Product details
Overview
DMN61D9UDWQ-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET qualified to AEC-Q101 for automotive use, featuring 60 V VDSS, 2.0 Ω RDS(ON) @ VGS = 5.0 V, and 318 mA continuous drain current at +25°C in SOT363 package - deployed in motor control and power management circuits within body electronics modules.
For engineers reviewing the DMN61D9UDWQ-7 datasheet, DMN61D9UDWQ-7 pinout, DMN61D9UDWQ-7 application, or DMN61D9UDWQ-7 equivalent, key selection criteria include low gate threshold (0.5–1.0 V), ultra-small footprint (SOT363), AEC-Q101 qualification, and dual-channel integration for space-constrained automotive signal switching.
Technical Context
This dual MOSFET integrates two matched N-channel devices in a single SOT363 package with independent gate, source, and drain terminals per channel. Each channel supports 60 V blocking voltage and exhibits low RDS(ON) down to 1.4 Ω (typ) at VGS = 5 V, enabling efficient low-power switching in battery-supplied systems.
Gate threshold voltage ranges from 0.5 V to 1.0 V, allowing direct drive from 1.8 V/2.5 V logic without level-shifting. Integrated ESD protection and low input capacitance (Ciss = 39 pF) support robust operation in noisy automotive environments while maintaining fast switching (tD(ON) = 5.2 ns, tF = 19 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - supports 12 V/24 V automotive supply rails with margin against load-dump transients |
| RDS(ON) @ VGS = 5 V | 1.4–2.0 Ω (typ–max) - enables <100 mW conduction loss at 250 mA, suitable for low-duty-cycle signal switching |
| VGS(TH) | 0.5–1.0 V - ensures reliable turn-on from 1.8 V microcontroller GPIOs without external biasing |
| Ciss | 39 pF - minimizes gate drive energy and propagation delay in high-frequency PWM control |
| tF | 19 ns - supports >5 MHz switching in discrete driver stages for LED dimming or sensor interface |
| TJ Range | −55°C to +150°C - meets under-hood temperature requirements for engine bay and HVAC actuators |
| Package | SOT363 - 2.2 × 2.1 mm footprint with 0.65 mm pitch, compatible with standard reflow profiles and AOI inspection |
Pinout & Package
SOT363 is a 6-pin ultra-small surface-mount package with dual-drain, dual-source, dual-gate configuration and integrated gate protection diodes. Pin numbering follows JEDEC MO-178AA standard with top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| S1 | Source of Channel 1 | Low-side return path for first MOSFET; tied to ground or common reference in half-bridge configurations |
| D1 | Drain of Channel 1 | High-side output node for Channel 1; connects to load or pull-up network in switch-mode applications |
| G1 | Gate of Channel 1 | Control input for Channel 1; requires <100 nC total gate charge for full turn-on at 4.5 V |
| D2 | Drain of Channel 2 | Independent high-side output for second MOSFET; enables dual-load control in compact space |
| S2 | Source of Channel 2 | Separate return path for Channel 2; allows floating or isolated source connections in differential sensing |
| G2 | Gate of Channel 2 | Independent control input; supports asynchronous or synchronized switching with Channel 1 |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, HAST, and ESD testing per IATF 16949 manufacturing |
| Ultra-low VGS(TH) | Enables direct interfacing with 1.8 V/2.5 V logic outputs - eliminates level-shifters in MCU-peripheral interfaces |
| ESD protection | HBM rating ≥2 kV on all pins - sustains handling and board-level ESD events without external TVS diodes |
| Low Ciss/Coss ratio | Ciss = 39 pF, Coss = 18 pF - improves Miller immunity and reduces switching losses in high-dV/dt environments |
| Green packaging | Halogen- and antimony-free, lead-free, RoHS 3 compliant - satisfies EU ELV and OEM chemical compliance mandates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN61D8FDWQ-7 | Lower RDS(ON) (1.2 Ω @ 5 V), higher ID (400 mA), same SOT363 package and AEC-Q101 rating | Better suited for higher-current loads like fan drivers; requires tighter thermal layout due to increased PD | Select when >300 mA continuous current or lower conduction loss is required without changing PCB footprint |
| NTJD4152P | Higher VDSS (60 V), but higher VGS(TH) (1.0–2.5 V), no AEC-Q101 qualification, SOT-363 package | Limited to industrial or consumer applications; not approved for production automotive ECUs | Acceptable for prototyping or non-safety-critical systems where qualification documentation is not mandated |
Compared with DMN61D9UDWQ-7, DMN61D8FDWQ-7 delivers lower on-resistance for improved efficiency in higher-current automotive loads, while NTJD4152P offers cost-sensitive alternatives where AEC-Q101 compliance is not required - both retain pin compatibility but differ in thermal performance and qualification scope.

FAQ
Is DMN61D9UDWQ-7 suitable for 12 V automotive battery monitoring circuits?
Yes - its 60 V VDSS, −55°C to +150°C operating range, and AEC-Q101 qualification make it appropriate for battery-sense paths in junction box modules. The low 0.5–1.0 V VGS(TH) ensures turn-on even during cold-cranking (down to ~6 V), and RDS(ON) stability over temperature maintains measurement accuracy across ambient conditions.
What is the maximum safe continuous current per channel at +85°C ambient?
At +85°C ambient with 2 oz copper FR-4 board and recommended pad layout, the maximum continuous drain current per channel is 254 mA (per datasheet Note 6). This is derived from thermal derating using RθJA = 285°C/W and TJ(max) = 150°C, limiting power dissipation to 0.44 W per channel.
Does DMN61D9UDWQ-7 require external gate resistors for EMI suppression?
No external gate resistor is required for basic functionality, but a 10–47 Ω series resistor is recommended to dampen ringing caused by PCB trace inductance and reduce EMI in high-speed switching (>100 kHz). The device's low Qg (0.6 nC) and Rg (238 Ω) allow controlled edge rates without compromising switching speed.
Can DMN61D9UDWQ-7 be used in reverse-biased configurations (source-to-drain conduction)?
Yes - each channel includes an intrinsic body diode with VSD = 0.75–1.4 V at 115 mA. It supports reverse current flow in flyback or freewheeling paths, such as in brushed DC motor H-bridge snubbing or LED cathode switching, though dedicated Schottky diodes may be preferred for lower forward drop in high-efficiency designs.
