ZR431F005TA

Overview

The ZR431F005TA is a three-terminal adjustable precision Zener shunt regulator manufactured by Diodes Incorporated. It provides an output voltage range from 2.5V to 20V, set via external divider resistors. The device features a ±0.5% initial tolerance and operates with a cathode current capability of 50µA to 100mA. It utilizes a SOT-23 surface-mount package and maintains temperature compensation across the full operating range.

Feature Summary

Temperature compensated for operation over the full temperature range
Low output noise characteristics
Totally lead-free and fully RoHS compliant
Halogen and antimony free green device

Applications

Shunt regulators
Series regulators
Voltage monitors
Overvoltage/undervoltage protections
Switch mode power supplies

Procurement Notes

Verify the specific ordering suffix TA indicates tape and reel packaging configuration. Confirm the F package code corresponds to the SOT-23 form factor required for your PCB layout. Ensure the 005 tolerance designation matches the circuit accuracy requirements before finalizing procurement orders.

Selection Notes

Select this component when high precision is required due to its 0.5% tolerance rating. The SOT-23 package suits space-constrained designs. Verify that the maximum cathode voltage of 20V aligns with system supply rails. Consider the low knee current requirement if designing for minimal standby power consumption applications.

Part Context

This part belongs to the ZR431 family of adjustable precision shunt regulators. It serves as a direct replacement for standard Zener diodes where improved performance and stability are necessary. The series offers various tolerance options and package types to accommodate different manufacturing and design constraints.

Replacement Considerations

ZR431F005-7 is an End-of-Life (EOL) variant within the same product line. Designers should transition to the ZR431F005TA or equivalent active parts to ensure long-term supply availability and consistent manufacturing quality standards.
