Product details

Overview

DMTH8028LPSWQ-13 from Diodes Incorporated is an AEC-Q101-qualified 80V N-channel enhancement-mode MOSFET in PowerDI5060-8 (SWP) package, delivering 25 mΩ R_DS(ON) at V_GS = 10 V and 41.7 A continuous drain current at T_C = +25°C. It supports automotive synchronous rectification and DC-DC power management with 175°C maximum junction temperature and wettable flank terminals for automated optical inspection.

For engineers reviewing the DMTH8028LPSWQ-13 datasheet, DMTH8028LPSWQ-13 pinout, DMTH8028LPSWQ-13 application, or DMTH8028LPSWQ-13 equivalent, key selection criteria include its 80V BVDSS rating, low 25 mΩ on-resistance at 10 V gate drive, AEC-Q101 qualification, PPAP capability, and thermal performance under high-temperature automotive operating conditions.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in high-efficiency automotive power stages. Its 100% production-tested UIS capability ensures robustness against inductive load transients, while the integrated body diode exhibits 25.5 ns reverse recovery time and 20.6 nC Q_RR at 7.5 A/100 A/μs.

The device operates across -55°C to +175°C junction temperature range and features 2.3°C/W R_θJC for direct thermal coupling to PCB copper pads. Gate charge parameters-10.4 nC total Q_g at V_GS = 10 V and 2.4 nC Q_gd-support efficient hard-switching in 40 V nominal DC-DC converters.

Key Specifications

Parameter	Value and Actual Design Meaning
BVDSS	80 V - Withstands up to 80 V drain-source voltage before avalanche breakdown, enabling use in 48 V automotive systems with margin.
RDS(ON)	25 mΩ @ VGS = 10 V - Low conduction loss at full gate drive, reducing I²R heating in high-current power paths.
ID (TC = +25°C)	41.7 A - Continuous drain current rating when case temperature is maintained at 25°C, supporting high-power density designs.
Qg / Qgd	10.4 nC / 2.4 nC - Enables fast turn-on/turn-off with moderate gate driver strength; low Qgd improves hard-switching EMI behavior.
TJ max	+175°C - Rated for under-hood automotive environments where ambient temperatures exceed 125°C.
EAS	23.4 mJ - Energy-handling capability during unclamped inductive switching events, critical for reliability in motor control and solenoid drivers.

Applications

Synchronous Rectifier in Automotive DC-DC Converters

LED Backlight Driver for Instrument Clusters

Use Scenario: Replaces Schottky diodes in 12 V → 5 V/3.3 V buck converters powering vehicle ECUs and domain controllers.

IC Role / Device Role / Timing Role: High-side or low-side synchronous rectifier switch operating at 250–500 kHz with zero-voltage switching assist.

Use Value: Reduces conduction loss by >40% vs. 45 V Schottky, lowering thermal stress and enabling smaller heatsinks in space-constrained modules.

Use Scenario: Drives LED strings in digital instrument clusters requiring PWM dimming and overvoltage protection.

IC Role / Device Role / Timing Role: Low-side current sink switch controlled by MCU GPIO with fast turn-off (<10 ns fall time) for precise brightness control.

Use Value: 25 mΩ R_DS(ON) minimizes voltage drop across current-sense resistor, improving dimming linearity and thermal stability at 175°C ambient.

Automotive Body Control Module (BCM) Power Management

12 V Start-Stop System Load Switch

Use Scenario: Controls power to auxiliary loads (window lifts, seat motors, HVAC fans) in BCMs with integrated diagnostics.

IC Role / Device Role / Timing Role: High-side load switch with integrated current sensing and short-circuit protection feedback.

Use Value: 41.7 A ID rating and 175°C TJ max allow direct integration into BCM PCBs without external heatsinks, reducing BOM count.

Use Scenario: Isolates battery from starter motor auxiliary circuits during cranking to prevent brownout in infotainment systems.

IC Role / Device Role / Timing Role: Robust load switch activated by CAN-controlled MCU with fast response (<20 ns propagation delay).

Use Value: 80 V BVDSS withstands load-dump transients up to 65 V, eliminating need for external TVS clamping in ISO 7637-2 compliant designs.

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
STL135N8LH5AG	80 V, 1.35 mΩ R_DS(ON), PowerFLAT 5x6; lower on-resistance but higher Q_g (32 nC)	Better for ultra-high-efficiency 48 V systems; less suitable for 12 V cost-sensitive BCMs due to price and gate drive demand	Select when thermal budget is tighter than gate drive capability; verify layout compatibility with larger footprint.
IXTP50N10T	100 V, 18 mΩ R_DS(ON), TO-220AB; higher voltage rating but no AEC-Q101 qualification or wettable flanks	Acceptable for industrial DC-DC but not for automotive production due to missing PPAP and IATF 16949 traceability	Use only in non-automotive prototypes or legacy industrial upgrades where qualification is not required.

Compared with STL135N8LH5AG and IXTP50N10T, DMTH8028LPSWQ-13 uniquely balances AEC-Q101 compliance, wettable flank AOI support, and optimized 25 mΩ/10.4 nC trade-off for mainstream 12 V/48 V automotive power stages-making it the preferred choice for volume production where qualification, manufacturability, and thermal performance are jointly constrained.

FAQ

What is the maximum allowable gate-source voltage for DMTH8028LPSWQ-13?

The absolute maximum gate-source voltage is ±20 V per the datasheet's Maximum Ratings table. Exceeding this value risks permanent gate oxide damage. For reliable operation, gate drive should be limited to 10 V for full R_DS(ON) performance or 4.5 V for logic-level compatibility, both well within the safe operating range.

Does DMTH8028LPSWQ-13 require a gate resistor for automotive applications?

Yes-a series gate resistor (typically 2.7 Ω to 10 Ω) is recommended to dampen ringing and control dV/dt during switching. The device's 1.4 Ω intrinsic gate resistance and 10.4 nC total gate charge make it sensitive to parasitic oscillation without proper gate drive impedance matching, especially in noisy automotive harness environments.

How does the wettable flank feature improve manufacturing yield?

The wettable flank design exposes vertical sidewalls of all eight leads, allowing automated optical inspection (AOI) systems to detect solder fillet height, wetting angle, and bridging defects with >99.5% accuracy. This eliminates reliance on X-ray for hidden-joint verification and reduces rework rates in high-volume automotive SMT lines certified to IATF 16949.

Can DMTH8028LPSWQ-13 replace a TO-252 DPAK MOSFET in existing designs?

Yes, with PCB layout revision: PowerDI5060-8 has identical thermal pad area and compatible 1.27 mm lead pitch, but requires updated stencil aperture and footprint per Diodes' suggested pad layout (Document DS42280, Page 7). Thermal performance improves due to lower R_θJC (2.3°C/W vs. ~3.5°C/W for DPAK), enabling higher current in same board area.
