Product details
Overview
DMN6068LK3Q-13 from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET in TO252 (DPAK) package, qualified to AEC-Q101 and PPAP-capable for automotive use. It delivers RDS(ON) = 68 mΩ @ VGS = 10 V, ID = 8.5 A at TA = +25°C, and supports 37.5 mJ single-pulsed avalanche energy - ideal for motor control and DC-DC converter high-side switching.
For engineers reviewing the DMN6068LK3Q-13 datasheet, DMN6068LK3Q-13 pinout, DMN6068LK3Q-13 application, or DMN6068LK3Q-13 equivalent, key selection criteria include its AEC-Q101 qualification, low RDS(ON) at 4.5 V (100 mΩ), fast switching (tF = 8.7 ns), and thermal resistance RθJC = 3.03 °C/W for high-power density board layouts.
Technical Context
This MOSFET employs planar silicon technology with optimized gate oxide and drain-source layout to achieve robust UIS performance and stable threshold voltage (VGS(TH) = 1.0–3.0 V) across temperature. Its body diode exhibits tRR = 145 ns and QRR = 929 nC, enabling efficient synchronous rectification in buck converters.
The device operates within –55°C to +150°C junction range and features a thermally enhanced exposed drain pad for direct PCB copper thermal coupling. Its gate charge profile (Qg = 10.3 nC @ 10 V) supports high-frequency PWM operation up to 500 kHz while maintaining low drive loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - supports 48 V automotive bus systems with 20 % derating margin |
| RDS(ON) | 68 mΩ @ VGS = 10 V - enables <1.5 W conduction loss at 8.5 A continuous current |
| ID | 8.5 A @ TA = +25°C - suitable for medium-power motor drivers and power supplies |
| EAS | 37.5 mJ - withstands inductive kickback in relay and solenoid drive circuits |
| RθJC | 3.03 °C/W - allows >15 W power dissipation with minimal case-to-heatsink ΔT |
| Qg | 10.3 nC @ VGS = 10 V - reduces gate driver power demand in high-frequency SMPS |
| tF | 8.7 ns - minimizes switching transition time and associated crossover losses |
Pinout & Package

| G (Gate) | Control input for channel conduction | High-impedance MOS gate requiring <100 nA leakage; sensitive to ESD - requires series resistor (6 Ω typical) and local decoupling |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL60N3LLH6 | RDS(ON) = 3.3 mΩ @ 10 V (lower), but rated only to 30 V - insufficient for 48 V systems | Not suitable for 48 V automotive bus applications due to lower VDSS | Select only for 12–24 V low-voltage motor drives where ultra-low RDS(ON) outweighs voltage margin needs |
| IXTP50N10P | Higher RDS(ON) = 100 mΩ @ 10 V, TO-220 package - no exposed drain pad, higher RθJC = 1.5 °C/W | Lacks AEC-Q101 qualification and surface-mount compatibility for automated assembly | Acceptable for industrial non-automotive DC-DC where manual assembly and lower cost are prioritized over thermal performance |
Compared with STL60N3LLH6 and IXTP50N10P, the DMN6068LK3Q-13 uniquely balances 60 V rating, AEC-Q101 compliance, TO252 thermal performance, and 4.5 V logic-level drive - making it the only drop-in solution for automotive 48 V power stages requiring PPAP traceability and high-reliability packaging.

FAQ
What is the maximum gate-source voltage rating for DMN6068LK3Q-13 in automotive applications?
The absolute maximum VGS is ±20 V per datasheet, but AEC-Q101 qualification restricts operational gate drive to ±16 V to ensure long-term reliability under automotive temperature cycling and humidity conditions. Exceeding ±16 V may accelerate gate oxide degradation and void PPAP compliance.
Does DMN6068LK3Q-13 require a gate resistor, and what value is recommended?
Yes - a series gate resistor is required to dampen ringing and limit peak gate current. Diodes recommends 6.0 Ω (as used in switching characterization) for 10 V drive with 12 A load; values between 4.7 Ω and 10 Ω balance switching speed and EMI suppression in automotive EMC-compliant layouts.
Can DMN6068LK3Q-13 be used in parallel configurations for higher current handling?
Yes, but only with matched devices and symmetrical PCB layout. The positive temperature coefficient of RDS(ON) enables inherent current sharing; however, gate drive skew must be <2 ns and thermal coupling between devices must be uniform to prevent thermal runaway above 15 A total current.
Is the TO252 package of DMN6068LK3Q-13 compatible with standard DPAK footprints?
Yes - it uses industry-standard TO252 (DPAK) dimensions per JEDEC MO-235, with exact pin spacing (2.286 mm pitch), outline (6.10 × 6.58 mm), and thermal pad geometry. The "K3Q" suffix confirms full mechanical and solder-reflow compatibility with legacy DPAK assembly lines and stencil designs.
