Product details
Overview
DMTH8008SFG-13 from Diodes Incorporated is an 80V, 68A N-channel enhancement-mode MOSFET in PowerDI®3333-8 package, rated for +175°C operation, with RDS(ON) = 7 mΩ @ VGS = 10V and Qgd × RDS(ON) figure-of-merit optimized for high-efficiency DC-DC converters in automotive and industrial power management.
For engineers reviewing the DMTH8008SFG-13 datasheet, DMTH8008SFG-13 pinout, DMTH8008SFG-13 application, or DMTH8008SFG-13 equivalent, key selection criteria include thermal robustness at 175°C, low conduction loss under 10V gate drive, UIS-rated ruggedness, and board-area savings versus SO-8 in space-constrained power stages.
Technical Context
This MOSFET employs trench-gate silicon technology to achieve simultaneous low RDS(ON) (5.0 mΩ typ @ 10V) and fast switching (tD(OFF) = 27 ns, Qgd = 8.6 nC), enabling high-frequency synchronous buck topologies. Its 3.0°C/W RθJC and exposed drain pad support direct thermal coupling to PCB copper planes.
The device integrates a robust body diode with tRR = 40.6 ns and QRR = 50.9 nC, validated for continuous 100 A/μs reverse recovery stress. It is fully characterized for operation across –55°C to +175°C junction temperature range, with VGS(TH) stable from 2–4 V over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 80 V - supports 48V input rails with 20% margin for transients |
| RDS(ON) | 7 mΩ max @ VGS = 10V - limits conduction loss to ≤1.0 W at 14A DC |
| ID (TC = 25°C) | 68 A - enables high-current single-phase power stages without paralleling |
| Qgd | 8.6 nC - reduces Miller-induced switching delay and improves dV/dt immunity |
| EAS | 174.85 mJ - withstands unclamped inductive energy in motor drive or converter fault conditions |
| TJ Max | +175°C - allows operation in engine bay or sealed industrial enclosures without derating |
| RθJC | 3.0°C/W - enables >40W power dissipation with minimal case-to-heatsink ΔT |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-temperature MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH8008LSDQ-13 | Same die, AEC-Q101 qualified; identical RDS(ON), Qgd, and thermal specs | Required for automotive production; includes extended qualification testing and PPAP documentation | Select when automotive qualification and traceability are mandatory |
| IPB070N10N5ATMA1 | 100V rating, 7.0 mΩ @ 10V, but larger TO-263-7 package and higher RθJA (50°C/W) | Suitable for lower-frequency (<300 kHz), less space-constrained designs where thermal mass compensates for lower density | Select only if 100V margin is required and board area is not constrained |
Compared with DMTH8008SFG-13, the DMTH8008LSDQ-13 adds automotive qualification without sacrificing electrical or thermal performance, while the IPB070N10N5ATMA1 trades board-area efficiency and high-frequency suitability for higher voltage headroom and legacy package compatibility.

FAQ
What is the maximum continuous drain current at TC = +100°C?
The DMTH8008SFG-13 supports 48 A continuous drain current at case temperature +100°C, as specified in its Absolute Maximum Ratings table. This value is derived from thermal derating based on RθJC = 3.0°C/W and TJ(max) = +175°C, ensuring safe operation without exceeding junction temperature limits under sustained load.
Does this MOSFET require a gate resistor for stability in high-speed switching?
Yes - a gate resistor of 2–6 Ω is recommended to dampen ringing and control dI/dt during turn-on/turn-off. The device's 1.8 Ω typical gate resistance and 8.6 nC Qgd make it sensitive to PCB layout parasitics; proper gate drive impedance prevents oscillation and ensures consistent timing in 500 kHz+ applications.
Can DMTH8008SFG-13 be used in synchronous rectification configurations?
No - it is an N-channel enhancement-mode MOSFET intended for high-side or low-side switching, not synchronous rectification. Its body diode forward voltage (0.8–1.2 V) and reverse recovery characteristics are optimized for controlled switching, not freewheeling conduction; dedicated synchronous rectifier MOSFETs have lower VSD and faster tRR.
Is the PowerDI3333-8 package compatible with standard SO-8 reflow profiles?
Yes - the PowerDI3333-8 uses matte tin annealed terminations and complies with J-STD-020 moisture sensitivity level 1, supporting standard lead-free reflow profiles (peak 260°C). Its smaller footprint requires updated stencil aperture design and placement accuracy ±0.05 mm, but thermal mass is lower than SO-8, reducing soak time requirements.
