Product details
Overview
DMN4027SSS-13 from Diodes Incorporated is a 40V N-channel enhancement-mode MOSFET in SO-8 package, rated for 8.0A continuous drain current at VGS = 10V, with RDS(on) = 27 mΩ (typ. 17 mΩ), qualified to AEC-Q101 for automotive reliability, and used in DC-DC converters and motor control circuits.
For engineers reviewing the DMN4027SSS-13 datasheet, DMN4027SSS-13 pinout, DMN4027SSS-13 application, or DMN4027SSS-13 equivalent, key selection criteria include on-resistance at 4.5V gate drive, body diode recovery performance (trr = 12.2 ns), thermal resistance (RθJA = 44.5 °C/W on 25 mm × 25 mm PCB), and SO-8 lead-frame construction with matte tin finish.
Technical Context
This MOSFET operates as a low-side switching element in synchronous buck regulators and H-bridge motor drivers, leveraging its fast switching speed (tD(off) = 15.4 ns) and low gate charge (Qg = 12.9 nC at VGS = 10V) to minimize conduction and switching losses.
Its design integrates a robust body diode (VSD = 0.85–1.1 V at IS = 7A) with low reverse recovery charge (Qrr = 5.4 nC), enabling efficient freewheeling in inductive loads without external Schottky supplementation in many mid-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 40 V - Maximum blocking voltage compatible with 24V automotive and industrial bus systems. |
| RDS(on) | 27 mΩ @ VGS = 10V - Enables ≤2.1 W conduction loss at 9.2A peak in continuous operation. |
| ID | 8.0 A @ TA = 25°C - Supports ≥6.5A derated current in 70°C ambient with standard PCB layout. |
| Qg | 12.9 nC @ VGS = 10V - Allows efficient gate driving with <100 mA peak current from typical PWM controllers. |
| trr | 12.2 ns - Limits voltage overshoot and EMI during body-diode commutation in hard-switched topologies. |
| RθJA | 44.5 °C/W - Delivers 2.8 W power dissipation capability on 25 mm × 25 mm 1 oz copper FR4 board. |
| VGS(th) | 1.0–3.0 V - Ensures reliable turn-on with 3.3V or 5V logic-level gate drivers. |
Pinout & Package
Package: SO-8 (Surface-mount, 8-lead, gull-wing leads; case outline per Diodes Inc. drawing DS32103, 4.80–5.00 mm width, 3.80–4.00 mm length, 1.35–1.75 mm height).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5 | Drain (internally connected) | High-current output node; requires thermal pad connection to PCB copper for heat dissipation. |
| 6 | Gate | Control input; low capacitance (Ciss = 604 pF) enables fast edge rates with minimal driver effort. |
| 7, 8 | Source | Power return path; dual pins reduce source inductance and improve switching stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 4.5V | 47 mΩ - Enables direct compatibility with 5V microcontroller GPIOs without level-shifting. |
| AEC-Q101 qualification | Qualified for automotive powertrain and chassis applications requiring high-reliability stress testing. |
| Green RoHS-compliant packaging | Molded plastic with halogen-free, antimony-free compound meeting UL 94V-0 flammability rating. |
| Fast body diode recovery | trr = 12.2 ns and Qrr = 5.4 nC - Reduces switching loss and ringing in synchronous rectification. |
Applications
| Motor Control | DC-DC Converters |
|---|---|
Use Scenario: Driving brushed DC motors in automotive seat adjusters and HVAC actuators. IC Role / Device Role / Timing Role: Low-side switch in half-bridge configuration, handling bidirectional current up to 6.1A at 12V supply. Use Value: Low RDS(on) minimizes I²R heating during stall conditions; fast turn-off limits shoot-through risk during PWM dead-time. | Use Scenario: Synchronous rectifier in 12V-to-5V/3.3V buck converters for infotainment head units. IC Role / Device Role / Timing Role: Secondary-side power switch replacing Schottky diode to improve efficiency above 2A load. Use Value: Body diode trr < 13 ns prevents voltage spikes during light-load discontinuous conduction mode transitions. |
| Backlighting | Power Management Functions |
Use Scenario: LED current regulation in LCD backlight drivers for commercial displays. IC Role / Device Role / Timing Role: PWM-controlled current sink for strings of 3–5 white LEDs at 20–100 mA per channel. Use Value: Low gate charge (Qg = 6.3 nC @ 4.5V) allows clean 10–20 kHz dimming without gate-drive distortion. | Use Scenario: Load switch for USB-powered peripherals in industrial HMIs. IC Role / Device Role / Timing Role: Controlled power enable/disconnect with soft-start via gate resistor network. Use Value: Gate threshold range (1.0–3.0 V) ensures predictable turn-on across temperature and process variation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3027LSD-13 | 30V VDS, lower RDS(on) (22 mΩ @ 10V), same SO-8 package | Not suitable for 40V bus systems; limited to ≤24V designs | Select when system voltage is capped at 24V and lower conduction loss is prioritized over voltage margin. |
| IRF7470PBF | 40V VDS, higher RDS(on) (32 mΩ @ 10V), TO-252 package | Requires larger PCB footprint and different thermal management strategy | Choose only if SO-8 mounting is incompatible and higher thermal resistance (RθJA ≈ 62 °C/W) is acceptable. |
Compared with DMN3027LSD-13 and IRF7470PBF, DMN4027SSS-13 uniquely balances 40V rating, SO-8 compactness, and sub-30 mΩ on-resistance-making it optimal for space-constrained 24V/36V automotive modules where thermal density and gate drive simplicity are critical.

FAQ
Is DMN4027SSS-13 still in active production?
No-DMN4027SSS-13 is marked "ADVANCE INFORMATION DISCONTINUED" in its official datasheet (DS32103 Rev 2–3, May 2013). While legacy stock may be available through authorized channels, Diodes Incorporated no longer manufactures this part. Aetrix Electronics offers full traceability and remaining inventory verification for last-time buys.
What is the maximum safe operating junction temperature for DMN4027SSS-13?
The absolute maximum junction temperature is 150°C, as specified in the Thermal Characteristics table. Derating begins at 25°C ambient, with linear reduction of power dissipation above that point-e.g., at 70°C ambient, maximum continuous power drops to 2.8 W (per note 4 in datasheet).
Can DMN4027SSS-13 be used with 3.3V gate drive?
Yes-its gate threshold voltage range (1.0–3.0 V) guarantees turn-on with 3.3V logic, though RDS(on) rises to 47 mΩ at VGS = 4.5V. For optimal efficiency, pair with a gate driver capable of 5V or 10V swing; at 3.3V, verify worst-case ID does not exceed 4.2A (body diode limit) under pulsed conditions.
Does DMN4027SSS-13 have integrated ESD protection?
No-this MOSFET lacks on-die ESD protection structures. External TVS diodes or series resistors are recommended on gate traces in environments with >2 kV HBM exposure risk. Its gate oxide is rated for ±20V VGS, but transient overvoltage beyond ±16V violates AEC-Q101 stress limits.
