Product details
Overview
DMP2040UND-13 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in a PowerDI®3333-8 (UXB) package, rated for -20V VDSS, 36mΩ RDS(ON) @ VGS = -4.5V, and -5.3A continuous drain current at TA = +25°C. It serves as a compact, low-loss synchronous rectifier or load switch in space-constrained DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMP2040UND-13 datasheet, DMP2040UND-13 pinout, DMP2040UND-13 application, or DMP2040UND-13 equivalent, key selection criteria include gate threshold voltage (-0.6 to -1.5V), low input capacitance (834pF Ciss), fast switching (14.6ns tD(ON)), thermal resistance (88°C/W RθJA with enhanced layout), and dual-channel integration for balanced current sharing.
Technical Context
This dual P-channel MOSFET integrates two matched, independently controllable transistors in a single exposed-drain thermally optimized package. Its low VGS(TH) enables direct logic-level drive from 3.3V or 5V controllers without level-shifting, while symmetric RDS(ON) tracking across channels supports parallel operation in high-side switching or bidirectional power path control.
The device features low gate charge (9.6nC Qg @ VGS = -4.5V) and minimal reverse transfer capacitance (105pF Crss), reducing Miller-induced turn-off delay and improving efficiency in high-frequency (>1MHz) buck or boost topologies. Body diode recovery (9.8ns tRR, 2.7nC QRR) is optimized for synchronous rectification with reduced shoot-through risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20V - Maximum blocking voltage for high-side switch or reverse-polarity protection in 12V/15V systems. |
| RDS(ON) | 36mΩ @ VGS = -4.5V - Enables <180mW conduction loss at 7.5A per channel in compact layouts. |
| ID (continuous) | -5.3A @ TA = +25°C - Supports >10W power handling per channel with standard FR-4 PCB thermal bias. |
| Ciss | 834pF - Reduces gate drive power requirement and improves switching efficiency above 500kHz. |
| tD(ON) | 14.6ns - Minimizes dead-time overhead in synchronous buck converters, preserving duty cycle fidelity. |
| RθJA | 88°C/W - Achievable with 2oz copper and 1-inch² thermal pad; enables 1.4W dissipation at ambient ≤70°C. |
| VGS(TH) | -0.6 to -1.5V - Ensures reliable turn-on with 3.3V GPIO or low-voltage PMIC outputs without external bias. |

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 |
|---|---|---|---|
| DMG1012T-7 | Single-channel, SOT-563, 45mΩ @ -4.5V, lower ID (-2.8A) | Requires two devices for dual functionality; larger total footprint and higher gate drive count. | Preferred only when board space allows discrete placement and thermal separation is critical. |
| SI3993DV-T1-GE3 | Dual P-channel, TSOP-6, 50mΩ @ -4.5V, higher RθJA (120°C/W) | Limited to ≤3.5A/channel in same PCB layout; unsuitable for >1MHz switching due to 1.2nC higher Qg. | Select when legacy TSOP-6 compatibility is required and thermal budget permits derating. |

FAQ
What is the maximum safe operating temperature for DMP2040UND-13?
The junction temperature must not exceed +150°C under steady-state conditions. With RθJA = 88°C/W and ambient ≤70°C, the device supports up to 1.4W continuous power dissipation using recommended 2oz copper thermal bias. Derating is required above 70°C ambient per Figure 5 and Figure 7 in DS42189 Rev. 3-2.
Can DMP2040UND-13 be used in linear regulator applications?
No-it is optimized for switching operation only. Its RDS(ON) variation with temperature (Figure 6) and lack of SOA curves beyond pulsed operation indicate it is not characterized for linear-mode biasing. Use dedicated LDOs or bipolar pass transistors for regulated linear supplies.
Is the PowerDI3333-8 package compatible with standard reflow profiles?
Yes. The package is qualified for lead-free reflow per J-STD-020, with peak temperature ≤260°C and time above liquidus ≤60 seconds. Moisture sensitivity level 1 eliminates bake requirements; standard SnPb or SAC305 profiles apply without modification.
Does DMP2040UND-13 meet automotive qualification standards?
As shipped, DMP2040UND-13 is not AEC-Q101 qualified. Diodes Incorporated offers automotive-grade variants (e.g., DMP2040UNDQ-13) with PPAP documentation, IATF 16949 manufacturing, and extended temperature testing-contact Diodes' automotive team for qualified part numbers and change control support.
