Diodes Incorporated ZXMS6005DGQ-13

Overview

ZXMS6005DGQ-13 from Diodes Incorporated is a 60V N-channel self-protected low-side IntelliFET® MOSFET with logic-level input, designed for rugged switching in harsh environments. It delivers 2.0A continuous load current at 5V drive, features 200mΩ R_DS(ON), integrated active overvoltage clamping (60–70V), and 490mJ unclamped inductive energy rating-ideal for driving solenoids, relays, and DC motors in automotive and industrial control systems.

For engineers reviewing the ZXMS6005DGQ-13 datasheet, ZXMS6005DGQ-13 pinout, ZXMS6005DGQ-13 application, or ZXMS6005DGQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, thermal shutdown with auto-restart, short-circuit protection behavior, and compatibility with 3.3V/5V microcontroller GPIOs without external gate drivers.

Technical Context

The ZXMS6005DGQ-13 integrates protection circuitry directly into the die: overcurrent limiting triggers at 3.3–7A (depending on VIN), overtemperature shutdown activates at +150°C to +175°C with +10°C hysteresis, and active clamp limits V_DS during inductive kickback to 60–70V. Its logic-level input accepts 0.7–1.5V threshold and draws only 60–200μA at 3–5V, enabling direct MCU interfacing.

It operates as a single-chip protected switch: the drain-source path handles up to 2.0A continuously (at T_A = +25°C with enhanced copper layout), while internal sensing monitors junction temperature, current, and voltage simultaneously-triggering fault responses without external components. The device remains functional under sustained 24V V_DS(SC) short-circuit conditions before entering safe auto-restart cycles.

FAQ

What is the maximum ambient temperature at which ZXMS6005DGQ-13 can deliver 2.0A continuously?

The ZXMS6005DGQ-13 sustains 2.0A continuous drain current at T_A = +25°C when mounted on an FR-4 PCB with a 1-inch square copper pour (R_θJA = 74°C/W). At T_A = +85°C, derating reduces usable current to approximately 1.3A based on thermal limits and R_DS(ON) increase. Full 2.0A operation requires active thermal management above +60°C ambient.

Does ZXMS6005DGQ-13 require an external flyback diode when driving inductive loads?

No external flyback diode is required. The device incorporates an active overvoltage clamp that limits V_DS to 60–70V during inductive turn-off, absorbing up to 490mJ of unclamped energy. This internal protection eliminates the need for external diodes in most relay, solenoid, and lamp applications-verified per the DS40464 Rev. 2-2 test conditions.

Can ZXMS6005DGQ-13 be used with 3.3V microcontrollers without a level shifter?

Yes. Its input threshold voltage (V_IN(TH)) ranges from 0.7V to 1.5V, and it draws only 60–100μA at 3V input-well within standard GPIO sink/source capability. The device turns fully on with 3.3V drive, achieving R_DS(ON) ≤ 250mΩ at 1A, making level shifters unnecessary in typical embedded control designs.

How does the auto-restart feature behave during a sustained short-circuit condition?

Under sustained short-circuit, the device enters current-limit mode (ID(LIM) = 3.3–7A depending on VIN), then shuts down thermally after ~10–50ms. It automatically restarts after cooling below hysteresis threshold (~10°C below trip), repeating the cycle. This prevents destructive overheating while maintaining visibility of fault state-no external watchdog or reset circuitry is needed for basic protection.
