Product details
Overview
DMP4065SQ-13 from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in SOT23 package, rated for -3.4A continuous drain current at VGS = -10V, with RDS(ON) = 80mΩ (max), AEC-Q101 qualified, and designed for automotive battery charging and DC-DC converter power switches.
For engineers reviewing the DMP4065SQ-13 datasheet, DMP4065SQ-13 pinout, DMP4065SQ-13 application, or DMP4065SQ-13 equivalent, this part supports high-reliability automotive power management where low on-resistance, fast switching, and IATF 16949-manufactured traceability are required.
Technical Context
This P-channel MOSFET operates with gate threshold voltage VGS(TH) between -1.0V and -3.0V, enabling robust turn-on control in high-side switch configurations. Its low input capacitance (Ciss = 587pF) and fast switching times (tD(ON) = 3.6ns, tF = 15.3ns) support efficient operation in synchronous buck and load-switch topologies.
The device integrates an intrinsic body diode with VSD = -0.7V to -1.2V at IS = -1A, and exhibits normalized RDS(ON) variation of ≤1.5× across -55°C to +150°C junction temperature, ensuring stable conduction in thermally demanding automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40V - Withstands up to 40V reverse drain-source voltage without breakdown. |
| RDS(ON) | 80mΩ @ VGS = -10V - Enables <0.8W conduction loss at 3.2A DC current. |
| ID (max) | -3.4A @ TA = +25°C - Supports compact high-side load switching in space-constrained PCBs. |
| Qg | 12.2nC @ VGS = -10V - Low gate charge reduces driver power and enables >1MHz PWM operation. |
| RθJA | 90°C/W (with 1"² copper) - Allows 1.4W power dissipation at +70°C ambient with standard layout. |
| VGS(TH) | -1.0V to -3.0V - Ensures reliable turn-on with 3.3V or 5V logic-level gate drive. |
| Ciss | 587pF - Minimizes Miller effect and improves EMI performance in fast-switching converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305U-7 | RDS(ON) = 48mΩ @ -4.5V (lower), but VDSS = -20V (halved) | Not suitable for 36V automotive transients; limited to 12V/24V low-voltage rails | Select only if system VIN ≤ 20V and lower on-resistance is critical. |
| AO3401 | RDS(ON) = 85mΩ @ -4.5V, same VDSS, but not AEC-Q101 qualified | Lacks PPAP documentation and IATF 16949 traceability for automotive production | Acceptable for industrial or consumer designs where automotive qualification is not mandated. |
Compared with DMG2305U-7 and AO3401, DMP4065SQ-13 uniquely combines -40V rating, AEC-Q101 qualification, and 80mΩ RDS(ON) in SOT23-making it the only option for cost-sensitive, space-constrained automotive high-side switches requiring transient robustness and supply-chain compliance.

FAQ
What is the maximum continuous drain current for DMP4065SQ-13 at 70°C ambient?
The DMP4065SQ-13 delivers -2.7A continuous drain current at TA = +70°C when mounted on an FR-4 board with 1-inch² copper pour (RθJA = 90°C/W). This derating reflects thermal limits under real-world PCB layout conditions, not just die capability.
Does DMP4065SQ-13 include a body diode, and what is its forward voltage?
Yes, DMP4065SQ-13 integrates a parasitic body diode with typical forward voltage VSD = -0.7V at IS = -1A and TA = +25°C. The diode is rated for -14A avalanche current and supports freewheeling in buck and flyback topologies.
Can DMP4065SQ-13 be driven directly by a 3.3V microcontroller GPIO?
No-its VGS(TH) range (-1.0V to -3.0V) requires negative gate drive relative to source. A 3.3V GPIO cannot produce sufficient |VGS|; a dedicated gate driver or level-shifting circuit is required to generate ≥-4.5V gate voltage for full RDS(ON) performance.
Is DMP4065SQ-13 suitable for hot-swap applications?
Yes-its -40V VDSS, low leakage (<1μA), and controlled turn-on characteristics support hot-swap functionality in 12V/24V systems. However, external current-limiting circuitry is recommended, as the device lacks integrated slew-rate control or fault reporting.
