概述

Description

SI4403CDY-T1-GE3 is a single N-channel enhancement-mode MOSFET from Vishay Siliconix. It’s used as a compact power switch in applications like DC-DC converters, load switches, motor/LED drivers, and similar power-management tasks. The GE3 suffix indicates RoHS-compliant, lead-free, tape-and-reel packaging (T1). In use, it behaves as a low-impedance switch when the gate is driven above threshold; the source is usually tied to ground (low-side) or connected to the return node with proper gate drive for high-side use. Key specs to verify in the datasheet are the drain-source voltage rating (Vds), continuous drain current (Id), on-resistance (Rds(on)) at your gate voltage, gate-threshold voltage, total gate charge, and thermal characteristics (RθJA). For exact electrical values and packaging details, consult the Vishay datasheet for SI4403CDY-T1-GE3.
