SZNUD3105DMT1G

Overview

The onsemi SZNUD3105DMT1G is a dual-channel low-side power switch designed for inductive load control. It operates with a supply voltage range of 4V to 28V and delivers a continuous output current of 350mA per channel. The device features an integrated bootstrap diode, enabling efficient high-side driving capabilities when configured appropriately. Key electrical parameters include a maximum on-resistance of 900mΩ and a peak pulse current capability of 1A. It is housed in a compact SC-74 (SOT-457) surface-mount package, suitable for space-constrained automotive and industrial applications requiring reliable switching performance.

Feature Summary

Dual-channel configuration for independent or synchronized load control
Integrated bootstrap diode simplifies circuit design for inductive loads
Low on-resistance minimizes power dissipation during conduction
Robust protection against thermal overload and short-circuit conditions

Applications

Automotive relay and solenoid driver circuits
Inductive load switching in industrial control systems
Low-power motor drive interfaces
General-purpose power distribution switches

Procurement Notes

Verify the exact ordering suffix matches the required tape-and-reel quantity and packaging specifications. Confirm that the component meets AEC-Q100 qualification requirements if deployed in automotive environments. Ensure compatibility with existing PCB footprint dimensions and thermal management strategies before finalizing procurement orders.

Selection Notes

Select this component when dual-channel switching with integrated bootstrap functionality is required. Consider the 900mΩ on-resistance limit for efficiency calculations. Evaluate the SC-74 package size against available board space. Verify input logic voltage levels align with the system's microcontroller or driver outputs.

Part Context

This part belongs to the NUD3105 series of dual low-side drivers from onsemi. It complements single-channel variants by offering two independent outputs in a minimal footprint. The series targets applications needing controlled switching of small inductive loads without external discrete components for bootstrap operation.
