Product details
Overview
DMN3112SSS-13 from Diodes Incorporated is a single N-channel enhancement-mode MOSFET in SOP-8L package, rated for 30V VDS, 57 mΩ RDS(on) at VGS = 10 V, and 6.0 A continuous drain current at TA = +25°C. It delivers low gate threshold (1–2.2 V), fast switching, and AEC-Q101 qualification for automotive-grade reliability in DC-DC converter power stages.
For engineers reviewing the DMN3112SSS-13 datasheet, DMN3112SSS-13 pinout, DMN3112SSS-13 application, or DMN3112SSS-13 equivalent, key selection criteria include RDS(on) @ 4.5 V (112 mΩ), thermal resistance (50 °C/W), input capacitance (268 pF), and SOP-8L footprint compatibility with space-constrained power management layouts.
Technical Context
This MOSFET operates as a synchronous rectifier or high-side/low-side switch in buck and boost converters, leveraging its low 1.0–2.2 V gate threshold to ensure robust turn-on with 3.3 V or 5 V logic-level drive. Its 268 pF input capacitance and 50 pF reverse transfer capacitance support clean gate drive and reduced Miller-induced shoot-through risk.
The device integrates an intrinsic body diode with 0.5–1.2 V forward voltage at 2.1 A, enabling freewheeling operation without external diodes in non-synchronous topologies. Thermal design is anchored to its 50 °C/W junction-to-ambient rating on standard 2 oz copper pad layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | Lower RDS(on) (25 mΩ @ 10 V), same SOP-8L, higher Ciss (490 pF) | Better conduction loss but demands stronger gate driver for 500 kHz+ switching | Prefer when thermal budget is tight and gate drive capability supports higher Ciss |
| SI2302DS-T1-GE3 | Higher RDS(on) (90 mΩ @ 4.5 V), SOT-23 package, lower ID (2.6 A) | Limited to sub-2 A loads; unsuitable for 6 A DC-DC primary switches | Select only for space-constrained, low-current bias or signal-switching roles |
Compared with DMN3112SSS-13, DMN3025LSD-13 offers superior conduction efficiency but increases gate drive demand, while SI2302DS-T1-GE3 sacrifices current capacity and thermal headroom for footprint reduction-neither is pin-compatible, requiring layout revision.

FAQ
Is DMN3112SSS-13 suitable for 3.3 V logic-level gate drive?
Yes. With a gate threshold voltage range of 1.0–2.2 V and guaranteed RDS(on) of 112 mΩ at VGS = 4.5 V, it fully enhances using standard 3.3 V microcontroller outputs. Gate charge is 7.5 nC, compatible with most GPIOs driving ≤100 pF load.
What is the maximum continuous power dissipation for DMN3112SSS-13 on a standard PCB?
At TA = +25°C with a 2 oz copper pad layout, the device supports 2.5 W continuous power dissipation, corresponding to RθJA = 50 °C/W. Derating is required above +25°C ambient; at +70°C, max power drops to ~1.25 W.
Does DMN3112SSS-13 include an integrated ESD protection diode?
No. The device does not integrate dedicated ESD protection structures. Its gate oxide withstands ±20 V VGS, but external TVS or RC snubbers are recommended for board-level ESD immunity per IEC 61000-4-2 Level 4 (±15 kV air).
Can DMN3112SSS-13 be used in synchronous rectification for isolated DC-DC converters?
Yes. Its low RDS(on), fast switching (ton/toff < 20 ns typical), and body diode recovery characteristics make it suitable for secondary-side synchronous rectification in flyback and forward converters up to 500 kHz, provided gate timing avoids cross-conduction.
