Overview
The CMSP3139K-HF is a P-channel enhancement mode MOSFET manufactured by Comchip Technology. It features a Drain-Source Breakdown Voltage (Vds) of 20 V and a continuous Drain Current (Id) of 0.5 A at ambient temperature. The device utilizes an SOT-723-3 surface-mount package, offering a low profile suitable for high-speed mounting processes. Key electrical characteristics include a maximum Gate-Source Voltage (Vgs) of 10 V and a typical On-Resistance (Rds(on)) of approximately 399 mΩ. The component is designed for applications requiring extremely low switching loss and operates as a logic-level switch.
Feature Summary
- P-channel configuration with extremely low switching loss
- Logic-level gate drive operation capability
- Halogen-free and RoHS compliant construction
- Excellent stability and uniformity across devices
Applications
- Low voltage DC-DC converter circuits
- Battery protection modules
