Product details
Overview
DMP2066LVT-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET optimized for low-voltage power switching in space-constrained applications, featuring -20V V(BR)DSS, 45mΩ RDS(ON) @ VGS = -4.5V, -4.5A ID max at TA = +25°C, and SOT26 package. It serves as a high-efficiency load switch in portable power rails and battery protection circuits.
For engineers reviewing the DMP2066LVT-13 datasheet, DMP2066LVT-13 pinout, DMP2066LVT-13 application, or DMP2066LVT-13 equivalent, key selection criteria include gate threshold voltage (-0.4V to -1.5V), low input capacitance (1496pF typ), thermal resistance (100°C/W on FR-4), AEC-Q101 qualification, and RoHS/Green compliance.
Technical Context
This MOSFET employs planar trench-gate technology to achieve low RDS(ON) while maintaining fast switching performance. Its -1.5V maximum VGS(th) enables reliable turn-on with 2.5V–3.3V logic-level drive, and its 2.7nC QGD supports efficient PWM operation in DC-DC converters.
The device integrates a body diode with VF = -0.72V @ IS = -2.1A and exhibits stable RDS(ON) up to +125°C (72mΩ max), making it suitable for thermally demanding industrial and automotive environments where junction temperature may exceed 100°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | -20V - Withstands reverse drain-source voltage up to -20V without breakdown, enabling use in 12V and 15V rail protection. |
| RDS(ON) | 45mΩ @ VGS = -4.5V - Delivers <200mW conduction loss at -4.5A, critical for high-efficiency battery-powered systems. |
| ID max | -4.5A @ TA = +25°C - Supports continuous load switching for USB PD, e-fuse, and hot-swap applications. |
| VGS(th) | -0.4V to -1.5V - Ensures full enhancement with 2.5V/3.3V microcontroller GPIOs, eliminating need for level-shifting. |
| Ciss | 1496pF typ @ VDS = -15V - Low input capacitance reduces gate drive power and improves switching speed in high-frequency SMPS. |
| QG | 14.4nC typ - Enables fast turn-on with minimal gate driver current, supporting >500kHz PWM in compact DC-DC designs. |
| RθJA | 100°C/W (FR-4, 2oz Cu) - Defines thermal derating curve: max 1.2W dissipation at ambient ≤+55°C with standard PCB layout. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305U-7 | RDS(ON) = 48mΩ @ VGS = -4.5V; SOT-23 package; no AEC-Q101 qualification | Limited to commercial-temp consumer electronics due to -55°C to +150°C rating but no automotive validation | Select when board space is tighter (SOT-23 vs SOT-26) and AEC-Q101 is not required. |
| SI2305DS-T1-GE3 | RDS(ON) = 55mΩ @ VGS = -4.5V; higher QG (20nC); RoHS-compliant but not halogen-free | Suitable for cost-sensitive industrial controls where green compliance is secondary to price | Choose for legacy designs using Vishay footprint; verify thermal margin due to higher RDS(ON) and QG. |

FAQ
What is the maximum continuous drain current for DMP2066LVT-13 at +70°C ambient?
The maximum continuous drain current is -3.7A at TA = +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations on a standard FR-4 PCB with 2oz copper and minimum recommended pad layout; actual current capability increases with enhanced copper area or forced airflow.
Does DMP2066LVT-13 support reverse polarity protection without external components?
Yes-the integrated body diode and -20V V(BR)DSS rating allow direct implementation of reverse-polarity protection in 12V systems. When placed between input and load with source to input, it blocks reverse current flow while conducting forward current with only -0.72V VF at -2.1A, eliminating need for additional diodes or controllers.
Is the SOT26 package of DMP2066LVT-13 compatible with standard SOT-23 reflow profiles?
Yes-TSOT26 uses the same JEDEC-standard reflow profile as SOT-23. Its moisture sensitivity level 1 allows floor life unlimited at ≤30°C/60% RH, and the matte tin annealed finish ensures solderability per MIL-STD-202, Method 208 without pre-baking.
How does the gate threshold voltage affect drive compatibility with 3.3V microcontrollers?
With VGS(th) ranging from -0.4V to -1.5V, DMP2066LVT-13 fully enhances at VGS = -3.3V (i.e., gate driven 3.3V below source), ensuring robust conduction even with marginal gate drive. This eliminates shoot-through risk and simplifies interface design versus higher-threshold P-MOSFETs requiring negative bias generation.
