Product details
Overview
DMTH45M5SPDWQ-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for 40V VDSS, 5.5mΩ RDS(ON) @ 10VGS, and 79A continuous drain current at TC = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for high-reliability automotive power stages including wireless charging transmitters and synchronous rectification in DC-DC converters.
For engineers reviewing the DMTH45M5SPDWQ-13 datasheet, DMTH45M5SPDWQ-13 pinout, DMTH45M5SPDWQ-13 application, or DMTH45M5SPDWQ-13 equivalent, key selection criteria include its +175°C rated junction temperature, 100% production-tested UIS robustness, wettable flank terminals for automated optical inspection, and dual-channel layout enabling compact half-bridge or dual-phase configurations.
Technical Context
This dual MOSFET integrates two matched N-channel silicon die in a single PowerDI5060-8/SWP (Type UXD) package with exposed drain pads for thermal performance. Its gate threshold voltage (2.0–3.5V) enables direct drive from standard 3.3V/5V logic controllers, while low Qg (13.2nC) and fast switching times (tR = 2.5ns, tF = 4.5ns) support high-frequency (>500kHz) operation in automotive DC-DC topologies.
The device features symmetrical internal structure: each channel has independent source (S1/S2), gate (G1/G2), and drain (D1/D2) terminals with shared thermal pad. Its RDS(ON) remains stable up to +175°C (≤10mΩ at TJ = +175°C, VGS = 10V), and Ciss/Coss/Crss values (1083pF / 621pF / 21pF) are optimized for ZVS/ZCS soft-switching implementations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Supports 12V/24V automotive bus systems with margin against load-dump transients |
| RDS(ON) | 4.3–5.5mΩ @ VGS = 10V - Enables ≤1.5W conduction loss per channel at 79A, critical for thermally constrained modules |
| ID (TC = 25°C) | 79A - Sustains high-current output stages without external heatsinking when mounted on 2oz copper PCB |
| TJ Range | −55°C to +175°C - Qualified for under-hood environments and battery management systems requiring extended thermal range |
| Qg | 13.2nC - Reduces gate driver power demand and enables efficient operation with low-side drivers like DIODES AP21xx series |
| EAS | 20.6mJ - Confirmed avalanche energy rating ensures survivability during inductive turn-off faults in motor control or converter applications |
Pinout & Package
Package: PowerDI5060-8/SWP (Type UXD), surface-mount, thermally enhanced with exposed drain pad (D1/D2 tied internally to thermal pad). Molded green compound, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S1) | Source of Channel 1 | Low-side return path for first MOSFET; electrically isolated from S2 for independent gate control |
| 2 (G1) | Gate of Channel 1 | Control input for first channel; requires <2.0–3.5V threshold to initiate conduction |
| 3 (D1) | Drain of Channel 1 | High-side connection point; bonded to exposed thermal pad for low RθJC = 2.5°C/W |
| 4 (D2) | Drain of Channel 2 | Second high-side node; shares thermal pad with D1 but electrically isolated |
| 5 (G2) | Gate of Channel 2 | Independent control input for second channel; identical threshold and drive requirements as G1 |
| 6 (S2) | Source of Channel 2 | Return path for second channel; enables true dual half-bridge or dual-phase synchronous rectifier configuration |
| 7–8 (Exposed Pad) | Common Drain Thermal Pad | Primary heat dissipation path; must be soldered to ≥1in² 2oz copper pour for rated 60W PD at TC = 25°C |

Use Scenario: High-efficiency 15W–30W Qi-compliant transmitter stage operating at 100–205kHz. IC Role / Device Role / Timing Role: Dual-channel synchronous switch driving series-resonant tank; one channel controls upper leg, the other lower leg in half-bridge topology. Use Value: Low RDS(ON) and fast switching reduce conduction and switching losses, achieving >93% system efficiency at full load while maintaining thermal safety at +105°C ambient. |
