Product details
Overview
ZXMN3A03E6TC from Diodes Incorporated is a 30V N-channel enhancement-mode Trench MOSFET in SOT26 package, delivering 4.6A continuous drain current at 25°C, 0.050Ω RDS(ON) @ VGS = 10V, and fast switching (tr = 6.4ns, tf = 11.2ns). It serves as a low-voltage power switch in DC-DC converters and motor control circuits.
For engineers reviewing the ZXMN3A03E6TC datasheet, ZXMN3A03E6TC pinout, ZXMN3A03E6TC application, or ZXMN3A03E6TC equivalent, key selection criteria include its low gate threshold (1V), low gate charge (12.6nC @ 10V), body diode forward voltage (0.85–0.95V), thermal resistance (73°C/W), and SOT26 surface-mount compatibility with high-density PCB layouts.
Technical Context
This MOSFET employs Diodes Incorporated's proprietary Trench process to achieve simultaneous low on-resistance and fast switching-enabled by optimized cell pitch and reduced gate-drain capacitance (Crss = 58.5pF). Its 1V gate threshold supports direct logic-level drive from 3.3V microcontrollers.
The device integrates a robust body diode with 14.1nC reverse recovery charge and 18.8ns trr, enabling efficient synchronous rectification and bidirectional current handling in buck converters and H-bridge motor drivers without external freewheeling diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - maximum blocking voltage for 5V/12V rail applications |
| RDS(ON) | 0.050Ω @ VGS = 10V - enables <120mW conduction loss at 4.6A |
| ID (continuous) | 4.6A @ TA = 25°C - suitable for compact 5–12V power stages up to ~15W |
| Qg | 12.6nC @ VGS = 10V - reduces gate driver power and switching transition time |
| tr/tf | 6.4ns / 11.2ns - supports >1MHz PWM operation with minimal overlap loss |
| VGS(th) | 1V min - ensures turn-on with 3.3V GPIO without level-shifting |
| Ciss | 600pF - limits Miller-induced shoot-through risk in half-bridge configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3025LSD-13 | RDS(ON) = 0.025Ω @ 10V (lower), but SOT23-6 package has higher θJA (100°C/W) | Better conduction loss, but limited to ≤3A continuous due to thermal constraints | Select when peak efficiency at <3A matters more than thermal headroom |
| SI2302DS-T1-GE3 | VGS(th) = 0.6–1.2V (wider spread), RDS(ON) = 0.075Ω @ 4.5V (higher) | Looser threshold tolerance increases risk of partial turn-on in noise-prone environments | Prefer only if cost sensitivity outweighs gate drive margin and RDS(ON) consistency |
Compared with DMN3025LSD-13 and SI2302DS-T1-GE3, ZXMN3A03E6TC delivers balanced performance: tighter VGS(th) distribution, lower Ciss, and superior thermal derating (13.6mW/°C) make it optimal for sustained 4–5A operation in space-constrained 12V systems.

FAQ
What is the maximum continuous drain current for ZXMN3A03E6TC at 70°C ambient?
The maximum continuous drain current is 3.7A at TA = +70°C under the test condition specified in Note 6 of the datasheet (surface mount on FR-4 PCB, t ≤ 10 seconds). This reflects thermal derating from the 4.6A rating at 25°C, based on a linear derating factor of 13.6 mW/°C and 1.7W power dissipation limit.
Does ZXMN3A03E6TC have an integrated body diode, and what are its key parameters?
Yes, ZXMN3A03E6TC includes an intrinsic body diode with forward voltage VSD = 0.85–0.95V at IS = 3.2A and TJ = 25°C. Its reverse recovery characteristics are trr = 18.8ns and Qrr = 14.1nC under IF = 3.5A, di/dt = 100A/μs conditions-enabling use in synchronous rectification without external diodes.
Can ZXMN3A03E6TC be driven directly by a 3.3V microcontroller GPIO?
Yes. With a minimum gate threshold voltage of 1V and typical RDS(ON) = 0.065Ω at VGS = 4.5V, the device achieves full enhancement using standard 3.3V logic outputs. Gate charge is only 12.6nC at 10V, so even at 3.3V drive, turn-on delay remains sub-10ns with appropriate gate resistor selection.
What is the moisture sensitivity level (MSL) and reflow profile compliance for ZXMN3A03E6TC?
ZXMN3A03E6TC has Moisture Sensitivity Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ≤30°C/60% RH without dry-pack requirements. It is compatible with standard Pb-free reflow profiles (peak temperature ≤260°C, 20–40 sec above 217°C), per its matte tin annealed leadframe and green molding compound.
