Overview
The DMP31D7L is a P-channel enhancement mode MOSFET manufactured by Diodes Incorporated. It features a drain-source voltage (V_DSS) of -30 V and a maximum continuous drain current (I_D) of -0.58 A at +25°C. The device exhibits a static drain-source on-resistance (R_DS(ON)) of 0.9 Ω at V_GS = -10 V and 1.7 Ω at V_GS = -4.5 V. Total power dissipation is rated at 0.43 W with a thermal resistance (R_θJA) of 290 °C/W. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Low on-resistance for high-efficiency power management
- Fast switching speed with low input capacitance
- ESD protected gate structure
- Totally lead-free and fully RoHS compliant
Applications
- DC-DC Converters
- Power Management Functions
Procurement Notes
Verify the specific ordering suffix against official documentation, as packaging quantities vary between Tape & Reel options. Confirm that the component meets all applicable environmental directives and quality standards required for your specific design implementation before finalizing procurement.
Selection Notes
Select this component for applications requiring a compact SOT23 package with moderate current handling capabilities. Ensure the gate drive voltage aligns with the specified R_DS(ON) thresholds to optimize efficiency. Evaluate the thermal constraints carefully due to the limited power dissipation rating in the small outline package.
Part Context
This part belongs to the DMP series of P-channel MOSFETs designed for surface-mount applications. It utilizes a standard SOT23-3 mechanical package with matte tin annealed terminals over a copper leadframe. The device is classified as a 'Green' product, being halogen and antimony free.
Replacement Considerations
Consult official Diodes Incorporated documentation for qualified substitutes. Verify pinout compatibility and electrical parameters such as V_DSS and R_DS(ON) when considering alternative components.
