Product details
Overview
DMT8008LK3-13 from Diodes Incorporated is an 80V N-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for 95A continuous drain current at TC = +25°C, with RDS(on) of 7.0mΩ @ VGS = 10V and 11mΩ @ VGS = 4.5V, optimized for high-efficiency DC-DC converters and power management stages in industrial and lighting systems.
For engineers reviewing the DMT8008LK3-13 datasheet, DMT8008LK3-13 pinout, DMT8008LK3-13 application, or DMT8008LK3-13 equivalent, key selection criteria include its 1.1°C/W junction-to-case thermal resistance, 100% production-tested UIS robustness, low Qg (41.2nC @ 10V), and AEC-Q101-capable qualification path for automotive-grade deployment.
Technical Context
This MOSFET employs a trench-gate silicon process to achieve low RDS(on) and fast switching with controlled gate charge (Qgd = 10.6nC). Its body diode exhibits tRR = 61ns and QRR = 181nC under IF = 2A, di/dt = 100A/μs conditions, supporting synchronous rectification and hard-switched topologies.
The device operates across –55°C to +150°C junction temperature range, with thermal resistance RθJC = 1.1°C/W and RθJA = 45°C/W on 1-inch² copper pad - enabling high-power density designs without active cooling in space-constrained PCB layouts.

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 |
|---|---|---|---|
| STL110N8F7AG | 80V, 5.2mΩ @ 10V, TO252, but Qg = 52nC - 26% higher gate charge | Higher drive loss limits usable frequency to ≤350kHz in high-current VRMs | Prefer DMT8008LK3-13 where >500kHz operation or minimal gate drive power is required |
| ON-SEMI NTMFS5C673NL | 60V, 5.0mΩ @ 10V, same TO252 package, but lower VDSS and no UIS rating | Not suitable for 48V systems with >60V transients or inductive turn-off stress | Select DMT8008LK3-13 for 80V-rated, transient-robust designs requiring production-validated avalanche performance |
Compared with STL110N8F7AG and NTMFS5C673NL, DMT8008LK3-13 uniquely balances 80V rating, sub-7mΩ RDS(on), low Qg, and 100% UIS screening - making it optimal for high-reliability, high-frequency industrial and automotive power stages where both voltage headroom and switching efficiency are critical.

FAQ
What is the maximum safe operating junction temperature for DMT8008LK3-13?
The absolute maximum junction temperature is +150°C, validated across all electrical parameters in the datasheet. Derating begins at TJ > 125°C for continuous operation, and thermal design must ensure RθJA × PD + TA ≤ 150°C. The device's 1.1°C/W RθJC enables reliable operation at 76A with proper PCB copper area.
Does DMT8008LK3-13 support logic-level gate drive?
Yes - with VGS(th) ranging from 1.3V to 2.8V and RDS(on) = 11mΩ @ VGS = 4.5V, it is fully compatible with 3.3V and 5V logic outputs. Gate drive circuits must deliver ≥21.7nC (at 4.5V) to achieve specified switching times; a 1Ω series resistor is recommended for ringing suppression.
Is DMT8008LK3-13 qualified for automotive applications?
While not pre-qualified to AEC-Q101, Diodes states this part is manufactured in IATF 16949-certified facilities and supports PPAP documentation upon request. Its 100% UIS testing, halogen-free construction, and –55°C to +150°C rating align with automotive power system requirements, pending customer-specific qualification.
How does the body diode performance compare to Schottky alternatives?
The integrated body diode has VSD = 0.8–1.2V @ IS = 20A and tRR = 61ns, offering lower forward drop than standard silicon diodes but higher than Schottky. It eliminates external diode cost in synchronous rectifiers, though Schottky co-packaging may be preferred where <0.5V VF is mandatory at low currents.
