Product details
Overview
DMTH4M70SPGWQ-13 from Diodes Incorporated is an AEC-Q101 qualified 40V N-channel enhancement-mode MOSFET in PowerDI8080-5 package, delivering 0.54 mΩ RDS(ON) @ 10V VGS, 460A continuous drain current at TC = +25°C, and rated for operation up to +175°C junction temperature - deployed in automotive engine management and high-current DC-DC converters.
For engineers reviewing the DMTH4M70SPGWQ-13 datasheet, DMTH4M70SPGWQ-13 pinout, DMTH4M70SPGWQ-13 application, or DMTH4M70SPGWQ-13 equivalent, key selection criteria include RDS(ON) stability over temperature, UIS ruggedness, wettable flank inspection capability, and AEC-Q101 qualification with PPAP support.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in high-temperature automotive power stages. Its 0.35°C/W RθJC enables efficient heat transfer to the PCB copper pad, while 117.1 nC total gate charge supports robust gate drive design at high-frequency operation.
The device integrates a body diode with 117.5 ns reverse-recovery time and 340.8 nC QRR, enabling synchronous rectification in buck converters. Its 100% production-tested UIS (924.5 mJ EAS) ensures survivability under inductive load transients common in solenoid and motor control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage for 12V/24V automotive bus applications with margin against load dump spikes. |
| RDS(ON) Max | 0.7 mΩ @ VGS = 10V - Enables <1W conduction loss at 400A, critical for high-efficiency power conversion. |
| ID Continuous | 460 A @ TC = +25°C - Supports high-current battery disconnect, starter relay, and DC-DC primary-side switching. |
| TJ Range | –55°C to +175°C - Validated for under-hood environments including turbocharger zones and transmission control units. |
| Qg | 117.1 nC - Determines gate driver power requirement and switching transition time in hard-switched topologies. |
| EAS | 924.5 mJ - Confirmed avalanche energy rating ensures reliability during unclamped inductive turn-off events. |
| Ciss | 10053 pF - Impacts gate drive loop stability and Miller effect in high-side configurations. |
Pinout & Package
Package: PowerDI®8080-5 - thermally enhanced surface-mount package with exposed drain pad and wettable flank terminals for automated optical inspection (AOI) and solder joint quality verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (G) | Gate | Control terminal requiring ≤±20V bias; 2.0 Ω gate resistance minimizes ringing in high-dV/dt environments. |
| Pins 2–5 (S) | Source | Four parallel source terminals reduce parasitic inductance and improve current sharing in high-frequency switching. |
| Drain Pad (Bottom) | Drain | Exposed copper thermal pad serves as primary current path and heatsink interface; requires full-solder coverage per JEDEC J-STD-020. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified & PPAP capable | Validated for automotive production use with documented change control and IATF 16949 manufacturing. |
| Wettable flank terminals | Enables 100% AOI detection of solder fillet height and voiding on side-view camera systems. |
| 100% UIS tested in production | Each unit passes unclamped inductive switching stress test, eliminating field failures from transient overvoltage. |
| +175°C maximum junction temperature | Supports placement in high-ambient zones (e.g., near exhaust manifolds) without derating or forced cooling. |
| Low Coss / Crss ratio | 5786 pF Coss and 116 pF Crss enable stable hard-switching with reduced Miller-induced shoot-through risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4M72SPGWQ-13 | Improved RDS(ON) (0.52 mΩ typ), same package and AEC-Q101 qualification. | Direct drop-in replacement with higher efficiency; recommended for new designs per Diodes' notice. | Select for new designs requiring lowest possible conduction loss and latest process revision. |
| IPB036N04LGATMA1 (Infineon) | 40V, 0.36 mΩ RDS(ON), TO-leadless package, different pinout and thermal footprint. | Higher current density but requires PCB redesign; lacks wettable flank for AOI compatibility. | Consider only when upgrading thermal performance justifies layout rework and AOI process adjustment. |
Compared with DMTH4M70SPGWQ-13, the DMTH4M72SPGWQ-13 offers lower RDS(ON) without changing footprint or qualification status, while the Infineon IPB036N04LGATMA1 delivers superior conduction loss at the cost of mechanical and inspection incompatibility.

FAQ
Is DMTH4M70SPGWQ-13 recommended for new designs?
No - Diodes Incorporated explicitly states "NOT RECOMMENDED FOR NEW DESIGNS" in the datasheet and recommends DMTH4M72SPGWQ-13 as the updated replacement. The DMTH4M70SPGWQ-13 remains available for legacy production continuity but lacks the improved RDS(ON) and process enhancements of the newer variant.
What does "wettable flank" mean for this MOSFET?
Wettable flank refers to vertically plated sidewalls on the source and gate terminals of the PowerDI8080-5 package, enabling automated optical inspection (AOI) systems to verify solder fillet formation and detect voids or insufficient wetting - a critical requirement for automotive safety-critical assemblies.
How is the 460A current rating validated?
The 460A continuous drain current is measured at case temperature TC = +25°C with the device mounted on a 1-inch square 2oz copper thermal pad, per Note 6 in the datasheet. Derating applies above +25°C case temperature, reaching 325A at TC = +100°C.
Does DMTH4M70SPGWQ-13 support synchronous rectification?
Yes - its body diode exhibits 117.5 ns reverse-recovery time and 340.8 nC QRR, verified under IF = 25A and di/dt = 100A/μs conditions. These parameters support reliable synchronous rectification in high-frequency DC-DC converters without excessive switching loss or voltage overshoot.
