Product details
Overview
DMP4047LFDEQ-13 from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET qualified to AEC-Q101, with RDS(ON) = 34 mΩ @ VGS = −10 V, ID = −6.5 A at TA = +25°C, and U-DFN2020-6 (Type E) package. It serves as a low-profile load switch in automotive battery management and power sequencing circuits.
For engineers reviewing the DMP4047LFDEQ-13 datasheet, DMP4047LFDEQ-13 pinout, DMP4047LFDEQ-13 application, or DMP4047LFDEQ-13 equivalent, key selection criteria include its −40 V VDSS, low gate threshold (−1.0 to −2.2 V), 100% production-tested UIS capability, and IATF 16949-manufactured traceability for automotive-grade reliability.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-side load switching configurations. Its gate threshold voltage range (−1.0 to −2.2 V) enables robust turn-on with standard 3.3 V or 5 V logic-level drive, while its 0.6 mm profile supports space-constrained PCB layouts.
The device integrates a body diode with VSD = −0.75 V @ IS = −3.9 A and tRR = 15.4 ns, supporting bidirectional current handling in battery protection and reverse-polarity protection circuits. Thermal resistance RθJA is 58 °C/W under 2 oz copper with thermal vias-critical for sustained 5.3 A operation at VGS = −4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | −40 V - Withstands up to 40 V reverse drain-source voltage without breakdown in automotive 12 V/24 V systems. |
| RDS(ON) @ VGS = −10 V | 34 mΩ max - Enables <0.23 W conduction loss at −6.5 A, reducing thermal stress in continuous load switching. |
| RDS(ON) @ VGS = −4.5 V | 50 mΩ max - Ensures reliable turn-on with 4.5 V logic supply, critical for microcontroller-driven power rails. |
| Qg @ VGS = −10 V | 24.9 nC - Determines gate drive energy requirement; compatible with standard MOSFET drivers in <1 MHz PWM applications. |
| tRR | 15.4 ns - Limits reverse recovery losses during commutation, supporting efficient synchronous rectification in DC-DC converters. |
| EAS | 26 mJ - Specifies single-pulse avalanche energy handling, enabling robustness against inductive load transients in motor control. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT4007LPSQ-13 | RDS(ON) = 28 mΩ @ −10 V, but larger U-DFN3030-8 package (3.0 × 3.0 mm); higher Qg (32 nC). | Requires more PCB area; better suited for higher-current (>8 A) applications where thermal margin is critical. | Select if higher current rating and lower RDS(ON) outweigh size constraints. |
| SI2301DDS-T1-GE3 | RDS(ON) = 115 mΩ @ −4.5 V; smaller SOT-23 package; no AEC-Q101 qualification. | Limited to non-automotive consumer/industrial use; unsuitable for PPAP-controlled production. | Choose only for cost-sensitive, non-automotive prototypes where qualification is not required. |
Compared with DMT4007LPSQ-13 and SI2301DDS-T1-GE3, the DMP4047LFDEQ-13 uniquely balances AEC-Q101 compliance, 4 mm² footprint, and sub-50 mΩ RDS(ON) at 4.5 V drive-making it optimal for space-constrained, safety-aware automotive power switches.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The DMP4047LFDEQ-13 supports −5.2 A continuous drain current at TA = +70°C with VGS = −10 V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the U-DFN2020-6 package under standard FR-4 board conditions with 2 oz copper and thermal vias.
Does this MOSFET require a gate resistor for stability?
A gate resistor (typically 10–100 Ω) is recommended to dampen ringing caused by gate-drain capacitance (Crss = 76 pF) and PCB trace inductance. The datasheet's switching time test condition (RG = 1 Ω) assumes minimal external resistance; practical designs use higher values to balance EMI and switching speed.
Can the DMP4047LFDEQ-13 be used in synchronous rectification?
No-it is a P-channel MOSFET optimized for high-side switching, not synchronous rectification. Its body diode forward voltage (VSD = −0.75 V) and reverse recovery time (tRR = 15.4 ns) are not optimized for freewheeling in buck converters; N-channel devices with dedicated synchronous controllers are preferred for that function.
Is the exposed thermal pad electrically isolated?
Yes-the exposed pad (pins 4–6) is internally connected to the drain terminal and must be soldered to a PCB copper pour tied to the drain net. It is not electrically isolated and serves both thermal dissipation and mechanical anchoring functions per the U-DFN2020-6 Type E mechanical drawing.
