Product details
Overview
DMT10H9M9SH3 from Diodes Incorporated is a 100V N-channel enhancement-mode MOSFET in TO251 (TH3) package, delivering 9 mΩ RDS(ON) at VGS = 10 V and 84 A continuous drain current at TC = +25°C. It features low input capacitance (Ciss = 2085 pF), fast switching (tF = 17.3 ns), and integrated body diode with VSD = 0.8–1.2 V at 13 A - optimized for motor control and LED backlighting power stages.
For engineers reviewing the DMT10H9M9SH3 datasheet, DMT10H9M9SH3 pinout, DMT10H9M9SH3 application, or DMT10H9M9SH3 equivalent, key selection criteria include verified RDS(ON) @ 6 V/10 V, thermal resistance RθJC = 1.1 °C/W, avalanche energy EAS = 181.5 mJ, gate charge Qg = 30 nC, and TO251 mechanical compatibility with PCB layout constraints.
Technical Context
This MOSFET employs planar trench-gate technology to achieve low on-resistance while maintaining robust switching performance and avalanche ruggedness. Its gate threshold voltage (VGS(TH) = 2–4 V) enables reliable turn-on with standard 5 V or 3.3 V logic-level drivers, and its low Coss (609 pF) minimizes switching losses during hard-switched operation.
The device integrates a fast-recovery body diode (tRR = 45 ns, QRR = 68 nC) suitable for synchronous rectification and freewheeling in DC-DC converters and motor H-bridges. Thermal design is supported by a low junction-to-case resistance (1.1 °C/W) and operation up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - Maximum blocking voltage for high-side switch applications in 48 V industrial systems or automotive subsystems. |
| RDS(ON) | 9 mΩ @ VGS = 10 V, ID = 20 A - Enables <1.8 W conduction loss at 45 A, critical for thermally constrained motor drives. |
| ID (continuous) | 84 A @ TC = +25°C - Supports high-current load switching without external heatsink when mounted on infinite heatsink. |
| Qg | 30 nC - Determines gate drive power requirement; compatible with standard 1 A peak gate drivers for ≤500 kHz operation. |
| EAS | 181.5 mJ - Confirmed single-pulse avalanche capability ensures reliability under inductive load turn-off stress. |
| RθJC | 1.1 °C/W - Enables precise junction temperature estimation using case temperature measurement in thermal management. |
| tF | 17.3 ns - Fast fall time reduces switching transition losses in high-frequency PWM applications like backlight inverters. |
Pinout & Package
Package: TO251 (Type TH3), surface-mount, 3-terminal molded plastic case with matte tin–annealed copper leadframe; UL 94V-0 rated; weight ≈ 0.33 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path collector | Exposed metal tab is electrically connected to Drain - must be isolated from heatsink unless referenced to same potential. |
| Source | Current return path / reference node | Common connection point for gate driver return and load ground; defines VGS reference. |
| Gate | Control terminal | High-impedance input requiring low-inductance routing; sensitive to ESD and ringing due to RG = 1.7 Ω intrinsic resistance. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) @ 6 V | 14 mΩ - Ensures usable conduction performance with 5 V microcontroller GPIO or level-shifted gate drive. |
| Low Ciss | 2085 pF - Reduces Miller effect and gate drive power, enabling efficient operation above 200 kHz. |
| Avalanche-rated | EAS = 181.5 mJ - Eliminates need for external snubbers in inductive load switching circuits. |
| Green compound | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - Meets IPC-1752A material declaration requirements. |
| RoHS 3 compliant | EU Directive 2015/863/EU - Qualified for consumer, industrial, and automotive supply chains requiring full substance compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXTP110N10T | RDS(ON) = 10.5 mΩ @ 10 V; higher Qg = 42 nC; TO220 package | Requires through-hole mounting and larger heatsink footprint; slower switching | Preferred where board space allows through-hole assembly and lower cost outweighs efficiency gain |
| STP100N10F7 | RDS(ON) = 8.5 mΩ @ 10 V; lower RθJC = 0.9 °C/W; TO220FP package | Higher thermal performance but non-isolated tab; not RoHS 3 compliant | Selected when maximum thermal headroom is required and halogen-free compliance is not mandated |
Compared with IXTP110N10T and STP100N10F7, DMT10H9M9SH3 offers superior surface-mount integration, full RoHS 3 compliance, and balanced trade-offs between conduction loss, switching speed, and thermal resistance - making it optimal for space-constrained, high-efficiency industrial and automotive modules.

FAQ
Is DMT10H9M9SH3 qualified for automotive applications?
No - DMT10H9M9SH3 is not AEC-Q101 qualified. While it meets RoHS 3 and green compound requirements, Diodes states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing - which this part does not carry. For automotive use, contact Diodes directly for qualified alternatives such as the DMT10H9M9SH3-A.
What is the maximum safe operating temperature for DMT10H9M9SH3?
The absolute maximum junction temperature is +150°C, and the storage temperature range is –55°C to +150°C. Operation above +150°C risks permanent degradation. Derating curves in Figure 5 and Figure 6 confirm RDS(ON) increases by ~2× from –55°C to +150°C at fixed VGS, requiring thermal design to maintain TJ ≤ 125°C for long-term reliability.
Can DMT10H9M9SH3 be used with 5 V gate drive?
Yes - VGS(TH) is 2–4 V, and RDS(ON) is specified at 14 mΩ @ VGS = 6 V and ID = 5 A. At 5 V, typical RDS(ON) is ~16–18 mΩ (per Figure 3), supporting moderate-current switching (≤40 A) with acceptable conduction loss in non-critical thermal environments.
Does DMT10H9M9SH3 have an integrated ESD protection diode on the gate?
No - the datasheet does not specify gate ESD protection. The gate-source leakage IGSS is rated at ±100 nA at ±20 V, and no human-body-model (HBM) or charged-device-model (CDM) ESD rating is provided. External gate protection (e.g., 12 V Zener clamp) is recommended for handling and PCB assembly in uncontrolled ESD environments.
