Product details

Overview

DMTH43M8LPS from Diodes Incorporated is a 40V, 100A N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for continuous operation at +175°C junction temperature, with R_DS(ON) = 3.3 mΩ @ V_GS = 10V and 100% unclamped inductive switching (UIS) rating of 13.2 A / 87 mJ - deployed in high-reliability BLDC motor drives and automotive-grade DC-DC converters.

For engineers reviewing the DMTH43M8LPS datasheet, DMTH43M8LPS pinout, DMTH43M8LPS application, or DMTH43M8LPS equivalent, this page delivers verified thermal, switching, and conduction parameters - including R_DS(ON) vs. temperature behavior, gate charge profile (Q_G = 38.5 nC @ 10V), and SOA-limited pulse capability - to support thermal design, gate driver sizing, and high-temperature system validation.

Technical Context

This MOSFET employs trench-gate silicon technology optimized for low R_DS(ON) while preserving fast switching (t_r = 5.7 ns, t_f = 11 ns) and low gate charge (Q_GD = 6.9 nC). Its 1.8 °C/W R_θJC enables high-power dissipation when mounted on thermally enhanced PCBs or heatsinks.

The device integrates a robust body diode with t_RR = 35.4 ns and Q_RR = 32.9 nC, supporting synchronous rectification and hard-switched topologies. JEDEC-qualified per AEC-Q standards, it meets automotive reliability requirements without requiring separate qualification documentation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum drain-source blocking voltage before avalanche onset; sets upper limit for bus voltage in 12–24 V systems.
R_DS(ON)	3.3 mΩ @ V_GS = 10V - Enables <1.3 W conduction loss at 20 A, critical for efficiency in high-current load switches.
I_D (T_C = 25°C)	100 A - Continuous current rating under case-cooled conditions; defines thermal derating baseline for heatsink design.
Q_G	38.5 nC @ V_GS = 10V - Determines gate driver peak current requirement (~13 A for 3 Ω series resistance and 10 ns rise time).
R_θJC	1.8 °C/W - Junction-to-case thermal resistance; allows direct thermal interface to heatsink or copper plane for >80 W power handling.
E_AS	87 mJ - Avalanche energy rating; supports reliable operation during inductive turn-off transients in motor control without external snubbers.
T_J max	+175°C - Maximum junction temperature; enables deployment in engine bay, under-hood, or industrial enclosures without active cooling.

Pinout & Package

Package: PowerDI5060-8 - surface-mount, thermally enhanced 8-pin leadless package with exposed drain pad (pins 2–5 and 7–8 are internally connected to drain; pins 1 and 6 are source; pin 3 is gate). UL 94V-0 molded compound, matte tin annealed over copper leadframe, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1, Pin 6	Source (S)	Low-side return path; electrically tied to internal source terminals; requires low-inductance PCB routing for switching stability.
Pin 3	Gate (G)	Control input; 2.54 Ω gate resistance limits dV/dt-induced shoot-through; requires <10 Ω driver impedance for optimal switching.
Pins 2,4,5,7,8	Drain (D)	High-current power node; all pins internally bonded to exposed drain pad - must be soldered to large copper area for thermal and current handling.

Key Features

Feature	Design Value
+175°C rated operation	Enables use in under-hood automotive, industrial motor drives, and high-ambient-temperature power supplies without thermal throttling.
100% UIS tested	Guarantees robustness against inductive energy dump during fault conditions - eliminates need for external avalanche protection in BLDC inverters.
Low R_DS(ON) × Q_G figure-of-merit	12.8 mΩ·nC - balances conduction and switching losses for high-efficiency 100–500 kHz DC-DC converters.
Lead-free, halogen-free "Green" construction	Complies with RoHS 3 (2015/863/EU) and automotive ELV directives; <900 ppm Br/Cl, <1000 ppm Sb - supports eco-design certification.
AEC-Q qualified	Validated per JEDEC standards for automotive applications - no additional qualification required for Tier-1 supplier BOMs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel power MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPB033N04LGATMA1	R_DS(ON) = 3.3 mΩ @ 10V but rated only to +150°C; higher Q_G = 49 nC; TO-263-7 package.	Lacks +175°C rating and UIS testing; unsuitable for under-hood automotive or high-temp industrial use.	Select only if board space allows TO-263 footprint and ambient temperature remains ≤125°C.
STL220N4LF8AG	R_DS(ON) = 2.2 mΩ @ 10V but no AEC-Q qualification; PowerFLAT 5x6 package; lower R_θJC = 1.5 °C/W.	Higher conduction efficiency but unqualified for automotive; not validated for 100% UIS stress.	Prefer for non-automotive high-efficiency DC-DC where thermal margin exceeds 20°C and reliability testing is customer-owned.

Compared with IPB033N04LGATMA1 and STL220N4LF8AG, DMTH43M8LPS uniquely combines +175°C operation, full UIS validation, and AEC-Q compliance in a compact PowerDI5060-8 package - making it the only drop-in solution for automotive BLDC inverters and industrial PDUs requiring guaranteed high-temperature robustness.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The DMTH43M8LPS supports 82 A continuous drain current at T_C = +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PowerDI5060-8 package and must be applied when heatsink or PCB thermal resistance exceeds 1.8 °C/W total junction-to-ambient path.

Does DMTH43M8LPS require a gate resistor for safe operation?

Yes - a gate resistor between 5 Ω and 15 Ω is recommended to control dV/dt and prevent parasitic oscillation during switching. The device's 2.54 Ω intrinsic gate resistance alone is insufficient for stable operation with typical gate drivers; external resistance ensures t_r/t_f remain within datasheet-specified 5.7 ns/11 ns bounds.

Can DMTH43M8LPS replace older PowerDI5060-8 MOSFETs like DMTH6016LPS?

No - DMTH6016LPS has V_DSS = 60 V and R_DS(ON) = 1.6 mΩ, making it incompatible for direct substitution. DMTH43M8LPS is optimized for 40 V systems with higher current density and +175°C rating; replacement requires full circuit revalidation due to different threshold voltage (1–2.5 V vs. 2–4 V) and SOA boundaries.

Is the PowerDI5060-8/SWP variant pin-compatible with the standard PowerDI5060-8?

Yes - both variants share identical pin numbering, terminal functions, and mechanical outline. The SWP (Type UX) version features modified land pattern dimensions (e.g., D2a = 3.98 mm vs. D2 = 3.90 mm) and slightly adjusted leadframe geometry, but electrical connectivity and thermal performance are functionally equivalent per Diodes' packaging documentation.
