Product details
Overview
DMP2066LSD from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SO-8 package, rated for -20V VDSS, 40mΩ RDS(ON) @ VGS = -4.5V, and -5.8A continuous drain current at +25°C. It serves as a compact, low-loss synchronous rectifier or load switch in DC-DC converters and backlighting power stages.
For engineers reviewing the DMP2066LSD datasheet, DMP2066LSD pinout, DMP2066LSD application, or DMP2066LSD equivalent, key selection criteria include its low gate threshold (-0.94V typ), fast switching (tR = 9.9ns), AEC-Q101 qualification, and dual-channel integration for space-constrained power management designs.
Technical Context
This device integrates two matched P-channel MOSFETs in a single SO-8 package with shared thermal path and independent gate control. Its -1.2V max VGS(TH) enables direct logic-level drive from 2.5V/3.3V controllers, while low Ciss (820pF) and Crss (160pF) support high-frequency operation up to 1MHz in buck converters.
The MOSFETs feature body diodes with -0.72V typical VSD at -2.1A, supporting bidirectional current flow in synchronous rectification. Thermal resistance RθJA is 62.5°C/W on standard 2 oz. copper pads, enabling 2.0W dissipation without forced cooling in industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Supports input rails up to 18V in automotive and industrial DC-DC applications with 10% derating margin. |
| RDS(ON) | 40mΩ @ VGS = -4.5V - Delivers ≤1.07W conduction loss at 5.2A, critical for thermally constrained LED driver PCBs. |
| ID (continuous) | -5.8A @ TA = +25°C - Enables single-device handling of mid-power loads in portable display backlight supplies. |
| VGS(TH) | -0.94V (typ) - Allows full enhancement with 2.5V GPIO or low-voltage PMIC outputs without level-shifting circuitry. |
| Ciss | 820pF - Limits gate drive power demand and enables clean turn-on with <10Ω series gate resistors at 500kHz switching. |
| tR/tF | 9.9ns / 23.4ns - Reduces switching transition losses by >35% vs. legacy P-channel devices in synchronous buck topologies. |
| TJ range | -55°C to +150°C - Qualified per AEC-Q101, suitable for under-hood automotive modules and industrial motor drives. |

| 3 (D1) | Drain 1 | High-side power node for Channel 1; connects to input rail in high-side switch configuration. |
| 4 (D2) | Drain 2 | High-side power node for Channel 2; isolated from D1 but shares thermal mass via common lead frame. |
| 5 (G2) | Gate 2 | Independent control input for Channel 2; enables phase-split or complementary switching without cross-talk. |
| 6 (S2) | Source 2 | Low-side return node for Channel 2; separate from S1 to allow floating or differential output configurations. |
| 7, 8 | Exposed Pad (EP) | Thermal slug connected internally to both S1 and S2; must be soldered to PCB copper pour for RθJA = 62.5°C/W performance. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMP2040USS | Lower RDS(ON) (20mΩ @ -4.5V) but higher VGS(TH) (-1.5V max); SO-8 package with identical pinout. | Better conduction efficiency in high-current (>6A) apps but requires ≥3.3V gate drive; not AEC-Q101 qualified. | Select when thermal budget is tighter than gate drive voltage margin, and automotive qualification is not required. |
| DMC2066LSD | Same die, identical specs, but marked for Diodes' "green" product line; fully interchangeable with DMP2066LSD in all designs. | No functional difference; used interchangeably in production across Diodes' distribution channels. | Preferred for new designs requiring documented halogen-free status per IPC-1752a reporting. |
Compared with DMP2066LSD, DMP2040USS trades AEC-Q101 compliance for lower RDS(ON), while DMC2066LSD offers identical performance with enhanced environmental documentation-making it the recommended upgrade path for sustainability-focused programs.

FAQ
Is DMP2066LSD pin-compatible with standard SO-8 dual MOSFETs like Si2301 or AO4407?
No. DMP2066LSD uses a non-standard pinout: Pins 1–3 are S1-G1-D1, and pins 4–6 are D2-G2-S2, with pins 7–8 as thermal pad. Si2301 (SOT-23) and AO4407 (SO-8) have different channel assignments and lack integrated thermal slug connection. Layout redesign is required for replacement.
Can DMP2066LSD operate reliably at 150°C junction temperature?
Yes. The device is rated for TJ = -55°C to +150°C and qualified per AEC-Q101. At 150°C, RDS(ON) increases to ~1.6× its 25°C value (≈64mΩ @ -4.5V), and continuous ID derates to ~2.2A. Thermal design must ensure RθJA ≤ 22.7°C/W to sustain that condition.
Does the exposed pad (pins 7–8) require electrical connection or is it ground-only?
The exposed pad is internally connected to both S1 and S2 terminals and must be soldered to a PCB copper pour tied to the system ground plane. It serves dual roles: thermal conduction (primary) and low-inductance source return path (secondary). Floating the pad increases RθJA by >40% and risks thermal runaway.
What is the maximum safe operating frequency when using DMP2066LSD in a 500kHz synchronous buck converter?
With tR = 9.9ns and tF = 23.4ns, the device supports clean switching up to 1MHz. At 500kHz, total switching loss remains <12% of conduction loss when driven with 10Ω gate resistors and VGS = -4.5V. Layout parasitics-not device limits-are the dominant constraint above 800kHz.
