ZHT431F02TA

Overview

The ZHT431F02TA 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 resistors. The device features a reference voltage of 2.5V with a tolerance of 2%. It operates within a temperature range of -55°C to +125°C and supports a cathode current up to 100mA. Packaged in a surface-mount SOT-23 (Type DN) configuration.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix 'F02' confirms the 2% tolerance grade required for the design. Confirm the 'TA' suffix indicates tape and reel packaging suitable for automated assembly processes. Ensure the application circuit accounts for the specified operating temperature range and maximum power dissipation limits under ambient conditions.

Selection Notes

Select this component when a programmable shunt regulator with extended industrial temperature coverage is required. The 2% tolerance offers a balance between cost and accuracy compared to tighter grades. Verify that the external resistor network can achieve the desired output voltage within the 2.5V to 20V operational window while maintaining stability.

Part Context

This part belongs to the ZHT431 family of adjustable precision Zener shunt regulators. It serves as a high-performance replacement for standard Zener diodes where improved temperature stability and lower dynamic impedance are necessary. The device integrates a bandgap reference core to maintain regulation across wide load and temperature variations.
