Product details
Overview
DMP2040USD-13 from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in SO-8 package, rated for -20V VDSS, 33 mΩ RDS(ON) @ VGS = -4.5V, and -6.5A 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 DMP2040USD-13 datasheet, DMP2040USD-13 pinout, DMP2040USD-13 application, or DMP2040USD-13 equivalent, key selection criteria include its dual-channel P-channel topology, low gate threshold (-0.6 to -1.5 V), fast switching (tF = 14.6 ns), thermal resistance (RθJA = 76 °C/W with enhanced layout), and SO-8 lead-free RoHS-compliant construction.
Technical Context
This dual MOSFET integrates two matched P-channel devices sharing a common source configuration in a single SO-8 footprint, enabling high-side switching without external level-shifting circuitry. Its low RDS(ON) at -2.5V gate drive supports efficient operation in battery-powered systems where gate voltage headroom is limited.
The device features low input capacitance (Ciss = 834 pF) and fast turn-off delay (tD(OFF) = 28.1 ns), optimized for synchronous buck converter topologies operating up to 1 MHz. Body diode recovery (tRR = 9.8 ns, QRR = 2.7 nC) minimizes shoot-through losses during dead-time transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -20 V - Maximum drain-source blocking voltage for 12V rail applications with margin |
| RDS(ON) | 33 mΩ @ VGS = -4.5V - Enables <100 mW conduction loss at 6.5A in compact layouts |
| ID (continuous) | -6.5 A @ TA = +25°C - Supports mid-power load switching without forced cooling |
| VGS(TH) | -0.6 to -1.5 V - Ensures reliable turn-on from 3.3V logic or low-voltage microcontroller outputs |
| Ciss | 834 pF - Reduces gate drive power and enables efficient high-frequency PWM control |
| tF | 14.6 ns - Limits overlap time in synchronous rectification, reducing cross-conduction risk |
| RθJA | 76 °C/W (enhanced layout) - Allows 1.6 W dissipation with ≤122°C junction rise above ambient |
Pinout & Package

Applications
| LED Backlight Control | USB-C Power Delivery Switch |
|---|---|
|
Use Scenario: Driving parallel white LED strings in portable displays using PWM dimming and overvoltage protection. IC Role / Device Role: Dual-channel high-side current switch controlling LED anode voltage with independent enable per string. Use Value: Low RDS(ON) minimizes forward voltage drop across each channel, preserving headroom for LED forward voltage and improving luminous efficiency by >3% vs. discrete alternatives. |

|
Use Scenario: Synchronous rectification in isolated 24V-to-5V flyback or active-clamp forward converters. IC Role / Device Role: Secondary-side dual P-MOSFET replacing Schottky diodes to reduce conduction losses and improve thermal performance. Use Value: 33 mΩ RDS(ON) cuts secondary-side conduction loss by 65% versus 40V/3A Schottky, enabling >92% full-load efficiency at 100 kHz switching frequency. |
Use Scenario: Controlled power-up sequencing of display, audio, and MCU subsystems in automotive head units. IC Role / Device Role: Dual independent load switches managing separate 5V and 3.3V rails with programmable enable timing. Use Value: Independent gate inputs allow precise staggered turn-on (via RC delays), preventing inrush current peaks exceeding 5A and avoiding brown-out on shared 12V supply. |
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 |
|---|---|---|---|
| DMC2040UDM-7 | Same SO-8 package, but RDS(ON) = 42 mΩ @ -4.5V; higher gate charge (Qg = 11.5 nC) | Slightly lower efficiency in high-current DC-DC; better suited for cost-sensitive, lower-frequency (<300 kHz) designs | Select when BOM cost priority outweighs 0.5% efficiency gain and thermal margin is adequate |
| SI3483DV-T1-GE3 | SO-8 dual P-MOSFET with RDS(ON) = 30 mΩ @ -4.5V but VDSS = -12V only; no 20V rating | Not suitable for 15–20V input rails; limited to 12V systems with tighter voltage margins | Choose only for 12V-only applications requiring marginal RDS(ON) improvement and accepting reduced voltage safety margin |
Compared with DMC2040UDM-7 and SI3483DV-T1-GE3, the DMP2040USD-13 uniquely balances -20V rating, 33 mΩ on-resistance, and 8.6 nC gate charge-making it optimal for 12–20V industrial and automotive DC-DC converters where voltage margin, efficiency, and thermal density are jointly constrained.

FAQ
What is the maximum safe operating temperature for DMP2040USD-13?
The DMP2040USD-13 has a specified junction temperature range of -55°C to +150°C. With RθJA = 76 °C/W (enhanced layout), sustained 1.6 W power dissipation raises junction temperature by 122°C above ambient. Therefore, maximum safe ambient temperature is +28°C for continuous 1.6 W operation; derating is required above that.
Can DMP2040USD-13 be used in a back-to-back configuration for AC blocking?
Yes-the dual P-channel structure allows back-to-back connection (S1–D2 and S2–D1 tied) to block bidirectional current flow. Each channel's body diode is oriented opposite to the other, enabling true AC isolation up to -20V peak. Gate drive must be referenced to respective sources, not ground.
Is the exposed pad electrically isolated or internally connected?
The exposed pad (pins 7 and 8) is internally connected to both drains (D1 and D2). It is not isolated and must be soldered to a PCB ground or power plane serving as the drain return path. Failure to connect it thermally and electrically degrades RθJC and risks thermal runaway under load.
Does DMP2040USD-13 support logic-level gate drive from 3.3V microcontrollers?
Yes-its gate threshold voltage range (-0.6 V to -1.5 V) ensures full enhancement with 3.3V logic outputs driving the gate negative relative to source. At VGS = -3.3V, RDS(ON) is ~38 mΩ (interpolated from datasheet curves), delivering usable performance without level-shifting circuitry.
