Product details
Overview
DMN601WKQ-13 from Diodes Incorporated is an AEC-Q101 qualified N-channel enhancement-mode MOSFET in SOT323 package, rated for 60V VDSS, 2.0Ω RDS(ON) @ VGS = 10V, and 300mA continuous drain current at +25°C - designed for automotive motor control, backlighting, and power management circuits.
For engineers reviewing the DMN601WKQ-13 datasheet, DMN601WKQ-13 pinout, DMN601WKQ-13 application, or DMN601WKQ-13 equivalent, this part supports AEC-Q101-compliant designs requiring low gate threshold (1.0–2.5V), ESD-protected gate, <50pF input capacitance, and operation across –65°C to +150°C junction temperature range.
Technical Context
This MOSFET operates as a low-voltage, low-current switching device with enhancement-mode gate control and integrated ESD protection diode. Its 1.6V typical VGS(TH) enables direct drive from 3.3V/5V logic, while 2.0Ω RDS(ON) at 10V ensures minimal conduction loss in space-constrained automotive modules.
The SOT323 package delivers 625°C/W thermal resistance (RθJA) on FR-4 PCBs, supporting 200mW power dissipation. Gate charge and capacitance values (Ciss = 50pF, Coss = 25pF) enable fast switching in PWM-driven LED backlight and small-signal load-switch applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60V - supports 12V/24V automotive supply rails with margin against transients |
| RDS(ON) | 2.0Ω @ VGS = 10V - limits I²R loss to ≤180mW at 300mA, enabling thermally stable operation |
| VGS(TH) | 1.0–2.5V - ensures reliable turn-on from standard microcontroller GPIO without level-shifting |
| Ciss | 50pF - reduces gate drive power and enables >1MHz switching in low-power DC-DC bias circuits |
| PD | 200mW - defines maximum steady-state power handling on standard FR-4 layout |
| TJ Range | –65°C to +150°C - meets extended temperature requirements for under-hood and cabin electronics |
Pinout & Package
Package: SOT323 - surface-mount plastic package with matte tin annealed terminals, moisture sensitivity level 1, UL 94V-0 rated molding compound, and 0.006g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts 0–20V VGS; ESD-protected with internal diode |
| 2 (S) | Source | Reference node for gate drive; connected to ground or low-side return path |
| 3 (D) | Drain | High-side switching node; carries load current up to 300mA continuous |
Key Features
| Feature | Design Value |
|---|---|
| Low gate threshold voltage | 1.6V typical - eliminates need for external gate driver in 3.3V MCU-controlled loads |
| ESD-protected gate | HBM ≥2kV - prevents field failure during assembly and in-cabin ESD events |
| Low input capacitance | Ciss = 50pF - minimizes gate drive energy and propagation delay in high-frequency PWM |
| AEC-Q101 qualification | PPAP-capable, IATF 16949-manufactured - satisfies automotive change control and traceability requirements |
| Green packaging | Halogen- and antimony-free, RoHS 3 compliant - meets EU ELV and OEM sustainability mandates |
Applications
| Automotive Motor Control | LED Backlight Dimming |
|---|---|
Use Scenario: Driving small brushed DC motors in HVAC actuators and mirror positioning systems. IC Role / Device Role / Timing Role: Low-side switch controlling motor direction and duty cycle via PWM from body controller. Use Value: 2.0Ω RDS(ON) limits heat rise to <10°C above ambient at 300mA, eliminating heatsink requirement. |
Use Scenario: Current regulation for instrument cluster and infotainment display LED strings. IC Role / Device Role / Timing Role: Constant-current sink modulated at 1–10kHz to achieve flicker-free dimming. Use Value: Fast switching (Ciss/Coss ratio optimized) maintains PWM fidelity up to 10kHz without shoot-through risk. |
| Automotive Power Management | Body Control Module Load Switching |

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 |
|---|---|---|---|
| DMN601WK-7 | Same die, identical specs, but supplied in 3,000-piece tape-and-reel vs. 10,000-piece for -13 | No functional difference; used where smaller batch sizes align with production planning | Select -7 for prototyping or low-volume builds; -13 for high-volume automotive line replenishment |
| NX3008NBK | Higher RDS(ON) (3.5Ω @ 4.5V), lower VDSS (30V), same SOT323 package and AEC-Q101 rating | Limited to 12V-only systems; unsuitable for 24V commercial vehicles or load-dump tolerant designs | Choose only if VDSS margin is non-critical and gate drive is constrained to ≤4.5V |
Compared with DMN601WKQ-13, the -7 variant offers identical electrical performance with different packaging quantity, while NX3008NBK trades off voltage rating and on-resistance for tighter gate-threshold consistency - making DMN601WKQ-13 optimal for 24V-compatible, low-RDS(ON) automotive signal switching.

FAQ
Is DMN601WKQ-13 suitable for high-side switching configurations?
Yes - its 60V VDSS and ±20V VGS rating support high-side use with appropriate gate drive (e.g., charge pump or bootstrap circuit). However, the SOT323 package's thermal resistance requires careful PCB copper pour design to sustain >200mA in high-side mode without exceeding 150°C junction temperature.
What is the maximum pulsed drain current rating for DMN601WKQ-13?
The datasheet specifies 800mA pulsed drain current (ID) with pulse width ≤10µs and duty cycle ≤1%. This rating applies under single-pulse conditions on FR-4 PCB; sustained pulsing requires derating based on transient thermal impedance curves in Figure 12.
Does DMN601WKQ-13 require external gate resistor for EMI suppression?
Not inherently - its 50pF Ciss and low gate charge allow clean switching without added resistance. However, a 10–47Ω series gate resistor is recommended in high-noise environments (e.g., near ignition systems) to dampen ringing and reduce radiated emissions per CISPR 25 Class 5 requirements.
How does the RDS(ON) variation with temperature affect design margin?
RDS(ON) increases ~1.8× from 25°C to 150°C (per Figure 6), raising conduction loss proportionally. At 150°C junction, 300mA yields ~540mW I²R loss - exceeding the 200mW PD rating. Therefore, thermal design must limit TJ to ≤105°C for full current operation, verified via board-level thermal simulation.
