Product details
Overview
DMTH45M5SPSWQ from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in PowerDI5060-8/SWP package, rated for 40V VDSS, 5.5mΩ RDS(ON) @ 10V VGS, and 86A ID at TC = +25°C. It operates up to +175°C junction temperature and supports high-frequency switching in automotive DC-DC converters.
For engineers reviewing the DMTH45M5SPSWQ datasheet, DMTH45M5SPSWQ pinout, DMTH45M5SPSWQ application, or DMTH45M5SPSWQ equivalent, this part is selected for synchronous rectification, high-ambient-temperature power stages, and PPAP-capable automotive subsystems requiring robust UIS performance and wettable flank inspection capability.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching with Ciss = 1083pF and Qg = 13.2nC at VDS = 20V. Its body diode exhibits tRR = 61.3ns and QRR = 52.1nC under 25A/100A/μs conditions.
The device integrates an exposed drain pad for thermal conduction (RθJC = 2.0°C/W), supports ±20V gate drive, and delivers stable RDS(ON) across -55°C to +175°C with normalized drift ≤1.8× at max TJ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage before avalanche onset; defines safe operation in 24V automotive systems with transients. |
| RDS(ON) | 5.5mΩ @ 10V - Confirmed on-resistance at standard gate drive; enables <1.4W conduction loss at 25A. |
| ID (TC = 25°C) | 86A - Continuous drain current rating at case temperature 25°C; sets thermal design baseline for heatsink sizing. |
| Qg | 13.2nC - Total gate charge required for full turn-on; determines driver strength requirement and switching loss trade-off. |
| tRR | 61.3ns - Body diode reverse-recovery time; critical for synchronous rectifier efficiency and EMI control in hard-switched topologies. |
| TJ Max | +175°C - Maximum junction temperature rating; allows operation in engine bay or powertrain modules without derating. |
| EAS | 20.6mJ - Single-pulse avalanche energy rating; validates ruggedness against inductive switching stress in motor drives. |
Pinout & Package
Package: PowerDI5060-8/SWP (Type UX), surface-mount, thermally enhanced with exposed drain pad and wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Source | Low-side return path; electrically tied to three internal source terminals for reduced parasitic inductance. |
| 2 | Drain | Main power output node; connected to large-area exposed copper pad for thermal dissipation and current handling. |
| 3 | Source | Redundant source connection; improves current sharing and reduces bond wire resistance in parallel configurations. |
| 4 | Source | Third source terminal; enhances layout symmetry and minimizes source inductance in high-di/dt applications. |
| 5 | Gate | Control input; requires <13.2nC charge for full enhancement; sensitive to ESD (±20V rating). |
| 6 | Drain | Second drain connection; shares current with Pin 2 and Pin 7–8 to distribute thermal load across package. |
| 7 | Drain | Third drain terminal; contributes to low RθJC (2.0°C/W) via direct thermal path to PCB copper. |
| 8 | Drain | Fourth drain connection; enables high-current routing while maintaining mechanical stability on FR-4 boards. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification & PPAP support | Validated for automotive production use with documented change control, IATF 16949 manufacturing, and zero defect sampling plans. |
| 100% UIS tested in production | Every unit undergoes unclamped inductive switching stress test (L = 0.1mH, IAS = 20.3A), ensuring field reliability in motor and solenoid drivers. |
| Wettable flank leads | Matte tin-annealed terminals enable automated AOI detection of solder joint integrity-critical for safety-critical automotive assembly lines. |
| +175°C continuous operation | Guaranteed parametric performance up to maximum junction temperature; eliminates need for external thermal derating in under-hood designs. |
| Low Ciss/Coss ratio | Ciss = 1083pF, Coss = 621pF - Enables efficient ZVS/ZCS implementation and reduces Miller-induced shoot-through risk. |

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 |
|---|---|---|---|
| STL220N4F7AG | RDS(ON) = 3.7mΩ @ 10V, but VDSS = 40V same; Qg = 19.5nC (48% higher); no wettable flank. | Higher gate drive demand increases controller complexity; unsuitable for AOI-dependent automotive lines. | Select only if lowest possible conduction loss is prioritized over manufacturability and switching loss. |
| IXTP44N10P | TO-220 package; RDS(ON) = 22mΩ @ 10V; TJ max = +175°C; no AEC-Q101 qualification. | Requires manual soldering and thermal interface material; not PPAP-ready for Tier 1 OEMs. | Acceptable for non-safety-critical industrial prototypes, but not for production automotive ECUs. |
Compared with STL220N4F7AG and IXTP44N10P, DMTH45M5SPSWQ uniquely balances ultra-low RDS(ON), AEC-Q101 compliance, wettable flank inspection, and integrated thermal performance-making it the only choice for volume automotive power stages where manufacturability, reliability, and efficiency are jointly constrained.

FAQ
What is the maximum gate-source voltage rating for DMTH45M5SPSWQ?
The absolute maximum gate-source voltage is ±20V, per the datasheet's "Maximum Ratings" table. Exceeding this value risks permanent gate oxide damage. Recommended gate drive is 10V for full enhancement, with 4.5V minimum for guaranteed turn-on at elevated temperatures.
Does DMTH45M5SPSWQ require a gate resistor for safe operation?
Yes-a series gate resistor (typically 3.5Ω, as used in the datasheet's switching time test conditions) is required to control dV/dt, limit peak gate current, and prevent oscillation. Without it, ringing and unintended turn-on due to Miller effect may occur, especially at high di/dt.
Can DMTH45M5SPSWQ be used in parallel configurations?
Yes-the device features multiple source and drain terminals (Pins 1,3,4 and 2,6,7,8) and positive RDS(ON) temperature coefficient, enabling stable current sharing. Layout symmetry and matched gate drive paths are essential to avoid imbalance.
Is the PowerDI5060-8/SWP package lead-free and RoHS compliant?
Yes-DMTH45M5SPSWQ uses matte tin annealed over copper leadframe and green molding compound, meeting EU RoHS 2015/863/EU (RoHS 3) with exemptions applied, and is halogen- and antimony-free per Diodes' definition (<900ppm Br, <900ppm Cl, <1000ppm Sb).
