Diodes Incorporated ZXMS6004DGTA

Overview

ZXMS6004DGTA from Diodes Incorporated is a 60V N-channel self-protected IntelliFET™ MOSFET in SOT223 package, designed as a logic-level low-side power switch with integrated over-current, over-temperature, active-clamp over-voltage, and ESD protection. It delivers 1.3A continuous drain current at 5V input, 400–600mΩ R_DS(ON), and 490mJ unclamped inductive energy rating for rugged switching of lamps, motors, and DC loads up to 24V.

For engineers reviewing the ZXMS6004DGTA datasheet, ZXMS6004DGTA pinout, ZXMS6004DGTA application, or ZXMS6004DGTA equivalent, this page provides verified functional context, thermal derating behavior, clamping voltage (60–70V), current-limit thresholds (0.7–2.2A), and μC-compatible 3.3V/5V drive requirements - all critical for automotive-grade load switching and relay replacement designs.

Technical Context

The ZXMS6004DGTA integrates protection circuitry that deactivates current limiting at low V_DS to minimize on-state power loss, enabling linear-mode operation while preserving fault response at high V_DS. Its active clamp limits transient voltage to 60–70V during inductive turn-off, and thermal shutdown triggers at +150°C with +10°C hysteresis.

It operates with VIH ≥3V and VIL ≤0.7V, supports 0–5.5V input range, and sustains 2.5A pulsed drain current at 5V drive. Protection functions - including short-circuit auto-restart, ESD (4kV HBM), and dV/dt immunity - are fully embedded without external components.

FAQ

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

At T_A = 85°C on a 50mm×50mm 2oz copper board, the ZXMS6004DGTA supports approximately 0.9A continuous drain current. This is derived from its 24W P_D at 25°C and 42°C/W thermal resistance: (150°C − 85°C) × 24mW/°C = 1560mW, yielding I_D ≈ √(1.56W / 0.5Ω) ≈ 1.76A - but derated to 0.9A per datasheet note for sustained reliability under worst-case R_DS(ON) and layout variation.

Does the device require an external flyback diode?

No external flyback diode is required. The ZXMS6004DGTA incorporates an active-clamp circuit that limits V_DS to 60–70V during inductive turn-off, absorbing energy internally. Its body diode is rated for 1A continuous and 5A pulsed source current, sufficient for typical flyback recovery in low-energy loads like lamps and small solenoids.

Can ZXMS6004DGTA be used in linear (analog) mode for current regulation?

Yes - its current-limit circuitry deactivates below ~1V V_DS, allowing stable linear-mode operation without false triggering. This enables use in analog dimming or soft-start applications where precise current control is needed, provided board-level thermal design supports power dissipation (e.g., 50mm×50mm 2oz copper for >1W).

Is the SOT223 (DN) package lead-free and RoHS compliant?

Yes - the ZXMS6004DGTA uses matte tin finish terminals and green molding compound compliant with EU RoHS 2015/863/EU (RoHS 3), containing <900ppm bromine, <900ppm chlorine, and <1000ppm antimony. It meets J-STD-020 moisture sensitivity Level 1 and UL 94V-0 flammability rating.
