Product details
Overview
DMP3165LQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -30V VDSS, 90mΩ RDS(ON) @ VGS = -10V, and -3.3A continuous drain current at TA = +25°C. It delivers low gate threshold (-1.3 to -2.1V), fast switching (tF = 8.4ns), and AEC-Q101 qualification for automotive power management.
For engineers reviewing the DMP3165LQ-13 datasheet, DMP3165LQ-13 pinout, DMP3165LQ-13 application, or DMP3165LQ-13 equivalent, key selection criteria include its -30V breakdown voltage, 90mΩ on-resistance at -10V gate drive, SOT23 thermal resistance (RθJA = 159°C/W), AEC-Q101 qualification, and suitability for high-efficiency DC-DC converter topologies requiring compact, lead-free, halogen-free P-channel switches.
Technical Context
This MOSFET operates as a high-side load switch or synchronous rectifier in buck converters, leveraging its low RDS(ON) and fast turn-off (tD(OFF) = 13.6ns) to minimize conduction and switching losses. Its -2.1V max VGS(TH) ensures reliable turn-on with standard 3.3V/5V logic-level gate drivers.
The device integrates a body diode with VSD = -0.83V @ IS = -2.7A and tRR = 6.5ns, supporting efficient freewheeling in discontinuous conduction mode. Its Ciss = 300pF and Qg = 2.0nC @ VGS = -10V enable stable gate drive with minimal Miller effect in high-frequency (>1MHz) power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Withstands up to -30V drain-source voltage before avalanche breakdown, enabling use in 24V automotive and industrial bus applications. |
| RDS(ON) | 90mΩ @ VGS = -10V - Delivers <0.8W conduction loss at -2.7A, critical for thermally constrained SOT23 footprint designs. |
| ID (continuous) | -3.3A @ TA = +25°C - Supports moderate-power load switching without external heatsinking on standard FR-4 PCBs. |
| VGS(TH) | -1.3 to -2.1V - Ensures full enhancement with 3.3V microcontroller GPIO or logic-level drivers, reducing need for level-shifting circuitry. |
| tF | 8.4ns - Enables >5MHz switching frequencies while maintaining low EMI and minimizing dead-time losses in synchronous rectification. |
| Ciss | 300pF @ VDS = -10V - Limits gate drive current demand and improves noise immunity in noisy automotive environments. |
| Qg | 2.0nC @ VGS = -10V - Reduces gate driver power consumption and simplifies gate resistor selection for fast, controlled edge rates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG3415L-7 | RDS(ON) = 50mΩ @ -4.5V (lower), but VDSS = -20V (reduced voltage margin) | Better suited for 12V systems where lower on-resistance outweighs voltage derating needs | Select when prioritizing conduction loss over 24V+ bus compatibility |
| AO3401 | RDS(ON) = 85mΩ @ -4.5V (comparable), but not AEC-Q101 qualified and higher Qg = 3.5nC | Acceptable for consumer-grade portable electronics but unsuitable for automotive or medical BOMs requiring qualification | Choose only for cost-sensitive non-automotive applications with relaxed reliability requirements |
Compared with DMG3415L-7 and AO3401, DMP3165LQ-13 uniquely balances -30V robustness, AEC-Q101 qualification, and 134mΩ RDS(ON) @ -4.5V-making it optimal for automotive body electronics and industrial 24V systems where voltage margin and process certification are non-negotiable.

FAQ
What is the maximum safe operating temperature for DMP3165LQ-13?
The DMP3165LQ-13 has a specified junction temperature range of -55°C to +150°C. Its thermal resistance is RθJA = 159°C/W on standard FR-4 board (2oz copper, minimum pad layout). At 2.7A and 90mΩ RDS(ON), power dissipation is ~0.65W, resulting in ~103°C junction rise above ambient-well within the 150°C limit if ambient stays below 47°C.
Does DMP3165LQ-13 require a gate resistor for stability?
Yes-a series gate resistor (typically 10–47Ω) is recommended to dampen ringing caused by the 12.5Ω gate resistance and 300pF input capacitance. Without it, fast edges may induce oscillation due to PCB trace inductance, especially in high-noise automotive environments where EMI immunity is critical.
Can DMP3165LQ-13 be used in synchronous rectification?
Yes-the device's 6.5ns reverse recovery time, 1.2nC QRR, and low VSD (-0.83V) make it suitable for synchronous rectification in buck converters up to ~2MHz. However, its -30V rating limits use to ≤12V output stages unless secondary-side voltage clamping is implemented.
How does the SOT23 package affect thermal performance in continuous operation?
In continuous operation, the SOT23 package limits power dissipation to 0.8W (PD) at TA = +25°C due to RθJA = 159°C/W. To sustain -3.3A continuously, ambient must remain ≤40°C or PCB copper area must be increased (e.g., 1-inch² copper plate lowers RθJA to 98°C/W, enabling 1.3W dissipation).
