STS1DNC45 Description

Short technical summary and product information.

The STMicroelectronics STS1DNC45 is a dual N-channel MOSFET belonging to the SuperMESH™ series. It is engineered for medium-power switching applications, offering a high voltage tolerance of up to 450V and a continuous drain current of 400mA at 25°C. This MOSFET supports a maximum power dissipation of 1.6W and operates at junction temperatures up to 150°C.

 

Key electrical characteristics include a maximum on-resistance of 4.5 Ohms at 500mA and 10V, a gate threshold voltage of 3.7V at 250µA, a maximum gate charge of 10nC at 10V, and a maximum input capacitance of 160pF at 25V. The device is housed in a compact 8-SOIC package suitable for surface mounting.

 

Its dual N-channel structure integrated into a single package allows for flexible low-power switching and load control. The design maximizes thermal efficiency and minimizes parasitic elements, contributing to reliable high-speed switching and overall system efficiency. The STS1DNC45 is suitable for compact, power-sensitive designs requiring robust performance in demanding applications.
