# IF\-D91 (Component)

## Description

Fiber Optic Photodiode Receiver – High\-speed silicon photodiode fiber optic receiver optimized for plastic optical fiber \(POF\) communication, industrial control, robotics, automotive electronics, and EMI/EMC\-immune data links\. Features a 400 nm to 1100 nm spectral response, making it compatible with 650 nm visible red LEDs and near\-infrared light sources\. Incorporates an internal micro\-lens and connector\-less package for efficient coupling to 1 mm PMMA plastic optical fiber, supporting data rates up to 100 Mbps\. Provides 60 nA typical reverse dark current, low junction capacitance, fast response time, and operates over a −40°C to \+85°C temperature range\. Housed in a through\-hole plastic fiber optic package\. This part is obsolete, with the IF\-D91B available as the direct replacement\.
