Diodes Incorporated ZXMS6004DGQTA

Overview

ZXMS6004DGQ from Diodes Incorporated is a 60V N-channel self-protected low-side IntelliFET® MOSFET with logic-level input, integrating overtemperature, overcurrent, overvoltage (active clamp), and ESD protection. It delivers 1.3A nominal load current at 5V input, features 400–600mΩ R_DS(ON), and supports linear-mode operation for inrush-tolerant switching of lamps and motors in 12V/24V DC systems.

For engineers reviewing the ZXMS6004DGQ datasheet, ZXMS6004DGQ pinout, ZXMS6004DGQ application, or ZXMS6004DGQ equivalent, key selection criteria include its AEC-Q101 qualification, 490mJ unclamped inductive energy rating, thermal shutdown with auto-restart, and compatibility with 3.3V/5V microcontrollers in automotive and industrial harsh-environment designs.

Technical Context

The ZXMS6004DGQ implements integrated protection circuitry that activates only under fault conditions-overcurrent limiting deactivates at low V_DS to preserve on-state efficiency, while active overvoltage clamping holds V_DS ≤70V during inductive flyback. Its logic-level gate accepts 0.7–1.5V threshold inputs and draws ≤200μA at 5V.

Thermal protection triggers at +150°C to +175°C junction temperature with +10°C hysteresis, and short-circuit response limits pulsed drain current to 2.5A at 5V input. The device operates across –40°C to +125°C ambient and sustains 1A continuous source current via its internal body diode.

FAQ

What is the maximum continuous drain current for ZXMS6004DGQ at 70°C ambient?

At T_A = 70°C, continuous drain current is derated from 1.3A (at 25°C) using the 13.5mW/°C linear derating factor from the 1.67W P_D rating on a 1-inch² copper pad. This yields approximately 0.85A, confirmed by the thermal resistance R_θJA = 74°C/W and T_J(max) = 150°C limit.

Does ZXMS6004DGQ support PWM dimming of LED loads?

Yes-the device supports PWM switching up to 20kHz with 5μs turn-on delay and 15μs fall time. Its active overvoltage clamp and 490mJ E_AS rating protect against inductive kickback from LED driver inductors, and thermal auto-restart ensures safe operation during extended duty cycles.

Can ZXMS6004DGQ be used in high-side configuration?

No-it is designed exclusively as a low-side switch. The internal protection circuitry, gate drive architecture, and pinout (source-connected pins 1 and 4) require the load to be connected between supply and drain. High-side use would violate absolute maximum ratings and disable protection functions.

Is the SOT223 package lead-free and RoHS compliant?

Yes-ZXMS6004DGQ features matte tin finish terminals and is RoHS 3 compliant (2015/863/EU), halogen- and antimony-free ("Green"), with UL 94V-0 molded plastic housing and J-STD-020 Level 1 moisture sensitivity rating.
