Overview
The NCP431BVSNT1G is a programmable precision shunt reference from the NCP431 series, manufactured by onsemi. It operates as a low temperature coefficient Zener diode, adjustable from Vref to 36 V using two external resistors. The device features a typical voltage reference tolerance of ±0.5% at 25°C and an equivalent full-range temperature coefficient of 50 ppm/°C. It supports a cathode current range of 40 µA to 100 mA with a typical dynamic impedance of 0.22 Ω. Qualified under AEC-Q100 standards, it functions within an ambient temperature range of -40°C to +125°C.
Feature Summary
- Programmable output voltage capability extending up to 36 V via external resistor networks
- High precision performance with ±0.5% initial accuracy and low temperature drift
- Automotive qualification ensuring reliability through AEC-Q100 certification and PPAP capability
- Low minimum operating current enabling efficient secondary regulation in switch-mode power supplies
Applications
- Voltage adapters and precision voltage references
- Switching power supply secondary side regulation
- Battery chargers and instrumentation circuits
Procurement Notes
Verify that the specific ordering suffix matches the required temperature grade and package configuration for your design. Confirm AEC-Q100 qualification status if automotive compliance is mandatory. Ensure the SOT-23-3 footprint aligns with your PCB layout constraints. Cross-reference the manufacturer part number against official distributor catalogs to confirm authenticity and revision level before finalizing procurement orders.
Selection Notes
Select this component when high precision and wide temperature stability are required for shunt regulation applications. The NCP431B variant offers tighter tolerance compared to standard versions, making it suitable for sensitive analog circuits. Consider the low minimum operating current for battery-powered or low-power standby modes. Verify that the 36 V maximum cathode-to-anode voltage exceeds your circuit's peak operating requirements.
Part Context
This device belongs to the NCP431/SC431 family of programmable precision references. It serves as a direct replacement for traditional Zener diodes in many applications, offering superior stability and adjustability. The SC prefix indicates automotive-grade manufacturing with unique site and control change requirements, distinguishing it from commercial variants like the NCP431BV.
