Product details
Overview
DMP2066LVT-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT26 package, rated for -20V VDS, 45 mΩ RDS(on) at VGS = -4.5V, and -4.5A continuous drain current at TA = +25°C. It features low gate threshold voltage (-0.4 to -1.5V), low input capacitance (1496 pF typ), and AEC-Q101 qualification-used in automotive power management and load switching circuits.
For engineers reviewing the DMP2066LVT-7 datasheet, DMP2066LVT-7 pinout, DMP2066LVT-7 application, or DMP2066LVT-7 equivalent, key selection criteria include verified RDS(on) at -2.5V gate drive, body diode forward voltage (-0.72V typ), thermal resistance (70°C/W with enhanced pad), and SOT26 terminal layout compatibility with space-constrained PCBs.
Technical Context
This MOSFET operates as a high-side load switch with gate-controlled conduction in negative-voltage referenced systems. Its low VGS(th) enables reliable turn-on from 2.5V logic rails, while its 14.4 nC total gate charge supports fast switching with minimal driver loss.
The device integrates a monolithic P-channel silicon die in a thermally optimized SOT26 package with exposed drain pads. Its RDS(on) increases predictably with junction temperature (72 mΩ max at +125°C), and its body diode exhibits low forward drop (-0.72V at -2.1A) for reverse-current handling in buck or OR-ing configurations.

Applications
| Automotive Body Control Module (BCM) | USB Power Delivery Switch |
|---|---|
Use Scenario: Controlling 12V lighting loads (LED lamps, interior lights) via microcontroller GPIO in vehicle BCM units. IC Role / Device Role / Timing Role: High-side load switch managing power delivery with fast turn-off to prevent backfeed during battery disconnect. Use Value: Low 45 mΩ RDS(on) limits voltage drop to <100 mV at 2A, preserving LED brightness; AEC-Q101 ensures reliability over 15-year vehicle lifetime. |
Use Scenario: Enabling/disabling VBUS path in USB Type-C PD sink applications with 5–20V input range. IC Role / Device Role / Timing Role: Reverse-polarity protected high-side switch isolating downstream circuitry during fault conditions. Use Value: -20V VDS rating safely handles 20V PD profiles; body diode forward voltage (-0.72V) minimizes conduction loss during dead-time in bidirectional designs. |
| Industrial Sensor Node Power Gating | Portable Medical Device Load Switch |
Use Scenario: Power gating of analog sensor front-ends (e.g., pressure, temperature) in battery-powered IIoT nodes. IC Role / Device Role / Timing Role: Low-quiescent current enable switch minimizing standby leakage (<1 µA IDSS at +55°C). Use Value: Gate threshold of -0.4V ensures full enhancement even with weak pull-up biasing, extending battery life beyond 5 years in sleep mode. |
Use Scenario: Isolating auxiliary subsystems (e.g., display backlight, wireless transceiver) in handheld diagnostic tools. IC Role / Device Role / Timing Role: Single-FET high-side switch replacing discrete PMOS+resistor solutions to reduce BOM count and board area. Use Value: SOT26 footprint (2.9 × 2.8 mm) saves >40% board space vs. SO-8 alternatives while maintaining 1.8W thermal capability. |
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 |
|---|---|---|---|
| DMG2305U-7 | RDS(on) = 48 mΩ @ -4.5V; higher Ciss (1700 pF); same SOT26 package | Slightly higher switching loss due to +14% Ciss; identical thermal performance | Preferred when second-source validation is required and minor gate charge increase is acceptable |
| AO3401A | RDS(on) = 52 mΩ @ -4.5V; lower VGS(th) (-0.3 to -1.0V); no AEC-Q101 qualification | Not suitable for automotive environments; better for cost-sensitive consumer electronics | Select only for non-automotive applications where AEC-Q101 is not mandated |
Compared with DMG2305U-7 and AO3401A, DMP2066LVT-7 delivers the lowest RDS(on) among SOT26 P-MOSFETs with AEC-Q101 certification, making it optimal for thermally constrained automotive and industrial power switches where conduction loss dominates efficiency.

FAQ
What is the maximum safe operating temperature for DMP2066LVT-7?
The device supports junction temperatures from -55°C to +150°C. With RθJA = 70°C/W (enhanced layout), it can dissipate 1.8W continuously at TA = +70°C before reaching TJ(max). Derating is required above 70°C ambient; full 1.8W rating applies only with 1-inch² copper pour per datasheet Note 6.
Can DMP2066LVT-7 be used in a low-side switching configuration?
No-it is a P-channel MOSFET optimized for high-side switching. In low-side configuration, the source would be grounded and gate driven negatively relative to source, which is incompatible with standard positive-rail logic drivers. N-channel devices like DMN2004K-7 are appropriate for low-side use.
Is the SOT26 package lead-free and RoHS-compliant?
Yes-DMP2066LVT-7 uses matte tin annealed over copper leadframe and green molding compound. It is fully RoHS 2 compliant (2011/65/EU), halogen-free (<900 ppm Br, <900 ppm Cl), and antimony-free per Diodes' "Green" definition, with MSL Level 1 moisture rating.
Does this MOSFET include an integrated ESD protection diode?
No-DMP2066LVT-7 has no built-in ESD protection circuitry. Its gate oxide withstands ±8V VGS absolute maximum, so external TVS or RC snubbers are recommended in high-noise environments such as automotive CAN/LIN bus proximity or motor drive adjacent routing.
