Diodes Incorporated ZXMS6005N8Q-13

Overview

ZXMS6005N8Q-13 from Diodes Incorporated is a 60V N-channel self-protected low-side IntelliFET MOSFET with logic-level input, integrated overtemperature/overcurrent/overvoltage (active clamp) protection, 200mΩ R_DS(ON), 2.0A nominal load current at 5V, and SO-8 package-designed for rugged μC-driven switching of lamps, motors, and inductive loads in 12V/24V DC industrial and automotive systems.

For engineers reviewing the ZXMS6005N8Q-13 datasheet, ZXMS6005N8Q-13 pinout, ZXMS6005N8Q-13 application, or ZXMS6005N8Q-13 equivalent, key selection criteria include clamping energy (120mJ), thermal shutdown hysteresis (+10°C), active overvoltage clamp voltage (60–70V), linear-mode current-limiting behavior, and AEC-Q101 qualification for harsh-environment reliability.

Technical Context

The ZXMS6005N8Q-13 implements an integrated protection architecture combining active V_DS clamping (trip at 24V short-circuit, clamp to 60–70V), thermal shutdown with +150°C trip and +10°C hysteresis, and current limiting that deactivates in saturation to preserve low on-state loss. Its logic-level gate accepts 3.3V/5V drive without external level-shifting.

It operates as a protected low-side switch with body diode conduction capability (2.5A continuous, 10A pulsed), supports linear-mode operation below V_DS = 2V where current limiting disengages, and delivers 5A/6A pulsed drain current at 3.3V/5V input respectively-enabling robust in-rush handling for capacitive and inductive loads.

FAQ

What is the maximum continuous current the ZXMS6005N8Q-13 can deliver in a typical PCB layout?

The ZXMS6005N8Q-13 delivers 2.0A continuous drain current at T_A = +25°C with 2oz copper FR-4 and minimum recommended pad layout. This limit is set by thermal dissipation (R_θJA = 98°C/W), not protection circuitry-so actual current depends on board copper area, airflow, and ambient temperature.

Does the device support linear-mode operation, and how does current limiting behave in that region?

Yes-the ZXMS6005N8Q-13 supports linear-mode operation. Its current-limiting circuitry deactivates below V_DS ≈ 2V, allowing unrestricted conduction in saturation. This preserves low on-state loss while retaining full overtemperature, overvoltage, and short-circuit protection at higher V_DS.

How does the active overvoltage clamp function, and what voltage does it trigger at?

The active clamp activates during overvoltage faults (e.g., inductive kickback), limiting V_DS to 60–70V (typical 65V). It triggers when V_DS exceeds 24V in short-circuit conditions and clamps continuously thereafter-eliminating need for external TVS diodes in 24V systems.

Is the ZXMS6005N8Q-13 suitable for automotive under-hood applications, and what qualifications does it hold?

Yes-the ZXMS6005N8Q-13 is AEC-Q101 qualified and PPAP capable. It operates from −40°C to +125°C ambient, withstands automotive temperature cycling and humidity testing, and meets stringent ESD (4kV HBM) and avalanche (120mJ) requirements for engine bay and chassis-mounted modules.
