CFD470

Fiber Optic PIN Photodiode

Technologies, Inc.

April, 2004

features

• High speed, low capacitance

• Optimized for fiber-optic

applications

• TO-18 header with plastic lens

description

The CFD470 contains a PIN silicon

photodiode mounted on a TO-18

header. The devices are designed

to self-align in the 0.228” (5.79mm)

bore of a standard fiber-optic

receptacle. Three crush ribs on the

outside of the case provide press-fit

installation and precise alignment.

The CFD470 is designed to interface

with multimode optical fibers from

50/125 to 200/300 microns.

storage temperature ...................................................................... -55°C to +115°C

operating temperature.................................................................... -40°C to +100°C

lead soldering temperature

reverse voltage ...........................................................................................100VDC

continuous power dissipation................................................................... 200mW
