Diodes Incorporated ZXMS6005DT8QTA

Overview

ZXMS6005DT8QTA from Diodes Incorporated is a dual-channel, 60V N-channel self-protected IntelliFET® MOSFET in SM-8 package, featuring 200 mΩ R_DS(on), 1.8 A nominal load current at 5 V input, and integrated active-clamp over-voltage protection. It serves as a rugged, logic-level–driven low-side power switch for inductive loads in automotive and industrial control systems.

For engineers reviewing the ZXMS6005DT8QTA datasheet, ZXMS6005DT8QTA pinout, ZXMS6005DT8QTA application, or ZXMS6005DT8QTA equivalent, key selection criteria include clamping energy (210 mJ), dual-channel thermal shutdown with auto-restart, AEC-Q101 qualification, and compatibility with 3.3 V/5 V microcontroller outputs in harsh environments.

Technical Context

This device integrates two electrically isolated low-side switches with independent protection circuitry per channel-including over-current limiting (2.2–7 A range), active-clamp over-voltage protection (60–70 V clamp), and thermal shutdown at 150–175 °C. Each channel operates with logic-level input (VIH ≥ 3 V, VIL ≤ 0.7 V) and supports linear-mode operation for controlled inrush management.

The SM-8 package enables dual-die thermal coupling while maintaining separate drain-source paths. Safe operating area is defined by junction-to-ambient thermal resistance (75–108 °C/W depending on PCB layout), and short-circuit reliability is characterized per AEC-Q101-006 with 24 V SC voltage rating and 210 mJ unclamped inductive energy handling.

FAQ

What is the maximum continuous drain current per channel at 125°C ambient?

At T_A = +125°C, the continuous drain current is derated to approximately 0.9 A per channel based on the 75 °C/W R_θJA (dual-active-die condition) and 150 °C T_J(max). This assumes a 25 mm × 25 mm 1 oz copper PCB with still air; actual current depends on board thermal design and simultaneous channel loading.

Does ZXMS6005DT8QTA support linear-mode operation for soft-start control?

Yes-the current-limiting protection deactivates at low V_DS to minimize on-state power dissipation, enabling controlled linear-mode operation for inrush current limiting. The device remains protected during saturation transitions, and maximum DC current is determined by thermal capability-not protection circuitry.

Can both channels be driven simultaneously with identical timing?

Yes-IN1 and IN2 are electrically isolated with matched propagation delays (t_d(on) = 6 µs typ., t_d(off) = 34 µs typ.). No cross-talk or timing skew is specified; simultaneous switching is supported for dual-load synchronization such as dual-lamp or dual-solenoid actuation.

Is the SM-8 package thermally enhanced for high-power dissipation?

Yes-the SM-8 package features an exposed drain pad that serves as the primary thermal path to the PCB. With proper copper pour and vias, thermal resistance can reach 26.5 °C/W (junction-to-case), enabling up to 1.67 W continuous dissipation per channel at T_A = +25°C on a 25 mm × 25 mm FR4 board.
