SZNUD3112DMT1G

Overview

The SZNUD3112DMT1G is a dual-channel integrated inductive load driver manufactured by onsemi. It operates within a supply voltage range of 4.5 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. Designed for surface-mount installation, it utilizes a SC-74-6 package and supports an operating temperature range from -40°C to +125°C. This component integrates MOSFET switches, ESD protection, and Zener clamping to directly drive inductive loads without external freewheeling diodes.

Feature Summary

• Integrates dual MOSFET switches with built-in ESD protection and Zener clamping for direct inductive load control
• Accepts standard logic-level inputs compatible with microcontrollers and inverters
• Eliminates the need for external freewheeling diodes through internal circuit integration

Applications

• Relay switching circuits
• Solenoid and electromagnetic valve drivers
• Incandescent lamp control systems
• Small DC motor actuation

Procurement Notes

Verify the specific suffix DMT1G against official datasheets to confirm the dual-channel SC-74-6 package variant. Ensure compatibility with system voltage limits and thermal requirements before procurement. Cross-reference manufacturer part numbers to distinguish between single and dual driver versions within the NUD3112 series.

Selection Notes

Select this component when dual independent control of inductive loads is required in a compact footprint. The integrated protection features simplify schematic design by removing external snubber or flyback diode requirements. Verify that the input logic levels match the driving controller's output specifications for reliable operation across the full temperature range.
