Product details
Overview
DMP2067LSS from Diodes Incorporated is a P-channel enhancement-mode MOSFET designed for high-efficiency power management, featuring -20V VDSS, 38 mΩ RDS(ON) @ VGS = -4.5V, and -5.4A continuous drain current at TA = +25°C. It serves as a low-side load switch or synchronous rectifier in compact DC-DC converters and LED backlight drivers.
For engineers reviewing the DMP2067LSS datasheet, DMP2067LSS pinout, DMP2067LSS application, or DMP2067LSS equivalent, key selection criteria include gate threshold voltage (-0.5 to -1.5 V), thermal resistance (75 °C/W with enhanced pad layout), and SO-8 package compatibility with standard PCB assembly processes.
Technical Context
This MOSFET operates in enhancement mode with negative gate control logic, requiring VGS ≤ -0.5 V to initiate conduction and fully enhancing at VGS = -4.5 V. Its low RDS(ON) and 1575 pF Ciss support fast switching in buck converter high-side or low-side configurations.
The device integrates a body diode with VSD = -0.7 V @ IS = -2.1 A and tRR = 13 ns, enabling efficient freewheeling in synchronous rectification. Thermal design leverages the exposed drain pad for RθJC = 14 °C/W junction-to-case transfer.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - maximum blocking voltage in off-state, suitable for 12 V rail systems with margin |
| RDS(ON) | 38 mΩ @ VGS = -4.5V - enables <190 mW conduction loss at 5.4 A, critical for thermal budget in space-constrained designs |
| VGS(TH) | -0.5 to -1.5 V - ensures reliable turn-on with standard 3.3 V or 5 V logic-level gate drivers |
| Ciss | 1575 pF - determines gate drive energy requirement (~27.9 nC total Qg) and impacts switching speed |
| PD (enhanced layout) | 1.67 W - supports ~22 °C temperature rise above ambient with 2 oz copper thermal bias |
| tRR | 13 ns - minimizes reverse recovery losses during hard commutation in synchronous buck topologies |
Pinout & Package
Package: SO-8 surface-mount package with exposed drain pad for thermal dissipation; compliant with JEDEC MS-012AC, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 6, 7, 8 | Drain (D) | Internally connected to exposed pad - primary current path and thermal conduction path to PCB |
| 5 | Gate (G) | Control terminal; requires negative voltage relative to source to conduct; low input capacitance enables fast edge rates |
| Source (S) | Source (S) | Reference node for gate drive; tied to system ground or high-side return in floating configurations |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at logic-level drive | 38 mΩ @ VGS = -4.5V enables use with 3.3 V microcontrollers without level-shifting circuitry |
| Low gate threshold voltage | VGS(TH) down to -0.5 V ensures robust turn-on even under supply droop or temperature variation |
| Fast switching performance | tD(ON) = 5.2 ns and tF = 30.7 ns reduce transition losses in high-frequency (>500 kHz) DC-DC stages |
| Enhanced thermal capability | RθJA = 75 °C/W with optimized 2 oz copper layout allows >1.6 W power dissipation in compact footprints |
Applications
| LED Backlight Control | USB Power Delivery Switch |
|---|---|
Use Scenario: Driving parallel white LED strings in notebook displays using PWM dimming at 1–20 kHz. IC Role / Device Role: Low-side current sink switch controlling LED cathode return path. Use Value: 38 mΩ RDS(ON) limits conduction loss to <110 mW per string at 2 A, reducing thermal stress on FPC flex circuits. | Use Scenario: Enabling/disabling 5 V/3 A USB Type-C power path in portable docking stations. IC Role / Device Role: Load switch isolating downstream ports during fault conditions or hot-plug events. Use Value: -1.5 V VGS(TH) max ensures full enhancement with 3.3 V GPIO control, eliminating need for external charge pump. |
| Point-of-Load Synchronous Rectifier | Industrial Sensor Power Gate |
Use Scenario: Replacing Schottky diode in 12 V → 3.3 V buck converter for PLC I/O modules. IC Role / Device Role: Synchronous rectifier in low-side position, driven by controller's complementary output. Use Value: 13 ns tRR and low QRR (6.3 nC) suppress voltage spikes and reduce EMI during dead-time transitions. | Use Scenario: Power gating 24 V analog sensor supplies in factory automation nodes to meet standby current <10 µA. IC Role / Device Role: High-side or low-side power switch controlled by isolated digital signal. Use Value: -100 nA IDSS leakage at -16 V ensures <1 µA total system standby drain, meeting IEC 62368-1 sleep mode requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG2305UVT-7 | RDS(ON) = 45 mΩ @ -4.5 V; higher Ciss (1720 pF); same SO-8 package | Marginally higher conduction loss; less suitable for >1 MHz switching due to higher gate charge | Prefer when cost sensitivity outweighs efficiency targets in 300–500 kHz converters |
| SI2305DS-T1-E3 | RDS(ON) = 55 mΩ @ -4.5 V; lower ID rating (-4.1 A); SOT-23 package | Not pin-compatible; limited thermal capacity (RθJA = 210 °C/W); unsuitable for >1 W continuous loads | Select only for ultra-low-cost, low-power (<0.5 W) applications where board space is constrained |
Compared with DMG2305UVT-7 and SI2305DS-T1-E3, DMP2067LSS delivers the lowest RDS(ON) and best thermal performance in SO-8, making it optimal for thermally demanding, medium-power DC-DC and load-switching roles where efficiency and reliability are prioritized over minimal BOM cost.

FAQ
What is the maximum safe operating junction temperature for DMP2067LSS?
The absolute maximum junction temperature is +150°C, validated across the full operating range. Derating begins at TJ > 125°C per the Safe Operating Area (SOA) curve in Figure 12; sustained operation above 135°C requires active thermal monitoring or reduced current loading to maintain reliability.
Can DMP2067LSS be used in high-side switching configurations?
Yes - its P-channel architecture supports high-side switching when the source is connected to the positive rail and gate is driven below source potential. However, gate drive must provide sufficient negative swing (e.g., -4.5 V relative to source) and account for bootstrap or isolated driver requirements in AC-coupled topologies.
Is DMP2067LSS qualified for automotive applications?
No - DMP2067LSS is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., DMP2067LSSQ) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation; this part is intended for commercial and industrial use only.
What is the recommended PCB pad layout for optimal thermal performance?
Use the SO-8 thermal pad layout specified in Diodes' package outline document: 1-inch square 2 oz copper plane connected to the exposed drain pad via ≥4 thermal vias (0.3 mm diameter, filled or capped). This achieves RθJA = 75 °C/W and supports 1.67 W continuous power dissipation.
