Product details
Overview
DMNH6042SK3Q-13 from Diodes Incorporated is an AEC-Q101-qualified 60V N-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for continuous operation at +175°C junction temperature, with RDS(ON) = 50 mΩ @ VGS = 10 V and 25 A continuous drain current at TC = +25°C. It is designed for automotive power-management functions including solenoid and relay driving.
For engineers reviewing the DMNH6042SK3Q-13 datasheet, DMNH6042SK3Q-13 pinout, DMNH6042SK3Q-13 application, or DMNH6042SK3Q-13 equivalent, key selection criteria include its 100% unclamped inductive switching rating, low input capacitance (Ciss = 584 pF), and thermal robustness up to +175°C - critical for under-hood automotive modules requiring PPAP-compliant, IATF 16949-manufactured components.
Technical Context
This MOSFET employs a planar silicon process optimized for high-temperature reliability and low RDS(ON) stability across -55°C to +175°C. Its gate threshold voltage (VGS(TH) = 1.0–3.0 V) enables compatibility with 3.3 V and 5 V logic-level drive, while its normalized RDS(ON) variation remains ≤2.4× over full temperature range at VGS = 10 V.
The device features integrated body diode with tRR = 12.9 ns and QRR = 5.4 nC, supporting fast-switching DC-DC and load-switch applications. Its RθJC = 3.2°C/W and RθJA = 43°C/W (2 oz copper, thermal bias) enable efficient heat transfer from junction to case and ambient under pulsed and steady-state conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage before avalanche; supports 48 V automotive systems with margin. |
| RDS(ON) | 50 mΩ @ VGS = 10 V - Low conduction loss at full gate drive; enables <1.25 W I²R loss at 5 A. |
| ID (continuous) | 25 A @ TC = +25°C - Sustains high-current loads without derating when mounted on thermally enhanced PCB. |
| TJ max | +175°C - Enables placement in high-ambient zones (e.g., engine bay, transmission control units). |
| Ciss | 584 pF - Low input capacitance reduces gate drive power and speeds switching transitions. |
| tRR | 12.9 ns - Fast body diode recovery minimizes switching losses in synchronous rectification or flyback topologies. |
| Qg | 8.8 nC @ VGS = 10 V - Enables efficient gate driving with standard low-side drivers (e.g., TC4427, UCC27517). |
Pinout & Package
Package: TO252 (DPAK), surface-mount, with exposed drain pad for thermal and electrical connection. Molded green compound (UL 94V-0), matte tin annealed terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Low-side reference node; connects to ground or return path; carries full load current. |
| Pin 2 (Gate) | Control input | High-impedance MOSFET gate; requires <8.8 nC charge for full turn-on; sensitive to ESD. |
| Pin 3 (Drain) | Power output | Exposed copper pad (bottom side); electrically and thermally connected to drain; must be soldered to large copper pour. |
Key Features
| Feature | Design Value |

| Low RDS(ON) @ 4.5 V | 65 mΩ at VGS = 4.5 V - supports logic-level drive from microcontrollers and automotive MCUs without gate boosters. |
Applications
| Engine Control Unit (ECU) Load Switching | Automotive HVAC Blower Motor Driver |
|---|---|
Use Scenario: High-side or low-side switching of fuel injector solenoids and idle air control valves in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Power switch controlling 12–48 V inductive loads with precise PWM timing and fast turn-off to prevent coil saturation.

IC Role / Device Role / Timing Role: Load switch enabling controlled inrush current limiting and fault-isolated rail sequencing. Use Value: Low leakage (IDSS ≤ 1 µA) prevents standby power drain; AEC-Q101 qualification ensures long-term reliability in vibration-prone mounting locations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL130N6LF8AG | RDS(ON) = 4.5 mΩ @ 10 V (lower), but rated only to +150°C; TO263 package. | Better conduction efficiency but less thermal headroom; larger footprint and higher cost. | Select if system prioritizes ultra-low RDS(ON) and has ample board space/cooling. |
| IXTP50N10P | 100 V rating, RDS(ON) = 22 mΩ @ 10 V, +175°C rated, TO220 package. | Higher voltage margin and lower RDS(ON), but through-hole mounting and no AEC-Q101 certification. | Select for non-automotive industrial 48 V systems where surface-mount is not required. |
Compared with STL130N6LF8AG and IXTP50N10P, the DMNH6042SK3Q-13 uniquely balances AEC-Q101 compliance, +175°C capability, TO252 footprint, and 60 V/50 mΩ performance - making it optimal for space-constrained, thermally demanding automotive modules requiring PPAP traceability.

FAQ
What is the maximum allowable gate-source voltage for DMNH6042SK3Q-13?
The absolute maximum gate-source voltage (VGSS) is ±20 V. Exceeding this rating risks permanent gate oxide damage. For reliable operation, gate drive should be limited to 10 V for full enhancement or 4.5 V for logic-level compatibility, with transient spikes clamped using Zener diodes or gate resistors per Diodes' application note AN-2001.
Does DMNH6042SK3Q-13 require a heatsink in typical automotive applications?
No dedicated heatsink is required when mounted on a 2 oz copper PCB with ≥1 inch² thermal pad connected to the exposed drain. At 25 A continuous current and TC = +70°C, junction temperature remains within +175°C limit due to RθJC = 3.2°C/W and optimized pad layout per Diodes' recommended footprint.
How does the body diode performance impact flyback or freewheeling use cases?
The integrated body diode has tRR = 12.9 ns and QRR = 5.4 nC, enabling efficient freewheeling in inductive loads without external diode supplementation. Its low VSD (0.8–1.2 V at 2.6 A) reduces conduction loss, but for high-frequency (>100 kHz) synchronous rectification, an external Schottky may still be preferred to minimize reverse recovery losses.
Is DMNH6042SK3Q-13 compatible with lead-free reflow profiles?
Yes - it uses matte tin-annealed terminals and complies with J-STD-020 moisture sensitivity level 1. The device supports standard lead-free reflow profiles (peak 260°C, 60 sec max), and its green molding compound meets UL 94V-0 flammability requirements without halogen or antimony additives.
