HFD3855 HFD3855 Silicon PIN Photodiode FEATURES · Low capacitance · High speed: t² = 30 ns max. @ 5 V · Industry standard ST¨-LP fiber connector · Housing electrically isolated · Wave solderable FIBER209 FIBER209.TIF DESCRIPTION The HFD3855 HFD3855 PIN Photodiode is designed for high speed use in fiber optic receivers. It has a large area detector, providing efficient response to 50 - 1000 mm diameter fibers at wavelengths of 750 to 950 nanometers.The HFD3855 HFD3855 is comprised of an HFD3022 HFD3022 PIN photodiode which is mounted in a low profile ST¨ fiber optic connector. The ST¨ connector housing aligns the component's optical axis with the axis of the optical fiber. The HFD3855s case is electrically isolated from the anode and cathode terminals to enhance the EMI/RFI shielding which increases the sensitivity and speed. The metal ST¨ housing acts as a shield for the PIN photodiode component.

ABSOLUTE MAXIMUM RATINGS (Tcase = 25¡C unless otherwise noted) Storage temperature -40 to +100¡C Operating temperature -40 to +100¡C Lead solder temperature 240¡C for 3 min, 260¡C for 10 s Reverse voltage 110 V Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.

To prevent ESD-induced damage and/or degradation to equipment, take normal ESD precautions when handling this product. 390 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. h Honeywell reserves the right to make changes in order to improve design and supply the best products possible.
