The SMP1302 series of plastic packaged, surface mountable, low capacitance (0.3 pF) silicon PIN diodes is designed for highvolume switch and attenuator applications from 10 MHz to beyond 2 GHz. These diodes are designed for use in low- distortion PI and TEE attenuators with low drive current (maximum resistance at 1 mA is 10 Ω) commonly used in TV distribution and cellular base station applications. The nominal 50 μm I region width, combined with a maximum resistance of 3 Ω at 10 mA, makes these diodes useful in large signal switch applications. The SMP1302 series provides single and dual diodes in a selection of plastic packages including SOT-23, SOD-323, small footprint SC-79, an ultralow inductance (0.2 nH) SOT-143 (SMP1302-017), and miniature SC-70. A four-diode array is available in an SOT-5 package (SMP1302- 027) designed for insertion in the commonly used four-diode PI attenuator circuits.
