Product details

Overview

DMTH32M5LPSQ-13 from Diodes Incorporated is a 30V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI5060-8 package, delivering 2.2mΩ R_DS(ON) at V_GS = 10V and 170A continuous drain current at T_C = +25°C. It is AEC-Q101 qualified, PPAP-capable, and designed for high-reliability automotive power switching in engine management, body control, and DC-DC converters.

For engineers reviewing the DMTH32M5LPSQ-13 datasheet, DMTH32M5LPSQ-13 pinout, DMTH32M5LPSQ-13 application, or DMTH32M5LPSQ-13 equivalent, key selection criteria include its 175°C junction rating, 100% production-tested unclamped inductive switching (UIS), low 2.2mΩ on-resistance, <1.1mm profile, and AEC-Q101 qualification for automotive-grade thermal and reliability assurance.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) and fast switching in high-current automotive power stages. Its internal structure features an 8-terminal PowerDI5060-8 layout with dual-source/drain paralleling to reduce conduction loss and improve current sharing.

The device supports gate drive at 4.5V (R_DS(ON) = 3.2mΩ) and 10V (R_DS(ON) = 2.2mΩ), with 1.6–3.0V gate threshold voltage and 68nC total gate charge at 10V. Its 1.5°C/W R_θJC enables high-power dissipation when mounted on thermally enhanced PCBs with exposed drain pad soldering.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30V - Maximum blocking voltage for 12V/24V automotive battery rail protection and switching
R_DS(ON) @ 10V	2.2mΩ - Enables ≤0.3W conduction loss at 140A, critical for high-efficiency DC-DC converter primary switches
I_D (T_C = 25°C)	170A - Supports high-current motor drivers and starter solenoid control without external heatsinking
T_J max	+175°C - Rated for under-hood environments including engine bay and transmission control units
UIS Rating	100% production tested - Guarantees robustness against inductive kickback in relay and solenoid drive circuits
Package	PowerDI5060-8 - Exposed drain pad and 0.9–1.1mm height enable thin-profile, high-thermal-conductivity mounting
Q_g @ 10V	68nC - Determines gate driver sizing for ≤37.5ns turn-off delay and efficient 100kHz+ switching
AEC-Q101	Qualified - Meets stress test requirements for automotive electronics per IATF 16949 manufacturing

Pinout & Package

PowerDI5060-8 is a surface-mount, thermally enhanced 8-pin package with exposed drain pad (pins 2, 4, 6, 8 connected to drain), dual source terminals (pins 1, 3, 5, 7), and single gate terminal (pin 1). The low 1.5°C/W junction-to-case thermal resistance relies on full-solder coverage of the bottom-side drain pad.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (S/G)	Source / Gate	Shared terminal: Source connection (pins 1,3,5,7 all tied internally); gate signal input via this pin
Pins 2, 4, 6, 8	Drain	Internally paralleled drain nodes - must be soldered to large copper pour for thermal and current handling
Pins 1, 3, 5, 7	Source	Four-source configuration reduces source inductance and improves current sharing in high-di/dt applications
Bottom Pad	Drain (Thermal)	Exposed metal pad - primary thermal path; requires ≥90% solder coverage for rated 100W power dissipation

Key Features

Feature	Design Value
175°C operation	Enables placement in high-ambient zones (e.g., near engines or inverters) without derating or forced cooling
100% UIS tested	Eliminates need for external snubbers in inductive load switching, reducing BOM count and board space
<1.1mm profile	Supports ultra-thin modules such as compact ADAS ECUs and integrated seat control units
Low 2.2mΩ R_DS(ON)	Reduces conduction losses by >35% vs. comparable 30V MOSFETs, extending battery life in 12V start-stop systems
AEC-Q101 + PPAP	Validates full automotive supply chain traceability, change control, and failure mode analysis for Tier-1 programs

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
STL220N3LLH6	30V, 2.0mΩ @ 10V, 220A, PowerFLAT 5x6	Higher current rating but larger footprint and no AEC-Q101 documentation in public datasheet	Prefer when peak current exceeds 170A and board area allows 5x6mm package
IPB180N03L-H0	30V, 1.8mΩ @ 10V, 180A, TO-263-7	TO-263-7 package requires through-hole reflow or mechanical retention; higher R_θJA than PowerDI5060-8	Choose when legacy TO-263 layout exists and thermal interface to heatsink is available

Compared with STL220N3LLH6 and IPB180N03L-H0, DMTH32M5LPSQ-13 offers superior thermal profile (<1.1mm height), verified AEC-Q101 compliance with PPAP support, and optimized pinout for low-inductance PCB routing-making it preferred for space-constrained, high-reliability automotive modules where qualification traceability is mandatory.

FAQ

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

The DMTH32M5LPSQ-13 supports 120A continuous drain current at T_C = +100°C, as specified in its Absolute Maximum Ratings table. This derating reflects thermal limits of the PowerDI5060-8 package and ensures safe operation in under-hood applications where ambient temperatures exceed 85°C.

Does this MOSFET require a gate resistor for automotive PWM applications?

Yes-a gate resistor (typically 3–10Ω) is recommended to control dV/dt and prevent parasitic oscillation during high-speed switching. The device's 0.6Ω intrinsic gate resistance and 68nC total gate charge make external gate resistance essential for stable 100kHz+ operation in DC-DC converters and motor drives.

Is the PowerDI5060-8 package lead-free and RoHS compliant?

Yes-the DMTH32M5LPSQ-13 uses matte tin annealed over copper leadframe and conforms to EU RoHS directives 2011/65/EU and 2015/863/EU. It is also halogen- and antimony-free ("Green" per Diodes' definition), with bromine <900ppm, chlorine <900ppm, and antimony <1000ppm.

How is the 100% UIS testing performed and what does it guarantee?

Each DMTH32M5LPSQ-13 unit undergoes 100% unclamped inductive switching (UIS) test in production using L = 0.1mH, I_AS = 50A, and E_AS = 140mJ. This validates ruggedness against real-world inductive transients in solenoid and relay circuits, eliminating field failures due to avalanche-induced degradation.
