SZNUD3124DMT1G

Overview

The onsemi SZNUD3124DMT1G is a dual-channel low-side N-channel power switch and load driver designed for inductive loads. It operates within a supply voltage range of 12 V to 28 V and delivers an output current of 150 mA per channel. The device features an inverting logic configuration with typical rise and fall times of 708 ns and 2.086 µs, respectively. Packaged in a compact SC-74 (SOT-457) surface-mount format, it supports automotive applications through AEC-Q100 qualification and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent control for two separate inductive loads
• Automotive-grade reliability certified under the AEC-Q100 standard
• Integrated low-side N-channel topology for direct switching of solenoids and relays
• Robust thermal performance supporting operation up to 125°C ambient temperature

Applications

• Automotive relay drivers
• Inductive load switching
• Solenoid control circuits
• Low-voltage DC motor interfaces

Procurement Notes

Verify the specific suffix 'DMT1G' to confirm the dual-channel variant and SC-74 package type. Ensure compatibility with the required 12V–28V operating range and 150mA current rating. Confirm AEC-Q100 certification status if automotive compliance is mandatory. Check RoHS and REACH declarations against current regulatory requirements before finalizing procurement specifications.

Selection Notes

Select this component when dual-channel isolation is required within a minimal footprint. The SC-74 package offers space efficiency compared to larger alternatives. Consider the 150mA continuous drive capability for moderate inductive loads. Verify that the inverting input logic aligns with the system's control interface. Evaluate the thermal dissipation characteristics relative to the PCB layout constraints.

Part Context

This part belongs to the NUD3124 series of single and dual-channel MOSFET drivers. It serves as a specialized solution for managing multiple low-power inductive loads in constrained spaces. The series emphasizes automotive durability and simplified integration for systems requiring reliable switching without complex external gate drive circuitry.

Replacement Considerations

Check for NUD3124LT1G if a single-channel SOT-23-3 package is acceptable instead of the dual-channel SC-74 form factor. Verify pinout compatibility and electrical parameters before substituting any alternative dual-channel drivers.
