Product details
Overview
DMTH8008LPSQ-13 from Diodes Incorporated is an AEC-Q101-qualified 80V N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for continuous drain current of 91A at TC = +25°C, RDS(ON) = 7.8 mΩ @ VGS = 10V, and operation up to +175°C junction temperature. It is engineered for high-reliability automotive DC-DC converters and load switches requiring robust UIS performance and low conduction loss.
For engineers reviewing the DMTH8008LPSQ-13 datasheet, DMTH8008LPSQ-13 pinout, DMTH8008LPSQ-13 application, or DMTH8008LPSQ-13 equivalent, key selection criteria include its 80V VDSS, 100% production-tested UIS capability, thermal resistance RθJC = 1.5°C/W, AEC-Q101 qualification status, and PowerDI5060-8 thermal pad layout compatibility.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-temperature automotive environments. Its gate threshold voltage (1.3–2.8V) enables reliable turn-on with standard 4.5V logic-level drivers, while the 41.2 nC total gate charge at VGS = 10V supports efficient PWM control in DC-DC topologies.
The device integrates an intrinsic body diode with tRR = 61 ns and QRR = 181 nC, enabling synchronous rectification in buck converters. Its 1.5°C/W junction-to-case thermal resistance and exposed drain pad design allow direct mounting to PCB copper planes for effective heat extraction in space-constrained modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 80 V - Withstands transient overvoltage spikes up to 80V in 12V/24V automotive systems without breakdown. |
| RDS(ON) | 7.8 mΩ @ VGS = 10V - Delivers <0.5W conduction loss at 91A, critical for high-efficiency power stages. |
| ID (TC = +25°C) | 91 A - Supports high-current load switching in engine control units and battery management subsystems. |
| TJ Range | −55°C to +175°C - Certified for under-hood applications where ambient exceeds 125°C. |
| UIS Rating | 23 A / 26.5 mJ - 100% production-tested unclamped inductive switching ensures field reliability in relay replacement circuits. |
| QG (VGS = 10V) | 41.2 nC - Enables precise gate drive timing in 200–500 kHz DC-DC controllers with minimal driver power demand. |
| Ciss | 2345 pF - Low input capacitance reduces Miller effect and improves noise immunity in high-dV/dt environments. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7 | Drain (D) | Seven parallel drain connections tied to internal die source metallization and exposed thermal pad - primary current path and thermal conduction path to PCB. |
| 8 | Gate (G) | Single gate terminal with 1.7 Ω gate resistance - interfaces directly with standard gate drivers without external series resistor in most 400 kHz designs. |
| - (Exposed Pad) | Drain (D) | Integral part of drain terminal; must be soldered to ≥1 in² 2oz copper pour for RθJC = 1.5°C/W performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7AG | 60V VDSS, 2.2 mΩ @ 10V, PowerFLAT 5x6 | Limited to 60V systems; lower RDS(ON) but insufficient for 48V+ transients in 80V-rated architectures. | Select only if system max VDS ≤ 60V and thermal budget permits smaller package. |
| IXTQ80N10P | 100V VDSS, 10.5 mΩ @ 10V, TO-220AB | Higher RDS(ON) and through-hole packaging increases board area and thermal resistance vs. PowerDI5060-8. | Choose when legacy through-hole assembly is required and 100V margin justifies 35% higher conduction loss. |
Compared with STL220N6F7AG and IXTQ80N10P, DMTH8008LPSQ-13 uniquely balances 80V rating, ultra-low 7.8 mΩ on-resistance, thermally optimized surface-mount packaging, and full AEC-Q101 validation - making it optimal for next-generation compact, high-efficiency automotive power stages.

FAQ
What is the maximum allowable gate-source voltage for DMTH8008LPSQ-13?
The absolute maximum VGS rating is ±20V per the datasheet's Maximum Ratings table. Operation beyond ±15V risks permanent gate oxide damage, especially at elevated temperatures. For robust design, limit gate drive to +12V/−5V with active clamping or Zener protection.
Does DMTH8008LPSQ-13 require a gate resistor in typical automotive applications?
A gate resistor is recommended to dampen ringing and control dV/dt, particularly in high-frequency DC-DC converters. With 1.7 Ω intrinsic gate resistance and 41.2 nC QG, a 5–10 Ω external resistor provides optimal trade-off between switching speed and EMI suppression for 200–500 kHz operation.
How is thermal performance affected if the exposed drain pad is not soldered to PCB copper?
Without soldering the exposed drain pad to ≥1 in² 2oz copper, RθJC degrades from 1.5°C/W to >10°C/W, causing junction temperature to exceed 175°C at <30A. Thermal vias under the pad and connection to inner-layer ground planes are mandatory for rated current operation.
Is DMTH8008LPSQ-13 suitable for synchronous rectification in isolated flyback converters?
Yes - its 61 ns body diode reverse recovery time and low QRR (181 nC) enable efficient synchronous rectification at up to 300 kHz. However, ensure gate drive maintains VGS > 4.5V during conduction to avoid body diode conduction and associated losses.
