Product details
Overview
ZXMN4A06GQTA from Diodes Incorporated is a 40V N-channel enhancement-mode MOSFET in SOT223 package, rated for 7A continuous drain current at 25°C, with RDS(ON) = 0.05Ω @ VGS = 10V and VGS(th) = 1–2V. It delivers low gate charge (Qg = 19nC), fast switching (tr = 2.8ns), and AEC-Q101 qualification for automotive-grade reliability in power-switching roles.
For engineers reviewing the ZXMN4A06GQTA datasheet, ZXMN4A06GQTA pinout, ZXMN4A06GQTA application, or ZXMN4A06GQTA equivalent, key selection criteria include its 0.05Ω on-resistance at 10V drive, 22A pulsed drain capability, SOT223 thermal performance (RθJA = 62.5°C/W), and suitability for DC-DC converter high-side switching where low conduction loss and fast turn-off are critical.
Technical Context
This MOSFET employs planar trench-enhanced silicon technology to achieve simultaneous low RDS(ON) and controlled gate charge. Its 1–2V threshold enables direct interface with 3.3V/5V logic without level-shifting, while body diode recovery (trr = 14.5ns, Qrr = 7.8nC) supports synchronous rectification in buck converters.
The device operates across –55°C to +150°C junction range and features robust gate oxide integrity (±20V VGS rating). Its SOT223 package provides 2W power dissipation at 25°C ambient with linear derating to 31mW/°C above 70°C, supporting thermally constrained PCB layouts in motor drivers and solenoid controls.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage before avalanche; suitable for 24V system rails with margin. |
| RDS(ON) | 0.05Ω @ VGS = 10V - Enables <0.25W conduction loss at 7A, reducing thermal load in compact DC-DC stages. |
| ID (continuous) | 7A @ TA = 25°C - Supports high-current loads like automotive window lifters or industrial valve actuators. |
| Qg | 19nC - Low gate drive energy reduces driver IC loading and improves efficiency in 500kHz+ switching applications. |
| tr/tf | 2.8ns / 7.7ns - Fast edge rates minimize switching transition losses in high-frequency SMPS designs. |
| VGS(th) | 1–2V - Ensures full enhancement with standard microcontroller GPIOs, eliminating need for dedicated gate drivers in low-speed control. |
| TJ range | –55°C to +150°C - Validated operation across automotive under-hood and industrial ambient extremes. |
Pinout & Package
Package: SOT223 - Surface-mount plastic package with exposed drain pad for enhanced thermal conduction; 6.5mm × 3.5mm footprint, 1.6mm height, 0.112g mass; UL 94V-0 rated, matte tin annealed terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (D) | Main current path output terminal | Internally connected to exposed metal tab; must be soldered to large copper pour for thermal management and EMI shielding. |
| Source (S) | Reference node for gate control and current return | Provides low-impedance ground reference; ties to power ground plane to minimize switching noise coupling. |
| Gate (G) | Control input for channel modulation | High-impedance MOS gate requiring <100nA leakage; sensitive to ESD-requires series resistor (≥10Ω) near driver output. |
| Tab (Drain) | Thermal and electrical extension of Drain | Electrically identical to Drain pin; mandatory thermal connection to PCB copper for safe 2W operation at ambient. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 4.5V drive | 0.075Ω - Enables efficient operation directly from 5V logic supplies without boost circuitry. |
| Fast body diode recovery | trr = 14.5ns, Qrr = 7.8nC - Reduces reverse-recovery losses in synchronous buck topologies operating >200kHz. |
| AEC-Q101 qualification | Validated for automotive change control, PPAP, and IATF 16949 manufacturing - meets stress-test requirements for engine control modules. |
| Green construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); RoHS 3 compliant - satisfies EU ELV and OEM environmental mandates. |
| Low gate threshold variation | VGS(th) shift <±0.3V over –55°C to +150°C - ensures stable turn-on timing across temperature in battery-powered motor controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | RDS(ON) = 0.025Ω @ 10V but only 30V VDSS; SO-8 package with higher RθJA (70°C/W). | Better conduction loss at lower voltage rails; unsuitable for 40V transients or 36V battery systems. | Select when 30V max system voltage and PCB space allow SO-8; avoid if transient overvoltage >36V is possible. |
| IPB120N04S4-02 | 40V VDSS, RDS(ON) = 0.0012Ω @ 10V, but TO-263 package; Qg = 42nC - double ZXMN4A06GQTA's gate charge. | Higher current capacity (120A) and lower loss, but requires larger layout and more driver strength. | Choose for high-power (>20A) motor drives where SOT223 thermal limits are exceeded; not cost-effective for ≤7A applications. |
Compared with DMN3025LSD-13 and IPB120N04S4-02, ZXMN4A06GQTA uniquely balances 40V robustness, SOT223 compactness, and 19nC gate drive efficiency-making it optimal for space-constrained 7A automotive and industrial switching where thermal budget and driver simplicity are prioritized over ultra-low RDS(ON).

FAQ
Is ZXMN4A06GQTA suitable for use in synchronous rectification?
Yes. Its body diode exhibits trr = 14.5ns and Qrr = 7.8nC at 2.5A, enabling efficient synchronous rectification in buck converters up to 1MHz. The low VSD = 0.8–0.95V further reduces conduction loss compared to external Schottky diodes in 5–12V output stages.
What is the maximum allowable PCB copper area for thermal relief in SOT223 mounting?
For 2W continuous dissipation at 25°C ambient, Diodes recommends ≥25mm × 25mm single-sided 1oz copper coverage beneath the exposed drain tab. Smaller areas increase RθJA beyond the rated 62.5°C/W, requiring derating per Figure 13's transient thermal resistance curves.
Does ZXMN4A06GQTA require a gate resistor in 5V MCU-driven applications?
Yes. A 10–22Ω series gate resistor is recommended to damp ringing caused by trace inductance and MOSFET input capacitance (Ciss = 746pF). This prevents false triggering and reduces EMI, especially when driving inductive loads like solenoids or motors.
How does AEC-Q101 qualification impact ZXMN4A06GQTA's use in non-automotive industrial designs?
AEC-Q101 qualification confirms extended temperature cycling, humidity testing, and mechanical stress validation beyond standard industrial specs. This translates to higher long-term reliability in harsh environments-such as factory-floor motor drives or outdoor telecom power supplies-even when automotive certification isn't mandated.
