ZR431F005-7

Overview

The ZR431F005-7 is a three-terminal adjustable precision zener shunt regulator manufactured by Diodes Incorporated. It provides an output voltage range from 2.5 to 20 volts, set via external divider resistors. The device features a 0.5% initial accuracy tolerance and a maximum temperature coefficient of 55 ppm/°C. It operates within a cathode current range of 50 µA to 100 mA and supports a maximum cathode voltage of 20 V. The component is housed in a surface-mount SOT23 package and functions as a temperature-compensated reference source.

Feature Summary

Temperature compensated for operation over the full temperature range
Programmable output voltage using two external divider resistors
Low output noise characteristics

Applications

Shunt regulator
Series regulator
Voltage monitor
Over voltage/ under voltage protection
Switch mode power supplies

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the 3000-unit tape and reel packaging format. Confirm that the 'F' code indicates the SOT23 package variant with 0.5% tolerance. Ensure compliance requirements match the manufacturer's Green Molding Compound specifications and RoHS directives before finalizing procurement orders.

Selection Notes

Select this component when precise voltage referencing is required in space-constrained designs utilizing surface-mount technology. The SOT23 package offers a compact footprint suitable for dense PCB layouts. The 0.5% tolerance ensures high accuracy for applications demanding strict voltage regulation limits without requiring additional calibration steps during assembly.

Part Context

This part belongs to the ZR431 family of adjustable precision zener shunt regulators produced by Diodes Incorporated. The family includes variants with different tolerances (2%, 1%, 0.5%) and packages (SOT223, SOT23). The ZR431 series serves as a direct replacement for standard zener diodes where improved stability and programmability are necessary.