Use Scenario: 48V-to-12V bidirectional DC-DC converter in 48V mild-hybrid vehicles. IC Role / Device Role / Timing Role: Primary-side synchronous rectifier in phase-shifted full-bridge; dual channels implement complementary high-side/low-side switching per leg. Use Value: Matched RDS(ON) and thermal coupling between channels ensure balanced current sharing and eliminate need for external current-sense resistors. |
| On-Board Charger (OBC) Auxiliary Supply | Electric Power Steering (EPS) Motor Driver |
|
Use Scenario: 3.3V/5V auxiliary supply derived from main HV bus using flyback or forward converter. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier pair replacing Schottky diodes to improve light-load efficiency and reduce thermal footprint. Use Value: 5.5mΩ RDS(ON) cuts secondary conduction loss by 65% vs. 40V Schottky, enabling >85% efficiency at 10% load and eliminating forced-air cooling. |
Use Scenario: Compact 3-phase inverter stage for 12V EPS motor control with integrated gate drivers. IC Role / Device Role / Timing Role: Half-bridge building block per phase; two DMTH45M5SPDWQ units provide six switches for full 3-phase bridge. Use Value: Wettable flank leads ensure AOI-compatible solder joints in high-vibration environments, while +175°C rating supports operation adjacent to motor housing without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon BSC028N06NS3 | 60V VDSS, 2.8mΩ RDS(ON), PG-TSDSON-8 package, no wettable flanks | Higher voltage margin but lacks AEC-Q101 documentation for PPAP submission; not qualified for +175°C operation | Select only if system requires >40V blocking and thermal environment stays below +150°C |
| Vishay SI7973DP-T1-GE3 | 40V VDSS, 6.5mΩ RDS(ON), PowerPAK SO-8L, AEC-Q101 qualified, no UIS production test | Lower thermal performance (RθJC = 3.5°C/W), no 100% UIS screening, and no wettable flank inspection capability | Acceptable for non-safety-critical 12V body electronics where AOI and extreme thermal reliability are not mandated |
Compared with BSC028N06NS3 and SI7973DP-T1-GE3, DMTH45M5SPDWQ-13 uniquely combines AEC-Q101 PPAP readiness, +175°C operation, 100% UIS testing, and wettable flank leads-making it the only option qualified for safety-critical, thermally aggressive automotive power conversion where zero-defect assembly and transient survivability are mandatory.

FAQ
Is DMTH45M5SPDWQ-13 pin-compatible with standard SO-8 or PowerPAK packages?
No. DMTH45M5SPDWQ-13 uses the proprietary PowerDI5060-8/SWP (Type UXD) footprint with 1.27mm pitch and asymmetric lead geometry. Its pad layout differs significantly from SO-8 (1.27mm pitch, symmetric) and PowerPAK SO-8L (1.27mm pitch, no wettable flanks). PCB redesign is required for migration.
What is the maximum recommended gate drive voltage for reliable long-term operation?
The absolute maximum gate-source voltage is ±20V, but Diodes specifies 10V as the nominal drive condition for RDS(ON) characterization and lifetime validation. Operation at 12V is permissible but increases gate oxide stress; sustained >12V drive may accelerate wear-out in high-temperature automotive applications.
Does the device include integrated body diodes, and what is their forward voltage?
Yes-each channel includes a monolithic body diode with typical VSD = 0.9V at IS = 25A and VGS = 0V. These diodes are rated for continuous forward current up to 79A and pulsed current up to 316A, supporting synchronous rectification and freewheeling functions without external diodes.
How does the wettable flank feature impact reflow profile and solder inspection?
The side-wettable leads require standard SnAgCu reflow profiles (peak 245°C, 60s above 220°C) and form visible solder fillets on all four side surfaces. This enables 100% automated optical inspection (AOI) of solder joint integrity-unlike conventional gull-wing leads-reducing escape risk in automotive Class A assemblies.
