Product details
Overview
DMNH6042SK3-13 from Diodes Incorporated is a 60V, 25A N-channel enhancement-mode MOSFET in TO252 (DPAK) package, featuring 50mΩ RDS(ON) @ VGS = 10V and 65mΩ @ 4.5V, rated for continuous operation up to +175°C junction temperature, and qualified to AEC-Q101 - designed for high-efficiency DC-DC converters and automotive-grade power management.
For engineers reviewing the DMNH6042SK3-13 datasheet, DMNH6042SK3-13 pinout, DMNH6042SK3-13 application, or DMNH6042SK3-13 equivalent, key selection criteria include its low RDS(ON) at 4.5V gate drive, robust 100% unclamped inductive switching rating, thermal performance under high ambient conditions, and RoHS-compliant green packaging with matte tin annealed terminals.
Technical Context
This MOSFET employs planar silicon process technology optimized for low conduction loss and fast switching trade-off, with gate charge Qg of 8.8nC at VGS = 10V and 4.2nC at 4.5V, enabling efficient operation in synchronous buck topologies. Its body diode exhibits tRR = 12.9ns and QRR = 5.4nC under IF = 2.6A, di/dt = 100A/μs.
The device's thermal resistance RθJC is 3.2°C/W, and RθJA is 43°C/W on 2oz copper FR-4 with thermal bias - confirming suitability for compact, thermally constrained power stages. Its ±20V VGSS rating supports gate drive margin in noisy environments.
Key Specifications

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 |
|---|---|---|---|
| STL130N6LF8AG | 60V, 130A, RDS(ON) = 3.2mΩ @ 10V; SO-8FL package; lower RDS(ON) but higher Qg (32nC); not AEC-Q101 qualified. | Targeted at high-current consumer/industrial SMPS where board space is limited and thermal mass is high; unsuitable for automotive under-hood use. | Select when peak current exceeds 25A and PCB layout allows larger gate drive capability; avoid where AEC-Q101 or +175°C operation is mandatory. |
| IXTP50N065T | 65V, 50A, RDS(ON) = 13mΩ @ 10V; TO-220 package; higher thermal resistance (RθJC = 1.5°C/W), no AEC-Q101 qualification. | Designed for through-hole, heatsink-mounted applications such as UPS and industrial motor drives; lacks surface-mount compatibility and automotive qualification. | Choose for legacy through-hole designs needing higher current headroom; reject for space-constrained or automotive-qualified designs. |
Compared with STL130N6LF8AG and IXTP50N065T, DMNH6042SK3-13 uniquely balances moderate current (25A), low gate charge (8.8nC), AEC-Q101 qualification, and +175°C operation in a compact TO252 footprint - making it optimal for thermally demanding, automotive-adjacent, and high-reliability surface-mount power stages.

FAQ
What is the maximum continuous drain current at TC = 70°C?
The DMNH6042SK3-13 supports 17A continuous drain current at case temperature of +70°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by package dissipation and PCB layout; actual achievable current depends on copper area, airflow, and ambient conditions.
Is the body diode suitable for synchronous rectification?
No - the integrated body diode has tRR = 12.9ns and QRR = 5.4nC, which is acceptable for freewheeling but not optimized for synchronous rectification. For that function, an external Schottky or dedicated synchronous MOSFET with lower QRR is recommended.
Does DMNH6042SK3-13 require a gate resistor for stability?
Yes - a series gate resistor (typically 5–20Ω) is required to dampen parasitic oscillation caused by gate-drain capacitance (Crss = 27pF) and PCB inductance. Without it, ringing can exceed VGSS limits and cause premature failure, especially at high dV/dt edges.
How does the 100% UIS rating translate to real-world reliability?
The 100% UIS rating means each unit is individually tested to withstand 3.5A avalanche current and 65mJ energy without parametric shift or catastrophic failure. In practice, this allows safe operation in inductive load switching (e.g., solenoids, relays) without external clamping components, reducing BOM count and board area.
