Diodes Incorporated DMTH8028LFVW-13

Overview

DMTH8028LFVW-13 from Diodes Incorporated is an 80V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 27A continuous drain current at TC = +25°C and R_DS(ON) of 25 mΩ @ V_GS = 10V. It serves as a high-efficiency power switch in DC-DC converters and backlighting circuits, with 100% production-tested UIS robustness and wettable flank terminals for automated optical inspection.

For engineers reviewing the DMTH8028LFVW-13 datasheet, DMTH8028LFVW-13 pinout, DMTH8028LFVW-13 application, or DMTH8028LFVW-13 equivalent, key selection criteria include its 4.0°C/W R_θJC, 21A ID at V_GS = 4.5V, 108A pulsed drain rating, 23.4mJ EAS avalanche energy, and thermally optimized PowerDI3333-8/SWP (Type UX) package with exposed drain pad.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) while preserving fast switching performance-evidenced by 10.4 nC total gate charge at V_GS = 10V and 7.1 ns turn-on delay. Its safe operating area (SOA) is characterized up to 175°C junction temperature with single-pulse limits extending to 100 ms at 40V V_DS.

The device integrates a body diode with 28.5 ns reverse recovery time and 21.7 nC Q_RR, enabling synchronous rectification in buck converters. Thermal design leverages a 4.0°C/W junction-to-case path via the exposed drain pad, supported by validated FR-4 PCB layouts with 2 oz copper and thermal bias to a 1-inch² copper plate.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The DMTH8028LFVW-13 is rated for continuous operation up to T_J = +175°C, verified across its full Safe Operating Area (SOA) curve. This rating applies under steady-state thermal conditions with appropriate PCB copper thermal bias and is validated by production testing per JESD22-A108.

Does this MOSFET require a gate resistor for reliable switching?

A gate resistor is recommended to dampen ringing and limit peak gate current-especially given its 10.4 nC total gate charge and 1.1 Ω intrinsic gate resistance. For 500 kHz operation with a 5V MCU driver, a 4.7 Ω series resistor optimizes switching speed versus EMI and shoot-through risk.

Can the DMTH8028LFVW-13 be used in synchronous rectification mode?

Yes-the integrated body diode has t_RR = 28.5 ns and Q_RR = 21.7 nC, enabling use as a synchronous rectifier in buck converters up to 1 MHz. However, external FET control timing must account for its V_GS(TH) range (1.3–2.5 V) to avoid cross-conduction.

Is the PowerDI3333-8/SWP (Type UX) package compatible with standard reflow profiles?

Yes-the package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity Level 1 and supports standard lead-free reflow profiles (peak 260°C). Its matte tin finish ensures solderability per MIL-STD-202, Method 208, and the wettable flanks enable post-reflow AOI verification of side-wall solder joints.
