Diodes Incorporated ZXMS6004SGTA

Overview

ZXMS6004SGTA from Diodes Incorporated is a 60V N-channel self-protected IntelliFET™ MOSFET in SOT223 package, designed as a rugged low-side power switch with integrated over-current, over-temperature, active over-voltage clamping (V_DS(AZ) = 60–70 V), and ESD protection. It delivers 1.3 A continuous drain current at 5 V logic input, supports μC-compatible 3.3 V/5 V drive, and replaces electromechanical relays in harsh DC switching applications.

For engineers reviewing the ZXMS6004SGTA datasheet, ZXMS6004SGTA pinout, ZXMS6004SGTA application, or ZXMS6004SGTA equivalent, key selection criteria include its 480 mJ unclamped inductive energy rating, 350–600 mΩ R_DS(ON) at 3–5 V gate drive, thermal shutdown with auto-restart, and linear-mode current limiting for lamp/motor in-rush handling.

Technical Context

The ZXMS6004SGTA integrates protection circuitry that activates only under fault conditions-over-current limit deactivates at low V_DS to avoid interference during normal conduction, while active clamp limits V_DS to ≤70 V during inductive turn-off transients. Its logic-level input (V_IN(TH) = 0.7–1.5 V) ensures reliable turn-on from 3.3 V microcontrollers without external level-shifting.

Thermal protection triggers at T_J = +150 °C to +175 °C with +10 °C hysteresis, and recovery occurs automatically after junction cooling. The device sustains 2.5 A pulsed drain current at 5 V input and exhibits 4 kV HBM ESD tolerance-critical for industrial control I/O interfacing where transient immunity is non-negotiable.

FAQ

What is the maximum continuous drain current for ZXMS6004SGTA at 5 V gate drive and 25 °C ambient?

The ZXMS6004SGTA delivers 1.3 A continuous drain current at V_IN = 5 V and T_A = +25 °C when mounted on a 50 mm × 50 mm 2 oz copper PCB. This value drops to 1.0 A on smaller 15 mm × 15 mm 1 oz layouts due to higher thermal resistance (125 °C/W).

Does ZXMS6004SGTA require an external flyback diode when driving inductive loads?

No external flyback diode is required. The device incorporates active over-voltage clamping that limits V_DS to 60–70 V during inductive turn-off, absorbing up to 480 mJ of unclamped inductive energy-sufficient for typical 12 V/24 V solenoids and small DC motors.

Can ZXMS6004SGTA operate reliably with a 3.3 V microcontroller GPIO without level shifting?

Yes. With a guaranteed input threshold voltage (V_IN(TH)) of 0.7–1.5 V and input current ≤100 μA at 3 V, the ZXMS6004SGTA fully turns on using standard 3.3 V logic outputs-no level shifter or gate driver is needed for direct MCU interface.

How does the thermal shutdown and auto-restart function behave under sustained overload?

When junction temperature exceeds +150–+175 °C, the device shuts off and remains off until T_J falls by ≥10 °C. During this cooldown period, the gate is held low and load is disconnected. Once recovered, normal operation resumes automatically-no external reset signal is required.
