SZNUD3124DMT1G Description

Short technical summary and product information.

The SZNUD3124DMT1G from ON Semiconductor is a micro-integrated inductive load driver. This component is designed to switch inductive loads such as relays, solenoids, and small DC motors without requiring an external free-wheeling diode, thanks to its internal Zener protection.

 

It accepts logic-level inputs, allowing it to be driven by microcontrollers, logic gates, and inverters. The device is capable of driving relay coils rated up to 150 mA at 12 Volts. Key electrical specifications include a continuous drain current of 150mA and a maximum Rds On of 800mOhm.

 

The SZNUD3124DMT1G is housed in a SC-74 package, suitable for surface mount applications. It operates within a temperature range of -40°C to 125°C (TA). The 'SZ' prefix indicates suitability for automotive applications, AEC-Q101 qualification, and PPAP capability.

 

This load driver simplifies circuit design and reduces PCB space by replacing 3 or 4 discrete components. It meets load dump and other automotive specifications, making it a reliable choice for automotive and industrial environments, including driving window, latch, door, and antenna relays.
