hsmp-381z low distortion attenuator rf pin diodes in surface mount sod-323 package data sheet features ? 2 leads surface mount package ? low distortion attenuating ? microwave frequency operation ? tape and reel options available ? low failure in time (fit) rate ? msl1 & lead free description/applications avago technologies hsmp-381z is designed for low dis - tortion attenuator applications. it is housed in a low cost, industrial standard surface mount package - sod-323. this package ofers customers who already use them in sot- 23 and sot-323 packages, a logical transition to a smaller package outline to accommodate end product design with limited board space. the hsmp-381z has low distortion and high ip3 charac - teristics. the device can operate in microwave frequen - cies and suitable to be used as attenuating circuits in infrastructure and catv applications. a spice model is not available for pin diodes as spice does not provide for a key pin diode characteristic -- carrier lifetime. package marking and pin connections note: package marking provides orientation and identifcation k = device code ? = month code indicates the month of manufacture k ? cathode anode
