Product details
Overview
DMN3732UVTQ from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in TSOT26 package, rated for 30V VDSS, 460mΩ RDS(ON) @ 4.5V VGS, and 1.1A continuous drain current at +25°C. It delivers low on-resistance with fast switching for compact DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMN3732UVTQ datasheet, DMN3732UVTQ pinout, DMN3732UVTQ application, or DMN3732UVTQ equivalent, key selection criteria include dual-channel RDS(ON) matching at low gate drive (2.5V–4.5V), AEC-Q101 qualification for automotive power management, and thermal resistance of 150°C/W under enhanced PCB layout.
Technical Context
This dual MOSFET integrates two matched N-channel devices sharing no internal connection-each channel operates independently with separate gate, source, and drain terminals. Its 0.9nC total gate charge and 4.6pF reverse transfer capacitance enable efficient 1MHz-class switching in synchronous buck stages.
The device uses trench-gate process technology to achieve 310mΩ typical RDS(ON) at 4.5V VGS while maintaining 0.72A body diode forward current capability and ±8V gate-source voltage rating-critical for robust gate driving in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - supports 24V rail systems with 25% margin against transients |
| RDS(ON) @ 4.5V | 460mΩ max - enables <1.2W conduction loss at 1.1A in space-constrained layouts |
| ID (TA=25°C) | 1.1A - sufficient for low-power load switches and auxiliary DC-DC phases |
| Ciss | 40.8pF - reduces gate drive power requirement in high-frequency PWM control |
| Qg | 0.9nC - allows fast turn-on with minimal gate driver current (e.g., <1mA avg at 1MHz) |
| TJ Range | −55°C to +150°C - validated for under-hood automotive operation per AEC-Q101 |
| PD (enhanced layout) | 0.8W - achievable with 1-inch² copper pour, enabling 0.5W continuous dissipation in standard FR-4 |
Pinout & Package
Package: TSOT26 - ultra-thin (1.0mm max height), 6-pin surface-mount package with exposed thermal pad (not electrically connected), RoHS-compliant matte tin finish over copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D1) | Drain of Q1 | High-side or low-side switch node for first MOSFET channel |
| 2 (S1) | Source of Q1 | Return path for Q1; tied to ground or switched node depending on topology |
| 3 (G1) | Gate of Q1 | Control input requiring ≤0.9nC charge for full enhancement |
| 4 (D2) | Drain of Q2 | Independent drain terminal for second channel-no internal coupling to Q1 |
| 5 (S2) | Source of Q2 | Separate return path for Q2; enables floating or common-source configurations |
| 6 (G2) | Gate of Q2 | Isolated control input; allows independent or paralleled gate drive |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 2.5V VGS | 560mΩ max - enables direct drive from 3.3V microcontrollers without level-shifting |
| Fast switching speed | tr = 15.9ns, tf = 20.0ns - minimizes transition losses in 500kHz–1MHz DC-DC designs |
| AEC-Q101 qualified | Validated for automotive temperature cycling, HTRB, and ESD per JESD22-A114 - supports PPAP submission |
| Green compound packaging | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - meets automotive OEM environmental requirements |
| Low leakage | IDSS ≤ 1µA at 30V - preserves battery life in always-on power rails |
Applications
| Automotive Interior Lighting | Portable Device Power Management |
|---|---|

IC Role / Device Role / Timing Role: Single-channel used as main switch; second channel unused or paralleled for higher current handling. Use Value: 30V VDSS provides headroom above 24V boost output, while 150°C/W RθJA ensures stable operation at 70°C ambient with minimal heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3029LSD-13 | 30V, 29mΩ @ 10V (single-channel SO-8); higher RDS(ON) at 4.5V not specified | Requires larger footprint; lacks dual-channel integration and AEC-Q101 certification | Select when higher current (>3A) and board area allow SO-8; avoid for space-constrained automotive modules |
| AOB410L | 30V, 4.1mΩ @ 10V (dual-channel TSSOP-8); no 2.5V/4.5V RDS(ON) data published | Higher gate charge (12nC), unsuitable for low-voltage MCU drive | Prefer only for high-efficiency, high-current (>2A) industrial supplies where gate drive voltage ≥10V is available |
Compared with DMN3732UVTQ, DMN3029LSD-13 offers lower on-resistance but sacrifices integration, automotive qualification, and low-VGS drive capability; AOB410L provides superior conduction performance but demands higher gate drive energy and lacks verified low-voltage switching behavior.

FAQ
What is the maximum safe operating junction temperature for DMN3732UVTQ?
The absolute maximum junction temperature is +150°C, validated per AEC-Q101 stress testing. Continuous operation at this limit requires thermal design ensuring steady-state TJ ≤ 150°C-achievable with 0.8W power dissipation on a 1-inch² copper pour (RθJA = 150°C/W). Derating is required above +125°C ambient.
Can DMN3732UVTQ be used in parallel configurations across both channels?
Yes-both channels are electrically isolated and parametrically matched (RDS(ON) variation ≤15% typical at 4.5V). Parallel use doubles current capacity to 2.2A, provided gate drive impedance is balanced and PCB layout symmetry minimizes current imbalance due to parasitic inductance.
Does DMN3732UVTQ include integrated ESD protection on gate terminals?
No-gate terminals have ±8V VGSS rating but no on-chip ESD clamp. External 10kΩ series gate resistors and 12V TVS diodes are recommended for automotive environments per ISO 10605, especially when routed near connectors or long traces.
Is the TSOT26 package's exposed pad internally connected to any terminal?
No-the TSOT26 package has an exposed thermal pad that is not electrically connected to any internal die or leadframe node. It serves solely for thermal conduction to the PCB and must be soldered to a thermal land with no electrical net assignment to avoid unintended shorts.
