Product details
Overview
DMS2220LFW-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET integrated with a low-VF Super Barrier Rectifier (SBR) in a single DFN3020-8 package. It delivers -2.9 A continuous drain current, -20 V VDSS, 95 mΩ RDS(on) at VGS = -4.5 V, and 35 V SBR reverse voltage - enabling compact, high-efficiency synchronous rectification and reverse-polarity protection in space-constrained DC/DC converters.
For engineers reviewing the DMS2220LFW-7 datasheet, DMS2220LFW-7 pinout, DMS2220LFW-7 application, or DMS2220LFW-7 equivalent, key selection criteria include its dual-function integration (MOSFET + SBR), AEC-Q101 qualification, ultra-low profile (0.5 mm max height), and gate threshold of -1.3 V max - critical for 3.3 V and 5 V logic-level control in automotive body electronics and industrial power modules.
Technical Context
This device integrates two independent semiconductor functions: a P-channel MOSFET (Q1) with VGS(th) ≤ -1.3 V and RDS(on) as low as 86 mΩ (typ) at VGS = -1.8 V, and a co-packaged SBR diode (D1) rated for 35 V VRRM and 1 A IO. Both share thermal coupling but operate electrically isolated per internal schematic.
The DFN3020-8 package features an exposed thermal pad (A3 = 0.15 mm typ) and NiPdAu-plated terminals, supporting 1.5 W power dissipation at TA = 25°C with RθJA = 85°C/W on FR-4 with minimum copper pad layout. Its AEC-Q101 qualification confirms suitability for automotive under-hood applications up to 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - Maximum blocking voltage for reverse-polarity protection and high-side switching in 12 V automotive systems. |
| RDS(on) | 95 mΩ @ VGS = -4.5 V - Enables <100 mW conduction loss at 1 A load, critical for thermally constrained PCB layouts. |
| ID | -2.9 A - Continuous drain current rating supports 3 A-class load switching without external heatsinking. |
| VRRM (SBR) | 35 V - Supports 24 V nominal input rails with 50% safety margin against transients in industrial SMPS. |
| VF (SBR) | 0.49 V @ IF = 1.0 A - Reduces forward drop by ~30% vs. standard Schottky, lowering rectifier losses in buck output stages. |
| TJ Range | -55°C to +150°C - Validated operation across full automotive temperature range per AEC-Q101 stress testing. |
| Package | DFN3020-8 - 3.0 × 2.0 mm footprint with 0.5 mm max height, compatible with automated optical inspection and reflow profiles. |
Pinout & Package
DFN3020-8 package with 8-terminal configuration and exposed thermal pad (pin 8). Terminals are arranged in dual-row layout with G, A, K, S, D, A, K, K labeling per top-view schematic. Pin 1 (G) is gate; pins 2/3/6/7 (A/K) are SBR anode/cathode connections; pins 4/5 (S/D) are MOSFET source/drain; pin 8 is thermal pad (electrically connected to source).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | MOSFET Gate | Logic-level control input; -1.3 V max VGS(th) ensures turn-on with 3.3 V microcontroller GPIO. |
| 2, 3, 6, 7 (A/K) | SBR Anode/Cathode | Four parallel SBR terminals reduce effective series resistance and improve current sharing in high-reliability rectification. |
| 4 (S) | MOSFET Source | Common reference node for both MOSFET and SBR; tied to thermal pad (pin 8) for optimal heat transfer. |
| 5 (D) | MOSFET Drain | High-side switch node; connects to input rail in reverse-voltage protection circuits. |
| 8 (Thermal Pad) | Source Thermal Connection | Electrically tied to source (pin 4); must be soldered to PCB copper pour for RθJA = 85°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated SBR + MOSFET | Single-package solution eliminates discrete layout mismatch, reduces parasitic inductance, and cuts BOM count by 2 devices. |
| Low RDS(on) at 1.8 V drive | 86 mΩ (typ) enables direct interface with low-voltage MCUs and battery-powered controllers without level-shifting. |
| AEC-Q101 qualified | Validated for automotive applications including door modules, lighting drivers, and engine control peripherals. |
| 0.5 mm max height | Enables use in ultra-thin consumer power banks and wearable device chargers where Z-axis clearance is limited. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-function MOSFET+SBR applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2020LFD-7 | Same DFN3020-8 package, but N-channel (-20 V VDSS) with no integrated SBR; RDS(on) = 42 mΩ @ VGS = 4.5 V. | Requires external SBR diode and high-side gate driver; unsuitable for reverse-polarity protection without redesign. | Select when higher efficiency at 4.5 V drive is prioritized and board space allows separate rectifier placement. |
| DMT6009LSD-13 | P-channel (-20 V), RDS(on) = 9.5 mΩ @ VGS = -4.5 V, SO-8 package, no integrated SBR. | Larger footprint and higher profile (1.75 mm); lacks AEC-Q101 qualification and SBR integration. | Choose for legacy SO-8 compatibility or when lower RDS(on) justifies added board area and component count. |
Compared with DMN2020LFD-7 and DMT6009LSD-13, DMS2220LFW-7 uniquely combines AEC-Q101 compliance, integrated SBR, and ultra-low profile in one package - reducing design complexity and bill-of-materials cost for automotive and portable power applications requiring both switching and rectification.

FAQ
What is the maximum continuous drain current for DMS2220LFW-7?
The DMS2220LFW-7 is rated for -2.9 A continuous drain current (ID) at TA = 25°C with proper PCB copper pad layout per datasheet note 1. At elevated ambient temperatures, derating applies - e.g., ~1.8 A at 85°C ambient with 1.5 W power limit and RθJA = 85°C/W.
How is the SBR function electrically isolated from the MOSFET?
The SBR (D1) and MOSFET (Q1) share no internal electrical connection; they are monolithically integrated but operate as independent devices. The SBR anode and cathode terminals (pins 2,3,6,7) are isolated from MOSFET drain/source (pins 4,5), confirmed by the internal schematic showing separate symbol blocks and test conditions specifying independent parameter measurements.
Can DMS2220LFW-7 be used in a high-side switch configuration?
Yes - its P-channel architecture and -1.3 V max gate threshold enable direct high-side switching with 3.3 V or 5 V logic control. When used as a high-side switch, the source connects to the positive rail, drain to the load, and gate driven low to turn on; the integrated SBR provides inherent freewheeling path during inductive load turn-off.
Is the thermal pad (pin 8) electrically connected, and how should it be handled?
Yes, the exposed thermal pad (pin 8) is internally connected to the MOSFET source (pin 4) and must be soldered to a PCB copper pour for thermal performance. Per datasheet, this connection is required to achieve the specified RθJA = 85°C/W; floating or unconnected thermal pads increase junction temperature by >30°C at rated power.
