NUD3105LT1

Overview

The NUD3105LT1 is an integrated power driver designed for low-side switching of inductive loads such as relays and solenoids. It features a single N-channel output capable of delivering up to 300mA of continuous current with a typical on-resistance of 900 milliohms. The device operates within a supply voltage range of up to 6V and supports a wide ambient operating temperature from -40°C to +85°C. Packaged in the compact SC-74 (SOT-457) surface-mount format, it integrates necessary control logic for direct interface with standard digital signals.

Feature Summary

Integrated low-side switching architecture for simplified circuit design
Capable of driving inductive loads like relays and solenoids
Direct interface compatibility with standard digital control signals

Applications

Automotive relay control circuits
Solenoid actuation systems
Industrial load switching applications

Procurement Notes

Verify the specific suffix and manufacturer marking against official datasheets to confirm authenticity. Ensure the component matches the required package type and electrical ratings for the target application. Cross-reference ordering information with authorized distributors to avoid counterfeit parts.

Selection Notes

Select this component when a compact solution is needed for driving small inductive loads directly from a microcontroller or logic gate. Consider the maximum current rating and thermal performance relative to the PCB layout. Verify that the input voltage levels are compatible with the controlling logic family.

Part Context

This part belongs to the family of integrated power drivers manufactured by onsemi. It serves as a bridge between low-power control logic and higher-power inductive loads. Similar devices in the lineup may offer different current capacities or packaging options, but share the core functionality of integrated low-side switching.
