Product details
Overview
DMTH8008LFG-13 from Diodes Incorporated is an 80V, 70A N-channel enhancement-mode MOSFET in PowerDI®3333-8 package, rated for +175°C operation, with RDS(ON) = 6.9 mΩ @ VGS = 10V and 10.4 mΩ @ VGS = 4.5V, optimized for high-efficiency DC-DC converters and automotive-grade power management.
For engineers reviewing the DMTH8008LFG-13 datasheet, DMTH8008LFG-13 pinout, DMTH8008LFG-13 application, or DMTH8008LFG-13 equivalent, key selection criteria include its low Qgd × RDS(ON) figure-of-merit, 100% production-tested UIS robustness, thermally efficient exposed-drain package, and AEC-Q-compliant qualification path (via DMTH8008LFGQ).
Technical Context
This MOSFET employs trench-gate silicon technology to achieve ultra-low on-resistance while maintaining fast switching performance. Its gate threshold voltage (1.2–2.5 V) enables compatibility with 3.3 V and 5 V logic drivers, and its body diode exhibits tRR = 42 ns and QRR = 53 nC under 100 A/μs di/dt conditions.
The device's thermal design centers on a low RθJC of 3 °C/W (junction-to-case), enabled by the exposed drain pad in the PowerDI3333-8 package. It supports continuous operation up to TJ = +175°C, with RDS(ON) normalized to ≤2.4× at 175°C - critical for under-hood automotive and industrial power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 80 V - Supports 48 V nominal bus systems with 20 % margin for transients. |
| RDS(ON) @ 10 V | 6.9 mΩ max - Enables <1.4 W conduction loss at 70 A, reducing heatsink requirements. |
| RDS(ON) @ 4.5 V | 10.4 mΩ max - Ensures usable channel enhancement with standard 5 V gate drivers. |
| Qg @ 10 V | 37.7 nC - Low total gate charge minimizes driver power and switching energy loss. |
| EAS | 162 mJ - Robust unclamped inductive switching capability improves system fault tolerance. |
| TJ max | +175°C - Qualified for extended-life operation in high-ambient environments (e.g., engine compartments). |
| Ciss | 2254 pF - Predictable input capacitance simplifies gate drive loop stability analysis. |
Pinout & Package
Package: PowerDI®3333-8 - thermally enhanced surface-mount package with exposed drain pad (pins 5–8), 3.3 mm × 3.3 mm footprint, 0.8 mm height, and UL 94V-0 molded compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Gate | Control terminal; requires ≤±20 V gate-source voltage; low Rg = 1.98 Ω aids fast turn-on/turn-off. |
| 2, 3, 4 | Source | Return path for load current; tied to PCB ground plane; low-inductance layout critical for EMI control. |
| 5–8 | Drain (exposed pad) | Main power output node; soldered directly to large copper area for thermal dissipation (RθJC = 3 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested in production | Guarantees avalanche ruggedness without derating - eliminates need for external snubbers in flyback or buck-boost topologies. |
| PowerDI3333-8 package | Reduces board area by 67 % vs SO-8; exposes drain on bottom for direct thermal coupling to heatsink or inner-layer copper. |
| Low Qgd × RDS(ON) FOM | Qgd = 7.8 nC × RDS(ON) = 6.9 mΩ → 53.8 mΩ·nC - minimizes Miller-induced switching delay and shoot-through risk. |
| +175°C operation | Rated junction temperature enables use in sealed enclosures or near heat sources without forced air cooling. |
| Halogen- and antimony-free "Green" construction | Meets JEDEC J-STD-020 Level 1 moisture sensitivity and RoHS 3 (2015/863/EU) compliance without performance trade-offs. |
Applications
| Automotive Body Control Module (BCM) | Industrial 48 V DC-DC Converter |

IC Role / Device Role / Timing Role: Low-profile, high-current power switch operating at 500 kHz switching frequency with minimal thermal rise. Use Value: PowerDI3333-8 footprint saves >60 % PCB area vs SO-8; 10.4 mΩ RDS(ON) @ 4.5 V allows direct PWM control from MCU GPIO. |
Use Scenario: H-bridge half-bridge driver for precision stepper motor in battery-powered infusion pump. IC Role / Device Role / Timing Role: Low-conduction-loss switch enabling microstepping with <100 mV dropout at 2 A continuous.

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 |
|---|---|---|---|
| Vishay SiR626DP | RDS(ON) = 5.2 mΩ @ 10 V, but only rated to +150°C; larger PowerPAK® 5x6 package (30 mm² vs 10.9 mm²). | Lacks AEC-Q qualification path; unsuitable for under-hood automotive use above 150°C ambient. | Select when lower RDS(ON) outweighs thermal rating and board space constraints. |
| Infineon BSC014N06LS6 | RDS(ON) = 1.4 mΩ @ 10 V, but VDSS = 60 V; PG-TSDSON-8 package with higher RθJA (62 °C/W). | Not suitable for 48 V bus systems requiring 20 % transient margin; limited to ≤60 V designs. | Prefer for 24 V or lower-input industrial SMPS where ultra-low conduction loss is primary. |
Compared with SiR626DP and BSC014N06LS6, DMTH8008LFG-13 uniquely balances 80 V rating, +175°C capability, compact footprint, and production-tested avalanche robustness - making it optimal for space-constrained, high-reliability 48 V power stages where thermal margin and long-term stability are non-negotiable.

FAQ
What is the maximum continuous drain current at TC = +100°C?
The DMTH8008LFG-13 supports 49 A continuous drain current at case temperature +100°C, per the Absolute Maximum Ratings table (Note 7). This reflects derating from the 70 A rating at +25°C due to thermal resistance limitations and safe operating area constraints.
Is the PowerDI3333-8 package lead-free and RoHS compliant?
Yes - the DMTH8008LFG-13 uses matte tin annealed over copper leadframe and complies with EU RoHS 2015/863/EU (RoHS 3), including exemption clauses. It is also halogen- and antimony-free ("Green") per Diodes' specification (<900 ppm Br/Cl, <1000 ppm Sb).
Does this MOSFET require a gate resistor for reliable switching?
A gate resistor is recommended: typical value is 6 Ω (per datasheet switching time test condition). It controls dV/dt, suppresses ringing, and prevents shoot-through in half-bridge configurations; omission risks oscillation and gate driver overstress due to low Rg = 1.98 Ω.
How does the body diode performance compare to discrete Schottky alternatives?
The integrated body diode has VSD = 0.8–1.2 V at 20 A and tRR = 42 ns, offering lower forward drop than standard PN diodes but higher than Schottky. It eliminates external diode count in synchronous rectifiers, though Schottky co-packaging may be preferred for ultra-low VF in high-frequency designs.
