Product details
Overview
DMG3401LSNQ-13 from Diodes Incorporated is a 30V P-channel enhancement-mode MOSFET in SC59 package, rated for -3.7A continuous drain current at VGS = -10V, with RDS(on) = 50 mΩ, AEC-Q101 qualified, and optimized for automotive power management. It serves as a high-efficiency load switch in low-voltage DC-DC converters, backlight dimming circuits, and motor control stages.
For engineers reviewing the DMG3401LSNQ-13 datasheet, DMG3401LSNQ-13 pinout, DMG3401LSNQ-13 application, or DMG3401LSNQ-13 equivalent, key selection criteria include verified RDS(on) at -4.5V (-60 mΩ), thermal resistance (RθJA = 105 °C/W on 2oz copper), AEC-Q101 qualification status, and SC59 footprint compatibility with space-constrained PCB layouts.
Technical Context
This MOSFET operates in enhancement mode with a gate threshold voltage (VGS(th)) of -0.5 to -1.3 V, enabling reliable turn-on from standard 3.3V/5V logic-level controllers. Its low input capacitance (Ciss = 1326 pF) and fast switching (tD(on) = 8 ns, tf = 38 ns) support high-frequency PWM operation in compact power stages.
The device integrates a body diode with VSD = -0.8 to -1.0 V at -1A, supporting synchronous rectification and freewheeling in buck and H-bridge topologies. Thermal design is enabled by its 36 °C/W junction-to-case resistance and IATF16949-certified manufacturing for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum blocking voltage for 12V automotive rail and 24V industrial supply interfaces |
| RDS(on) @ -10V | 50 mΩ - Enables ≤185 mW conduction loss at -3.7A, critical for thermally constrained modules |
| ID (cont, 25°C) | -3.7 A - Sustains full-load current in small-signal motor drivers and LED backlight arrays |
| Ciss | 1326 pF - Limits gate drive power and enables use with low-current microcontroller GPIOs |
| Qg @ -4.5V | 11.6 nC - Determines minimum gate driver slew rate for <50 ns rise/fall in 500 kHz switching |
| RθJA | 105 °C/W - Requires ≥1-in² 2oz copper pad for 1.2 W dissipation at TA = 70°C ambient |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive under-hood and infotainment applications |

Applications
| Automotive Interior Lighting | USB-C Power Delivery Switch |
|---|---|
Use Scenario: Dimmable LED backlight for instrument clusters and center displays using PWM at 1–5 kHz. IC Role / Device Role / Timing Role: Low-side load switch controlling cathode-side current with fast turn-off to prevent ghosting during frame updates.

IC Role / Device Role / Timing Role: Standby-mode disconnect switch reducing quiescent current to <1 µA when sensors are inactive. Use Value: Gate leakage <±100 nA and zero-gate-voltage drain current <−1.0 µA ensure <10 µW standby loss per channel. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG3401L-7 | Same die, SC59 package, but non-automotive grade (no AEC-Q101, no PPAP) | Lacks change control and automotive qualification documentation | Select only for cost-sensitive consumer or industrial prototypes where automotive compliance is not required |
| Si2301BDS-T1-GE3 | RDS(on) = 90 mΩ @ -4.5V; higher Ciss (1500 pF); same SC59 footprint | Lower efficiency at 3.3V drive; unsuitable for high-frequency (>300 kHz) or high-current (>2.5A) loads | Acceptable for low-duty-cycle, low-power indicator loads where thermal margin is ample |
Compared with DMG3401LSNQ-13, DMG3401L-7 offers identical electrical performance but lacks automotive traceability, while Si2301BDS-T1-GE3 trades higher conduction loss and slower switching for broader distributor availability-making DMG3401LSNQ-13 optimal for production automotive and high-reliability industrial power switches.

FAQ
What is the maximum safe operating temperature for DMG3401LSNQ-13?
The device supports junction temperatures from −55°C to +150°C. With RθJA = 105°C/W on a 2oz copper board, it sustains 1.2 W dissipation at 70°C ambient. Derating is required above 70°C ambient; full-rated current is only guaranteed below 25°C ambient unless heatsinking is added.
Can DMG3401LSNQ-13 be driven directly by a 3.3V microcontroller GPIO?
Yes - its VGS(th) range (−0.5 V to −1.3 V) and RDS(on) = 60 mΩ at VGS = −4.5 V allow functional switching at 3.3V logic levels, though conduction loss increases to ~110 mΩ. For minimal loss, use a dedicated gate driver or level shifter to achieve −4.5 V or lower.
Is the body diode suitable for reverse-current protection in USB-C applications?
No - the intrinsic body diode conducts in the forward direction (source-to-drain), so it cannot block reverse current. For USB-C VBUS reverse polarity protection, DMG3401LSNQ-13 must be used in high-side configuration with external control logic to prevent backfeed; it does not provide automatic reverse-blocking functionality.
Does DMG3401LSNQ-13 require special PCB layout considerations for thermal performance?
Yes - the SC59 package relies on the source pad for heat transfer. A minimum 1-inch² copper area (2oz) connected to the source terminal via multiple thermal vias is required to achieve the rated 1.2 W power dissipation. Avoid narrow traces or isolated pads, which raise junction temperature beyond safe limits.
