Product details
Overview
DMN3270UVT-7 from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in TSOT26 package, optimized for low RDS(ON) (270 mΩ @ VGS = 4.5V) and fast switching in space-constrained power management circuits. It delivers 1.6A continuous drain current at +25°C and supports battery management systems and EV auxiliary power rails.
For engineers reviewing the DMN3270UVT-7 datasheet, DMN3270UVT-7 pinout, DMN3270UVT-7 application, or DMN3270UVT-7 equivalent, key selection criteria include gate threshold voltage (0.35–0.9V), thermal resistance (118 °C/W on 1"×1" 2oz copper), body diode forward voltage (0.6–1.0V), and AEC-Q101 qualification for automotive reliability.
Technical Context
This MOSFET employs planar trench-gate technology to balance conduction loss and switching speed. Its low input capacitance (Ciss = 161 pF) and fast turn-on delay (163 ns) enable efficient operation in DC-DC converters and load switches operating up to 1 MHz.
The device integrates ESD-protected gate structure and features dual gate protection diodes per internal schematic. Its RDS(ON) remains stable across -55°C to +150°C junction temperature, with normalized variation ≤1.6× at 150°C under VGS = 4.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage before avalanche breakdown; suitable for 24V system rails with margin. |
| RDS(ON) | 270 mΩ @ VGS = 4.5V - Enables <100 mW conduction loss at 0.65A; critical for thermally limited PCB layouts. |
| ID (continuous) | 1.6 A @ TA = +25°C - Sustains typical load-switch currents without forced cooling on minimal copper area. |
| Qg | 3.07 nC @ VGS = 4.5V - Low gate charge reduces driver power and enables use with low-current GPIOs or microcontroller pins. |
| RθJA | 118 °C/W - Measured on 1"×1" FR-4 with 2oz copper; defines thermal derating slope for ambient temperature design. |
| VGS(TH) | 0.35–0.9 V - Ultra-low threshold enables direct drive from 1.8V/3.3V logic without level shifters. |
| Ciss | 161 pF - Limits high-frequency gate drive losses and EMI generation in switching nodes. |
Pinout & Package
Package: TSOT26 - ultra-thin surface-mount package (2.9 × 1.6 × 0.6 mm), moisture sensitivity level 1, RoHS-compliant tin-finished copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts logic-level gate drive; protected by integrated Zener diode. |
| 2 (S) | Source | Reference node for gate drive; connected to power ground or return path in high-side configuration. |
| 3 (D) | Drain | Power output terminal; carries load current; electrically tied to internal body diode anode. |
| 4 (S) | Source (tied) | Second source connection; paralleled internally with Pin 2 to reduce source inductance and improve switching stability. |
| 5 (D) | Drain (tied) | Second drain connection; paralleled internally with Pin 3 to lower drain inductance and minimize voltage overshoot. |
| 6 (G) | Gate (tied) | Second gate connection; paralleled internally with Pin 1 to reduce gate loop inductance and suppress oscillation. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | Lower RDS(ON) (25 mΩ @ 4.5V), larger SO-8 package, higher Qg (12.5 nC) | Requires more PCB area and stronger gate driver; better for high-current (>3A), lower-frequency (<500 kHz) designs | Select when thermal budget permits larger footprint and peak current exceeds 2A. |
| AO3414 | Higher RDS(ON) (44 mΩ @ 4.5V), same TSOT26 package, no AEC-Q101 qualification | Lacks automotive reliability validation; suitable for consumer-grade cost-sensitive applications only | Select only for non-automotive, non-safety-critical designs where AEC-Q101 is not required. |
Compared with DMN3270UVT-7, DMN3025LSD-13 trades compact size for lower conduction loss and higher drive demand, while AO3414 offers identical form factor but lacks automotive qualification and has higher on-resistance-making DMN3270UVT-7 optimal for space-constrained, AEC-Q101–mandated 1–2A loads.

FAQ
What is the maximum junction temperature rating for DMN3270UVT-7?
The DMN3270UVT-7 is rated for continuous operation from –55°C to +150°C junction temperature. Its RDS(ON) increases predictably with temperature, remaining within 1.6× nominal value at 150°C under VGS = 4.5V, enabling robust thermal design in sealed enclosures.
Does DMN3270UVT-7 require external gate protection components?
No external gate protection is required in standard 24V applications. The device integrates gate-source Zener clamps and ESD protection rated to ±2000V HBM, validated per AEC-Q101. External series gate resistors may still be used for EMI suppression in high-dI/dt layouts.
Can DMN3270UVT-7 be used in high-side switching configurations?
Yes-it supports high-side switching when paired with a gate driver capable of providing VGS ≥ 4.5V above the source potential. Its 5V maximum gate-source rating and low Qg make it compatible with bootstrap or charge-pump drivers in half-bridge topologies.
Is the TSOT26 package of DMN3270UVT-7 compatible with standard reflow profiles?
Yes-the TSOT26 package is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260°C. Its moisture sensitivity level 1 allows unlimited floor life at ≤30°C/60% RH, eliminating bake requirements prior to assembly.
