Currently Viewing:

The Broadcom TO124EATx is a TO-46 packaged avalanche photodiode (APD) device with a high-gain transimpedance amplifier (TIA) for use in fiber optic communication network applications supporting data rates up to 10.7 Gb/s and link distances up to 80 km. The APD/TIA is mounted into a TO-46 header and hermetically sealed with a lens cap. The APD chip is back-illuminated with 120um diameter surface integrated lens and designed with planar passivation for low dark current and the low breakdown voltage for low power consumption. The built-in TIA provides wideband, low noise amplification of signal current from a photo detector.


  • Built-in high speed, low noise TIA
  • Single 3.3V power supply for TIA
  • Differential output
  • Operating temperature from -5°C to +70°C (can be extended to -40°C to +85°C)
