Overview
The ZR285R02STOB is a shunt voltage reference integrated circuit manufactured by Diodes Incorporated. It provides a fixed output voltage of 2.5 V with an initial accuracy tolerance of ±2%. 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. The component utilizes a through-hole E-Line-3 package, classified under PMIC voltage references.
Feature Summary
- Provides stable precision voltage reference for measurement circuits
- Designed for low knee voltage applications
- Through-hole mounting capability
Applications
- Precision measurement systems
- Control circuitry requiring stable reference voltages
- Analog signal processing interfaces
Procurement Notes
Verify component authenticity against official Diodes Incorporated documentation due to discontinued status. Confirm package integrity and pin compatibility during replacement sourcing. Ensure environmental compliance records match project requirements. Cross-reference datasheet revisions to validate parameter consistency before integration into production designs.
Selection Notes
Select this component when a 2.5 V shunt reference with ±2% tolerance is required. Consider the 90 PPM/°C temperature coefficient for thermal stability needs. Evaluate the 20 mA maximum current limit against load requirements. Verify through-hole E-Line-3 package constraints against PCB layout specifications.
Part Context
Part of the ZR285R series designed for low knee voltage performance. Manufactured by Diodes Incorporated as a precision shunt reference. Classified under PMIC power management integrated circuits. Provides fixed voltage output for analog circuit stabilization.
Replacement Considerations
ZR285R01STOA offers similar 2.5 V output but with 1% accuracy and E-Line-2 package. ZR285Y01STZ provides 2.5 V output with 1% accuracy in E-Line-2 package. Verify package dimensions and electrical tolerances when substituting.
