Diodes Incorporated ZXMS6004DGQ-13

Overview

ZXMS6004DGQ-13 from Diodes Incorporated is a 60V N-channel self-protected IntelliFET® MOSFET in SOT223 package, functioning as a logic-level low-side power switch with integrated overtemperature, overcurrent, overvoltage (active clamp), and ESD protection. It delivers 1.3A nominal load current at 5V input, exhibits 400–600mΩ R_DS(ON), and supports 490mJ unclamped inductive energy - ideal for driving lamps, motors, and relay-replacement loads in 12V/24V DC industrial and automotive systems.

For engineers reviewing the ZXMS6004DGQ-13 datasheet, ZXMS6004DGQ-13 pinout, ZXMS6004DGQ-13 application, or ZXMS6004DGQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, thermal shutdown with auto-restart, active overvoltage clamping at 60–70V, and linear-mode capability enabling robust inrush current handling without external protection circuitry.

Technical Context

The ZXMS6004DGQ-13 integrates protection logic that deactivates current limiting at low V_DS to minimize on-state dissipation, allowing continuous operation up to thermal limits of the PCB/package rather than protection thresholds. Its input threshold (0.7–1.5V) ensures reliable turn-on from 3.3V/5V microcontrollers, while short-circuit protection triggers at V_DS(SC) = 36V with auto-restart recovery.

Overvoltage protection uses an active clamp architecture to limit drain-source voltage to 60–70V during transients, and thermal shutdown activates at +150°C to +175°C junction temperature with +10°C hysteresis. The device sustains 2.5A pulsed drain current at 5V input and maintains <0.5μA off-state leakage at 36V V_DS.

FAQ

What is the maximum continuous current the ZXMS6004DGQ-13 can deliver in a typical PCB layout?

The ZXMS6004DGQ-13 delivers 1.3A continuous drain current at 5V input and +25°C ambient when mounted on FR-4 with a 1-inch square copper pour (R_θJA = 74°C/W). At elevated temperatures or reduced copper area, current must be derated using the 13.5mW/°C linear factor to maintain T_J ≤ +150°C.

Does the device require an external flyback diode when switching inductive loads?

No external flyback diode is required. The ZXMS6004DGQ-13 incorporates active overvoltage clamping that limits V_DS to 60–70V during inductive turn-off transients, absorbing up to 490mJ of energy - sufficient for most 12V/24V solenoid and small-motor applications.

How does the thermal shutdown behave during sustained overload conditions?

Under sustained overload, the device trips thermal shutdown at +150°C to +175°C junction temperature and enters auto-restart mode with +10°C hysteresis. It cycles on/off until the fault is removed, preventing permanent damage while maintaining visibility of the fault condition via load current interruption.

Is the ZXMS6004DGQ-13 compatible with 3.3V microcontroller GPIO without level shifting?

Yes. With a guaranteed input threshold voltage of 0.7–1.5V and full turn-on at 3V, the ZXMS6004DGQ-13 interfaces directly with 3.3V MCU GPIO pins. Input current remains ≤100μA at 3V, eliminating loading concerns and enabling direct connection without buffer stages.
