Product details
Overview
DMP31D7LDWQ-13 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SOT363 package, rated for -30V VDSS, 0.9Ω RDS(ON) @ VGS = -10V, and -0.55A continuous drain current at +25°C - designed for compact, high-efficiency power management in space-constrained automotive and industrial DC-DC converters.
For engineers reviewing the DMP31D7LDWQ-13 datasheet, DMP31D7LDWQ-13 pinout, DMP31D7LDWQ-13 application, or DMP31D7LDWQ-13 equivalent, key selection criteria include gate threshold voltage (-1 to -2.6V), ESD-protected gate, AEC-Q101 qualification, and dual-channel thermal coupling in a 6-pin leadless package.
Technical Context
This dual P-MOSFET integrates two matched enhancement-mode channels sharing a common source configuration (S1/S2 tied internally per device layout), with independent gate control enabling synchronous buck high-side switching or load-switching redundancy. Each channel supports ±20V gate drive and exhibits low input capacitance (19pF Ciss) and fast switching (tr = 74ns).
Thermal performance is defined by RθJA = 301°C/W (with 1-in² copper) and 433°C/W (standard FR-4), supporting operation from -55°C to +150°C junction temperature. The device's gate protection diode and AEC-Q101 qualification confirm suitability for automotive power rails requiring PPAP-capable, IATF 16949-manufactured components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - maximum blocking voltage before avalanche conduction in each channel |
| RDS(ON) | 0.9Ω @ VGS = -10V - on-resistance determines conduction loss in 5V/3.3V logic-driven high-side switches |
| ID (max) | -0.55A @ TA = +25°C - continuous current capability limited by package thermal resistance and copper area |
| Ciss | 19pF - low input capacitance enables fast turn-on with minimal gate drive energy |
| VGS(TH) | -1 to -2.6V - negative threshold ensures reliable turn-on with standard 3.3V microcontroller GPIO |
| Qg | 0.8nC @ VGS = -10V - total gate charge defines switching transition time and driver sizing requirement |
| TJ range | -55°C to +150°C - extended temperature rating validated for under-hood automotive environments |
Pinout & Package
Package: SOT363 - 6-pin, surface-mount, lead-free molded plastic package with matte tin finish; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.006g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| G1 | Gate of Q1 | Independent control input for first P-MOSFET channel |
| S1 | Source of Q1 | Common source node for Q1; electrically isolated from S2 unless externally connected |
| D1 | Drain of Q1 | Power output node for Q1; routed separately to avoid cross-talk with Q2 |
| G2 | Gate of Q2 | Independent control input for second P-MOSFET channel |
| S2 | Source of Q2 | Common source node for Q2; not internally tied to S1 |
| D2 | Drain of Q2 | Power output node for Q2; supports dual-load or redundant switching topologies |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power systems including body control modules and infotainment power rails |
| ESD-protected gate | Withstands ≥2kV HBM per JEDEC JS-001, eliminating need for external gate protection in most layouts |
| Low RDS(ON) at -4.5V | 1.7Ω enables efficient operation directly from 5V supply without level-shifting circuitry |
| Halogen- and antimony-free | Meets "Green" definition: Br+Cl <1500ppm, Sb <1000ppm - compliant with automotive environmental directives |
| Fast switching speed | td(on) = 30ns, tr = 74ns - reduces switching losses in 500kHz–1MHz DC-DC applications |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | Single-channel, 30V, 0.045Ω RDS(ON) @ -10V, SO-8 package | Higher current capacity but larger footprint and no dual-channel integration | Select when higher current per channel (>2A) is required and board space allows SO-8 |
| SI3483DV-T1-GE3 | Dual P-channel, 30V, 1.2Ω RDS(ON) @ -4.5V, SOT-363, no AEC-Q101 | Lacks automotive qualification and has higher RDS(ON) at low gate drive | Acceptable for cost-sensitive industrial use where AEC-Q101 is not mandated |
Compared with DMN3026LSD-13 and SI3483DV-T1-GE3, DMP31D7LDWQ-13 uniquely balances dual-channel integration, AEC-Q101 compliance, and low-voltage gate drive in SOT363 - making it optimal for space-constrained automotive power nodes requiring functional redundancy.

FAQ
Is DMP31D7LDWQ-13 pin-compatible with other SOT363 dual MOSFETs?
No - DMP31D7LDWQ-13 uses a non-standard pinout: G1-S1-D1-G2-S2-D2 (top view). Unlike common SOT363 dual N-MOSFETs (e.g., 2N7002DW), its dual P-channel configuration places gates adjacent to sources, requiring careful PCB layout verification against the official Diodes top-view diagram.
What is the maximum pulsed drain current for DMP31D7LDWQ-13?
The absolute maximum pulsed drain current is -2.4A for 10µs pulses at 1% duty cycle, as specified in the Absolute Maximum Ratings table. This value assumes ideal thermal conditions and is limited by bond wire integrity, not silicon area - sustained operation above -0.55A requires derating per RθJA and ambient temperature.
Does DMP31D7LDWQ-13 include integrated body diodes?
Yes - each P-channel MOSFET includes an intrinsic body diode oriented from source to drain (S→D), with typical forward voltage of -0.8V to -1.2V at -0.23A. These diodes support freewheeling in inductive loads and reverse-polarity protection, but are not rated for continuous conduction beyond the specified maximum body diode current of -0.38A.
Can DMP31D7LDWQ-13 be used in linear regulation mode?
No - the device is characterized and qualified only for switching operation. Its RDS(ON) variation with temperature (±20% from -55°C to +150°C) and lack of Safe Operating Area (SOA) curves for linear mode make it unsuitable for pass-element applications; dedicated LDOs or linear regulators should be used instead.
