Product details
Overview
DMTH45M5SPDW from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for 40V VDSS, 5.5mΩ RDS(ON) @ 10V, and 79A continuous drain current at TC = +25°C. It delivers high-efficiency power switching in compact DC-DC converters and wireless charging systems operating up to +175°C junction temperature.
For engineers reviewing the DMTH45M5SPDW datasheet, DMTH45M5SPDW pinout, DMTH45M5SPDW application, or DMTH45M5SPDW equivalent, key selection criteria include its dual-channel layout, wettable flank terminals for automated optical inspection, 100% production-tested UIS robustness, and low gate charge (13.2nC) enabling fast switching with reduced drive loss.
Technical Context
This dual MOSFET integrates two independent N-channel silicon devices sharing a common thermal pad, optimized for synchronous buck topologies and half-bridge configurations. Its 2.5°C/W RθJC and exposed drain pad support high-power density designs where thermal management is critical.
The device features tightly controlled VGS(TH) (2.0–3.5V), low Ciss (1083pF), and minimal Qgd/Qg ratio (0.9/13.2nC), enabling clean turn-off with reduced Miller-induced shoot-through risk in high-frequency (>1MHz) switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Supports 12V/24V input rails with 2× safety margin against transients |
| RDS(ON) max | 5.5mΩ @ VGS = 10V - Enables <1.4W conduction loss at 79A, critical for thermally constrained PCBs |
| ID continuous | 79A @ TC = +25°C - Delivers high current per channel without external heatsink in optimized layouts |
| Qg | 13.2nC - Reduces gate driver power demand and enables efficient 500kHz–1MHz operation |
| TJ max | +175°C - Allows operation in under-hood automotive modules or sealed industrial enclosures |
| Ciss | 1083pF - Limits capacitive loading on gate drivers while maintaining fast dV/dt immunity |
| EAS | 20.6mJ - Withstands repetitive inductive energy spikes in motor drive or converter freewheeling |
Pinout & Package
Package: PowerDI5060-8/SWP (Type UXD), surface-mount, thermally enhanced with exposed drain pad and wettable flank leads for solder joint inspection.

| D1 | Drain of Channel 1 | High-side switching node; electrically and thermally connected to exposed copper pad |
| S2 | Source of Channel 2 | Independent source terminal for second channel; supports asymmetrical load balancing |
| G2 | Gate of Channel 2 | Isolated control input enabling independent timing or dead-time control per channel |
| D2 | Drain of Channel 2 | Second high-side node; shares thermal pad but maintains electrical isolation from D1 |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH45M5SPDWQ | Automotive-grade variant (AEC-Q101 qualified); identical RDS(ON), VDSS, and package | Required for under-hood automotive modules; includes extended temperature screening and traceability | Select when ISO/TS 16949 compliance or PPAP documentation is mandatory |
| IPB80N04S4-02 | Single-channel TO-263 package; 2.0mΩ RDS(ON) but no dual configuration or wettable flanks | Requires two devices and additional PCB area; lacks integrated thermal symmetry of dual die | Choose only if higher current per channel (>80A) outweighs board space and assembly cost penalties |
Compared with DMTH45M5SPDWQ, the base part offers identical electrical performance at lower cost and lead time but lacks AEC-Q101 validation; versus IPB80N04S4-02, it saves 35% board area and eliminates inter-device timing skew, though with 1.75× higher RDS(ON).

FAQ
What is the maximum safe operating frequency for DMTH45M5SPDW in a synchronous buck converter?
The device supports stable operation up to 1MHz due to its 5.4ns turn-on delay and 4.5ns fall time, provided gate drive strength exceeds 2A peak and PCB layout minimizes loop inductance. Thermal limits-rather than switching speed-typically constrain frequency in practice, especially above 500kHz with >40A load current.
Can DMTH45M5SPDW be used in parallel configurations for higher current handling?
Yes-its matched RDS(ON) tracking (±15% typical between channels) and low thermal resistance enable direct paralleling without current-sharing resistors. However, symmetrical gate routing and identical trace lengths are mandatory to prevent dynamic imbalance during 16.1ns turn-off delay transitions.
Does the PowerDI5060-8 package require special stencil design for reflow soldering?
Yes-the exposed drain pad demands a 70–80% copper-filled thermal pad with 0.15mm thick stencil and 5×5 array of 0.3mm diameter solder paste apertures. Insufficient paste volume causes voiding that degrades RθJC beyond the rated 2.5°C/W, risking thermal runaway at full load.
How does the 100% UIS testing impact reliability in real-world DC-DC converter applications?
Every unit undergoes single-pulse avalanche stress at 20.3A/20.6mJ, verifying robustness against worst-case inductive kickback during MOSFET short-circuit events. This eliminates infant mortality in flyback snubbers and synchronous rectifier freewheeling paths where voltage overshoot exceeds VDSS by >15%.
