Product details
Overview
DMTH45M5LPSWQ-13 from Diodes Incorporated is an AEC-Q101 qualified 40V N-channel enhancement-mode MOSFET in PowerDI5060-8 (SWP) package, delivering 5.5 mΩ RDS(ON) at VGS = 10 V and 86 A continuous drain current at TC = +25°C. It operates up to +175°C junction temperature and supports high-frequency switching in automotive DC-DC converters and synchronous rectifiers.
For engineers reviewing the DMTH45M5LPSWQ-13 datasheet, DMTH45M5LPSWQ-13 pinout, DMTH45M5LPSWQ-13 application, or DMTH45M5LPSWQ-13 equivalent, key selection criteria include its wettable flank package for automated optical inspection, 100% production-tested UIS robustness, low Qg (13.9 nC @ 10 V), and AEC-Q101 qualification with PPAP support.
Technical Context
This MOSFET uses a trench-gate silicon process optimized for low conduction loss and fast switching in high-temperature automotive power stages. Its RDS(ON) remains stable across -55°C to +175°C, with normalized on-resistance variation ≤1.8× over that range at VGS = 10 V.
The device integrates a low-VSD body diode (0.82 V typ. @ 25 A, VGS = 0 V) and exhibits low Crss (30 pF) and Ciss (978 pF), enabling efficient hard-switching operation in 48V/12V bidirectional converters and motor control half-bridges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum blocking voltage for 12V/48V automotive bus-level switching |
| RDS(ON) @ 10 V | 5.5 mΩ max - Enables <1.4 W conduction loss at 86 A, critical for thermal management in compact modules |
| ID (TC = 25°C) | 86 A - Supports high-current power delivery in engine control units and ADAS domain controllers |
| Qg @ 10 V | 13.9 nC - Reduces gate drive power and enables >500 kHz PWM operation with standard drivers |
| tRR | 59 ns - Minimizes reverse recovery loss during synchronous rectification in buck converters |

| 3 (S) | Source | Parallel source connection to reduce resistance and improve current sharing |
| 4 (G) | Gate | Control input; requires <2 Ω series resistance to damp ringing due to low Rg (1.5 Ω) |
| 5 (D) | Drain | Second drain terminal for enhanced current handling and thermal spreading |
| 6 (D) | Drain | Third drain terminal; shares load with pins 2 and 5 to lower effective RDS(ON) |
| 7 (S) | Source | Additional source connection to minimize source inductance in high-dI/dt switching |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N4F7AG | 40V, 2.2 mΩ @ 10 V, PowerFLAT 5x6; higher RDS(ON) tempco (+0.4%/°C vs. +0.25%/°C) | Requires larger gate driver due to 25 nC Qg; not qualified to AEC-Q101 Grade 0 | Prefer for cost-sensitive non-safety-critical 12V loads where ultra-low RDS(ON) dominates |
| IPB180N04S4-02 | 40V, 1.8 mΩ @ 10 V, TO-leadless; no wettable flank; 150°C max TJ | Lacks +175°C rating and UIS production test; unsuitable for under-hood ECU modules | Use only in cabin-mounted modules with active cooling and <150°C ambient |

FAQ
What is the maximum allowable PCB copper area for thermal performance?
The datasheet specifies thermal resistance RθJC = 2.0°C/W when mounted on a 1-inch square 2oz copper plate. For optimal performance, use ≥250 mm² exposed drain pad area with ≥6 thermal vias (0.3 mm diameter) connecting to inner ground planes. Larger copper areas reduce RθJA below the nominal 42°C/W value.
Does the device support gate voltages below 4.5 V in logic-level operation?
No-VGS(TH) ranges from 1.2 V to 2.3 V, but RDS(ON) is not characterized below 4.5 V. At VGS = 3.3 V, typical RDS(ON) exceeds 15 mΩ, causing excessive conduction loss. Use only with 4.5 V or higher gate drive for rated performance.
How is the wettable flank feature implemented in the PowerDI5060-8 package?
The side walls of pins 1–8 extend 0.125 mm below the package body with matte tin finish, allowing automated optical inspection systems to capture solder fillet height and wetting angle. This eliminates reliance on X-ray for lead coplanarity and solder joint integrity validation in automotive assembly lines.
Is the body diode suitable for reverse polarity protection?
Yes-the body diode has 86 A continuous forward rating and 344 A pulsed capability. However, its VSD (0.82 V typ.) causes higher power loss than dedicated ideal diode controllers. Use only where simplicity outweighs efficiency requirements, such as backup power path in telematics modules.
