Overview
The onsemi SZNUD3124LT1G is a single-channel inverting gate driver designed for inductive loads, housed in an SOT-23-3 surface-mount package. It operates within a supply voltage range of 12 V to 28 V and delivers a peak output current of 150 mA. The device features a rise time of 708 ns and a fall time of 2.086 µs. It is qualified under AEC-Q100 standards and supports an operating temperature range from -40 °C to +125 °C.
Feature Summary
- AEC-Q100 automotive qualification for enhanced reliability
- Inverting logic configuration for simplified control integration
- High surge current capability suitable for inductive load driving
Applications
- Automotive relay actuation circuits
- Solenoid valve control systems
- Inductive load switching applications
Procurement Notes
Verify the complete part number including the 'SZ' prefix and 'LT1G' suffix to ensure correct variant identification. Confirm AEC-Q100 compliance requirements against specific project specifications. Validate that the SOT-23-3 package dimensions align with the target PCB footprint. Ensure the 12 V to 28 V supply range matches the system power architecture.
Selection Notes
Select this component when an inverting drive signal is required for high-current inductive loads in automotive environments. The SOT-23-3 package offers space efficiency for compact designs. Consider the 150 mA output capability for driving standard automotive relays or solenoids directly without external transistors. Verify thermal performance within the specified -40 °C to +125 °C range for harsh operating conditions.
Part Context
This device belongs to the NUD3124 series of gate drivers from onsemi. The series focuses on robust solutions for automotive inductive loads. The 'SZ' prefix typically denotes specific regional or manufacturing variants within the broader product line. The LT1G suffix indicates the tape and reel packaging format and RoHS compliance status.
Replacement Considerations
Check for direct cross-reference availability within the NUD3124 family. Verify pinout compatibility if substituting with other SOT-23-3 gate drivers. Ensure equivalent AEC-Q100 qualification levels are maintained for automotive safety-critical applications.
