shunt-connected transmit/receive (T/R) switch.
