Product details
Overview
DMTH10H010LCT from Diodes Incorporated is a 100V, 108A N-channel enhancement-mode MOSFET in TO220AB package, featuring 9.5mΩ RDS(ON) at VGS = 10V, rated for continuous operation up to +175°C, and qualified to AEC-Q101 - designed for high-current DC-DC converters and motor control stages where thermal robustness and low conduction loss are critical.
For engineers reviewing the DMTH10H010LCT datasheet, DMTH10H010LCT pinout, DMTH10H010LCT application, or DMTH10H010LCT equivalent, this page delivers verified electrical parameters, thermal performance data, TO220AB terminal mapping, and AEC-Q101-compliant use context for automotive-grade power switching design.
Technical Context
This MOSFET employs planar silicon technology optimized for low RDS(ON) and fast switching with 58.4nC total gate charge and 44pF reverse transfer capacitance (Crss) at VDS = 50V. Its 0.9°C/W junction-to-case thermal resistance enables high-power dissipation when mounted on heatsinks.
The device integrates a robust body diode with 49.8ns reverse recovery time and 85.1nC QRR, supporting synchronous rectification and freewheeling in hard-switched topologies. Gate threshold voltage (1.4–3.5V) ensures stable turn-on under wide temperature range (−55°C to +175°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100V - Withstands 80V DC bus transients in 48V industrial systems without avalanche stress. |
| RDS(ON) | 9.5mΩ @ VGS = 10V - Delivers ≤1.3W conduction loss at 13A, enabling compact thermal design. |
| ID (TC = 25°C) | 108A - Supports high-current half-bridge legs in motor inverters and server VRMs. |
| Qg | 58.4nC - Matches standard gate drivers (e.g., UCC27531) without requiring external boost circuitry. |
| RθJC | 0.9°C/W - Enables >150W steady-state power dissipation with 100°C case temperature rise above ambient. |
| TJ Range | −55°C to +175°C - Certified for under-hood automotive environments and industrial furnace controls. |
| Ciss | 4166pF - Low input capacitance reduces driver power demand and improves EMI margin in 100kHz–500kHz SMPS. |
Pinout & Package

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 |
|---|---|---|---|
| STP110N10F7 | 100V, 110A, 7.5mΩ @ 10V; DPAK package; lower RDS(ON) but no AEC-Q101 certification. | Not qualified for automotive; limited to industrial/commercial DC-DC where qualification is not mandated. | Select when higher current density is needed and qualification is not required; verify PCB thermal relief for DPAK. |
| IXTP110N10L2 | 100V, 110A, 9.0mΩ @ 10V; TO220FP (full-pack) package; 1.5W PD (ambient); no AEC-Q101. | Lower thermal capability in open-frame layout; unsuitable for high-ambient automotive use. | Prefer for cost-sensitive commercial power supplies where case temperature stays below 85°C. |
Compared with STP110N10F7 and IXTP110N10L2, DMTH10H010LCT trades marginal RDS(ON) increase for guaranteed AEC-Q101 reliability, TO220AB mechanical robustness, and validated +175°C operation - making it the only choice for thermally demanding automotive power modules.

FAQ
Is DMTH10H010LCT pin-compatible with standard TO220AB MOSFETs?
Yes - it uses the industry-standard TO220AB pinout: Drain (tab), Source (center lead), Gate (left lead when tab faces outward). Mechanical dimensions match JEDEC TO220AB spec, including 2.54mm lead pitch and 5.08mm lead spacing, ensuring drop-in replacement in existing layouts.
What is the maximum recommended gate drive voltage?
The absolute maximum gate-source voltage is ±20V, but the device is characterized and optimized for 10V drive. Driving above 12V yields diminishing RDS(ON) improvement while increasing gate oxide stress risk; 10V is the design target for AEC-Q101 reliability compliance.
Does the body diode support continuous conduction mode (CCM) in synchronous rectifiers?
Yes - the body diode has 90A maximum continuous forward current rating at TC = 25°C and 49.8ns reverse recovery time, enabling reliable CCM operation in 100–300kHz synchronous buck converters when paired with appropriate gate timing control.
How does thermal performance change at elevated ambient temperatures?
At TA = 85°C with standard FR-4 board mount, continuous drain current derates to 76A (per datasheet). Junction-to-ambient thermal resistance remains 61°C/W, but effective power dissipation drops to ~95W due to reduced ΔT margin - heatsink mounting restores full 108A rating.
