Diodes Incorporated ZXMS6005DGTA

Overview

ZXMS6005DGTA from Diodes Incorporated is a 60V N-channel self-protected IntelliFET™ MOSFET in SOT223 package, functioning as a rugged low-side switch with integrated active clamp, thermal shutdown, short-circuit protection, and logic-level (3.3V/5V) input drive. It delivers 2.0A continuous load current at 5V input, 200mΩ R_DS(ON), and 490mJ unclamped inductive energy handling - ideal for driving lamps, solenoids, and small DC motors in industrial control panels exposed to voltage transients and overtemperature faults.

For engineers reviewing the ZXMS6005DGTA datasheet, ZXMS6005DGTA pinout, ZXMS6005DGTA application, or ZXMS6005DGTA equivalent, key selection criteria include its 60V V_DS, auto-restart overcurrent/overtemperature behavior, active V_DS clamping at 60–70V, 1.3W power dissipation on minimal copper, and compatibility with 3.3V microcontroller GPIOs without level-shifting.

Technical Context

The ZXMS6005DGTA integrates protection circuitry directly into the die: an active clamp limits V_DS during inductive turn-off to 60–70V, while thermal shutdown triggers at +150°C with +10°C hysteresis and auto-restarts upon cooling. Its current-limit threshold is VIN-dependent (2.2A at 3V, 3.3A at 5V), enabling safe saturation operation without false triggering during normal conduction.

It operates as a single-ended low-side switch with three terminals (IN, D, S), where the input controls gate via internal driver, drain connects to load high-side, and source ties to ground. The device sustains 5A pulsed drain current at 3.3V input and 6A at 5V input, with ESD robustness of 4kV HBM and 1kV CDM - critical for factory automation I/O modules subject to cable discharge events.

FAQ

What is the maximum safe inductive load energy the ZXMS6005DGTA can handle without external clamping?

The ZXMS6005DGTA is rated for 490mJ of unclamped single-pulse inductive energy at T_J = +25°C, ID = 0.5A, and V_DD = 24V. This value is measured with the internal active clamp engaged and represents worst-case flyback energy absorption before thermal runaway. For repetitive switching, peak energy must be reduced per the SOA curve in Figure 7 of DS32247 Rev. 4-2.

Does the ZXMS6005DGTA require an external pull-down resistor on the IN pin?

No external pull-down is required. The ZXMS6005DGTA features an internal 10MΩ pull-down on the IN pin, ensuring the MOSFET remains off during power-up, MCU reset, or floating GPIO states. This eliminates risk of unintended load activation in systems with undriven control lines.

Can the ZXMS6005DGTA drive a 24V, 2.2A solenoid continuously at +70°C ambient?

At +70°C ambient, derated continuous current is approximately 1.6A (based on R_θJA = 42°C/W and T_J(max) = +150°C). Driving a 2.2A solenoid continuously would exceed safe junction temperature. For this load, use pulsed operation with ≤50% duty cycle or add forced airflow to maintain T_J ≤ +150°C.

How does the auto-restart behavior function during overtemperature fault?

When junction temperature exceeds +150°C, the device shuts down and holds OFF until T_J falls by ≥10°C (hysteresis). It then automatically resumes normal switching without external intervention. This cycle repeats if the thermal fault persists, preventing permanent damage while maintaining functional awareness in intermittently overloaded systems.
