ZR431F01TA

Overview

The ZR431F01TA 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 ±1% initial accuracy tolerance and operates within a temperature range of -40°C to +125°C. It supports a cathode current sink capability from 50µA to 100mA with a maximum temperature coefficient of 72ppm/°C. Packaged in the SOT-23 surface-mount format, it serves as a high-performance replacement for standard Zener diodes.

Feature Summary

Offers excellent temperature stability across the full operating range
Provides programmable output voltage between 2.5V and 20V
Features low output noise characteristics
Totally lead-free and fully RoHS compliant

Applications

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

Procurement Notes

Verify the specific ordering suffix TA indicates the 7-inch tape and reel packaging configuration. Confirm that the F package code corresponds to the SOT-23 form factor required for your PCB layout. Ensure the component meets the RoHS 3 directive standards if applicable to your region. Check for any automotive qualification requirements such as AEC-Q100 if intended for vehicle electronics.

Selection Notes

Select this component when precise voltage referencing is required in space-constrained designs. The SOT-23 package suits automated surface-mount assembly processes. Consider the 1% tolerance for applications demanding tight regulation without complex feedback loops. Evaluate the 100mA current sink capacity against load requirements to ensure adequate thermal dissipation margins.

Part Context

This part belongs to the ZR431 family of adjustable precision shunt regulators. The series includes variants with different tolerances (2%, 1%, 0.5%) and packages (SOT-223). The ZR431F01TA specifically denotes the 1% tolerance version in the SOT-23 package. It is designed to replace discrete Zener diodes where improved performance and stability are necessary.
