Product details

Overview

DMG4466SSSL-13 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SO-8 package, rated for 30 V V_DS, 23 mΩ R_DS(ON) @ 10 V_GS, and 10 A continuous drain current at 25°C. It delivers low conduction loss and fast switching (t_D(on) = 2.9 ns, t_D(off) = 14.6 ns) for high-efficiency DC-DC converters and backlighting power stages.

For engineers reviewing the DMG4466SSSL-13 datasheet, DMG4466SSSL-13 pinout, DMG4466SSSL-13 application, or DMG4466SSSL-13 equivalent, key selection criteria include verified R_DS(ON) at 4.5 V_GS (33 mΩ), AEC-Q101 qualification, SO-8 thermal resistance (R_θJA = 88.4°C/W), and gate charge (Q_g = 10.5 nC @ 10 V_GS) for synchronous buck control.

Technical Context

This MOSFET employs a planar trench-gate structure optimized for low R_DS(ON) while maintaining robust switching performance. Its gate threshold voltage (V_GS(th) = 1.0–2.4 V) enables reliable turn-on with standard logic-level drivers, and its low input capacitance (C_iss = 478.9 pF) reduces drive power requirements.

The device integrates a body diode with V_SD = 0.69 V @ 1 A and supports repetitive avalanche energy (E_AR = 12.8 mJ), enabling operation in inductive switching circuits without external snubbers. Thermal design is supported by a 0.074 g mass and JEDEC-standard SO-8 pad layout recommendations.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3026LSD-13	R_DS(ON) = 26 mΩ @ 10 V_GS; higher C_iss (540 pF); same SO-8 package	Marginally higher conduction loss but identical footprint for drop-in replacement in space-constrained boards	Select when board layout reuse is prioritized over minimal R_DS(ON) improvement
SI2306DS-T1-GE3	R_DS(ON) = 28 mΩ @ 10 V_GS; lower I_D (6.2 A); SOT-23 package	Not pin-compatible; suitable only for lower-current (<6 A), space-limited applications where SO-8 is prohibitive	Choose for cost-sensitive, low-power designs where thermal budget allows smaller package

Compared with DMN3026LSD-13 and SI2306DS-T1-GE3, DMG4466SSSL-13 offers the lowest R_DS(ON) and highest continuous current in SO-8, making it optimal for thermally demanding 8–10 A power stages where layout compatibility and AEC-Q101 compliance are required.

FAQ

What is the maximum junction temperature for continuous operation?

The DMG4466SSSL-13 has a specified operating junction temperature range of –55°C to +150°C. For continuous operation under rated current, thermal design must ensure T_J remains ≤150°C, typically requiring heatsinking or airflow when dissipating >0.5 W in ambient >70°C environments.

Is this MOSFET suitable for synchronous rectification in a 48 V input buck converter?

No - the 30 V V_DS rating makes DMG4466SSSL-13 unsuitable for 48 V bus applications. It is designed for ≤30 V systems such as 12 V automotive, 24 V industrial, or 5/3.3 V point-of-load converters where V_DS stress remains within 80% of rating.

Does the SO-8 package include an exposed thermal pad?

Yes - the SO-8 package features an exposed drain paddle (pins 3, 4, 5, 7, 8) that must be soldered to a PCB thermal pad per AP02001 recommended layout. This pad is electrically connected to drain and improves R_θJA by up to 30% versus non-thermal SO-8 variants.

Can this MOSFET replace a P-channel device in high-side switching?

No - DMG4466SSSL-13 is an N-channel MOSFET requiring gate voltage ≥ V_DS for full enhancement. High-side switching would necessitate a bootstrap or charge-pump gate driver, whereas a P-channel device enables simpler direct GPIO control with logic-low turn-on.
