Product details
Overview
DMN3270UVT-13 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in TSOT26 package, optimized for low RDS(ON) at 2.5V and 4.5V gate drive, with 270mΩ @ VGS = 4.5V, 1.6A continuous drain current, and AEC-Q101 qualification-used in battery management systems and EV auxiliary power switching.
For engineers reviewing the DMN3270UVT-13 datasheet, DMN3270UVT-13 pinout, DMN3270UVT-13 application, or DMN3270UVT-13 equivalent, key selection criteria include gate threshold voltage (0.35–0.9V), thermal resistance (118°C/W on 1"×1" 2oz copper), and low-input capacitance (161pF Ciss) for high-efficiency DC-DC control in space-constrained automotive modules.
Technical Context
This MOSFET employs a trench-gate silicon process to achieve low on-resistance while maintaining fast switching speed (tD(ON) = 163ns, tF = 674ns) and robust body diode performance (QRR = 426nC). Its gate protection diode structure and ESD-hardened gate support reliable operation in noisy 12V/24V vehicle subsystems.
The device operates across –55°C to +150°C junction temperature, with RDS(ON) normalized to 1.2× at 125°C (VGS = 4.5V), and features a 1kΩ gate resistor (Rg) and 338kΩ gate-source resistor (Rgs) integrated into its terminal design for controlled turn-on/turn-off behavior.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LFD-7 | Lower RDS(ON) (25mΩ @ 4.5V), higher ID (6.5A), same TSOT26 package | Requires higher gate drive strength; not optimized for 2.5V logic | Select when higher current and lower conduction loss outweigh gate drive compatibility needs |
| AO3400 | Higher RDS(ON) (44mΩ @ 10V), no AEC-Q101 qualification, same pinout | Limited to commercial-temperature industrial use; lacks automotive reliability validation | Select only for non-automotive applications where cost is primary constraint and AEC-Q101 is not required |
Compared with DMN3025LFD-7 and AO3400, the DMN3270UVT-13 uniquely balances 2.5V logic compatibility, AEC-Q101 compliance, and thermally efficient TSOT26 packaging-making it optimal for space-limited, automotive-grade power switches where gate drive voltage headroom is constrained.

FAQ
What is the maximum gate-source voltage rating for DMN3270UVT-13?
The absolute maximum gate-source voltage (VGSS) is +5V and –0.5V. Exceeding +5V risks permanent gate oxide damage, while negative voltage beyond –0.5V may forward-bias the integrated gate protection diode. This rating is validated per JEDEC JESD22-A114 and confirmed in the DS39154 datasheet Section "Maximum Ratings".
Does DMN3270UVT-13 require an external gate resistor for automotive PWM applications?
No external gate resistor is required for typical 100–500kHz PWM operation due to the integrated 1kΩ gate resistance (Rg). This value provides inherent damping against ringing and reduces EMI without compromising switching speed-verified in Figure 11 (Gate Charge) and dynamic characterization data in DS39154 Rev. 2–2.
How does the body diode performance impact reverse recovery in BMS applications?
The body diode exhibits tRR = 371ns and QRR = 426nC at IF = 1A, di/dt = 100A/μs. In BMS cell-balancing circuits, this enables clean commutation during bidirectional switching, minimizing voltage overshoot and reducing snubber component count-confirmed in Figure 9 (Diode Forward Voltage) and Section "Electrical Characteristics".
Is the exposed pad of the TSOT26 package electrically connected, and how should it be handled on PCB?
Yes-the exposed pad is internally connected to the Source terminals (Pins 1 and 4) and must be soldered to a large copper pour for thermal conduction. The recommended pad layout (X = 0.700mm, Y = 1.000mm, C = 0.950mm) is specified in DS39154 page 6 and ensures RθJA = 118°C/W on 1"×1" 2oz copper, as verified in thermal testing per Note 6.
