Diodes Incorporated ZXMS6004DT8QTA

Overview

ZXMS6004DT8QTA from Diodes Incorporated is a dual-channel, logic-level, self-protected N-channel IntelliFET® MOSFET with 60V V_DS, 400–600 mΩ R_DS(on) at 5V gate drive, 1.2A nominal load current, and integrated active-clamp overvoltage protection. It serves as a rugged, μC-compatible low-side power switch for automotive and industrial DC loads including lamps, motors, and relays.

For engineers reviewing the ZXMS6004DT8QTA datasheet, ZXMS6004DT8QTA pinout, ZXMS6004DT8QTA application, or ZXMS6004DT8QTA equivalent, key selection criteria include its AEC-Q101 qualification, dual independent channel isolation, linear-mode current limiting, thermal shutdown with auto-restart, and SM-8 package thermal performance under 12V/24V DC switching conditions.

Technical Context

The ZXMS6004DT8QTA integrates two fully independent IntelliFET channels in a single SM-8 package, each featuring active-clamp overvoltage protection (V_DS(AZ) = 60–70 V), programmable current limiting (1.7 A typ. at 5 V input), and thermal shutdown triggered at 150–175 °C with 10 °C hysteresis. Its logic-level input accepts 3.3 V or 5 V microcontroller signals without external level-shifting.

Each channel operates in enhancement mode with integrated ESD protection (4 kV HBM), short-circuit protection with auto-restart, and linear-mode capability enabling safe operation at low V_DS where current limiting deactivates to minimize conduction loss-thermal limits, not protection circuitry, govern maximum DC current.

FAQ

What is the maximum continuous current per channel at 85°C ambient?

At T_A = 85 °C, the ZXMS6004DT8QTA supports 0.9 A per channel with one active die (R_θJA = 108 °C/W) and 0.7 A with both channels active (R_θJA = 75 °C/W), assuming a 25 mm × 25 mm FR4 PCB with 1 oz copper. Derating follows 9.28 mW/°C (single) or 13.3 mW/°C (dual) linear factors.

Can ZXMS6004DT8QTA drive inductive loads without external flyback diodes?

Yes-the device features integrated active-clamp overvoltage protection with V_DS(AZ) = 60–70 V and 210 mJ unclamped inductive energy rating. This eliminates the need for external flyback diodes in most 12 V/24 V relay or solenoid applications, though layout-dependent parasitic inductance may still require local RC snubbing in high-dI/dt cases.

How does the linear-mode current limiting behave during PWM operation?

Current limiting activates only in saturation (high V_DS) and deactivates below ~1 V V_DS, allowing full PWM duty-cycle operation without interference. During PWM, the device remains in ohmic region at low V_DS, so conduction loss is minimized and thermal rise is governed solely by average power-not peak current.

Is the SM-8 package lead-free and RoHS-compliant?

Yes-ZXMS6004DT8QTA features matte tin-plated terminals, halogen- and antimony-free "Green" molding compound (Br+Cl < 1500 ppm, Sb < 1000 ppm), and complies with EU RoHS Directive 2011/65/EU. Moisture sensitivity is rated Level 1 per J-STD-020, supporting standard reflow profiles without baking.
