Product details
Overview
DMTH10H010SCT from Diodes Incorporated is a 100V, 100A N-channel enhancement-mode power MOSFET in TO220AB package, featuring 7.4 mΩ typical RDS(ON) at VGS = 10V, 175°C maximum junction temperature, and 4468 pF input capacitance. It serves as a high-current switching element in primary-side power conversion stages of industrial DC-DC converters and motor drive half-bridges.
For engineers reviewing the DMTH10H010SCT datasheet, DMTH10H010SCT pinout, DMTH10H010SCT application, or DMTH10H010SCT equivalent, key selection criteria include its 90A continuous body diode rating, 0.8°C/W thermal resistance (junction-to-case), fast 18.6 ns turn-on delay, low 31.6 pF reverse transfer capacitance, and RoHS-compliant green packaging for thermally demanding power management designs.
Technical Context
This MOSFET employs planar silicon process technology optimized for high-voltage ruggedness and low conduction loss. Its 100V BVDSS rating supports 48V bus systems with margin, while the 175°C TJ max enables operation in sealed enclosures without derating below 100°C ambient.
The device integrates an intrinsic body diode with 54.5 ns reverse recovery time and 106.4 nC QRR, enabling synchronous rectification in non-isolated buck topologies. Gate charge parameters (Qg = 56.4 nC, Qgd = 14.0 nC) support efficient 100–500 kHz switching with standard gate drivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP100N10F7 | 100V, 100A, RDS(ON) = 8.5 mΩ @ 10V; higher Ciss (5200 pF); TO220FP package (isolated tab) | Higher gate drive loss due to +16% Ciss; requires larger gate resistor to damp ringing | Prefer when electrical isolation between tab and PCB ground is mandatory |
| IXFH100N10L2 | 100V, 100A, RDS(ON) = 7.0 mΩ @ 10V; lower Qg (48 nC); TO247AC package | Superior switching speed but larger footprint and higher cost; no RoHS-3 compliance | Choose for ultra-high-frequency (>1 MHz) SMPS where 12% lower Qg justifies 3.5× package cost increase |
Compared with STP100N10F7 and IXFH100N10L2, DMTH10H010SCT delivers optimal balance of low conduction loss, industry-standard TO220AB mechanical compatibility, and full RoHS-3/halogen-free compliance-making it preferred for cost-sensitive, thermally constrained industrial power modules requiring long-term supply stability.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMTH10H010SCT supports 80A continuous drain current at TC = +100°C, as specified in its Absolute Maximum Ratings table. This derating from 100A at 25°C reflects thermal limitations of the TO220AB package under real-world heatsink conditions, and must be verified using the transient thermal impedance curve (Figure: Transient Thermal Resistance) for pulsed loads.
Does this MOSFET require a gate resistor for safe operation in hard-switching applications?
Yes-a minimum 6Ω gate resistor is recommended, based on the datasheet's switching time test condition (Rg = 6Ω). This value damps gate oscillation, limits peak gate current to <2A during 10V transitions, and prevents unintended turn-on from dv/dt coupling, especially critical given its 31.6 pF Crss and 100V operation.
Can the body diode be used for synchronous rectification in a buck converter?
Yes-the body diode has characterized reverse recovery parameters: tRR = 54.5 ns and QRR = 106.4 nC at IF = 13A. These values enable use in medium-frequency (≤500 kHz) non-isolated buck converters, though external Schottky diodes remain preferable above 300 kHz due to lower QRR-induced losses.
Is the TO220AB package electrically isolated between drain and mounting tab?
No-the drain terminal is directly connected to the metal tab in the TO220AB package. Electrical isolation requires either a mica or ceramic insulator washer plus shoulder washers, or use of the TO220FP variant (which features a fully isolated tab), as confirmed in the Mechanical Data section and Package Outline Dimensions diagram.
