Overview
The ZR431CSTOB is a three-terminal adjustable shunt voltage reference IC manufactured by Diodes Incorporated. It provides excellent temperature stability and handles output currents up to 100 mA. The device operates within a supply voltage range of 2.5 V to 20 V with an initial accuracy of ±2%. It is housed in a TO-92-3 package, making it suitable for compact designs requiring precise voltage regulation.
Feature Summary
- Three-terminal adjustable shunt regulator architecture
- High output current handling capability up to 100 mA
- Excellent temperature stability across operating ranges
- Compact TO-92-3 surface mount compatible package
Applications
- Precision voltage references in power supplies
- Programmable linear regulators
- Battery chargers requiring stable reference voltages
- Over-voltage protection circuits
Procurement Notes
Verify the specific suffix 'STOB' corresponds to the TO-92-3 package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the supplier provides genuine Diodes Incorporated parts to guarantee the specified ±2% accuracy and thermal performance characteristics are met.
Selection Notes
Select this component when a low-cost, adjustable shunt reference is needed for applications requiring up to 100 mA load current. The TO-92-3 package is ideal for through-hole or space-constrained PCB layouts where standard SOT packages may not fit. Consider the 2.5 V minimum operating voltage when designing input supply rails.
Part Context
This part belongs to the ZR431 series of adjustable shunt regulators from Diodes Incorporated. It serves as a cost-effective alternative to fixed voltage references in analog and mixed-signal circuits. The series is widely used in consumer electronics and industrial control systems where reliable voltage regulation is critical.
Replacement Considerations
Check for direct pin-compatible substitutes such as other ZR431 variants with different suffixes indicating package changes. Verify that any replacement maintains the 100 mA current rating and ±2% accuracy specification. Ensure the thermal resistance and operating temperature range match the original design requirements.
