Product details
Overview
DMP2065UQ-13 from Diodes Incorporated is a 20V P-channel enhancement-mode MOSFET in SOT-23 package, rated for -4.0A continuous drain current at 25°C, with 60mΩ RDS(on) at VGS = -4.5V and AEC-Q101 qualified for automotive power switching. It delivers low gate threshold (-0.9V max), fast switching (tD(off) = 79.3ns), and operates from -55°C to +150°C.
For engineers reviewing the DMP2065UQ-13 datasheet, DMP2065UQ-13 pinout, DMP2065UQ-13 application, or DMP2065UQ-13 equivalent, key selection criteria include its -20V VDS, 60mΩ on-resistance at -4.5V drive, AEC-Q101 qualification, thermal resistance of 138°C/W (FR-4), and suitability for high-efficiency load switching in space-constrained automotive and industrial DC/DC subsystems.
Technical Context
This P-channel MOSFET uses silicon planar technology with optimized channel geometry to achieve low RDS(on) while maintaining robust avalanche capability and tight VGS(th) distribution (-0.5V to -0.9V). Its gate charge profile (Qg = 10.2nC) supports efficient PWM control in synchronous buck topologies and high-side load switches.
The device integrates an intrinsic body diode with VSD = -0.7V to -1.1V at -1A, enabling bidirectional current handling in reverse-polarity protection circuits. Its Ciss = 808pF and Crss = 77pF support stable operation in high-frequency (>1MHz) switching applications without excessive EMI generation.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305U-7 | RDS(on) = 48mΩ @ -4.5V; higher ID = -4.2A; same SOT-23 package | Slightly lower conduction loss but no AEC-Q101 qualification | Select for non-automotive industrial use where tighter RDS(on) is prioritized over automotive qualification |
| AO3401 | RDS(on) = 85mΩ @ -4.5V; lower cost; VGS(th) = -0.7V to -1.3V (wider spread) | Less consistent turn-on behavior across temperature; not AEC-Q101 qualified | Select for cost-sensitive consumer applications where gate drive margin and qualification are secondary |

FAQ
What is the maximum continuous drain current for DMP2065UQ-13 at 70°C ambient?
The maximum continuous drain current is -3.0A at TA = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the SOT-23 package on standard FR-4 PCB with minimum pad layout; improved copper area can extend usable current.
Is DMP2065UQ-13 suitable for reverse-polarity protection in 12V automotive systems?
Yes. With -20V VDS, -4.0A ID, and an integrated body diode (VSD = -0.7V to -1.1V), it functions as a low-loss reverse-polarity protector. Its AEC-Q101 qualification and -55°C to +150°C operating range meet automotive under-hood requirements.
Does DMP2065UQ-13 require a gate driver IC when driven by a 3.3V microcontroller?
No. Its VGS(th) max of -0.9V ensures full enhancement with 3.3V logic-level drive. However, a series gate resistor (e.g., 10Ω) is recommended to dampen ringing and control dV/dt during switching transitions.
How does the thermal resistance of DMP2065UQ-13 change with enhanced PCB layout?
RθJA improves from 138°C/W (standard FR-4, minimal pads) to 83°C/W with 2oz copper and a 1in² thermal pad on the bottom layer. This 40% reduction enables ~1.8× higher continuous current before reaching 150°C junction limit.
