Product details
Overview
DMNH4015SSDQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET rated for 40V V(BR)DSS, 15mΩ RDS(on) at VGS = 10V, and 8.6A continuous drain current at TA = +25°C, qualified to AEC-Q101 for automotive engine management and body control systems.
For engineers reviewing the DMNH4015SSDQ-13 datasheet, DMNH4015SSDQ-13 pinout, DMNH4015SSDQ-13 application, or DMNH4015SSDQ-13 equivalent, key selection criteria include its +175°C junction rating, 100% unclamped inductive switching capability, low Qg (33nC at VGS = 10V), SO-8 package thermal performance, and AEC-Q101 PPAP support.
Technical Context
This dual MOSFET integrates two matched N-channel devices in a single SO-8 package with independent gate, source, and drain terminals per channel. Its design supports synchronous rectification and half-bridge topologies in DC-DC converters, where low RDS(on) and fast switching (tr = 10.5ns, tf = 5.7ns) reduce conduction and transition losses.
The device features thermally robust construction with RθJA = 75°C/W (with 1-inch² copper pad) and operates across -55°C to +175°C. Its 100% UIS-rated avalanche energy (EAS = 33mJ) ensures reliability under inductive load transients common in automotive power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 40V - Maximum blocking voltage before breakdown; defines safe operating range in 12V/24V automotive systems. |
| RDS(on) max | 15mΩ @ VGS = 10V - Low on-resistance minimizes I²R conduction loss at 12A load current. |
| ID (continuous) | 8.6A @ TA = +25°C - Sustained current capability with standard PCB layout; derates to 6.9A at +70°C. |
| Qg (total) | 33nC @ VGS = 10V - Gate charge determines driver strength requirement and switching speed in high-frequency converters. |
| TJ operating range | -55°C to +175°C - Enables deployment in under-hood environments without thermal derating penalties. |
| EAS | 33mJ @ L = 0.1mH - Confirmed avalanche energy handling supports robustness against inductive kickback in motor drives. |
| Package | SO-8 - Standard surface-mount footprint compatible with automated assembly and provides adequate thermal dissipation for <2W operation. |
Pinout & Package
Package: SO-8, molded plastic case with UL 94V-0 flammability rating, moisture sensitivity level 1, and tin-finished copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G1) | Gate of Channel 1 | Controls turn-on/turn-off of first N-MOSFET; requires ≥1V threshold and ≤±20V gate drive. |
| Pin 2 (S1) | Source of Channel 1 | Reference node for Channel 1; tied to local ground or floating node depending on topology. |
| Pin 3 (D1) | Drain of Channel 1 | High-side or low-side power path connection; handles up to 80A pulsed current (IDM). |
| Pin 4 (D2) | Drain of Channel 2 | Independent high-current output node for second channel; electrically isolated from D1. |
| Pin 5 (S2) | Source of Channel 2 | Reference node for Channel 2; may be connected to different potential than S1 in half-bridge configurations. |
| Pin 6 (G2) | Gate of Channel 2 | Separate gate input enables independent control of both channels for phase-shifted or complementary drive. |
| Pins 7 & 8 | Thermal Pad / Exposed Drain Tie | Internally connected to D1 and D2; must be soldered to PCB copper for thermal and electrical integrity. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3029LSD-13 | 30V V(BR)DSS, 2.9mΩ RDS(on) @ 10V, SO-8, AEC-Q101 | Lower voltage rating limits use to 12V-only systems; superior RDS(on) benefits low-voltage, high-current apps. | Select when system bus voltage ≤30V and ultra-low conduction loss is prioritized over 40V margin. |

FAQ
What is the maximum continuous drain current for DMNH4015SSDQ-13 at +70°C ambient?
The maximum continuous drain current is 6.9A per channel at TA = +70°C with standard FR-4 PCB layout (2oz copper, minimum pad). This value is derived from thermal derating curves in the datasheet and assumes steady-state conduction without pulse duty-cycle relief.
Is DMNH4015SSDQ-13 suitable for synchronous rectification in a 400kHz buck converter?
Yes-its 33nC total gate charge (at VGS = 10V), 10.5ns rise time, and 5.7ns fall time enable efficient operation at 400kHz. The SO-8 package's thermal resistance (RθJA = 75°C/W with 1-inch² copper) supports this frequency under typical load conditions.
How is the exposed thermal pad (Pins 7 & 8) connected internally?
Pins 7 and 8 are internally tied to both drains (D1 and D2) and serve as the primary thermal and electrical connection point for the MOSFET die. They must be soldered to a large PCB copper area to achieve specified RθJA and ensure current-carrying capability.
Does DMNH4015SSDQ-13 require external gate resistors for automotive EMI compliance?
While not mandatory, a 5–10Ω series gate resistor is recommended to dampen ringing caused by parasitic inductance in high-di/dt automotive environments. This improves EMI performance without significantly impacting switching speed, given the device's low Qg and fast intrinsic response.
