Overview
The ZR431GTC is a three-terminal adjustable shunt voltage reference manufactured by Diodes Incorporated. It provides an output voltage range from 2.5V to 20V with an initial accuracy of ±2%. The device features a temperature coefficient of 50 PPM/°C and supports a maximum cathode current of 100mA. It operates within a supply voltage range up to 20V and functions across a temperature range of -40°C to +85°C. The component is housed in a surface-mount SOT-223 package.
Feature Summary
- Provides stable, adjustable shunt regulation with high temperature stability
- Supports high output current handling capability up to 100mA
- Offers precise voltage referencing with ±2% initial accuracy
Applications
- Precision voltage references in industrial control systems
- Voltage regulation for portable battery-powered devices
- Power management circuits requiring stable reference voltages
Procurement Notes
Verify the specific suffix GTC confirms the SOT-223 surface-mount package and 20V rating. Confirm RoHS compliance status as availability varies. Check for obsolescence notices or lifecycle changes directly from Diodes Incorporated documentation before finalizing procurement plans.
Selection Notes
Select this component when a surface-mount solution is required for adjustable shunt regulation. Ensure the application demands a maximum operating voltage of 20V and can accommodate the 100mA current limit. Verify that the ±2% accuracy and 50 PPM/°C drift meet the system's precision requirements compared to lower-drift alternatives.
Part Context
This part belongs to the ZR431 series of programmable shunt regulators. It serves as a cost-effective alternative to discrete zener diodes, offering superior temperature stability and current handling. The series is widely used in power supplies and monitoring circuits where reliable voltage referencing is critical.
Replacement Considerations
Consider the ZR431LC02L for through-hole TO-92 applications requiring similar functionality. Evaluate the AS431AZTR-G1 for higher precision needs with ±0.5% accuracy and extended temperature ranges. Always verify pinout compatibility and electrical specifications against the original design requirements.
