Product details
Overview
DMN67D8LDW-7 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT363 package, rated for 60V V(BR)DSS, 5.0Ω RDS(ON) @ 10V VGS (230mA ID), and qualified to AEC-Q101 for automotive reliability. It delivers low gate threshold (1.0–2.5V), fast switching (tD(ON) = 2.8ns), and ultra-small footprint for space-constrained power management.
For engineers reviewing the DMN67D8LDW-7 datasheet, DMN67D8LDW-7 pinout, DMN67D8LDW-7 application, or DMN67D8LDW-7 equivalent, key selection criteria include dual-channel RDS(ON) matching at 5V/10V drive, thermal resistance (RθJA = 400°C/W on FR-4), and AEC-Q101 qualification for motor control and battery-powered systems.
Technical Context
This dual MOSFET integrates two matched N-channel devices sharing no internal connection-each channel operates independently with separate gate, source, and drain terminals. Its low 1.0–2.5V VGS(TH) enables direct interfacing with 3.3V and 5V logic controllers without level-shifting.
The device uses planar silicon technology optimized for low Ciss (22pF) and Crss (2.5pF), supporting high-frequency PWM operation up to several MHz. Thermal performance is defined for two mounting conditions: 320mW PD with RθJA = 400°C/W (minimum pad layout) and 410mW PD with RθJA = 312°C/W (enhanced 1"×1" 2oz copper).
Key Specifications

Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| DMN67D8LW-7 | Single-channel version in same SOT363 package; identical RDS(ON), V(BR)DSS, and VGS(TH) | Used where only one switch is needed per footprint; no dual-channel coordination required | Select when design requires only one switch and board space permits duplication for redundancy |
| NTJD4152PT1G | Higher RDS(ON) = 8.5Ω @ 4.5V; lower ID = 170mA; same SOT-363 package and AEC-Q101 rating | Targeted at cost-sensitive automotive sensors where lower current and higher on-resistance are acceptable | Choose for legacy designs already using NTJD4152P; verify thermal margin at 170mA continuous load |
Compared with DMN67D8LDW-7, DMN67D8LW-7 reduces channel count but retains identical per-channel specs-ideal for modular layout reuse-while NTJD4152PT1G trades 1.5× higher RDS(ON) for broader distributor availability and longer production lifetime.

FAQ
What is the maximum continuous drain current per channel at 70°C ambient?
At TA = +70°C, the maximum continuous drain current per channel is 180mA when mounted on FR-4 PCB with minimum recommended pad layout. This derating reflects thermal limitations under steady-state conduction, not transient pulse capability. The device supports 0.5A pulsed body diode current and 0.8A pulsed drain current for short durations.
Does DMN67D8LDW-7 support 3.3V logic-level gate drive?
Yes-its gate threshold voltage range of 1.0–2.5V ensures reliable turn-on with 3.3V logic signals. At VGS = 3.3V, typical RDS(ON) is ~4.2Ω (interpolated from Figure 3), delivering ~150mA continuous current with <100mW conduction loss. No external level shifter is required for most 3.3V MCU applications.
How are the two MOSFET channels isolated within the SOT363 package?
The two N-channel MOSFETs share no internal electrical connection: S1/D1/G1 and S2/D2/G2 form two fully independent circuits. Pinout diagrams confirm physical separation-no common source, drain, or substrate tie. This enables true dual-switch operation, including floating half-bridge configurations when used with external bootstrap or isolated gate drivers.
Is the body diode forward voltage specified for both channels?
Yes-VSD is specified as 0.78V (typ) at IS = 115mA and VGS = 0V, applying identically to both channels. The body diode exhibits consistent forward conduction behavior across temperature (−55°C to +150°C), with VF increasing to ~1.5V at 115mA under worst-case conditions, as shown in Figure 9.
