Procurement Notes
Verify the specific suffix against official documentation, as the TL-W variant is documented while the TL-H status requires confirmation. Confirm RoHS compliance and REACH SVHC details via the manufacturer's datasheet. Ensure the component meets required automotive or industrial reliability standards if applicable to the design.
Selection Notes
Select this component for low-voltage P-Channel switching requirements where a 30 V rating and 2.5 A current capacity are sufficient. Consider the SOT-23-3 footprint for space-constrained designs. Verify that the 4 V threshold voltage aligns with the logic level control signals available in the target system architecture.
Part Context
This part belongs to the CPH3355 series of single-channel MOSFETs from onsemi. The series includes variants such as CPH3355-TL-W. These devices are designed for general-purpose switching tasks in consumer and industrial electronics, offering a balance of performance and compact packaging.
Replacement Considerations
Cross-reference with other P-Channel MOSFETs in the SOT-23-3 package. Verify pinout compatibility and ensure equivalent or superior electrical ratings for Vds, Id, and Rds(on) before substitution.
