ZR285R01STOB

Overview

The ZR285R01STOB is a shunt voltage reference manufactured by Diodes Incorporated, designed for through-hole mounting in an E-Line-3 package. It provides a fixed 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.

Feature Summary

• Provides stable 2.5 V reference voltage via shunt regulation architecture
• Ensures high precision with 1% initial accuracy tolerance
• Supports low current operation down to 20 µa minimum shunt current

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Battery-powered instrumentation requiring low knee voltage performance

Procurement Notes

Verify component authenticity against manufacturer documentation due to potential supply chain variations. Confirm RoHS compliance status as indicated in official datasheets, noting that specific suffixes may affect regulatory attributes. Validate package integrity upon receipt to ensure the E-Line-3 form factor matches design requirements before assembly integration.

Selection Notes

Select this component when a low-cost, through-hole shunt reference is required for 2.5 V applications. The 1% accuracy suits general-purpose precision circuits. Ensure the circuit design accommodates the 20 µA minimum current requirement to maintain regulation stability across the specified -40°C to +85°C operating temperature range without exceeding the 20 mA maximum shunt current limit.

Part Context

This part belongs to the ZR series of voltage references from Diodes Incorporated, specifically utilizing the R01 suffix to denote the 2.5 V output variant. The STOB suffix indicates the specific E-Line-3 through-hole packaging configuration. This series is categorized under PMIC voltage references, distinct from the ZRB or ZDX product lines found in related catalogs.
