Product details
Overview
DMN33D8LDWQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SOT363 package, qualified to AEC-Q101 for automotive use. It delivers 30V VDSS, 3Ω RDS(ON) @ 4.5VGS, 250mA ID at +25°C, and features ESD protection, low input capacitance (48pF Ciss), and fast switching (tF = 13.6ns). It is deployed in motor control, DC-DC converters, and LED backlighting circuits.
For engineers reviewing the DMN33D8LDWQ-13 datasheet, DMN33D8LDWQ-13 pinout, DMN33D8LDWQ-13 application, or DMN33D8LDWQ-13 equivalent, key selection criteria include AEC-Q101 qualification, dual-channel SOT363 footprint compatibility, gate threshold voltage (0.8–1.5V), thermal resistance (360°C/W), and body diode forward voltage (1.2V @ 115mA).
Technical Context
This dual N-channel MOSFET integrates two matched enhancement-mode silicon devices in a single SOT363 package, sharing no internal connection between channels-each channel operates independently with isolated source, drain, and gate terminals. Its low RDS(ON) at 2.5V–4.5V gate drive enables efficient operation in 3.3V/5V logic-controlled automotive subsystems.
The device exhibits stable gate threshold (VGS(TH) shift < ±0.2V from −55°C to +150°C) and predictable on-resistance variation (RDS(ON) increases ~1.8× from 25°C to 125°C at VGS = 4.5V), supporting robust thermal design in space-constrained modules like infotainment power rails and small-motor drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - supports 24V automotive supply rails with 20% margin against transients |
| RDS(ON) @ 4.5VGS | 3Ω - enables ≤188mW conduction loss at 250mA, suitable for low-power load switching |
| ID (max, +25°C) | 250mA - defines continuous current capability per channel under standard PCB thermal conditions |
| Ciss | 48pF - limits gate drive power requirement and supports >1MHz switching in DC-DC controllers |
| tF | 13.6ns - ensures minimal switching transition time, reducing overlap losses in half-bridge configurations |
| VGS(TH) | 0.8–1.5V - guarantees turn-on with 1.8V/3.3V logic, compatible with modern microcontroller GPIO |
| TJ range | −55°C to +150°C - meets under-hood temperature requirements per AEC-Q101 stress test profile |

| 3 (D1) | Drain of Channel 1 | Switched high-side output node; connects to load or DC-DC switch node |
| 4 (D2) | Drain of Channel 2 | Independent high-side output; enables dual-load control without cross-talk |
| 5 (G2) | Gate of Channel 2 | Separate logic input; allows asynchronous or complementary control of second channel |
| 6 (S2) | Source of Channel 2 | Isolated return path; permits floating-source or high-side configuration with external bias |
Key Features

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 |
|---|---|---|---|
| DMN3026LSD-13 | 30V, 2.2Ω @ 4.5VGS, SOT26 package (larger footprint, higher ID = 300mA) | Higher current handling but lacks AEC-Q101 qualification; not PPAP-capable | Select when higher current (>250mA) is required and automotive qualification is not mandatory |
| NTJD4152PZ-1 | 20V, 2.8Ω @ 4.5VGS, SOT363, AEC-Q101 qualified, but lower VDSS | Not suitable for 24V rail transient immunity; limited to 12V systems only | Choose for cost-sensitive 12V automotive modules where 30V margin is unnecessary |
Compared with DMN33D8LDWQ-13, DMN3026LSD-13 offers higher current capacity but sacrifices automotive compliance, while NTJD4152PZ-1 trades voltage headroom for identical package and qualification-making DMN33D8LDWQ-13 the optimal balance of 30V rating, AEC-Q101 assurance, and SOT363 miniaturization.

FAQ
What is the maximum junction temperature and thermal resistance of DMN33D8LDWQ-13?
The DMN33D8LDWQ-13 has a maximum junction temperature of +150°C and a thermal resistance of 360°C/W (junction-to-ambient, mounted on 1"×1" FR-4 with 2oz copper). This value assumes standard PCB layout; actual thermal performance improves with enhanced copper pour or thermal vias.
Is DMN33D8LDWQ-13 suitable for high-side switching configurations?
Yes-each channel's source terminal is electrically isolated, enabling high-side switching when the source is biased above ground. However, gate drive must exceed source potential by ≥2.5V to ensure enhancement; external level-shifting or bootstrap circuitry may be required depending on topology.
Does DMN33D8LDWQ-13 include integrated body diodes, and what are their characteristics?
Each channel includes an intrinsic body diode with typical forward voltage of 1.2V at 115mA. These diodes support freewheeling in inductive loads and synchronous rectification, but are not rated for continuous reverse recovery at high dI/dt-external Schottky clamping is recommended in high-speed flyback applications.
How does the gate threshold voltage vary across temperature, and why does it matter for automotive use?
VGS(TH) decreases by ~0.5mV/°C from −55°C to +150°C, ranging 0.8–1.5V. This monotonic shift ensures consistent turn-on behavior across extreme ambient conditions, preventing unintended channel conduction during cold cranking or thermal soak-critical for fail-safe automotive subsystems.
