Overview
The HA17431FPAJ-E is a temperature-compensated variable shunt voltage reference IC manufactured by Renesas Electronics Corporation. It is housed in an 8-PSOP package with dimensions of 4.40 x 4.85 mm and a 1.27 mm pitch. The device provides a fixed output voltage of 2.495V with a tolerance of ±1%. It functions as a two-terminal voltage reference suitable for precision applications requiring stable regulation.
Feature Summary
- Temperature-compensated design ensures stable performance across operating ranges
- Fixed output voltage configuration for simplified circuit integration
- Compact plastic surface-mount packaging for space-constrained designs
Applications
- Precision voltage reference circuits
- Shunt regulator applications
- Power supply monitoring systems
Procurement Notes
Verify the exact part number suffix to confirm package type and tolerance specifications. Ensure compatibility with existing PCB footprints, specifically the 8-PSOP outline. Confirm that the fixed 2.495V output meets system requirements before procurement. Check for RoHS compliance status if required by project standards.
Selection Notes
Select this component when a low-cost, temperature-compensated shunt reference is needed. The fixed 2.495V output suits applications where this specific reference level is required without external adjustment. Consider the ±1% tolerance for accuracy needs. The PSOP package is suitable for automated assembly processes.
Part Context
This device belongs to the HA17431 series of temperature-compensated variable shunt regulators. The series is designed for general-purpose voltage reference applications. The FPAJ-E designation indicates the specific package style and manufacturing variant within the broader product line.
Replacement Considerations
Check for direct pin-compatible substitutes from the same manufacturer or other vendors offering similar shunt references with comparable voltage and tolerance specifications. Verify thermal characteristics and package dimensions for mechanical fit.
