TL431 Adjustable Precision Zener Diode - SOT-23 SMD Package
The TL431 is a three-terminal adjustable precision shunt regulator, often used as a programmable Zener diode, provided here in a compact SOT-23 SMD package. It offers a stable voltage reference with an adjustable output voltage range from 2.5V to 36V. Unlike fixed Zener diodes, the TL431 allows precise setting of the output voltage through external resistors, making it highly versatile for use in power supply regulation, voltage monitoring, switching regulators, and other precision circuits.
Features of TL431 SOT-23 Zener Diode:
- Adjustable precision Zener diode (programmable shunt regulator)
- Output voltage range: 2.5V to 36V (adjustable with resistors)
- Compact SOT-23 SMD package for space-saving PCB layouts
- High stability and low dynamic impedance
- Programmable voltage reference with ±1% accuracy (depending on grade)
- Suitable for power supplies, SMPS, reference circuits, and monitoring applications
- RoHS compliant and suitable for automated SMD assembly
