Overview
The onsemi CPH6347-TL-HX is a single P-Channel Power MOSFET designed for general-purpose switching applications. It features a drain-source voltage (Vdss) of -20 V and a continuous drain current (Id) of -6 A at ambient temperature. The device exhibits a maximum on-resistance (Rds(on)) of 39 mΩ, ensuring efficient power handling. It operates with gate drive voltages as low as 1.8 V, facilitating compatibility with low-voltage logic interfaces. The component is housed in a compact 6-pin CPH package, suitable for surface-mount assembly.
Feature Summary
- P-Channel configuration optimized for low-side or high-side switching topologies
- Low on-resistance characteristic minimizes conduction losses during operation
- Compatible with standard logic-level gate drive signals for simplified control
Applications
- DC-DC power supply circuits
- General purpose switching applications
- Power management systems
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact binning or tape-and-reel specifications. Confirm that the requested part number matches the active or obsolete status indicated in current distributor catalogs. Ensure compatibility with existing PCB footprints for the 6-CPH package before finalizing procurement decisions.
Selection Notes
Select this component when a -20 V rating and -6 A current capacity are required for P-Channel switching. Consider the 39 mΩ on-resistance for thermal management requirements in space-constrained designs. Evaluate the 1.8 V gate drive threshold against the available control logic voltage levels to ensure reliable turn-on performance.
Part Context
This device belongs to the discrete MOSFET category within onsemi's portfolio. It serves as a standalone switching element rather than an integrated module. The CPH package provides a compact form factor compared to traditional through-hole alternatives, supporting modern surface-mount manufacturing processes.
Replacement Considerations
Public records indicate the variant CPH6347-TL-H is a related version. Verify pinout and electrical parameter equivalence before substitution. No other direct substitute part numbers are confirmed in public documentation.
