Diodes Incorporated ZXMS6005SGQTA

Overview

ZXMS6005SGQTA 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 over-temperature, over-current, active-clamp over-voltage, and ESD protection. It delivers 2A nominal load current at 5V input, 170–250 mΩ R_DS(ON), and 480 mJ unclamped inductive energy rating-designed for driving lamps, motors, and relay-replacement loads in automotive and industrial 12V DC systems.

For engineers reviewing the ZXMS6005SGQTA datasheet, ZXMS6005SGQTA pinout, ZXMS6005SGQTA application, or ZXMS6005SGQTA equivalent, this page provides verified functional role, thermal derating behavior, clamping voltage (60–70 V), short-circuit auto-restart timing, and AEC-Q101 qualification status-key selection criteria for ruggedized μC-driven switching in harsh environments.

Technical Context

The ZXMS6005SGQTA integrates protection circuitry that deactivates current limiting at low V_DS to minimize on-state power loss, enabling linear-mode operation where thermal design-not protection thresholds-governs maximum DC current. Its active clamp responds to V_DS(SC) = 24 V transients while maintaining safe SOA under inductive kickback.

Logic-level compatibility spans 3.3 V and 5 V microcontrollers, with VIH ≥ 3 V and VIL ≤ 0.7 V. Input current remains ≤200 μA at 5 V, and thermal shutdown triggers at +150 °C with +10 °C hysteresis, ensuring fault recovery without external supervision.

FAQ

What is the maximum continuous drain current for ZXMS6005SGQTA at 5V input and 25°C ambient?

The ZXMS6005SGQTA delivers 2.0 A continuous drain current at 5V input and +25°C ambient temperature when mounted on a 50 mm × 50 mm 2 oz copper PCB. This value assumes optimal thermal layout with the drain tab fully soldered to the copper pour. Derating begins at 12.8 mW/°C above +25°C ambient.

Does ZXMS6005SGQTA support linear-mode (analog) operation?

Yes-the current-limit protection circuitry deactivates at low V_DS (typically <1 V), enabling safe linear-mode operation for analog current regulation. Maximum DC current is then determined solely by thermal limits of the PCB and package, not by internal protection thresholds.

Is ZXMS6005SGQTA qualified for automotive applications?

Yes-it is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. It meets automotive requirements for temperature range (−40 °C to +150 °C junction), ESD immunity (4 kV HBM), and long-term reliability in under-hood and body-control modules.

How does the active clamp overvoltage protection work in ZXMS6005SGQTA?

The device features an active clamp that limits V_DS to 60–70 V during inductive flyback events. When V_DS exceeds the clamp threshold, internal circuitry diverts energy into the silicon substrate, dissipating up to 480 mJ per pulse-preventing destructive breakdown without external TVS diodes.
