00 — Overview

What the SZNUD3160 does

The NUD3160/SZNUD3160 is a micro-integrated inductive load driver that switches relays, solenoids, and small DC motors without requiring an external free-wheeling diode. It accepts logic level inputs and drives relay coils rated up to 150 mA at 12, 24, or 48 V. The device features a 60 V drain-to-source voltage rating, 20 W peak power dissipation, and 2000 V ESD protection. It meets automotive specifications including load dump and reverse battery conditions. Engineers typically use this component to drive window, latch, door, and antenna relays in both automotive and industrial environments, simplifying circuit design and reducing PCB space.
