ZR285R03STZ

Overview

The ZR285R03STZ is a two-terminal shunt voltage reference manufactured by Diodes Incorporated. It provides a nominal output voltage of 2.5 V with an initial accuracy of 1%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 90 PPM/°C. Electrical specifications include a maximum shunt current of 20 mA and a minimum operating current of 20 µA. It is housed in a through-hole E-Line-3 package.

Feature Summary

• Provides stable 2.5 V reference voltage for precision circuits
• Ensures high accuracy with 1% initial tolerance
• Operates reliably across extended industrial temperature ranges

Applications

• Precision analog signal conditioning
• Data acquisition systems requiring stable references
• Battery-powered instrumentation

Procurement Notes

Verify the exact suffix STZ against official Diodes Incorporated documentation to confirm pinout and package compatibility. Confirm availability status as distribution data may indicate limited supply or end-of-life conditions. Ensure the selected component matches the required 1% accuracy and 90 PPM/°C temperature coefficient specifications for the target application.

Selection Notes

Select this component when a low-cost, through-hole shunt reference with 1% accuracy is required. Compare against other ZR285 variants if different accuracies or packages are needed. Verify that the 20 mA maximum current capability meets the load requirements. Consider thermal management within the -40°C to +85°C operating range.
