Diodes Incorporated ZXMS6005DT8TA

Overview

ZXMS6005DT8TA from Diodes Incorporated is a dual-channel, self-protected N-channel enhancement-mode IntelliFET® MOSFET in SM-8 package, rated for 60V V_DS, 200 mΩ R_DS(on) at 5V drive, and 1.8A nominal load current. It integrates active over-voltage clamping (24V short-circuit clamp), thermal shutdown with auto-restart, and ESD protection (4 kV HBM), enabling robust low-side switching of inductive loads like lamps and solenoids in automotive and industrial control systems.

For engineers reviewing the ZXMS6005DT8TA datasheet, ZXMS6005DT8TA pinout, ZXMS6005DT8TA application, or ZXMS6005DT8TA equivalent, key selection criteria include logic-level compatibility (3.3V/5V input), dual-channel isolation, clamping energy rating (210 mJ), thermal derating (75 °C/W R_θJA with two active dies), and AEC-Q101 qualification for automotive reliability.

Technical Context

The ZXMS6005DT8TA implements two fully isolated low-side power switches with integrated protection circuitry: active voltage clamping limits V_DS to 24V during short-circuit events, while thermal and over-current protection operate independently per channel with auto-restart recovery. Its linear-mode capability allows controlled current limiting without premature trip under low-V_DS conditions.

Input threshold is specified at 0.7–1.5V (V_IN(th)), supporting direct interface with 3.3V and 5V microcontrollers. The device sustains 6A pulsed drain current at 5V input and delivers 1.8A continuous current at T_A = +25°C with dual-die operation on standard FR4 PCB.

FAQ

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

At T_A = +85°C, the ZXMS6005DT8TA supports 1.1A continuous current per channel with two active dies, based on its 13.3 mW/°C linear derating from 1.67 W at 25°C and thermal resistance of 75 °C/W. This assumes a 25 mm × 25 mm single-sided 1 oz copper FR4 PCB in still air.

Does the device require external flyback diodes for inductive loads?

No external flyback diode is required. The ZXMS6005DT8TA integrates a body diode with 2.5A continuous and 10A pulsed source current capability, and its active 24V V_DS(SC) clamp safely absorbs inductive energy up to 210 mJ per pulse without external components.

How does the auto-restart thermal protection behave during sustained overload?

When junction temperature exceeds 150–175°C, the device shuts down both channels and remains off until temperature drops by ≥10°C hysteresis. It then automatically resumes operation-providing fault resilience without manual reset, though repeated cycling indicates inadequate heatsinking or excessive load duty cycle.

Can IN1 and IN2 be driven from different voltage domains (e.g., 3.3V and 5V simultaneously)?

Yes. IN1 and IN2 are electrically isolated inputs with identical 0–5.5V absolute maximum ratings and 0.7–1.5V threshold range. Driving them from separate 3.3V and 5V logic sources is supported and does not affect channel independence, protection behavior, or timing performance.
