Product details

Overview

DMN5L06KQ-7 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in SOT23 package, rated for 50V V_DS, 2.0Ω R_DS(on) at V_GS = 5.0V, and 300mA continuous drain current. It serves as a low-voltage load switch in automotive battery management systems, delivering fast switching, 1.0V max gate threshold, and 2kV ESD protection.

For engineers reviewing the DMN5L06KQ-7 datasheet, DMN5L06KQ-7 pinout, DMN5L06KQ-7 application, or DMN5L06KQ-7 equivalent, key selection criteria include gate threshold voltage compatibility with 1.8V–3.3V logic, R_DS(on) stability across temperature, SOT23 thermal derating behavior, and AEC-Q101 qualification status for under-hood use.

Technical Context

This MOSFET employs planar silicon technology optimized for low R_DS(on) while preserving fast switching speed (C_iss = 50pF, C_rss = 5.0pF) and low gate charge. Its 1.0V max V_GS(th) enables direct drive from low-voltage microcontrollers without level-shifting.

The device features integrated gate-body diode protection and exhibits <60nA I_DSS at 50V V_DS, supporting high-impedance off-state integrity in power rail control. Thermal resistance R_θJA is 357°C/W on FR-4 PCB, defining its safe operating area under pulsed and continuous loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Rating	50V - supports 12V/24V automotive battery rails with margin against transients
R_DS(on)	2.0Ω @ V_GS = 5.0V - limits conduction loss to ≤0.3W at 300mA, enabling compact thermal design
V_GS(th)	0.49–1.0V - ensures reliable turn-on with 1.8V I/O logic and reduces risk of partial enhancement
I_D Continuous	300mA @ T_A = +25°C - suitable for low-power sensor modules and LED drivers
C_iss/C_rss	50pF / 5.0pF - enables sub-µs switching with minimal gate drive energy
ESD Rating	2kV HBM - protects against handling-induced discharge during assembly and field operation
AEC-Q101	Qualified - validated for automotive temperature range (−40°C to +125°C ambient) and reliability stress tests

Pinout & Package

Package: SOT23 - surface-mount, 3-pin plastic case with matte tin-plated Alloy 42 leadframe; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.008g.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Current return path for load current	Connected to system ground or common reference; low-inductance layout critical for switching noise control
2 (Gate)	Control terminal for channel conduction	High-impedance input requiring <50nA leakage; sensitive to ESD and routing stubs
3 (Drain)	Power output node to load	Carries switched load current; routed away from sensitive analog traces to avoid coupling

Key Features

Feature	Design Value
Low gate threshold voltage	V_GS(th) ≤ 1.0V enables direct interface with 1.8V/2.5V logic without external level shifters
Low input capacitance	C_iss = 50pF minimizes gate drive power and speeds up turn-on/turn-off transitions
Automotive qualification	AEC-Q101 compliance confirms suitability for engine control, body electronics, and infotainment power domains
Green packaging	Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) meets global environmental mandates

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel load switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN5L06K-7	Commercial-grade version; identical electrical specs but not AEC-Q101 qualified	Limited to non-automotive environments (e.g., consumer portables, industrial controls)	Select when AEC-Q101 is not required and cost sensitivity is higher
DMN3022LSD-13	30V V_DS, 32mΩ R_DS(on) @ 4.5V, SO-8 package, higher current rating (3.2A)	Requires PCB real estate for SO-8; suited for higher-power 5V rail switching	Choose only if ≥1A load current and 30V max rail are needed; not drop-in compatible

Compared with DMN5L06K-7 and DMN3022LSD-13, DMN5L06KQ-7 uniquely balances AEC-Q101 compliance, SOT23 footprint, and 1.0V gate threshold-making it optimal for space-constrained, low-voltage automotive load switching where qualification and logic-level drive are mandatory.

FAQ

What is the maximum allowable junction temperature for DMN5L06KQ-7?

The absolute maximum junction temperature is +150°C, with continuous operation limited to +125°C ambient per AEC-Q101 requirements. Derating begins at +25°C ambient, with power dissipation reduced linearly to zero at +125°C ambient based on R_θJA = 357°C/W on FR-4 PCB.

Can DMN5L06KQ-7 be used with 1.8V GPIO without external level shifting?

Yes. With V_GS(th) guaranteed ≤1.0V and typical value of 0.49V, the device fully enhances at 1.8V gate drive, delivering R_DS(on) ≤2.5Ω at 50mA. This eliminates need for level shifters in ultra-low-voltage microcontroller interfaces.

How does the 2kV HBM ESD rating impact board-level design?

The 2kV Human Body Model rating means the gate oxide is robust enough to survive standard handling and reflow without additional protection diodes. However, layout best practices-short gate traces, ground-plane proximity, and avoidance of floating nodes-remain essential to prevent field-induced failure.

Is the SOT23 package thermally adequate for 300mA continuous operation?

Yes, when mounted on a standard 1-inch² FR-4 PCB with 1oz copper, the device sustains 300mA continuously at +25°C ambient. At +85°C ambient, derated current drops to ~180mA per the 357°C/W R_θJA and 350mW P_D limit-confirming suitability for most under-dash automotive zones.
