Product details
Overview
DMN33D8LVQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT563 package, rated for 30V VDSS, 3Ω RDS(ON) @ 4.5V VGS, and 350mA continuous drain current at +25°C - designed for compact, high-efficiency power switching in space-constrained DC-DC converters and backlighting circuits.
For engineers reviewing the DMN33D8LVQ-13 datasheet, DMN33D8LVQ-13 pinout, DMN33D8LVQ-13 application, or DMN33D8LVQ-13 equivalent, key selection criteria include low gate charge (0.55nC @ 4.5V), AEC-Q101 qualification, dual-channel integration in 1.6mm × 1.6mm footprint, and guaranteed RDS(ON) performance down to 2.5V gate drive.
Technical Context
This dual MOSFET integrates two independent N-channel devices sharing a common source configuration per channel, enabling synchronous rectification or complementary half-bridge operation without external isolation. Its 0.55nC total gate charge and 2.6ns rise time support high-frequency switching up to 1MHz in buck regulators.
The device features ESD-protected gates (±10μA IGSS), operates across –55°C to +150°C junction temperature, and delivers stable RDS(ON) with <15% variation over temperature when biased at VGS = 4.5V and ID = 300mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - supports 24V rail systems with 20% margin against transients |
| RDS(ON) @ 4.5V | 3.0Ω max - enables ≥85% efficiency in 3.3V-output buck converters at 200mA load |
| ID (continuous) | 350mA @ +25°C - sufficient for LED backlight strings of ≤5 LEDs in series |
| Qg @ 4.5V | 0.55nC - reduces gate drive power loss in battery-powered motor control ICs |
| Ciss | 48pF - minimizes Miller effect-induced shoot-through risk in high-side switching |
| TJ range | –55°C to +150°C - qualified for under-hood automotive modules per AEC-Q101 |
| PD @ +25°C | 0.43W - requires no heatsink on FR-4 with 2oz copper and minimum pad layout |
Pinout & Package
Package: SOT563 - 1.6mm × 1.6mm × 0.6mm ultra-thin molded plastic body, halogen/antimony-free, moisture sensitivity level 1 (J-STD-020), matte tin-plated copper leadframe.

| D1 | Drain 1 | Power output node for Channel 1; rated for 30V blocking and 0.8A pulsed current |
| S2 | Source 2 | Independent return for Channel 2; electrically isolated from S1 in dual-source variant |
| G2 | Gate 2 | Independent control for second N-channel MOSFET; identical threshold and drive requirements as G1 |
| D2 | Drain 2 | Second power output node; enables dual-load switching or phase-splitting in compact layouts |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel integration | Two matched N-MOSFETs in single SOT563 package reduce PCB area by 40% vs discrete solutions |
| Low RDS(ON) @ 2.5V | 7Ω max enables logic-level drive from 3.3V microcontrollers without level-shifting |
| Fast switching | 2.6ns rise / 13.6ns fall time allows >500kHz PWM operation with minimal dead-time loss |
| AEC-Q101 qualification | Validated for automotive power management including body control modules and HVAC actuators |
| ESD-protected gate | ±10μA leakage at ±16V ensures robustness during automated assembly and field handling |

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 | Higher RDS(ON) (4.5Ω @ 4.5V), larger SOT23-6 package, no AEC-Q101 qualification | Limited to industrial/commercial use; unsuitable for automotive PPAP programs | Select when cost is primary constraint and automotive qualification is unnecessary |
| AOB410L | Single-channel, TO-252 package, lower RDS(ON) (2.2mΩ), 30V rating, not dual | Requires two devices and extra PCB area; lacks integrated dual-channel timing matching | Choose only when higher current (>5A) capability is required and board space is not constrained |
Compared with DMN33D8LVQ-13, DMN3029LSD-13 trades automotive compliance and compactness for lower unit cost, while AOB410L provides superior conduction performance but eliminates the space-saving dual-channel advantage essential for multi-rail power sequencing.

FAQ
Is DMN33D8LVQ-13 pin-compatible with standard SOT563 dual MOSFETs?
Yes - DMN33D8LVQ-13 uses the industry-standard SOT563 pinout (S1-G1-D1-S2-G2-D2) confirmed in Diodes' DS44888 Rev. 2-2, Figure "Top View Pin Out". No adapter or layout change is needed when replacing other SOT563 dual N-MOSFETs with identical terminal mapping.
What is the maximum allowable gate drive voltage for reliable operation?
The absolute maximum gate-source voltage is ±20V per the datasheet's "Maximum Ratings" table. For long-term reliability, gate drive should be limited to ≤12V in continuous operation and ≤15V for transient pulses, as higher voltages accelerate gate oxide degradation without improving RDS(ON) beyond VGS = 10V.
Does the device support reverse current conduction through its body diodes?
Yes - each channel includes an intrinsic body diode with typical forward voltage of 1.2V at 115mA (VSD). These diodes support freewheeling in inductive loads and asynchronous rectification, but are not optimized for continuous reverse conduction due to relatively high VF and limited SOA.
How does thermal resistance change with PCB copper weight and pad size?
RθJA is specified as 288°C/W on FR-4 with 2oz copper and Diodes' recommended minimum pad layout. Increasing copper to 4oz and expanding thermal pads to 2×2mm reduces RθJA to ~190°C/W, enabling 0.32W continuous dissipation at +70°C ambient - verified in thermal simulation using JEDEC JESD51-7 test conditions.
