Diodes Incorporated ZXMS6006DT8QTA

Overview

ZXMS6006DT8QTA from Diodes Incorporated is a dual-channel, logic-level, self-protected N-channel IntelliFET MOSFET in SM-8 package, rated for 60V V_DS, 100mΩ R_DS(on) at 5V drive, and 2.8A continuous drain current. It integrates active overvoltage clamping (65V typical), thermal shutdown with auto-restart, short-circuit protection, and ESD-hardened input-designed for driving lamps, solenoids, relays, and small motors in automotive and industrial control systems.

For engineers reviewing the ZXMS6006DT8QTA datasheet, ZXMS6006DT8QTA pinout, ZXMS6006DT8QTA application, or ZXMS6006DT8QTA equivalent, key selection criteria include its dual low-side switching capability, AEC-Q101 qualification, 3.3V/5V logic compatibility, integrated fault protections, and SM-8 thermal performance under pulsed load conditions.

Technical Context

The ZXMS6006DT8QTA implements two independent IntelliFET channels sharing a common ground, each featuring active clamp circuitry that limits V_DS to ≤70V during inductive turn-off transients and delivers 210mJ unclamped inductive energy handling. Its protection architecture combines real-time current limiting (6–13A depending on VIN), junction temperature monitoring (trip at +150°C ±25°C), and input voltage clamping (−0.5V to +6V).

Each channel operates as a high-side referenced load switch with logic-level gate drive: VIH ≥3V ensures full enhancement, while VIL ≤0.7V guarantees reliable off-state. The device sustains 2.8A continuous current per channel at T_A = +25°C on a 25mm × 25mm 1oz FR4 board, with R_θJA = 75°C/W when both dies are active.

FAQ

What is the maximum pulsed drain current rating for ZXMS6006DT8QTA?

The ZXMS6006DT8QTA supports 13A pulsed drain current per channel at VIN = 5V, tested under 300μs pulse width with 2% duty cycle on a 25mm × 25mm FR4 board. This rating is limited by junction temperature rise and remains valid only when thermal derating curves are observed-exceeding this value risks triggering overtemperature shutdown.

Does ZXMS6006DT8QTA require an external flyback diode when driving inductive loads?

No external flyback diode is required. The device incorporates active overvoltage clamping that limits V_DS to ≤70V during inductive turn-off, and its 210mJ E_AS rating handles typical 24V relay and solenoid energy without external components-verified per JEDEC JESD24-11 testing.

How does the thermal shutdown and auto-restart function operate?

When junction temperature exceeds +150°C, the device disables both channels and enters thermal shutdown. After cooling below hysteresis threshold (+140°C), it automatically resumes normal operation without external reset. This behavior is confirmed in DS37137 Rev. 3 Section 4.2 and validated across −40°C to +125°C ambient range.

Is ZXMS6006DT8QTA pin-compatible with earlier ZXMS6004 or ZXMS6008 variants?

No-ZXMS6006DT8QTA uses SM-8 package with 8 pins and dual independent source terminals (S1/S2), whereas ZXMS6004 is in SOT23-6 and ZXMS6008 is in SO-8 with different pin mapping. Electrical characteristics also differ significantly in R_DS(on), current rating, and protection thresholds-direct substitution is not supported.
