Product details
Overview
DMNH4015SSD-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in SO-8 package, rated for 40V VDSS, 15 mΩ RDS(ON) @ 10VGS, and 8.6A continuous drain current at +25°C. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters and power management circuits operating up to +175°C junction temperature.
For engineers reviewing the DMNH4015SSD-13 datasheet, DMNH4015SSD-13 pinout, DMNH4015SSD-13 application, or DMNH4015SSD-13 equivalent, key selection criteria include its dual-channel SO-8 layout, AEC-Q101 qualification, 100% lead-free "Green" construction, and validated performance under pulsed and steady-state thermal conditions per J-STD-020 Level 1.
Technical Context
This dual MOSFET integrates two matched N-channel silicon devices in a single SO-8 package with independent gate, source, and drain terminals for each channel. Its design emphasizes low RDS(ON) (15 mΩ @ 10VGS) and low input capacitance (1938 pF), enabling high-frequency synchronous rectification and compact power stage layouts.
The device supports operation across -55°C to +175°C junction temperature range and meets AEC-Q101 stress testing requirements for automotive-grade reliability. Thermal resistance is specified as 75°C/W (RθJA, 1-inch² copper) and 13°C/W (RθJC), confirming suitability for thermally constrained PCB designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage before avalanche; defines safe operating range in 12–24V bus applications. |
| RDS(ON) @ 10VGS | 15 mΩ - Low conduction loss enabling <1.5W dissipation at 8.6A, critical for thermally limited DC-DC stages. |
| ID (continuous, +25°C) | 8.6 A - Steady-state current capability per channel; supports dual-phase buck converter legs or redundant load switches. |
| QG @ 10VGS | 33 nC - Gate charge value directly impacts driver sizing and switching loss; enables efficient operation at >500 kHz. |
| TJ max | +175°C - High-temperature rating allows deployment in under-hood automotive or industrial motor control enclosures without derating. |
| Ciss | 1938 pF - Input capacitance determines Miller effect and gate drive energy; optimized for stable PWM control with standard gate drivers. |

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 |
|---|---|---|---|
| DMN3025LSD-13 | 30V VDSS, 2.5 mΩ RDS(ON) @ 10VGS, SO-8, same AEC-Q101 qualification | Lower voltage rating limits use to ≤24V systems; superior RDS(ON) reduces conduction loss by 83% at 12V bus | Select when system bus voltage is ≤30V and ultra-low on-resistance is prioritized over 40V headroom. |
| SI6926ADQ-T1-GE3 | 40V VDSS, 18 mΩ RDS(ON) @ 10VGS, SO-8, no AEC-Q101 documentation confirmed | Higher RDS(ON) increases conduction loss by ~20%; lacks automotive qualification documentation | Acceptable for industrial non-automotive applications where AEC-Q101 is not required and 3 mΩ penalty is tolerable. |
Compared with DMNH4015SSD-13, DMN3025LSD-13 offers significantly lower RDS(ON) but sacrifices 10V of voltage margin, while SI6926ADQ-T1-GE3 matches voltage rating but lacks documented automotive qualification and exhibits higher conduction loss-making DMNH4015SSD-13 optimal for 40V-rated, AEC-Q101–compliant designs requiring balanced performance.

FAQ
What is the maximum continuous drain current per channel at +70°C ambient?
The DMNH4015SSD-13 supports 6.9A continuous drain current per channel at +70°C ambient temperature under steady-state conditions with recommended PCB layout (2 oz copper, minimum pad area). This rating reflects thermal derating from the +25°C value of 8.6A and assumes proper thermal pad soldering to maintain RθJA = 75°C/W.
Does this part support logic-level gate drive at 3.3V?
No-the gate threshold voltage (VGS(TH)) ranges from 1V to 3V, but RDS(ON) is only guaranteed at 4.5V and 10V gate drive. At 3.3V, the device will conduct but with significantly elevated on-resistance (>50 mΩ), increasing conduction loss beyond typical design margins. Use with 3.3V controllers requires verification of load current and thermal budget.
How is the thermal pad (pins 7 and 8) electrically connected?
Pins 7 and 8 are internally connected to both drain terminals (D1 and D2) and serve as the primary thermal path. They must be soldered to a dedicated PCB copper pour tied to the system ground plane or low-impedance drain return. No isolation or floating connection is permitted-this connection is essential to achieve the specified RθJC = 13°C/W and prevent thermal runaway.
Is there a qualified automotive variant of this part?
Yes-the DMNH4015SSDQ is the AEC-Q101 qualified automotive variant, documented in a separate datasheet (DS38105Q). While the DMNH4015SSD-13 itself is AEC-Q101 qualified per its datasheet, the "Q" suffix denotes the fully automotive-grade version with extended test reporting and PPAP documentation support for Tier 1 suppliers.
