hfd3002 silicon pin photodiode outline dimensions in inches (mm) description the hfd3002 pin photodiode is designed for high speed use in fiber optic receivers. it has a large area detector, providing efficient response to 50-1000 m diameter fibers at wavelengths of 650 to 950 nanometers. it is designed to be used with fiber optic receptacles which align its optical axis with the axis of the optical fiber by referencing the precision outside diameter of the window can. the hfd3002s metal case is electrically isolated from anode and cathode terminals to enhance the emi/rfi shielding, increasing sensitivity and speed. it is also available in special active device receptacles, electrically isolated from their receptacles to improve sensitivity. the receptacle acts as a shield to improve the sensitivity/dark current specifications of the connectorized device. features electrically isolated from to-46 case low capacitance high speed: t2 = 30 ns max. at v? = 5 v; 10 ns max. at v? = 15 v high responsivity fiber001.dim fiber003.tif pinout 1. anode 2. cathode 3. case (ground) notes 1 anode and cathode isolated from case. 2 chip has 0.03 in.

hfd3002 silicon pin photodiode description catalog listing order guide HFD3002-002 standard silicon pin photodiode, metal to-46 case this package is also available in special interface receptacles for interfacing to standard fiber optic cables. the inherent design of this component causes it to be sensitive to electrostatic discharge (esd). to prevent esd-induced damage and/or degradation to equipment, take normal esd precautions when handling this product. c a u ti o n fiber interface honeywell detectors are designed to interface with multimode fibers with sizes (core/cladding diameters) ranging from 50/125 to 200/230 microns. honeywell performs final tests using 100/140 micron core fiber. the fiber chosen by the end user will depend upon a number of application issues (distance, link budget, cable attenuation, splice attenuation, and safety margin). the 50/125 and 62.5/125 micron fibers have the advantages of high bandwidth and low cost, making them ideal for higher bandwidth installations. the use of 100/140 and 200/230 micron core fibers results in greater power being coupled by the transmitter, making it easier to splice or connect in bulkhead areas. optical cables can be purchased from a number of sources. rise/fall time vs reverse bias voltage fig. 1 fiber033.gra package capacitance vs reverse bias voltage fig. 2 fiber034.g r spectral responsivity fig. 3 fiber101.gra dark leakage current vs temperature fig. 4 fiber036.g r honeywell reserves the right to make changes in order to improve design and supply the best products possible. 252 h
