TL431K-AF5-R Description

Short technical summary and product information.

The TL431K-AF5-R is a programmable shunt voltage reference manufactured by UTC. It is designed to provide a precise adjustable output voltage that can be set from 2.5V to 36V using two external resistors. The device features a low dynamic output impedance of 0.2 Ohms, ensuring stable operation. It can sink current from 1.0mA to 100mA, making it suitable for a variety of applications such as voltage regulation, current limiting, and precision reference sources.

 

The TL431K-AF5-R offers a typical temperature coefficient of 50 ppm/°C over the full operating temperature range of -40°C to +85°C. The device can handle a maximum cathode voltage of 37V and continuous cathode current from -100mA to +150mA. The reference input current range is -0.05mA to +10mA. Power dissipation depends on the package: for the SOT-25 package, it is 300mW.

 

This component is supplied in a surface-mount SOT-25 package, suitable for automated assembly, and is available in tape and reel packaging with a standard quantity of 3000 units. It is compliant with RoHS and REACH, and is lead-free and halogen-free. The junction temperature limit is 150°C, and the storage temperature range is -65°C to +150°C.
