Procurement Notes
Verify the exact datasheet revision and electrical characteristics directly from onsemi official documentation before integration. Confirm that the SOT-23-3 package dimensions match your PCB footprint requirements. Ensure thermal management strategies align with the specific power dissipation limits defined in the manufacturer's specifications for your operating environment.
Selection Notes
Select this component when a P-channel MOSFET is required for low-side or high-side switching in 4V logic-compatible environments. Compare specific on-resistance and gate charge parameters against alternative devices to ensure compatibility with your controller's drive capability. Validate that the voltage ratings exceed the maximum circuit supply voltage under all transient conditions.
Part Context
This part belongs to onsemi's discrete transistor portfolio, specifically categorized under RF and small-signal MOSFETs. The CPH series is engineered for compact form factors and low power consumption. It complements other components in power supply designs where space constraints and efficiency are critical design drivers for modern consumer electronics.
Replacement Considerations
Consult onsemi official substitution guides for verified alternatives. Ensure any replacement maintains identical pinout, voltage ratings, and thermal performance characteristics to guarantee circuit functionality without redesign.
