Diodes Incorporated DMNH6035SPDW-13

Overview

DMNH6035SPDW from Diodes Incorporated is a 60V, 33A N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for operation up to +175°C, with R_DS(ON) = 35 mΩ @ V_GS = 10 V and 44 mΩ @ V_GS = 4.5 V. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters and backlighting power stages.

For engineers reviewing the DMNH6035SPDW datasheet, DMNH6035SPDW pinout, DMNH6035SPDW application, or DMNH6035SPDW equivalent, key selection criteria include its wettable flank package for automated optical inspection, 100% production-tested UIS capability, and thermal performance validated to JEDEC reliability standards under high ambient temperature conditions.

Technical Context

This dual-drain, dual-source, dual-gate MOSFET integrates two identical N-channel channels in a single PowerDI5060-8 (SWP) package with exposed drain pads for enhanced thermal dissipation. Its gate threshold voltage (1–3 V) enables compatibility with 3.3 V and 5 V logic-level drive, while low input capacitance (C_iss = 879 pF) supports high-frequency switching up to several hundred kHz.

The device features an integrated body diode with reverse recovery time t_RR = 28 ns and Q_RR = 28 nC at I_F = 20 A / di/dt = 100 A/μs, supporting synchronous rectification and hard-switched topologies. Thermal resistance R_θJC = 2.2 °C/W ensures efficient heat transfer to PCB copper planes or heatsinks.

FAQ

What is the maximum continuous drain current at T_C = +100°C?

The DMNH6035SPDW supports 21 A continuous drain current at case temperature +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by R_θJC = 2.2 °C/W and package power dissipation capability, not silicon degradation.

Does this MOSFET require gate resistors for safe operation?

Yes-external gate resistors (typically 5–22 Ω) are recommended to control dV/dt and prevent parasitic oscillation during switching. The device's Q_g = 16 nC and low C_iss make it sensitive to ringing without proper gate drive impedance matching.

Is the body diode suitable for synchronous rectification?

Yes-the body diode has t_RR = 28 ns and Q_RR = 28 nC at I_F = 20 A, making it viable for synchronous rectification in medium-frequency buck converters (<500 kHz), provided gate timing avoids shoot-through and layout minimizes loop inductance.

How does the PowerDI5060-8 package improve thermal performance over SO-8?

The PowerDI5060-8 exposes both drain terminals as large copper pads directly soldered to PCB thermal planes, achieving R_θJC = 2.2 °C/W-nearly 3× better than typical SO-8 packages (~6–7 °C/W)-enabling higher power density without heatsinks in compact designs.
