Overview
The ZR431F01TC is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides excellent temperature stability and output current handling capability up to 100mA. The output voltage is programmable between 2.5V and 20V using two external divider resistors. This device serves as a high-performance replacement for standard Zener diodes in applications requiring improved regulation accuracy.
Feature Summary
- Offers precise reference voltage with ±1% tolerance
- Features low dynamic output impedance for stable regulation
- Includes temperature compensation across the full operating range
- Supports surface-mount SOT23 package configuration
Applications
- Shunt regulators
- Series regulators
- Voltage monitors
- Overvoltage/undervoltage protections
- Switch mode power supplies
Procurement Notes
Verify the specific ordering suffix 'TC' against official manufacturer documentation, as standard listings typically utilize 'TA'. Confirm that the component matches the required ±1% tolerance and SOT23 package specifications. Ensure compatibility with RoHS 3 compliance standards before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring a programmable voltage reference between 2.5V and 20V. It is suitable for replacing discrete Zener diodes where tighter tolerance and lower temperature drift are necessary. Ensure the design accommodates the minimum cathode current requirement of 50µA for proper regulation.
Part Context
This part belongs to the ZR431 family of adjustable precision Zener shunt regulators from Diodes Incorporated. The family includes variants with different tolerances (±0.5%, ±1%, ±2%) and packages (SOT23, SOT223). The ZR431 series is designed to provide superior performance over standard Zener diodes in feedback loops and reference applications.
Replacement Considerations
Compatible substitutes include the TL431BCDBZR from Texas Instruments. Verify pinout compatibility and electrical characteristics such as reference voltage and maximum cathode current before implementing any cross-manufacturer replacements.
