Diodes Incorporated DMNH6008SCT

Overview

DMNH6008SCT from Diodes Incorporated is an N-channel enhancement-mode power MOSFET in TO220AB package, rated 60V V_DSS, 8.0 mΩ R_DS(ON) @ 10V V_GS, and 130A I_D at T_C = +25°C. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters, motor control, and backlighting systems operating up to +175°C junction temperature.

For engineers reviewing the DMNH6008SCT datasheet, DMNH6008SCT pinout, DMNH6008SCT application, or DMNH6008SCT equivalent, key selection criteria include its 0.7°C/W thermal resistance, 100% unclamped inductive switching rating, AEC-Q101 qualification, and 2.0Ω gate resistance-critical for gate drive design and thermal management in automotive-grade power stages.

Technical Context

This MOSFET employs planar silicon technology optimized for low R_DS(ON) while maintaining robust avalanche capability (E_AS = 190 mJ, I_AS = 62 A). Its gate threshold voltage (2–4 V) enables compatibility with standard 3.3V/5V logic-level drivers when operated above V_GS(TH), and its low C_iss (2596 pF) supports high-frequency switching up to several hundred kHz.

The device integrates a body diode with V_SD = 0.7–1.2 V at 1 A and t_RR = 33 ns, enabling synchronous rectification and freewheeling in buck and half-bridge topologies. Thermal design is anchored by its 0.7°C/W R_θJC, verified under infinite heatsink conditions, and stable R_DS(ON) performance across −55°C to +175°C.

FAQ

What is the maximum continuous drain current for DMNH6008SCT at 100°C case temperature?

The DMNH6008SCT supports 90A continuous drain current at T_C = +100°C, as specified in its Absolute Maximum Ratings table. This derating from 130A at 25°C reflects thermal limitations of the TO220AB package and must be applied in thermal design calculations using R_θJC = 0.7°C/W and ambient/heatsink conditions.

Is DMNH6008SCT pin-compatible with the automotive-grade DMNH6008SCTQ variant?

Yes-DMNH6008SCT and DMNH6008SCTQ share identical TO220AB package, pinout (Drain/Source/Gate), and electrical specifications. The Q suffix denotes AEC-Q101 qualification and enhanced process controls; both parts mount identically and require no PCB redesign.

Does DMNH6008SCT require a gate resistor for stable switching?

A gate resistor is required to control dV/dt and suppress oscillation. With Q_g = 40 nC and typical gate driver output impedance, a 5–10Ω series resistor is recommended to achieve ~10–20 ns rise/fall times while limiting peak gate current to <5A and minimizing EMI.

Can DMNH6008SCT be used in synchronous rectification without external Schottky diodes?

Yes-the integrated body diode has V_SD = 0.7–1.2 V and t_RR = 33 ns, enabling synchronous rectification in buck and flyback converters up to ~300 kHz. For higher frequencies or lower forward drop, external Schottky diodes may still be preferred, but the MOSFET's diode is fully functional for many designs.
