Ultra High Speed Photodetector
Ultra High Speed Photodetector
The AEPX Series of photodiodes is offered in a range of small active area sizes
suitable for high frequency optic applications. These photodetectors take
advantage of an epitaxial structure to achieve good high frequency response at
operating voltages as low as 5 volts. The detectros may also be operated at higher
bias levels up to 20 volts to achieve extremely fast pulsed response.
Electrical / Optical Specifications
Characteristics measured at 22°C (±2) ambient and a reverse bias of 5 volts,
unless otherwise stated.
