ZR431LF02TA

Overview

The ZR431LF02TA is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides excellent temperature stability and an output current handling capability up to 25mA. The output voltage is programmable between 1.24V and 10V using two external divider resistors. This device features a 2.5% initial tolerance, a maximum temperature coefficient of 50ppm/°C, and operates within a temperature range of -40°C to +85°C. It is housed in a surface-mount SOT-23 package.

Feature Summary

Temperature compensated for operation over the full specified temperature range
Programmable output voltage set via external resistor divider
Totally lead-free and fully RoHS compliant with halogen and antimony-free construction

Applications

Shunt Regulator
Series Regulator
Voltage Monitor
Over Voltage/ Under Voltage Protection
Switch Mode Power Supplies

Procurement Notes

Verify the specific ordering suffix TA indicates tape and reel packaging containing 3000 units per reel. Confirm that the LF02 designation strictly corresponds to the 2.5% voltage tolerance variant. Ensure compliance requirements match the manufacturer's definitions for halogen-free and antimony-free green devices before finalizing procurement specifications.

Selection Notes

Select this component when a low-cost, adjustable reference is required for feedback control loops or general regulation. The SOT-23 package suits space-constrained designs. Verify that the 2.5% tolerance meets system accuracy requirements and that the 25mA cathode current limit satisfies load demands without exceeding absolute maximum ratings.

Part Context

This part belongs to the ZR431L family of adjustable precision shunt regulators from Diodes Incorporated. It serves as a direct replacement for standard zener diodes where improved performance characteristics are necessary. The family includes variants with different tolerances, such as the 1% accurate ZR431LF01TA, sharing identical pinouts and functional block diagrams.
