Overview
The onsemi CPH3449-TL-E is an N-channel MOSFET designed for surface-mount applications. It features a low gate drive voltage capability of 2.5V, making it suitable for battery-powered systems. The component utilizes the compact CPH package with six pins. Key electrical parameters include a drain-source voltage (Vds) rating of 25V and a continuous drain current (Ids) range of 20 to 40 mA. The device supports a maximum power dissipation (Pd) of 400mW. It operates within a temperature range from -55°C to 150°C.
Feature Summary
- Low gate drive voltage support for efficient operation in low-voltage environments
- Compact surface-mount packaging for space-constrained designs
- High thermal stability with extended operating temperature range
Applications
- Battery-powered portable electronics
- Low-voltage signal switching circuits
- Power management modules in consumer devices
Procurement Notes
Verify the specific suffix and tape-and-reel configuration against the official datasheet before ordering. Confirm RoHS compliance status and material composition declarations are current. Ensure the selected distributor provides traceable documentation matching the manufacturer's part identification. Check for any obsolescence notices or lifecycle changes directly from onsemi sources.
Selection Notes
Select this component when a small-form-factor N-channel MOSFET with 2.5V logic compatibility is required. Evaluate the 25V breakdown voltage and current handling against circuit load requirements. Consider the CPH package dimensions for PCB layout constraints. Verify thermal performance under expected duty cycles to ensure operation within the 400mW dissipation limit.
Part Context
This part belongs to the CPH series of discrete semiconductors from onsemi, focusing on small-signal switching applications. The series emphasizes miniaturization and efficiency for modern electronic devices. It complements other low-power transistors in the portfolio, targeting markets requiring reliable performance in compact form factors.
Replacement Considerations
Consult the official onsemi datasheet for direct pin-compatible substitutes. Verify that alternative parts match the 2.5V drive requirement and 25V Vds rating. Cross-reference package dimensions to ensure mechanical fit without redesigning the footprint.
