Product details
Overview
DMP31D1UVTQ from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in TSOT26 package, rated for -30V VDSS, 1000mΩ RDS(ON) @ VGS = -4.5V, and -0.76A continuous drain current at +25°C. It serves as a compact, AEC-Q101-qualified load switch or synchronous rectifier in space-constrained DC-DC converters and backlighting circuits.
For engineers reviewing the DMP31D1UVTQ datasheet, DMP31D1UVTQ pinout, DMP31D1UVTQ application, or DMP31D1UVTQ equivalent, this page delivers verified electrical parameters, validated TSOT26 terminal mapping, automotive-grade qualification status, and real-world switching performance data including Ciss = 54pF and tF = 20ns.
Technical Context
This dual MOSFET integrates two independent P-channel devices sharing no internal connection-each with discrete source, gate, and drain terminals. Its low RDS(ON) at -4.5V gate drive enables efficient operation in 3.3V/5V logic-controlled power rails, while its 1.0nC total gate charge supports fast turn-on (tD(ON) = 3.8ns) and controlled turn-off (tD(OFF) = 45ns).
The device's thermal resistance of RθJA = 243°C/W (minimum pad layout) and 143°C/W (1-inch copper plate) reflects its dependence on PCB layout for power dissipation. Junction temperature range spans -55°C to +150°C, supporting operation in automotive under-hood environments where ambient temperatures exceed 105°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30V - Maximum drain-source blocking voltage before avalanche conduction begins. |
| RDS(ON) | 1000mΩ @ VGS = -4.5V - On-resistance determines I²R conduction loss in high-side switching applications. |
| ID | -0.76A @ TA = +25°C - Continuous current capability under standard FR-4 board conditions with minimum copper. |
| Ciss | 54pF @ VDS = -15V - Input capacitance governs gate drive energy requirement and switching speed limitation. |
| Qg | 1.0nC @ VGS = -4.5V - Total gate charge defines driver strength needed for full enhancement in <100ns transitions. |
| tF | 20ns - Fall time sets minimum achievable PWM frequency before overlap losses dominate in synchronous buck stages. |
| TJ Range | -55°C to +150°C - Validated operating junction temperature window for automotive AEC-Q101 compliance. |
Pinout & Package
Package: TSOT26 - 6-pin ultra-thin surface-mount package (2.9mm × 1.6mm × 0.6mm), RoHS-compliant, halogen-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D1) | Drain of Q1 | Primary current-carrying terminal for first P-channel MOSFET; connected to high-side rail or load return path. |
| 2 (S1) | Source of Q1 | Reference node for Q1 gate drive; tied to output or ground depending on high-side/low-side configuration. |
| 3 (G1) | Gate of Q1 | Control input for Q1; requires negative VGS relative to S1 to enhance channel. |
| 4 (D2) | Drain of Q2 | Independent drain terminal for second P-channel MOSFET; electrically isolated from Q1. |
| 5 (S2) | Source of Q2 | Separate reference node for Q2; enables dual independent switching paths in compact footprint. |
| 6 (G2) | Gate of Q2 | Independent control input; allows asynchronous or synchronized operation of both channels. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3026LSD-13 | RDS(ON) = 85mΩ @ -4.5V (single-channel SO-8); higher current rating (-4.2A) but larger footprint. | Not pin-compatible; requires PCB redesign; better suited for higher-power single-switch applications. | Select when >1A load current or lower RDS(ON) dominates over board space constraints. |
| AOB410L | Dual P-channel in TSOP-6; RDS(ON) = 1200mΩ @ -4.5V; higher Qg (1.8nC); non-AEC-Q101 rated. | Lacks automotive qualification; suitable only for commercial-grade consumer electronics. | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not required. |
Compared with DMN3026LSD-13 and AOB410L, DMP31D1UVTQ uniquely balances AEC-Q101 compliance, TSOT26 miniaturization, and sub-1Ω RDS(ON) - making it the only option among the three qualified for automotive cabin electronics with strict space and reliability requirements.

FAQ
Is DMP31D1UVTQ suitable for high-side switching with 3.3V GPIO control?
Yes. With VGS(TH) ranging from -0.5V to -1.1V and RDS(ON) = 1000mΩ at VGS = -4.5V, it fully enhances using a 3.3V microcontroller driving the source at 3.3V and gate at 0V - achieving effective VGS ≈ -3.3V. Verified operation confirmed down to VGS = -2.5V (RDS(ON) = 1500mΩ).
What is the maximum safe pulsed drain current for DMP31D1UVTQ?
The datasheet specifies IDM = -1.9A for 10μs pulses at 1% duty cycle. This limit is constrained by peak junction temperature rise and SOA curves in Figure 12. For repetitive 100μs pulses, derating to ≤ -1.2A is recommended to maintain TJ < 150°C under typical PCB thermal conditions.
Does DMP31D1UVTQ include integrated ESD protection?
No. The device has no built-in ESD protection diodes. Its gate oxide is rated for ±8V VGSS, and external TVS or RC filtering is required on gate traces in environments with >2kV HBM risk. Layout best practices include short gate routing and local 100Ω series resistors.
Can DMP31D1UVTQ replace a single P-channel MOSFET in existing designs?
Yes - each channel operates independently. To use only one channel, leave the unused gate floating (not recommended) or tie it to its respective source. For robustness, connect unused G2 to S2 and unused D2/S2 to system ground or leave unconnected per layout isolation requirements.
