Features & Applications
The TFDU4101-TR3 is an infrared transceiver module compliant to the latest IrDA® physical layer standard for fast infrared data communication, supporting IrDA speeds up to 115.2 kbit/s (SIR), and carrier based remote control modes.

This device covers the full IrDA range of more than 1 m using the internal intensity control. With one external current control resistor the current can be adjusted for shorter ranges saving operating current operating in IrDA low power mode.


  • Operates from 2.4 V to 5.5 V within specification over full temperature range from - 30 °C to + 85 °C
  • Split power supply, transmitter and receiver can be operated from two power supplies with relaxed requirements saving costs, US - patent no. 6,157,476
  • Low power consumption (< 0.12 mA supply current in receive mode, no signal)
  • Power shutdown mode (< 4 μA shutdown current in full temperature range, up to 85 °C, < 10 nA at 25 °C)
  • Surface mount package (L x W x H in mm): 9.7 × 4.7 × 4
  • High efficiency emitter
  • Low profile (universal) package capable of surface mount soldering to side and top view orientation
  • Directly Interfaces with various super I/O and controller devices as e. g. TOIM4232
  • Tri-state-receiver output, floating in shut down with a weak pull-up
  • Qualified for lead (Pb)-free and Sn/Pb processing (MSL4)
