Overview
The CMS3401-HF is a P-Channel Enhancement Mode MOSFET manufactured by Comchip Technology. It is housed in a SOT-23 surface-mount package and is RoHS compliant. The device features a drain-source voltage rating of -30V and a continuous drain current of -4.2A. At a gate-source voltage of 12V, the on-state resistance (RDS(on)) is specified at 78mΩ. The component has a power dissipation capability of 1.4W, making it suitable for low-power switching applications requiring compact packaging.
Feature Summary
- P-Channel enhancement mode operation for high-side or low-side switching configurations
- Low on-state resistance to minimize conduction losses
- Compact SOT-23 surface-mount package design
Applications
- Power management circuits
- High-speed switching applications
- Digital signal processing interfaces
Procurement Notes
Verify the specific suffix 'HF' indicates lead-free compliance and RoHS status as documented. Confirm the package type is SOT-23 and electrical parameters match the datasheet specifications for VDS, ID, and RDS(on). Ensure the manufacturer is Comchip Technology and check for active status availability through authorized channels.
Selection Notes
Select this component when a P-Channel MOSFET with -30V breakdown and -4.2A current capacity is required in a small SOT-23 footprint. Consider the 78mΩ RDS(on) at 12V VGS for efficiency requirements. Evaluate thermal performance given the 1.4W power dissipation limit in the target application environment.
Part Context
This part belongs to Comchip Technology's MOSFET product line, which includes various N-Channel and P-Channel devices. The series encompasses components with different voltage ratings and package types, such as the CMS79N10H8 and CJ3401-HF variants, catering to diverse power management needs.
Replacement Considerations
The CJ3401-HF is listed as a related MOSFET variant from the same manufacturer. Verify pinout compatibility and electrical parameter equivalence before substitution. No other public substitute part numbers are confirmed in the provided documentation.
