Overview
The CPH3350-TL-H is a P-Channel Power MOSFET from onsemi, designed for general-purpose switching applications. It features a -20V drain-source voltage and a continuous drain current of -3A. The device exhibits an on-state resistance of 83mΩ and supports 1.8V drive levels. Packaged in a surface-mount SOT-23 (CPH) format with three pins, it operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 1W.
Feature Summary
- Ultrahigh-speed switching capability
- Compatible with 1.8V drive logic
- Halogen-free compliance
Applications
- Load switch circuits
- General-purpose switching devices
Procurement Notes
Verify the specific suffix 'TL-H' against the official datasheet to confirm tape-and-reel packaging and halogen-free status. Confirm availability as this component may be subject to end-of-life or discontinuation notices. Ensure the ordering part number matches the exact electrical specifications required for your design before procurement.
Selection Notes
Select this component for low-voltage, high-current switching tasks requiring fast response times. The 1.8V gate drive compatibility makes it suitable for modern low-power control systems. Consider the 83mΩ on-resistance for efficiency requirements and the SOT-23 package for space-constrained PCB layouts.
Part Context
This part belongs to the CPH3455/CPH3350 series of single-channel MOSFETs. It shares the CPH package family with similar N-Channel variants like the CPH3455. The series is characterized by compact surface-mount packaging and optimized switching performance for portable and industrial electronics.
Replacement Considerations
Check for direct substitutes such as the CPH3350-TL-W, noting potential differences in packaging quantity or specific compliance certifications. Verify that any replacement maintains the -20V/Vds and -3A/Id ratings.
