ZR431C01L

Overview

The ZR431C01L is a three-terminal adjustable precision shunt voltage reference manufactured by Diodes Incorporated. It operates within an output voltage range of 2.5V to 20V and provides an initial accuracy of 1%. The device features a temperature coefficient of 50 PPM/°C and supports a maximum shunt current of 25 mA with a minimum operating current of 100 µA. It is housed in a TO-92-3 through-hole package, rated for operation between -40°C and +85°C, and has a maximum series input voltage of 10 V.

Feature Summary

Provides precise programmable output voltage via external resistors
Offers excellent thermal stability across the industrial temperature range
Features sharp turn-on characteristics suitable for regulation applications

Applications

Adjustable power supply circuits
Battery chargers
Motherboard voltage regulation

Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm that the TO-92-3 package matches the target PCB footprint. Ensure the 1% tolerance meets system requirements. Check for RoHS compliance status if required by local regulations. Validate that the 10 V maximum input voltage is sufficient for the specific circuit design.

Selection Notes

Select this component when a low-cost, through-hole adjustable reference is needed. The 1% accuracy suits general-purpose regulation where high precision is not critical. Consider the 25 mA current limit for load requirements. The TO-92 package facilitates manual assembly or prototyping. Verify compatibility with existing thermal management strategies for the specified temperature range.

Part Context

This part belongs to the ZR431 family of adjustable shunt regulators from Diodes Incorporated. It serves as a cost-effective alternative to traditional Zener diodes in linear regulation contexts. The family offers various tolerance grades and packaging options to support diverse electronic design needs.
