Product details

Overview

DMG3415U-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in SOT23 package, rated for -20V V_DSS, 42.5mΩ R_DS(ON) at V_GS = -4.5V and -4.0A I_D, with AEC-Q101 qualification and 3kV ESD protection. It serves as a low-side load switch or synchronous rectifier in compact DC-DC converters.

For engineers reviewing the DMG3415U-13 datasheet, DMG3415U-13 pinout, DMG3415U-13 application, or DMG3415U-13 equivalent, key selection criteria include guaranteed R_DS(ON) at low gate drive (-1.8V to -4.5V), thermal resistance (R_θJA = 139°C/W), switching speed (t_F = 393ns), and automotive-grade reliability per AEC-Q101.

Technical Context

This MOSFET employs planar trench-gate technology optimized for low R_DS(ON) while maintaining fast turn-off (t_D(OFF) = 795ns) and low gate charge (Q_g = 9.1nC). Its gate threshold voltage (V_GS(TH) = -0.3 to -1.0V) enables reliable turn-on with logic-level controllers down to 1.8V supply rails.

The device integrates an ESD-protected structure (HBM 3kV) and exhibits low input capacitance (C_iss = 294pF) and reverse transfer capacitance (C_rss = 25pF), supporting high-frequency operation in buck converter topologies with minimal Miller effect.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	-20V - Maximum drain-source blocking voltage; supports 12V rail systems with margin.
R_DS(ON)	42.5mΩ @ V_GS = -4.5V, I_D = -4.0A - Enables <170mW conduction loss at full rated current.
Q_g	9.1nC - Low total gate charge reduces driver power and enables efficient 1–2MHz switching.
t_F	393ns - Fast fall time minimizes overlap loss in synchronous rectification.
R_θJA	139°C/W - Thermal performance validated on FR-4 PCB with minimum pad layout; limits max ambient to ~80°C at full power.
V_GS(TH)	-0.55V typical - Ensures robust turn-on with 1.8V/2.5V/3.3V GPIOs without level-shifting.
C_rss	25pF - Low reverse transfer capacitance suppresses dv/dt-induced false turn-on in high-side configurations.

Pinout & Package

Package: SOT23 - surface-mount plastic package with matte tin-annealed copper leadframe; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.008g.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Current return path for P-channel device	Connected to higher potential (e.g., input rail); forms common node with body diode anode.
2 (Gate)	Control terminal for channel formation	Driven negative relative to source; low C_iss (294pF) eases driving from microcontroller GPIOs.
3 (Drain)	Current output terminal	Connected to load or switching node; exposed drain pad improves thermal dissipation in PCB layout.

Key Features

Feature	Design Value
Low R_DS(ON) at 1.8V drive	71mΩ @ V_GS = -1.8V, I_D = -2.0A - enables direct control from battery-powered MCU outputs.
AEC-Q101 qualified	Qualified for automotive applications including engine control modules and body electronics - no derating required for temperature cycling or humidity exposure.
ESD protection	HBM rating of ±3kV - eliminates need for external ESD clamps in space-constrained portable designs.
Green RoHS compliance	Lead-free, halogen-free, antimony-free - meets IPC-1752A material declaration requirements for Tier 1 automotive suppliers.
Fast switching with low Q_gd	Q_gd = 1.7nC - reduces Miller plateau duration and improves controllability during hard-switching transitions.

Applications

Use Value: Ultra-low I_DSS (<1µA) prevents battery drain; 3kV ESD protection survives handling in unshielded factory environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar P-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMP2045U	R_DS(ON) = 45mΩ @ -4.5V (vs. 42.5mΩ); Q_g = 10.5nC (vs. 9.1nC); same SOT23 package	Slightly higher conduction loss and gate drive requirement; identical thermal footprint	Acceptable drop-in where <0.5mΩ R_DS(ON) margin is acceptable and layout reuse is critical.
AO3401	R_DS(ON) = 44mΩ @ -4.5V; V_GS(TH) = -0.7 to -1.3V (wider range); not AEC-Q101 qualified	Less predictable turn-on at low V_GS; unsuitable for automotive or mission-critical industrial use	Cost-sensitive consumer designs where AEC-Q101 is not mandated and tighter V_GS(TH) distribution is unnecessary.

Compared with DMP2045U and AO3401, DMG3415U-13 delivers lower gate charge and tighter V_GS(TH) distribution, enabling more deterministic timing in high-frequency synchronous rectifiers and better compatibility with 1.8V logic controllers - critical for battery-powered and automotive applications.

FAQ

What is the maximum continuous drain current for DMG3415U-13 at 70°C ambient?

The maximum continuous drain current is -3.5A at T_A = +70°C, derated from -4.0A at +25°C per the thermal resistance R_θJA = 139°C/W and power dissipation limit of 0.9W. This assumes standard FR-4 PCB with minimum recommended copper pad area.

Is DMG3415U-13 suitable for high-side switching configurations?

No - DMG3415U-13 is a P-channel MOSFET optimized for low-side switching. Its gate threshold voltage and lack of integrated level-shifting circuitry make it unsuitable for direct high-side use with ground-referenced controllers; external gate driver or charge pump is required for such topologies.

Does DMG3415U-13 include intrinsic body diode functionality?

Yes - it features an integrated body diode with forward voltage V_SD ≈ 0.85V at I_S = 1A and T_A = 25°C, enabling freewheeling current paths in buck converters and reverse-polarity protection when used as a load switch.

What is the meaning of "PPAP Capable" in the DMG3415U-13 datasheet?

"PPAP Capable" indicates Diodes Incorporated can provide Production Part Approval Process documentation (including PSW, control plans, and process capability studies) for DMG3415U-13 upon customer request - a requirement for Tier 1 automotive suppliers under AIAG standards.
