Product details

Overview

DMN601LTQ-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) = 2 Ω @ V_GS = 10 V, I_D = 356 mA at T_A = +25°C, and features ESD-protected gate, low gate threshold (1.0–2.5 V), and fast switching (t_F = 21.2 ns). It is used in motor control and power-management circuits in automotive body electronics.

For engineers reviewing the DMN601LTQ-7 datasheet, DMN601LTQ-7 pinout, DMN601LTQ-7 application, or DMN601LTQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, low-voltage gate drive compatibility (V_GS(th) ≤ 2.5 V), thermal resistance (R_θJA = 298 °C/W on FR-4), and SOT523 footprint suitability for space-constrained automotive modules.

Technical Context

This MOSFET operates as a low-side switch in 12 V/24 V automotive systems, with gate threshold voltage enabling reliable turn-on from microcontroller GPIOs (e.g., 3.3 V or 5 V logic). Its low input capacitance (C_iss = 47 pF) and gate charge (Q_g = 1.3 nC @ V_GS = 10 V) support efficient high-frequency PWM control up to ~1 MHz in DC-DC and load-switching applications.

The integrated body diode (V_SD = 0.8–1.4 V @ I_S = 115 mA) and reverse recovery characteristics (t_RR = 18.6 ns, Q_RR = 7.7 nC) are specified for inductive flyback management in brushed DC motor drivers and solenoid interfaces, under junction temperatures from –55°C to +150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - supports 24 V automotive systems with ≥2× safety margin against load-dump transients.
R_DS(ON)	2 Ω @ V_GS = 10 V - limits conduction loss to <180 mW at 300 mA, suitable for low-power switching.
I_D (max)	356 mA @ T_A = +25°C - defines continuous current capability on standard FR-4 PCB with 1-inch² copper.
Q_g	1.3 nC @ V_GS = 10 V - enables fast, low-energy gate driving with standard logic-level drivers.
R_θJA	298 °C/W - requires thermal-aware layout (e.g., minimum pad area per datasheet) to sustain >100 mW dissipation.
t_F	21.2 ns - ensures clean turn-off in PWM-driven loads without excessive shoot-through risk.

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), RoHS-compliant, halogen-free, and qualified for automotive reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning
Gate (G)	Control electrode	Accepts logic-level gate drive; ESD-protected; threshold 1.0–2.5 V enables direct MCU interface.
Source (S)	Reference node for gate drive and current return path	Internally connected to substrate; must be tied to local ground plane for stable switching and thermal conduction.
Drain (D)	Power output terminal	Carries switched load current; connects to load (e.g., motor coil or LED string); exposed drain pad aids heat transfer.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive use with PPAP support and IATF 16949 manufacturing - eliminates qualification overhead for Tier 1 suppliers.
Low R_DS(ON) at 5 V drive	3 Ω @ V_GS = 5 V - enables robust operation with 5 V microcontrollers without level-shifting circuitry.
ESD-protected gate	HBM rating ≥2 kV - reduces need for external gate protection in assembly and field environments.
Low C_iss and Q_gd	C_iss = 47 pF, Q_gd = 0.3 nC - minimizes switching losses and improves noise immunity in high-dV/dt automotive environments.

Applications

Automotive Body Control Module (BCM)

LED Interior Lighting Driver

Use Scenario: Switching 12 V loads such as door locks, window lifters, and mirror adjusters in BCM subassemblies.

IC Role / Device Role / Timing Role: Low-side power switch controlled by 3.3 V/5 V MCU GPIO with PWM capability.

Use Value: AEC-Q101 qualification and low gate threshold ensure reliable activation across temperature and battery voltage range (9–16 V).

Use Scenario: Dimmable interior LED lighting (map lights, footwell LEDs) requiring precise current regulation via PWM.

IC Role / Device Role / Timing Role: Fast-switching low-side switch in constant-current LED driver topology.

Use Value: t_F = 21.2 ns and low Q_g enable clean 1–10 kHz PWM dimming without visible flicker or audible noise.

Engine Bay Sensor Interface

Blower Motor Speed Control

Use Scenario: Power gating of non-critical sensors (e.g., ambient temperature, humidity) during sleep mode to reduce quiescent current.

IC Role / Device Role / Timing Role: Load switch enabling/disabling sensor supply rail under MCU command.

Use Value: Ultra-low I_DSS (≤1 µA) and I_GSS (±10 µA) minimize leakage-induced battery drain over extended vehicle idle periods.

Use Scenario: Variable-speed control of HVAC blower motors using discrete MOSFET-based H-bridge half-bridge stage.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN601WKQ-7	Same die, SOT323 package (larger footprint, R_θJA = 242 °C/W), higher I_D = 500 mA.	Better thermal performance but incompatible SOT323 footprint; not drop-in for SOT523 layouts.	Select when board layout allows larger package and higher current (>356 mA) is required.
NX7002AKX	60 V, R_DS(ON) = 3.5 Ω @ 4.5 V, no AEC-Q101 qualification, SOT323.	Lacks automotive qualification and has higher on-resistance; suitable only for industrial/commercial use.	Consider only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated.

Compared with DMN601WKQ-7 and NX7002AKX, the DMN601LTQ-7 uniquely combines AEC-Q101 compliance, SOT523 miniaturization, and gate-drive compatibility down to 5 V - making it the only qualified option for space-constrained automotive modules requiring production-grade reliability.

FAQ

Is DMN601LTQ-7 suitable for 3.3 V logic-level gate drive?

Yes - its gate threshold voltage is specified from 1.0 V to 2.5 V, and R_DS(ON) is characterized down to V_GS = 5 V (3 Ω). At 3.3 V, it achieves partial enhancement; full conduction requires ≥4.5 V. For guaranteed 3.3 V operation, verify actual R_DS(ON) and I_D in your thermal environment using Figure 4 and Figure 7 from the datasheet.

What is the maximum pulsed drain current for DMN601LTQ-7?

The pulsed drain current is rated at 1.2 A for 10 µs pulses with 1% duty cycle. This value assumes proper PCB layout (FR-4, 2 oz copper, minimum pad) and junction temperature remains within –55°C to +150°C. Exceeding this requires derating based on pulse width, duty cycle, and ambient conditions per Figure 12 (SOA curve).

Does DMN601LTQ-7 include an integrated body diode?

Yes - it features a monolithic parasitic body diode between source and drain, with forward voltage V_SD = 0.8–1.4 V at I_S = 115 mA and reverse recovery time t_RR = 18.6 ns. This diode is fully characterized and usable for freewheeling in inductive loads like motors and solenoids.

Can DMN601LTQ-7 be used in high-humidity or under-hood automotive environments?

Yes - it is qualified to AEC-Q101, manufactured in IATF 16949-certified facilities, and packaged in UL 94V-0 mold compound with moisture sensitivity level 1. These attributes ensure robustness against thermal cycling, humidity, and chemical exposure typical in engine bay and chassis-mounted modules.
