Product details

Overview

DMNH6011LK3Q-13 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET rated for 55 V V_DSS, 12 mΩ R_DS(ON) @ 10 V_GS, and 80 A continuous drain current at T_C = +25°C, designed for high-reliability automotive power switching in engine management and DC/DC converters.

For engineers reviewing the DMNH6011LK3Q-13 datasheet, DMNH6011LK3Q-13 pinout, DMNH6011LK3Q-13 application, or DMNH6011LK3Q-13 equivalent, this part supports high-temperature operation up to +175°C, delivers low gate charge (49.1 nC @ 10 V_GS), and features robust unclamped inductive switching capability for demanding automotive load control.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) and fast switching with controlled Q_gd/Q_gs ratio (9.6 nC / 5.3 nC), enabling efficient hard-switching in 12 V and 24 V automotive systems. Its thermal resistance R_θJC of 1.1 °C/W supports high-power density mounting on exposed drain pads.

The device integrates a co-packaged body diode with t_RR = 30.1 ns and Q_RR = 25.7 nC at 100 A/μs di/dt, supporting synchronous rectification and freewheeling in buck and half-bridge topologies without external Schottky supplementation.

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
STL220N4F7AG	40 V V_DSS, 0.75 mΩ R_DS(ON) @ 10 V_GS, 220 A ID, PowerFLAT 5x6 package	Limited to 40 V systems; unsuitable for 48 V or transient-tolerant 24 V designs requiring 55 V rating	Select only for 12 V/24 V low-voltage, ultra-high-current applications where lower R_DS(ON) outweighs voltage margin needs.
IXTQ1N50P	500 V V_DSS, 1.2 Ω R_DS(ON), TO-220 package, non-AEC-Q101	Higher voltage rating but 100× higher R_DS(ON); lacks automotive qualification and thermal performance	Not recommended for automotive use; consider only for industrial AC-line or high-voltage DC applications outside AEC scope.

Compared with STL220N4F7AG and IXTQ1N50P, DMNH6011LK3Q-13 uniquely balances 55 V robustness, 12 mΩ conduction, AEC-Q101 compliance, and TO-252 thermal efficiency-making it optimal for space-constrained, thermally aggressive automotive power stages where voltage margin and qualification are non-negotiable.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The DMNH6011LK3Q-13 has a specified operating junction temperature range of −55°C to +175°C. Continuous operation at +175°C is permitted when thermal design ensures actual T_J does not exceed this limit, verified via R_θJC = 1.1 °C/W and proper PCB copper layout per datasheet Figure 6 and suggested pad dimensions.

Is the TO-252 package lead-free and RoHS compliant?

Yes. The DMNH6011LK3Q-13 uses a matte tin finish over copper leadframe and green molding compound compliant with EU RoHS directives 2002/95/EC, 2011/65/EU, and 2015/863/EU, with bromine and chlorine content below 900 ppm each and antimony below 1000 ppm.

Can this MOSFET be used in synchronous rectification without external diode parallel?

Yes. Its body diode exhibits t_RR = 30.1 ns and Q_RR = 25.7 nC at 100 A/μs, enabling effective synchronous rectification in buck converters up to 250 kHz without external Schottky diodes-provided gate timing avoids cross-conduction.

What is the gate threshold voltage range, and how does it vary with temperature?

V_GS(TH) is specified from 1.0 V to 2.0 V at 250 μA ID. As shown in Figure 8, it decreases linearly with rising junction temperature-approximately 1.45 V at −55°C and 1.05 V at +175°C-supporting stable turn-on behavior across the full automotive temperature range.
