Overview
The CPH3348-TL-E is a P-Channel Power MOSFET manufactured by onsemi, designed for surface-mount applications in the SOT-23-3 package. It features a drain-source breakdown voltage of 12 V and supports a continuous drain current of 3 A. The device exhibits a maximum on-resistance of 215 mOhms at specified gate-source voltages ranging from -10 V to 10 V. With a gate charge of 5.6 nC and threshold voltage of 1.4 V, it offers efficient switching capabilities. The component operates within a temperature range of -55°C to +150°C and handles up to 1 W of power dissipation.
Feature Summary
- Single-channel enhancement mode P-Channel configuration
- Low on-resistance for efficient power handling
- High-speed switching with defined rise and fall times
Applications
- Power management circuits requiring low-side or high-side switching
- DC-DC converter output stages
- Load switch applications in portable electronics
Procurement Notes
Verify the specific suffix against official documentation, as the provided model includes an 'E' variant which may differ from the standard TL-W version regarding tape and reel specifications or compliance status. Confirm availability through authorized distributors, noting that some variants may be subject to end-of-life notices or regional distribution restrictions. Ensure the ordering part number matches the exact package and marking requirements for your design.
Selection Notes
Select this component when a compact P-Channel MOSFET with moderate current capability is required. The SOT-23-3 package suits space-constrained designs. Evaluate the 215 mOhm on-resistance against thermal constraints for the expected load current. Ensure the 12 V voltage rating exceeds the maximum circuit voltage with appropriate safety margins. Consider the gate charge characteristics for driving efficiency in high-frequency switching applications.
Part Context
This part belongs to the CPH3348 series of power MOSFETs from onsemi. The series focuses on providing reliable switching performance in small surface-mount packages. The CPH3348-TL-E variant specifically denotes the P-Channel type within this lineup, sharing common electrical characteristics with other suffixes but potentially differing in packaging or manufacturing lot details.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with any alternative components by matching the pinout, voltage ratings, current capacity, and package dimensions strictly against the official datasheet specifications.
