KA431ZTF

Overview

The KA431ZTF is a programmable shunt voltage reference manufactured by onsemi. It operates in a TO-92-3 Kinked Lead through-hole package. The device provides an adjustable output voltage range up to 36 V. Key electrical specifications include an initial accuracy of 2%, a temperature coefficient of 50 PPM/C, and a maximum series input voltage of 37 V. It supports a maximum shunt current of 100 mA and a minimum operating current of 1 mA. The component functions within a temperature range of -25 C to +85 C.

Feature Summary

Programmable output voltage capability via external resistor divider network
Low dynamic output impedance for stable regulation performance
Fast turn-on response characteristic for active output circuitry

Applications

Precision voltage references in power supply circuits
Adjustable shunt regulator implementations
Voltage monitoring and control systems

Procurement Notes

Verify the specific suffix ZTF against the manufacturer's official datasheet to confirm pinout and packaging details. Confirm RoHS compliance status as indicated in the product documentation. Check for any temporary certification suspensions or manufacturing changes that may affect procurement. Ensure the source document explicitly lists KA431ZTF as the active part number before ordering.

Selection Notes

Select this component when a through-hole programmable shunt regulator is required with 2% initial accuracy. Consider the 50 PPM/C temperature coefficient for thermal stability requirements. Verify that the 37 V maximum input voltage and 100 mA current limits suit the target application design constraints.

Part Context

The KA431ZTF belongs to the KA431 family of three-terminal adjustable precision shunt regulators produced by onsemi. This family utilizes bipolar technology to provide reliable voltage reference functionality. The device serves as a core component for setting precise voltage levels in analog and mixed-signal electronic designs.
