Product details
Overview
DMPH2040UVTQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -20V VDSS, 38 mΩ RDS(ON) @ VGS = -4.5V, and -5.6A continuous drain current at TA = +25°C. It features AEC-Q101 qualification, 175°C maximum junction temperature, and TSOT26 packaging-designed for automotive DC-DC converters, motor control, and power management switches.
For engineers reviewing the DMPH2040UVTQ-13 datasheet, DMPH2040UVTQ-13 pinout, DMPH2040UVTQ-13 application, or DMPH2040UVTQ-13 equivalent, key selection criteria include gate threshold voltage (-0.6 to -1.5 V), low input capacitance (834 pF Ciss), thermal resistance (83 °C/W RθJA with enhanced layout), and PPAP-capable automotive qualification.
Technical Context
This device operates as a high-reliability, high-temperature P-channel switch in synchronous rectification and load-switching topologies. Its negative gate threshold enables direct logic-level drive from 3.3V/5V controllers when referenced to source, and its low RDS(ON) minimizes conduction loss in compact automotive power stages.
The TSOT26 package integrates an exposed drain pad for thermal performance, supporting 1.5 W power dissipation with optimized PCB copper. Dynamic parameters-including 8.6 nC total gate charge at VGS = -4.5V and 9.8 ns body diode reverse recovery time-enable efficient switching in 100–500 kHz DC-DC applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH2006LPSQ-13 | Lower RDS(ON) (2.8 mΩ @ -4.5V) but larger SO-8 package; higher Qg (29 nC) | Better for high-current (>10A) applications; unsuitable where TSOT26 footprint is mandatory | Select if thermal budget allows SO-8 and peak current exceeds 6A; avoid if board space or inductance-critical |
| DMG2302UK-7 | Same TSOT26 package but lower voltage rating (-20V same), higher RDS(ON) (60 mΩ @ -4.5V), not AEC-Q101 qualified | Acceptable for non-automotive industrial loads; lacks PPAP support and high-temp validation | Select only for cost-sensitive consumer-grade designs; reject for automotive or mission-critical systems |
Compared with DMTH2006LPSQ-13 and DMG2302UK-7, DMPH2040UVTQ-13 uniquely balances AEC-Q101 compliance, TSOT26 footprint, 38 mΩ conduction loss, and 8.6 nC gate charge-making it optimal for space-constrained, thermally demanding automotive power switches where qualification and reliability are mandatory.

FAQ
What is the maximum continuous drain current at 100°C ambient temperature?
The DMPH2040UVTQ-13 delivers -3.9 A continuous drain current at TA = +100°C with VGS = -4.5V, based on thermal derating from its 1.5 W power dissipation capability and 83 °C/W RθJA under enhanced PCB layout conditions.
Does this MOSFET require a gate driver IC for 3.3V microcontroller operation?
No. With a gate threshold voltage range of -0.6 V to -1.5 V, the DMPH2040UVTQ-13 fully enhances using a 3.3V GPIO pulled low to ground-no level shifter or dedicated gate driver is required for basic on/off switching at moderate frequencies.
How is thermal performance affected by PCB layout?
Thermal resistance drops from 125 °C/W (standard FR-4, single-sided) to 83 °C/W when using 2 oz copper with a 1-inch square thermal pad connected to the exposed drain. The TSOT26's drain-connected pins (1, 4, 6) must be soldered to this pad for rated performance.
Is the body diode suitable for synchronous rectification in buck converters?
Yes. The body diode exhibits 9.8 ns reverse recovery time and 2.7 nC QRR at -8.9A, enabling efficient synchronous rectification in 200–500 kHz buck converters-especially when paired with complementary N-channel control to minimize dead-time losses.
