Product details
Overview
DMN10H170SFG-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in POWERDI®3333 package, rated for 100V V(BR)DSS, 122mΩ RDS(ON) @ VGS = 10V, and 2.9A continuous drain current at TA = +25°C. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters and LED backlighting circuits.
For engineers reviewing the DMN10H170SFG-7 datasheet, DMN10H170SFG-7 pinout, DMN10H170SFG-7 application, or DMN10H170SFG-7 equivalent, key selection criteria include its 100V breakdown voltage, 122mΩ on-resistance at 10V gate drive, AEC-Q101 qualification, thermal resistance of 137°C/W (steady-state), and compact POWERDI3333 footprint occupying only 33% of SO-8 board area.
Technical Context
This MOSFET employs planar silicon process technology optimized for low RDS(ON) while maintaining robust UIS capability (20mJ avalanche energy). Its gate threshold voltage range (1.0–3.0V) supports TTL- and CMOS-level drive compatibility in power management stages.
The device features a fully integrated body diode with 0.7–1.0V forward voltage at 3.3A, and dynamic parameters including 870.7pF input capacitance, 24.6pF reverse transfer capacitance, and 14.9nC total gate charge at VGS = 10V - enabling efficient operation in 300kHz–1MHz switching regulators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| V(BR)DSS | 100V - withstands up to 100V drain-source blocking voltage before avalanche onset, suitable for 48V bus and automotive 36V systems. |
| RDS(ON) max | 122mΩ @ VGS = 10V - limits I²R conduction loss to ≤1.04W at 3.3A, critical for thermally constrained DC-DC designs. |
| ID max (TA = +25°C) | 2.9A - maximum continuous drain current under standard PCB mounting (2oz copper, minimal pad), defining safe operating area. |
| Qg (VGS = 10V) | 14.9nC - determines gate driver power requirement and switching transition time in hard-switched topologies. |
| RθJA (steady-state) | 137°C/W - junction-to-ambient thermal resistance on FR-4 with minimum recommended pad layout, used to calculate max junction temperature. |
| Avalanche Energy EAR | 20mJ - validated unclamped inductive switching capability ensures reliability during load dump or inductive turn-off events. |
| VGS(th) | 1.0–3.0V - gate threshold range enables direct interface with 3.3V microcontrollers without level-shifting circuitry. |
Pinout & Package
Package: POWERDI®3333 - surface-mount, thermally enhanced plastic package with exposed drain pad; dimensions 3.30 × 3.30 × 0.80 mm; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | Control terminal; requires ≤±20V gate-source voltage; 1.1Ω gate resistance minimizes ringing in high-dV/dt environments. |
| Pins 2–4 (S) | Source | Common return path for drain current and gate drive reference; electrically tied to internal substrate connection. |
| Pins 5–8 (D) | Drain | Main power output terminal; connected to exposed copper pad on bottom for thermal conduction to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| 100% production UIS tested | Guarantees 20mJ avalanche energy handling without derating - eliminates need for external snubbers in flyback or boost converters. |
| POWERDI3333 package | Reduces board area by 67% vs SO-8 while delivering 7.0°C/W junction-to-case thermal resistance - enables higher power density in space-constrained modules. |
| Low RDS(ON) @ 4.5V | 133mΩ at VGS = 4.5V - supports efficient operation directly from 5V logic rails or buck converter outputs without gate boosting. |
| AEC-Q101 qualified | Validated for automotive power management applications including infotainment supplies and body control modules. |
| Halogen- and antimony-free | <900ppm Br, <900ppm Cl, <1000ppm Sb - meets global environmental compliance requirements for consumer and industrial end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3020LSD-13 | 30V V(BR)DSS, 20mΩ RDS(ON) @ 4.5V, SOT-23-6 package | Lower voltage rating; unsuitable for >40V bus applications but offers lower on-resistance in 3.3V/5V logic-driven loads. | Select when operating below 30V and prioritizing ultra-low RDS(ON) over voltage margin. |
| DMN601DWK-7 | 60V V(BR)DSS, 115mΩ RDS(ON) @ 10V, SOT-363 package | Smaller 3-pin SOT-363 footprint; lacks AEC-Q101 qualification and has lower UIS rating (12mJ). | Choose for space-constrained consumer electronics where automotive qualification is not required. |
Compared with DMN3020LSD-13 and DMN601DWK-7, DMN10H170SFG-7 uniquely combines 100V rating, AEC-Q101 qualification, and POWERDI3333 thermal performance - making it the only option among the three suitable for 48V industrial power supplies and automotive 12V/24V systems with load dump immunity.

FAQ
What is the maximum allowable junction temperature for DMN10H170SFG-7?
The absolute maximum junction temperature is +150°C, as specified in the Thermal Characteristics table. Operation above this limit risks permanent parametric shift or catastrophic failure. Derating is required above +70°C ambient due to reduced power dissipation (PD drops from 0.94W to 0.6W between 25°C and 70°C ambient).
Can DMN10H170SFG-7 be used in linear (analog) mode operation?
No - this MOSFET is optimized for switching operation only. Its Safe Operating Area (SOA) is not characterized for linear mode, and prolonged operation in the ohmic region may cause localized thermal runaway due to positive temperature coefficient of RDS(ON) and limited thermal mass in the POWERDI3333 package.
Is the POWERDI3333 package lead-free and RoHS compliant?
Yes - DMN10H170SFG-7 is fully RoHS compliant (2011/65/EU) with no purposely added lead, and qualifies as "Green" per Diodes' definition: <900ppm bromine, <900ppm chlorine, and <1000ppm antimony compounds. Terminal finish is matte tin annealed over copper leadframe.
Does DMN10H170SFG-7 require gate resistors for EMI suppression?
A series gate resistor (typically 5–22Ω) is recommended to dampen gate oscillation caused by parasitic inductance and Crss feedback, especially in high-frequency (>300kHz) or high-dV/dt applications. The device's 1.1Ω intrinsic gate resistance alone is insufficient to suppress ringing in most practical layouts.
