The SCH2819-P-TL-H is a composite switching device manufactured by onsemi, integrating an N-channel silicon MOSFET and a Schottky barrier diode within a single package. This configuration facilitates high-density mounting for general-purpose applications. The component features low ON-resistance and ultrahigh-speed switching capabilities, supporting 2.5V drive levels. The integrated Schottky diode provides a short reverse recovery time and low forward voltage. Designed for surface-mount installation, the device combines power switching and rectification functions to optimize board space and performance in compact electronic designs.
Verify the specific suffix -P-TL-H against official onsemi documentation to confirm tape-and-reel packaging and lead-free status. Ensure the part number matches the exact composite device description rather than generic MOSFET listings. Cross-reference with authorized distributors to confirm current availability and authenticity of the onsemi branded component.
Select this component when space constraints require combining a switch and a freewheeling diode into a single footprint. The 2.5V drive capability makes it suitable for logic-level control interfaces. Evaluate the thermal requirements based on the combined power dissipation of both the MOSFET and the Schottky diode during operation.
This part belongs to onsemi's SCH series of composite devices, which combine discrete semiconductor functions to reduce assembly complexity. It serves as a specialized solution for applications needing both fast switching and rectification in a minimal form factor, distinct from standard single-function MOSFETs or diodes.
Direct substitutes are limited due to the unique composite nature of the device. Verify if separate MOSFET and Schottky diode combinations can replicate the electrical characteristics and physical footprint. Check for equivalent parts from other manufacturers offering similar integrated N-channel MOSFET and SBD configurations.
