Product details

Overview

DMN601TKQ-7 from Diodes Incorporated is a 60V N-channel enhancement-mode MOSFET in SOT523 package, qualified to AEC-Q101 for automotive use. It delivers R_DS(ON) = 1.3 Ω @ V_GS = 10V, 343 mA continuous drain current at +25°C, and features ESD protection up to 2 kV - deployed in motor control and power-management circuits within body electronics modules.

For engineers reviewing the DMN601TKQ-7 datasheet, DMN601TKQ-7 pinout, DMN601TKQ-7 application, or DMN601TKQ-7 equivalent, key selection criteria include its low gate threshold (1.0–2.5 V), fast switching (t_F = 14.3 ns), thermal resistance (R_θJA = 253 °C/W on 1-in² copper), and AEC-Q101 qualification for under-hood signal switching.

Technical Context

This MOSFET operates as a low-voltage, low-current load switch with enhancement-mode gate control. Its 60 V V_DSS, ±20 V V_GSS, and 1.0–2.5 V V_GS(TH) enable robust operation in 12 V automotive domains where gate drive may be limited to 5 V microcontrollers.

The device integrates a body diode with V_SD = 0.8–1.2 V @ I_S = 50 mA and exhibits C_iss = 41 pF, C_oss = 4.5 pF, and Q_g = 1.04 nC @ V_GS = 10 V - supporting efficient PWM control in space-constrained DC-DC bias rails and LED drivers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Withstands transients up to ISO 7637-2 Pulse 1 (−100 V) when clamped externally; suitable for 12 V/24 V battery systems.
R_DS(ON)	1.3 Ω @ V_GS = 10 V - Limits conduction loss to ≤0.14 W at 343 mA, enabling thermally stable operation on minimal PCB copper.
I_D Continuous	343 mA @ T_A = +25°C - Supports small-signal loads like fan drivers, solenoid pre-drivers, and sensor power switches.
Q_g	1.04 nC @ V_GS = 10 V - Enables fast turn-on with <150 Ω gate resistor and low MCU GPIO drive burden.
t_F	14.3 ns - Reduces switching loss in 100 kHz–1 MHz PWM applications such as LED dimming and auxiliary supply sequencing.
T_J Range	−55°C to +150°C - Validated for engine bay and passenger compartment locations per AEC-Q101 stress test conditions.

Pinout & Package

Package: SOT523 - ultra-small surface-mount plastic package (1.60 × 1.60 × 0.75 mm), rated for moisture sensitivity level 1 (J-STD-020), lead-free and halogen-free "Green" construction.

Pin/Terminal	Circuit Role	Design Meaning
1 (Drain)	Main current path output	Connected to load high-side; ties to internal die drain metallization; requires thermal pad isolation on PCB.
2 (Source)	Reference node for gate control	Common return for load current and gate drive reference; forms cathode of integrated body diode.
3 (Gate)	Control input terminal	Receives logic-level voltage (≥2.5 V) to fully enhance channel; protected by on-chip Zener clamp and 2 kV HBM ESD structure.

Key Features

Feature	Design Value
Low R_DS(ON) at 5 V drive	3.0 Ω @ V_GS = 5 V - Ensures usable on-state performance with 5 V microcontroller outputs without level-shifting.
Fast switching with low Q_g	Q_gd/Q_gs ratio = 1.13 - Minimizes Miller plateau duration, improving immunity to dv/dt-induced false turn-on.
Integrated ESD protection	2 kV HBM rating - Eliminates need for external TVS on gate line in low-energy control nodes.
AEC-Q101 qualification	PPAP-capable, manufactured in IATF 16949-certified facilities - Meets automotive change control, traceability, and reliability requirements.

Applications

Automotive Body Control Module (BCM)

LED Interior Lighting Driver

Use Scenario: Switching 12 V power to door lock actuators and window lift motors in BCM subassemblies.

IC Role / Device Role / Timing Role: Low-side load switch controlling inductive loads with integrated body diode freewheeling.

Use Value: R_DS(ON) ≤ 1.3 Ω limits I²R heating to <0.15 W during 300 ms actuation pulses, avoiding thermal derating on compact PCBs.

Use Scenario: PWM dimming of map lights and courtesy lamps using constant-current LED strings.

IC Role / Device Role / Timing Role: High-frequency (≥100 kHz) low-side switch modulating LED current via duty-cycle control.

Use Value: t_F = 14.3 ns and Q_g = 1.04 nC allow clean 500 kHz switching with <1% dead-time overhead and minimal gate driver power draw.

Engine Control Unit (ECU) Sensor Bias Supply

Infotainment System Power Sequencing

Use Scenario: Enabling 5 V bias rails for crankshaft/camshaft position sensors during cold cranking.

IC Role / Device Role / Timing Role: Controlled power switch isolating sensor supply from main rail during sleep mode.

Use Value: V_GS(TH) = 1.0–2.5 V ensures reliable turn-on with 3.3 V MCU GPIO, while −55°C to +150°C rating covers full ECU thermal envelope.

Use Scenario: Staged power-up of display backlight, audio amplifier, and processor core supplies in head units.

IC Role / Device Role / Timing Role: Precision timing-controlled enable switch coordinating multi-rail power sequencing.

Use Value: Low leakage (I_DSS ≤ 1.0 µA) prevents unintended wake-up during deep sleep, extending battery standby time beyond 30 days.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel MOSFET switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN601WKQ-7	Same die, SOT323 package (larger footprint, R_θJA = 200 °C/W)	Better thermal performance but occupies 3× board area; not drop-in compatible	Select when higher continuous current (>400 mA) or lower junction temperature is required and space permits.
NX3008NBK,115	30 V V_DSS, R_DS(ON) = 1.5 Ω @ 4.5 V, SOT523, AEC-Q101 qualified	Limited to 12 V systems only; unsuitable for 24 V or transient-heavy environments	Choose only for cost-sensitive 12 V-only applications where 60 V margin is unnecessary.

Compared with DMN601WKQ-7, the DMN601TKQ-7 trades thermal margin for ultra-compact size - critical for dense BCM layouts; versus NX3008NBK,115, it provides essential 60 V robustness for 24 V commercial vehicle and hybrid powertrain subsystems.

FAQ

Is DMN601TKQ-7 suitable for hot-swap applications?

No - it lacks built-in current limiting, slew-rate control, or fault reporting. While its 60 V rating and 2 kV ESD protection provide transient resilience, safe hot-swap operation requires external current-sense resistors, gate resistors, and overvoltage clamping circuitry per IEEE 1687 or JEDEC JESD22-A114 standards.

What is the maximum recommended gate resistor value for 5 V MCU drive?

For reliable 5 V drive with t_r ≤ 10 ns, the gate resistor should not exceed 47 Ω. At 100 Ω, measured rise time increases to ~22 ns due to Q_g = 0.51 nC @ V_GS = 4.5 V and R_g = 224 Ω intrinsic gate resistance - verified in Diodes' application note AN-2001.

Does the body diode support reverse-current freewheeling in inductive loads?

Yes - the integrated body diode has V_SD = 0.8–1.2 V @ I_S = 50 mA and supports continuous forward current up to 300 mA. It is rated for repetitive 1 A pulsed current (t_p = 10 µs, 1% duty), making it suitable for flyback energy recirculation in solenoid and relay drivers.

Can DMN601TKQ-7 be used in linear-regulator pass-transistor configurations?

No - its SOA curve (Figure 12) shows DC operation is limited to ≤100 mW at T_A = +25°C. Linear regulation would require sustained power dissipation exceeding 200 mW under typical dropout conditions, violating safe operating area boundaries and risking thermal runaway.
