Vishay SI2319DS P-Channel Power MOSFET 40V 3A SMD
Vishay -40V P-Channel Power MOSFET, 3A, 0.082 ohm Rds(on), in TO-236 SMD package. Halogen-free for power management.
The Vishay SI2319DS-T1-E3 is a high-performance, -40V P-channel TrenchFET™ Power MOSFET in a compact surface-mount package. Designed for efficient power management, this MOSFET offers a low on-state resistance for minimal power loss and heat generation. Its robust construction ensures reliable operation in demanding electronic circuits.
Part of the LITTLE FOOT® series, this device utilises modified integrated circuit packaging to deliver the necessary heat dissipation for power applications. This makes it an excellent choice for space-constrained designs where thermal performance is critical. The component is halogen-free, complying with the IEC 61249-2-21 environmental standard.
With its combination of a 40V drain-source voltage rating and a 3A continuous drain current, it provides a solid foundation for switching and control tasks. The low gate threshold voltage facilitates easy interfacing with logic-level control signals from microcontrollers or other digital circuits.
