NUD3112DMT1

Overview

The NUD3112DMT1G is an integrated load driver designed for switching inductive loads such as relays and solenoids. It combines a MOSFET switch with ESD protection and Zener clamping in a single SOT-89 package. The device accepts logic-level inputs, allowing direct interfacing with microcontrollers or logic gates without external components.

Feature Summary

• Integrates MOSFET switch, ESD protection, and Zener clamping
• Accepts logic-level input signals for easy driving
• Eliminates the need for external freewheeling diodes

Applications

• Switching of relay coils
• Control of solenoid actuators
• Driving small DC motors

Procurement Notes

Verify the part number suffix carefully; the provided model lacks the 'G' RoHS compliance suffix typically found in official onsemi documentation (NUD3112DMT1G). Ensure the datasheet revision matches the specific manufacturing batch requirements for your design integration.

Selection Notes

Select this component when space constraints require an integrated solution for inductive load control. It is suitable for applications requiring direct logic interface and built-in transient suppression, simplifying the bill of materials by removing discrete protection components.

Part Context

This device belongs to the NUD3112 series of integrated load drivers from onsemi. It is part of a family of compact solutions designed to replace discrete MOSFET and diode configurations in low-power inductive switching applications, offering a simplified design approach.
