NCP431BVPSNT1G

Overview

The NCP431BVPSNT1G is a three-terminal programmable shunt regulator diode manufactured by onsemi. It serves as a direct upgrade to the industry standard TL431A. The device features an adjustable output voltage range up to 36 V with an initial accuracy of ±0.5% and a temperature coefficient of 50 ppm/°C. It operates within a cathode current range from 40 µA to 100 mA, supporting a maximum power dissipation of 1.5 W. The component is housed in a surface-mount SOT-23-3 package and is rated for an extended operating temperature range from -40°C to +125°C.

Feature Summary

Provides precise programmable shunt regulation with high initial accuracy
Supports wide operating temperature range suitable for demanding environments
Functions as a direct replacement for legacy TL431A devices

Applications

Precision voltage reference circuits
Programmable power supply feedback loops
Battery management system monitoring

Procurement Notes

Verify the specific suffix 'BV' against official datasheets to confirm the ±0.5% accuracy grade and industrial temperature rating. Ensure the ordering part number matches the exact package and tape/reel specifications required for your assembly process. Cross-reference with the manufacturer's latest documentation to confirm RoHS compliance and material declarations before finalizing procurement.

Selection Notes

Select this component when higher accuracy than standard TL431 variants is required without increasing cost significantly. The SOT-23-3 package offers space efficiency for compact designs. Consider the 100 mA cathode current limit for load requirements. The extended temperature range makes it suitable for automotive or industrial applications where standard commercial grades may fail.

Part Context

This part belongs to the NCP431 series, which includes variants like NCP431BVSNT1G and SC431AVSNT1G. These devices are designed to replace older generation shunt regulators while offering improved performance characteristics. The series is widely used in power management integrated circuits (PMIC) for stable voltage referencing in various electronic systems.
