KA431SMFTF

Overview

The KA431SMFTF is an adjustable shunt voltage reference from onsemi, housed in a SOT-23F-3 package. It operates within a reference voltage range of 2.5 V to 36 V and supports a minimum shunt current of 1 mA. The device is rated for an operating temperature range of -25 °C to 85 °C. Initial accuracy specifications are documented at ±1% or ±2%, with a temperature coefficient of -0.02%/°C.

Feature Summary

Adjustable shunt regulation architecture
Integrated precision bandgap reference
Compact surface-mount packaging

Applications

Voltage regulation circuits
Power supply feedback loops
Battery monitoring systems

Procurement Notes

This component is officially obsolete and no longer manufactured by onsemi. Procurement must rely on secondary market distributors or verified substitute components. Verify lot dates and authenticity carefully when sourcing from non-OEM channels due to end-of-life status.

Selection Notes

Designers should evaluate the recommended replacement NCP431AISNT1G for continued production availability. Ensure the substitute matches the required voltage range, accuracy class, and thermal performance specifications for the target application environment.

Part Context

Part of the KA431S series of programmable shunt regulators. Manufactured by onsemi (formerly Fairchild Semiconductor). Designed for general-purpose voltage reference applications requiring stable output over varying load conditions.
