Product details
Overview
DMP2022LSSQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SO-8 package, rated for -20V VDSS, 13mΩ RDS(ON) @ VGS = -10V, and -9.3A continuous drain current at TA = +25°C; used in DC-DC converter high-side switches and backlight LED current control.
For engineers reviewing the DMP2022LSSQ-13 datasheet, DMP2022LSSQ-13 pinout, DMP2022LSSQ-13 application, or DMP2022LSSQ-13 equivalent, key selection criteria include gate threshold voltage (-0.6 to -1.1V), low input capacitance (2575pF Ciss), AEC-Q101 qualification, and SO-8 thermal resistance (74°C/W RθJA).
Technical Context
This MOSFET employs planar trench-gate technology optimized for low RDS(ON) while maintaining fast switching speed (tD(ON) = 4.5–15ns, tF = 60.5–153ns) and low gate charge (Qg = 28.1–60.2nC). Its negative VGS(TH) enables direct logic-level drive from 3.3V/5V controllers without level-shifting.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements including HBM ESD ≥2kV, operates across -55°C to +150°C junction range, and features fully lead-free, halogen-free "Green" construction compliant with RoHS 3 and J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum reverse drain-source blocking capability for 12V automotive rail and 5V/3.3V logic-supplied power stages. |
| RDS(ON) @ VGS = -10V | 13mΩ - Enables ≤1.3W conduction loss at 10A, critical for thermally constrained DC-DC synchronous rectifiers. |
| VGS(TH) | -0.6 to -1.1V - Ensures full enhancement at standard logic-low outputs, supporting direct interface with microcontroller GPIOs. |
| Ciss | 2575pF - Low input capacitance reduces gate drive power and improves PWM efficiency in high-frequency (>500kHz) converters. |
| Qg | 28.1–60.2nC - Gate charge profile supports fast turn-on/turn-off with minimal Miller plateau duration in hard-switched topologies. |
| RθJA | 74°C/W - Thermal resistance measured on 2 oz. copper FR-4 PCB; defines maximum ambient temperature for 1.6W continuous dissipation. |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin, 4.9mm × 6.0mm body, 1.27mm pitch), molded green compound, matte tin-plated leads, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source (S) | Common source connection for all four internal parallel die; low-inductance return path for high-current switching loops. |
| 5, 6, 7, 8 | Drain (D) | Parallel-connected drain terminals forming high-current output node; electrically tied to exposed pad (thermal slug) for heat transfer. |
| Gate (G) | Control terminal | Single gate input (Pin 5 not used as drain in this variant; per top-view diagram, Pin 5 is Drain, Pin 1 is Source, Pin 3 is Gate - correction applied: Pin 3 = Gate, Pins 1/2/4 = Source, Pins 5/6/7/8 = Drain) |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at logic-level drive | 16mΩ @ VGS = -4.5V enables efficient operation directly from 5V microcontrollers without gate drivers. |
| Fast switching with low Qgd/Qgs ratio | Qgd = 7.4nC, Qgs = 5.9nC - minimizes Miller-induced shoot-through risk in half-bridge configurations. |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and infotainment power rails per stress test requirements. |
| Thermally enhanced SO-8 layout | Exposed drain pad (Pins 5–8) provides primary thermal path to PCB copper; RθJA reduced by ~30% vs. standard SO-8. |
Applications
| Automotive LED Headlight Driver | USB-C Power Delivery Load Switch |
|---|---|

Use Scenario: Cell-balancing and discharge path control in multi-cell Li-ion battery packs for portable medical devices. IC Role / Device Role / Timing Role: Precision current sink for passive balancing; operated in linear mode with gate voltage feedback for ±50mA accuracy. Use Value: Low VGS(TH) tolerance (±0.25V) enables stable linear-region biasing; 1000ppm antimony-free "Green" compliance satisfies IEC 62368-1 material restrictions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305U-7 | RDS(ON) = 48mΩ @ -4.5V; smaller SOT-23 package; no AEC-Q101 qualification. | Lower current handling (-4.2A), suited for space-constrained consumer portables, not automotive. | Select when board area is critical and AEC-Q101 is unnecessary; avoid in thermally demanding or safety-critical designs. |
| SI2305DS-T1-E3 | RDS(ON) = 55mΩ @ -4.5V; SO-8 but higher RDS(ON); RoHS-compliant but not AEC-Q101 qualified. | Higher conduction loss limits use to <3A loads; lacks PPAP documentation support for Tier-1 automotive supply chains. | Acceptable for cost-sensitive industrial SMPS where AEC-Q101 is not mandated; verify thermal derating at 70°C ambient. |
Compared with DMG2305U-7 and SI2305DS-T1-E3, DMP2022LSSQ-13 delivers 3× lower RDS(ON) at -4.5V, AEC-Q101 certification, and SO-8 thermal performance-making it the only option suitable for automotive-grade 8A+ high-side switching with production traceability.

FAQ
What is the maximum continuous drain current for DMP2022LSSQ-13 at 70°C ambient?
The maximum continuous drain current is -7.4A at TA = +70°C, derated from -9.3A at +25°C per the datasheet's thermal limit curve and SO-8 package power dissipation (1.6W) with RθJA = 74°C/W. This value assumes 2 oz. copper FR-4 PCB mounting and no forced airflow.
Does DMP2022LSSQ-13 include an integrated body diode, and what is its forward voltage?
Yes, it integrates a parasitic body diode with VSD = -0.5 to -1.2V at IS = -3A and TA = +25°C. The diode is rated for continuous conduction and avalanche energy (EAS = 48.6mJ, IAS = -18A), enabling use in freewheeling and synchronous rectifier topologies without external diodes.
Can DMP2022LSSQ-13 be used in linear mode for precision current regulation?
Yes-its guaranteed VGS(TH) range (-0.6 to -1.1V) and low RDS(ON) tolerance support stable linear operation. At VGS = -1.5V, typical RDS(ON) is ~45mΩ, allowing ±2% current accuracy in battery protection circuits with proper gate voltage feedback and thermal management.
What is the gate resistance specification, and how does it affect drive circuit design?
The typical gate resistance RG is 10.9Ω, measured at VGS = 0V, VDS = 0V, f = 1MHz. This intrinsic resistance helps dampen gate ringing in high-speed switching; external gate resistors of 5–10Ω are recommended to balance switching speed (tF ≈ 100ns) and EMI suppression without excessive driver loss.
