Overview
The ZHT2431F02TA is an adjustable shunt voltage reference IC manufactured by Diodes Incorporated. It provides a stable reference voltage with an output range starting at 1.24V. The device supports an input voltage up to 15V and maintains accuracy within ±2.5%. It can handle a maximum output current of 25mA. The component is housed in a compact SOT-23-3 surface-mount package, designed for efficient thermal performance and space-constrained circuit layouts.
Feature Summary
- Adjustable shunt regulation architecture for flexible voltage setting
- High temperature stability ensuring consistent performance across operating ranges
- Compact SOT-23-3 surface-mount packaging for board space efficiency
Applications
- Precision voltage reference sources in measurement circuits
- Feedback loop stabilization in switching power supplies
- Comparator reference voltage generation in control systems
Procurement Notes
Verify the specific suffix 'F02' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and exact tolerance grades. Ensure the sourcing channel provides traceability documentation matching Diodes Incorporated manufacturing records. Cross-reference the part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components.
Selection Notes
Select this component when an adjustable shunt regulator is required with moderate current capability. The 25mA limit suits low-power applications rather than high-current loads. Consider the ±2.5% tolerance if higher precision is needed, as other variants offer tighter specifications. The SOT-23-3 package dictates footprint constraints during PCB layout design.
Part Context
This part belongs to the ZHT series of shunt regulators from Diodes Incorporated. It shares architectural similarities with the ZHT431 family but differs in voltage range and current handling capabilities. The ZHT2431 variant specifically targets applications requiring lower minimum reference voltages compared to fixed 2.5V or 3.3V alternatives.
Replacement Considerations
The ZHT431F02TA serves as a functional substitute within the same product line, offering similar packaging and regulatory principles. Verify that the application circuit accommodates the ZHT431's fixed 2.5V output if replacing the adjustable ZHT2431F02TA.
