Diodes Incorporated DMNH6022SSD-13

Overview

DMNH6022SSD from Diodes Incorporated is a 60V dual N-channel MOSFET in SO-8 package, rated for continuous drain current up to 22.6A at TC = +25°C, with RDS(ON) of 27mΩ @ VGS = 10V and 30mΩ @ VGS = 6V. It supports operation up to +175°C junction temperature and is AEC-Q101 qualified for automotive engine management and body control electronics.

For engineers reviewing the DMNH6022SSD datasheet, DMNH6022SSD pinout, DMNH6022SSD application, or DMNH6022SSD equivalent, key selection criteria include its dual-channel layout, low gate charge (Qg = 32nC @ 10V), 100% unclamped inductive switching rating, thermal robustness to +175°C, and SO-8 footprint compatibility with high-density DC-DC converter designs.

Technical Context

This dual N-channel MOSFET integrates two independent 60V, 22.6A channels in a single SO-8 package with shared source terminals (S1/S2) and isolated gates (G1/G2). Its design emphasizes low conduction loss via 27mΩ RDS(ON) at 10V drive and low switching loss via 32nC total gate charge and 54pF Crss.

The device features fully independent channel operation, 100% UIS-rated avalanche capability (IAS = 22A, EAS = 24mJ), and thermal performance validated to TJ = +175°C - enabling use in under-hood automotive power stages where ambient temperatures exceed 125°C.

FAQ

What is the maximum continuous drain current for each channel at TC = +100°C?

Each channel supports 16.0A continuous drain current at TC = +100°C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to reduced package thermal resistance at elevated case temperatures and must be verified against actual PCB layout and heatsinking in the target application.

Is the DMNH6022SSD suitable for high-side switching configurations?

Yes - the dual N-channel architecture supports high-side switching when used with a bootstrap or isolated gate driver. Pin 2 (S1) and Pin 6 (S2) are electrically isolated source terminals, enabling independent floating-source operation for each channel in half-bridge or three-phase inverter topologies.

Does the device include integrated body diodes, and what are their forward voltage characteristics?

Each channel includes an intrinsic body diode with typical forward voltage of 0.8V at IS = 1.7A and VGS = 0V. The diode is rated for continuous forward current up to 2A and exhibits reverse recovery time (tRR) of 18.1ns, supporting efficient synchronous rectification and freewheeling in switching regulators.

How does the SO-8 package affect thermal performance compared to DPAK alternatives?

The SO-8 package delivers RθJA = 74°C/W (with 1-inch² copper pad), significantly better than standard SO-8 ratings due to optimized internal thermal path and double-drain pin construction. While DPAK offers lower RθJA (~50°C/W), SO-8 provides superior board-level density and reflow compatibility - critical for compact automotive modules.
