Product details
Overview
DMG3415UFY4-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in X2-DFN2015-3 package, rated for -16V V(BR)DSS, 39mΩ RDS(ON) @ VGS = -4.5V, and -2.5A ID at TA = +25°C. It serves as a low-side load switch or synchronous rectifier in compact DC-DC converters and backlight power rails.
For engineers reviewing the DMG3415UFY4-7 datasheet, DMG3415UFY4-7 pinout, DMG3415UFY4-7 application, or DMG3415UFY4-7 equivalent, key selection criteria include guaranteed RDS(ON) at low gate drive (-2.5V), AEC-Q101 qualification, 3kV ESD protection, and thermal resistance of 95°C/W under enhanced PCB layout.
Technical Context
This MOSFET employs a trench-gate process to achieve low on-resistance while maintaining fast switching (tD(on) = 79ns, tD(off) = 885ns) and low input capacitance (Ciss = 282pF). Its gate threshold voltage range (-0.3V to -1.0V) ensures reliable turn-on with logic-level controllers down to 2.5V supply.
The device integrates an internal gate protection diode and exhibits low output leakage (IDSS ≤ -1.0µA at VDS = -16V) and minimal reverse transfer capacitance (Crss = 38pF), supporting stable operation in high-frequency buck regulators and LED driver return paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| V(BR)DSS | -16V - Maximum drain-source blocking voltage before avalanche conduction begins |
| RDS(ON) | 39mΩ @ VGS = -4.5V - Confirmed on-resistance enabling <0.4W conduction loss at 2.5A |
| ID max | -2.5A @ TA = +25°C - Continuous current rating under standard FR-4 board conditions |
| Ciss | 282pF - Input capacitance determining gate drive energy and switching speed trade-off |
| Qg | 10nC - Total gate charge defining minimum drive strength required for 500kHz+ switching |
| RθJA | 95°C/W - Thermal resistance with 1-inch² copper pad, enabling 1.35W power dissipation |
| ESD Rating | 3kV HBM - On-chip protection eliminating need for external TVS in most portable designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG1012T | Higher RDS(ON): 60mΩ @ VGS = -4.5V; smaller 1.2×1.2mm X1-DFN1212-3 package | Lower power handling (0.5W PD); suited only for <1A loads | Select when board area is critical and current demand is ≤1A; not suitable for 2.5A DC-DC output stages |
| Si2301DDS | Lower V(BR)DSS: -20V; higher Qg: 15nC; same X2-DFN2015-3 footprint | Slower switching (tD(off) ≈ 1.2µs); less optimized for high-frequency sync rectification | Choose if higher breakdown margin is needed and switching frequency <300kHz; verify thermal derating at 2.5A |
Compared with DMG1012T and Si2301DDS, the DMG3415UFY4-7 delivers best-in-class RDS(ON)/Qg ratio for 2–3A loads in space-constrained, high-efficiency applications-especially where low gate drive voltage and AEC-Q101 compliance are mandatory.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The DMG3415UFY4-7 supports -2.2A continuous drain current at TA = +70°C with standard FR-4 PCB layout (2oz copper, minimum pad). This derating reflects thermal limits imposed by its 197°C/W junction-to-ambient resistance under baseline conditions.
Does this MOSFET require a gate resistor for stability?
A gate resistor of 3.0Ω is used in the datasheet's switching time test circuit to dampen ringing and ensure repeatable tD(on)/tD(off) measurements. For most 3.3V logic-driven applications, a 0–10Ω series resistor suffices; values >22Ω may degrade turn-on speed unnecessarily.
Is the exposed drain pad electrically connected to the drain terminal?
Yes-the exposed pad on the bottom of the X2-DFN2015-3 package is internally connected to the drain (Pin 3) and must be soldered to a PCB copper pour for both electrical functionality and thermal performance. No isolation or floating connection is permitted.
Can this part replace an N-channel MOSFET in high-side switching?
No-DMG3415UFY4-7 is a P-channel device intended for high-side or low-side switching where gate drive is referenced to source. Replacing an N-channel high-side switch would require redesigning the gate drive circuit to provide negative or floating bias, making it unsuitable as a drop-in substitute.
