Product details
Overview
DMP2012SN-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SC59 package, rated for -20V VDSS, 0.3Ω RDS(ON) at VGS = -4.5V, and -0.9A continuous drain current at +25°C - optimized for high-efficiency DC-DC converters and compact power management circuits.
For engineers reviewing the DMP2012SN-7 datasheet, DMP2012SN-7 pinout, DMP2012SN-7 application, or DMP2012SN-7 equivalent, key selection criteria include gate threshold voltage (-0.5 to -1.2V), low input capacitance (178.5 pF), fast switching (10.4 ns tD(ON)), ESD-protected gate, and thermal resistance of 250°C/W in FR-4 PCB mounting.
Technical Context
This MOSFET operates as a low-side load switch or synchronous rectifier in buck converters, leveraging its low RDS(ON) and fast turn-off delay (175 ns) to minimize conduction and switching losses. Its -1.2V typical VGS(TH) enables direct drive from 3.3V logic with margin.
The integrated body diode (VSD = -0.8 to -1.1V at -0.7A) supports freewheeling paths in step-down topologies, while Ciss/Coss ratio (178.5 pF / 26.3 pF) supports stable gate drive design with minimal Miller effect.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - maximum blocking voltage for 3.3V/5V rail applications with safety margin |
| RDS(ON) | 0.3Ω @ VGS = -4.5V - enables <150 mW conduction loss at 0.4A load |
| ID (continuous) | -0.9A @ TA = +25°C - suitable for sub-1W power stages on standard FR-4 PCB |
| VGS(TH) | -0.5 to -1.2V - ensures reliable turn-on with 2.5–3.3V control signals |
| Ciss | 178.5 pF - determines gate drive strength requirement (~1.8 mA avg. for 1 MHz switching) |
| tD(OFF) | 175 ns - limits minimum off-time in high-frequency (>2 MHz) PWM designs |
| RθJA | 250°C/W - requires thermal relief pads or airflow for >300 mW sustained dissipation |
Pinout & Package
Package: SC59 - surface-mount, 3-pin plastic package (0.014 g), JEDEC-compliant, moisture sensitivity level 1, matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | High-side connection to input rail or inductive node | Carries full load current; ties to PCB thermal pad for heat dissipation |
| Gate (G) | Control terminal for channel modulation | ESD-protected; requires <1.8 mA drive for 1 MHz switching due to 178.5 pF Ciss |
| Source (S) | Reference node for gate drive and current return path | Connected to ground or output rail; forms cathode of integrated body diode |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) | 0.3Ω @ -4.5V enables >90% efficiency in 3.3V-input buck converters at 0.4A |
| Low VGS(TH) | -1.2V max ensures full enhancement with 2.5V GPIO, eliminating level-shifter need |
| Fast switching | 10.4 ns tD(ON) and 64 ns tf support >2 MHz operation with minimal dead-time loss |
| ESD-protected gate | HBM rating ≥2 kV per JESD22-A114 - reduces handling risk during SMT assembly |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant (≤900 ppm Br/Cl, ≤1000 ppm Sb) |
Applications
| DC-DC Buck Converter | USB Power Switch |
|---|---|

Use Value: IDSS ≤ -10 µA at -20V ensures <1 µA system standby current, extending battery life beyond 1 year. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2012LFG-7 | Same SC59 package; lower RDS(ON) (0.18Ω @ -4.5V) but higher Ciss (220 pF); VGS(TH) -0.7 to -1.3V | Better conduction loss at high current; slower switching limits >1.5 MHz use | Prefer for efficiency-critical, lower-frequency (<1 MHz) power rails |
| AO3401 | SC70-3 package; RDS(ON) 0.085Ω @ -4.5V; higher ID (4.2A); no specified ESD rating | Higher current capacity but larger footprint; lacks gate ESD protection per datasheet | Prefer when board space allows SC70 and robustness against handling ESD is managed externally |
Compared with DMN2012LFG-7 and AO3401, DMP2012SN-7 offers balanced trade-offs: moderate RDS(ON), verified ESD protection, and proven thermal performance in SC59 - making it optimal for cost-sensitive, space-constrained 3.3V/5V power switches where reliability and manufacturability are prioritized over peak efficiency or current rating.

FAQ
What is the maximum safe operating junction temperature for DMP2012SN-7?
The DMP2012SN-7 has an absolute maximum junction temperature of +150°C per its datasheet. Derating begins at +25°C ambient, with thermal resistance RθJA = 250°C/W on FR-4 PCB. At 300 mW dissipation, junction temperature rises ~75°C above ambient - so operation up to +75°C ambient stays within safe limits without heatsinking.
Can DMP2012SN-7 be used as a high-side switch with 5V gate drive?
No - DMP2012SN-7 is a P-channel MOSFET requiring negative gate-to-source voltage for turn-on. With source tied to 5V, a 0V gate yields VGS = -5V, which fully enhances the device. Direct 5V logic cannot drive it high-side without an inverting level shifter or charge pump to pull gate below source.
Does DMP2012SN-7 have a built-in body diode, and what is its forward voltage?
Yes - it integrates a parasitic body diode between source and drain (anode at drain, cathode at source). At -0.7A and TA = +25°C, VSD is -0.8 to -1.1V. This diode enables freewheeling in buck converters but introduces reverse recovery loss if used in synchronous rectification without careful timing control.
Is DMP2012SN-7 qualified for automotive applications under AEC-Q101?
No - the official Diodes datasheet states that DMP2012SN-7 is a standard-grade part. Automotive-qualified equivalents (e.g., DMP2012SNQ-7) exist but require explicit AEC-Q101 qualification, PPAP documentation, and IATF 16949 manufacturing - none of which apply to the -7 suffix variant.
