Product details
Overview
DMN4034SSS-13 from Diodes Incorporated is a 40V N-channel enhancement-mode MOSFET in SO-8 package, rated for 7.2A continuous drain current at VGS = 10V, with RDS(on) = 34 mΩ and fast switching (tD(off) = 14 ns). It is AEC-Q101 qualified and used in DC-DC converters, motor control, backlighting, and power management circuits requiring low conduction loss and reliable unclamped inductive switching.
For engineers reviewing the DMN4034SSS-13 datasheet, DMN4034SSS-13 pinout, DMN4034SSS-13 application, or DMN4034SSS-13 equivalent, key selection criteria include its 40V VDS, 34 mΩ on-resistance at 10V gate drive, SO-8 thermal performance (RθJA = 80 °C/W), AEC-Q101 qualification, and 100% production-tested UIS capability.
Technical Context
This MOSFET employs planar silicon technology optimized for low RDS(on) while maintaining robust avalanche ruggedness (EAS = 27 mJ) and fast turn-off (tD(off) = 14 ns, tf = 6 ns). Its gate charge profile (Qg = 10–18 nC at VGS = 10V) supports efficient high-frequency switching in synchronous buck stages.
The device integrates a body diode with VSD = 0.87–1.1 V at IS = 6A and trr = 11.9 ns, enabling moderate-speed freewheeling in non-synchronous topologies. Thermal design is supported by RθJL = 37 °C/W to the lead and validated SO-8 footprint compatibility with 1 oz copper FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage in high-side or low-side switch configurations without breakdown. |
| RDS(on) | 34 mΩ @ VGS = 10V, ID = 6A - Enables ≤0.5 W conduction loss at 7.2A, critical for thermally constrained DC-DC designs. |
| ID (continuous) | 7.2 A @ TA = 25°C - Supports medium-power load switching with derated 5.4 A at 70°C ambient on standard PCB. |
| EAS | 27 mJ - Confirmed single-pulse avalanche energy rating ensures reliability under inductive load transients (L = 100 µH, VDD = 40V). |
| tD(off) | 14 ns - Short turn-off delay enables stable operation up to ~5 MHz in hard-switched applications with minimal dead-time sensitivity. |
| Qg | 10–18 nC @ VGS = 10V - Gate drive power requirement of ~180 µW per MHz at 10V swing, compatible with standard gate drivers. |
| VGS(th) | 1.0–3.0 V - Ensures clean turn-on with 3.3V or 5V logic-level gate signals, avoiding partial enhancement in digital control systems. |
Pinout & Package
Package: SO-8 (Surface-mount, 8-lead small-outline integrated circuit), 5.0 mm × 4.0 mm footprint, 1.75 mm max height, matte tin-plated copper leads, RoHS-compliant green molding compound (UL 94V-0).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | Drain (internally connected) | High-current output node; electrically tied to exposed pad - must be soldered to large copper pour for thermal and current handling. |
| 6 | Gate | Control input; requires <18 nC total charge to fully enhance; sensitive to ESD (±20 V absolute max). |
| 7, 8 | Source | Reference node for gate drive and current sensing; connects to ground or low-side return path in buck/boost topologies. |
Key Features
| Feature | Design Value |
|---|---|
| 100% production UIS tested | Guarantees avalanche survivability in real-world inductive switching events without screening failure. |
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications including engine control modules and lighting drivers. |
| Low RDS(on) × Qg figure-of-merit | ~0.6 nC·Ω - Balances conduction and switching losses for high-efficiency 1–3 MHz DC-DC converters. |
| Body diode with trr = 11.9 ns | Enables use in non-synchronous flyback or buck converters without external Schottky catch diode in cost-sensitive designs. |
| Green RoHS-compliant construction | No halogens or antimony; meets JEDEC J-STD-020 moisture sensitivity Level 1 for reflow compatibility. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3029LSD-13 | 30V VDS, 2.9 mΩ RDS(on) @ 10V, SO-8 - lower voltage rating but significantly lower on-resistance. | Not suitable for 40V bus applications; preferred in 24V systems where ultra-low conduction loss dominates. | Select when system VIN ≤ 28V and efficiency at high load current is prioritized over voltage margin. |
| SI4436DY-T1-GE3 | 40V VDS, 38 mΩ RDS(on) @ 10V, SO-8 - slightly higher on-resistance, no AEC-Q101 qualification. | Lacks automotive qualification; suited for commercial-grade power supplies and consumer electronics only. | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not required and 4 mΩ penalty is acceptable. |
Compared with DMN3029LSD-13 and SI4436DY-T1-GE3, DMN4034SSS-13 uniquely delivers 40V rating, AEC-Q101 compliance, and production-tested UIS in a single SO-8 package - making it the only option among the three qualified for automotive 12V/24V power distribution and harsh-environment industrial control.

FAQ
Is DMN4034SSS-13 suitable for 5V gate drive applications?
Yes - its VGS(th) range (1.0–3.0 V) and RDS(on) = 59 mΩ @ VGS = 4.5V ensure full enhancement with standard 5V logic outputs. The device delivers 5.5A continuous current under these conditions, supporting direct microcontroller or gate-driver interfacing without level shifting.
What is the maximum junction temperature during continuous operation?
The absolute maximum junction temperature is 150°C. Under typical SO-8 mounting on 25 mm × 25 mm 1 oz FR4 PCB, the device reaches thermal equilibrium at 150°C with 2.8 W dissipation (PD = 2.8 W at TA = 70°C), corresponding to ~5.4 A at RDS(on) = 59 mΩ.
Does DMN4034SSS-13 include an integrated Schottky diode?
No - it uses a standard silicon body diode with VSD = 0.87–1.1 V and trr = 11.9 ns. While not a Schottky, this diode is characterized and production-tested for freewheeling in non-synchronous topologies; external Schottky placement remains optional for higher efficiency.
How is the SO-8 thermal performance validated?
Thermal resistance values (RθJA = 80 °C/W, RθJL = 37 °C/W) are measured per JEDEC JESD51-2 and JESD51-14 standards on 25 mm × 25 mm FR4 PCB with 1 oz copper. The exposed drain pad is soldered to internal/external copper planes, and measurements reflect steady-state conditions at t ≤ 10 sec.
