概述

Description

DMN2991UFZ-7B is a small-format N-channel enhancement-mode power MOSFET used as a switching transistor in power electronics. It belongs to the DMN2991 family and comes in the UFZ package with a -7B variant code. The device is driven by a logic-level gate and provides low on-resistance and good current capability in a compact package, making it suitable for DC-DC converters, load switches, and motor drivers. Key electricals—drain-source voltage (Vds), continuous drain current (Id), on-resistance (Rds(on)), gate threshold (Vgs(th)), and switching characteristics—are specified in the supplier’s datasheet. The -7B suffix mainly denotes packaging/lot information. For exact figures and thermal limits, consult the official datasheet from the manufacturer. If you share the supplier, I can summarize the precise specs.
