Ultra High Speed Detectors (AEPX)

Ultra High Speed Detectors (AEPX) The AEPX Series of photodiodes is offered in a range of small active area sizes suitable for high frequency fibre 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 detectors 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 12 volts, unless otherwise stated.
