Overview
The DMP4065S-13 is a surface-mount P-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a -40V drain-source voltage rating and an on-resistance of 80mΩ at VGS=-10V/-4.2A, or 100mΩ at VGS=-4.5V/-3.3A. The device supports continuous drain currents up to -2.4A at +25°C (TA) and -3.4A at +25°C (TC). It operates within a junction temperature range of -55°C to +150°C and utilizes a SOT-23 package.
Feature Summary
- Designed for high-efficiency power management applications with minimized on-state resistance and superior switching performance.
- Compliant with JEDEC standards for high reliability and fully RoHS compliant without intentionally added lead.
- Constructed using a molded plastic case with UL flammability classification rating 94V-0.
Applications
- Battery Charging
- Power Management Functions
- DC-DC Converters
- Portable Power Adaptors
Procurement Notes
Verify the specific ordering suffix '-13' corresponds to the required tape and reel packaging quantity of 10,000 units per reel. Confirm that the standard SOT-23 case material and matte tin annealed over copper leadframe finish meet the thermal and solderability requirements of the target assembly process. Ensure the component meets the intended environmental specifications before final procurement.
Selection Notes
Select this component when a compact P-channel MOSFET with low on-resistance is required for portable power adaptors or DC-DC converters. Consider the -40V breakdown voltage and SOT-23 footprint constraints. Evaluate the gate threshold voltage characteristics against the available drive voltage levels in the circuit design to ensure reliable turn-on and optimal conduction efficiency under load conditions.
Part Context
This part belongs to the DMP4065S family of 40V P-channel enhancement mode MOSFETs produced by Diodes Incorporated. The product line focuses on providing low on-resistance and fast switching speeds suitable for modern power management architectures. The manufacturer offers automotive-compliant variants under separate datasheets for applications requiring specific change control and qualification standards.
Replacement Considerations
For automotive applications requiring specific change control, refer to the related automotive grade part with the Q-suffix (DMP4065SQ). Verify pinout compatibility and electrical parameters when substituting other 40V P-channel MOSFETs from different manufacturers.
FAQ
What is the maximum continuous drain current at +25°C ambient temperature?
The maximum continuous drain current is -2.4A at TA = +25°C.
Is this component qualified for automotive applications?
No, this specific part is not automotive qualified. For automotive applications requiring AEC-Q100/101/200 qualification, the DMP4065SQ variant should be used.
