Product details
Overview
DMG8880LSS from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in SO-8 package, rated for 11.6A continuous drain current at 25°C, with RDS(on) of 7.0 mΩ at VGS = 10V and 9.6 mΩ at VGS = 4.5V, designed for high-efficiency DC-DC power conversion stages in automotive body control modules.
For engineers reviewing the DMG8880LSS datasheet, DMG8880LSS pinout, DMG8880LSS application, or DMG8880LSS equivalent, key selection criteria include low gate charge (27.6 nC at 10V), fast switching (tD(on) = 7.04 ns), AEC-Q101 qualification, SO-8 thermal performance (RθJA = 87°C/W), and 30V VDSS rating for 12V system compatibility.
Technical Context
This MOSFET operates as a synchronous rectifier or high-side switch in buck converters and load switches, leveraging its low RDS(on) and optimized gate charge to minimize conduction and switching losses. Its 1.0–2.0V gate threshold enables robust drive from 3.3V and 5V logic controllers.
The device features integrated body diode with VSD = 0.7V at IS = 2.1A and exhibits stable RDS(on) over temperature (±20% variation from −55°C to 150°C), supporting operation in under-hood automotive environments without derating penalties.

| RDS(on) @ VGS = 10V | 7.0 mΩ - Enables ≤0.85W conduction loss at 11.6A, reducing heatsink requirements |
| RDS(on) @ VGS = 4.5V | 9.6 mΩ - Ensures reliable turn-on with standard 4.5V logic-level gate drivers |
| Qg @ 10V | 27.6 nC - Limits gate drive power and enables >1 MHz switching in compact converters |
| tD(on) | 7.04 ns - Reduces dead-time losses in synchronous rectification topologies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG4406LSS | Higher RDS(on) (12 mΩ @ 10V), lower Qg (17 nC), same SO-8 package | Better suited for ultra-fast switching where conduction loss is secondary to gate drive power | Select when prioritizing <10 ns tD(on) and lower gate energy over peak current capability |
| NTMFS4C09NT1G | Lower RDS(on) (4.5 mΩ @ 10V), higher ID (17.5A), PowerSO-8 package with larger thermal pad | Requires revised PCB layout due to different pinout and thermal pad geometry | Choose for higher current density designs needing <0.5W conduction loss at 15A, accepting re-layout effort |
Compared with DMG4406LSS, DMG8880LSS delivers 42% lower RDS(on) at cost of +62% Qg; versus NTMFS4C09NT1G, it offers identical footprint compatibility but trades 32% higher conduction loss for proven AEC-Q101 qualification and simplified sourcing.

FAQ
Is DMG8880LSS suitable for high-frequency switching above 1 MHz?
Yes - with tD(on) = 7.04 ns, tr = 17.52 ns, and Qg = 27.6 nC at 10V, the DMG8880LSS supports efficient operation up to 2 MHz in well-designed gate-drive circuits using low-impedance paths and proper PCB layout. Thermal limits (1.43 W PD) constrain sustained duty cycle at such frequencies.
What is the maximum allowable gate-source voltage during transient conditions?
The absolute maximum VGS is ±20V per datasheet. During transient events such as ESD or ringing, clamping to ±15V is recommended via gate resistors and Zener diodes. Exceeding ±20V risks permanent oxide damage, especially at elevated temperatures.
Does DMG8880LSS require a heatsink in SO-8 mounting?
No external heatsink is required for ≤1.43W power dissipation on FR-4 PCB with Diodes' minimum recommended pad layout (including thermal vias to inner ground planes). At full 11.6A continuous current, board-level copper area and airflow determine whether ambient derating applies - RθJA = 87°C/W assumes no added heatsink.
Can DMG8880LSS be used in linear regulator applications?
No - it is not characterized or qualified for linear mode operation. The Safe Operating Area (SOA) curve shows limited single-pulse capability at low VDS/high ID, and prolonged linear operation risks thermal runaway due to positive temperature coefficient of RDS(on). It is intended strictly for switching applications.
