Product details
Overview
ZXMN2A03E6TA from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in SOT26 package, featuring 55 mΩ RDS(ON) at VGS = 4.5V, 4.6A continuous drain current at TA = +25°C, and fast switching with 4.7 ns turn-on delay. It serves as a high-efficiency synchronous rectifier or load switch in compact DC-DC converters.
For engineers reviewing the ZXMN2A03E6TA datasheet, ZXMN2A03E6TA pinout, ZXMN2A03E6TA application, or ZXMN2A03E6TA equivalent, key selection criteria include low-voltage gate drive compatibility (2.5V–4.5V), thermal resistance (70 °C/W on FR-4), body diode recovery (12 ns tRR), and lead-free SOT26 footprint suitability for space-constrained power stages.
Technical Context
This MOSFET employs planar trench-enhanced silicon technology to achieve low RDS(ON) while maintaining controlled gate charge (Qg = 8.2 nC) and low output capacitance (Coss = 168 pF). Its 0.7 V gate threshold enables reliable turn-on with 2.5 V logic-level drivers.
The integrated body diode exhibits 0.85–0.95 V forward voltage at 4.1 A and 12 ns reverse recovery time-critical for minimizing shoot-through loss and ringing in buck converter freewheeling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Maximum blocking voltage for 3.3 V/5 V input rail applications |
| RDS(ON) | 55 mΩ @ VGS = 4.5V - Enables <120 mW conduction loss at 4.6 A in 12 mm² PCB area |
| ID (continuous) | 4.6 A @ TA = +25°C - Supports >3 W output in thermally unenhanced SOT26 layout |
| Qg | 8.2 nC - Allows efficient 1–2 MHz switching with <1 W gate driver power at 5 V |
| tRR | 12 ns - Reduces cross-conduction risk and EMI in synchronous buck topologies |
| RθJA | 70 °C/W - Requires minimal copper pour for operation up to +70°C ambient |
Pinout & Package
SOT26 (6-pin SC-74) surface-mount package with exposed drain pad for thermal relief; dimensions per AP02002: 3.0 × 2.8 × 1.1 mm, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal; accepts 2.5–12 V logic-level drive; 90 pF Crss minimizes Miller-induced oscillation |
| 2 (S) | Source | Power return node; tied to ground or low-side reference; low-inductance connection critical for dI/dt stability |
| 3 (D) | Drain | Main power path output; connected to inductor node in buck converters; exposed pad electrically tied to Drain |
| 4 (S) | Source | Second source terminal-parallel connection with Pin 2 reduces source inductance in high-frequency switching |
| 5 (D) | Drain | Second drain terminal-parallel connection with Pin 3 improves current sharing and thermal spreading |
| 6 (G) | Gate | Redundant gate connection; used for Kelvin gate sensing or noise immunity in high-dI/dt layouts |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(ON) at 2.5 V drive | 100 mΩ - Enables full-load operation from 2.5 V microcontroller GPIO without level-shifting |
| Ultra-low Qgd/Qg ratio | 2.0/8.2 = 0.24 - Improves hard-switching efficiency and reduces gate drive losses |
| Fast body diode recovery | tRR = 12 ns - Limits reverse recovery energy (QRR = 4.9 nC) in synchronous rectification |
| Green molding compound | UL 94V-0, halogen/antimony-free - Meets IPC-1752A environmental compliance for consumer and industrial end equipment |
Applications
| USB Power Delivery Sink | LED Backlight Driver |
|---|---|
Use Scenario: Low-voltage, high-current path control for USB-C PD 3.0 sink circuits delivering up to 20 V/3 A. IC Role / Device Role / Timing Role: Load switch managing VBUS connection between connector and buck controller; operates in linear mode during inrush and saturated switch mode during steady state. Use Value: 55 mΩ RDS(ON) limits voltage drop to <170 mV at 3 A, preserving PD negotiation margin and reducing thermal stress on connector PCB traces. |
Use Scenario: PWM-controlled current sink for white LED strings in thin-profile LCD displays (e.g., tablets, monitors). IC Role / Device Role / Timing Role: High-side current regulator modulating LED current via constant-on-time PWM at 10–50 kHz. Use Value: 8.2 nC total gate charge allows clean 50 kHz square-wave switching with <100 ns rise/fall times, eliminating visible PWM flicker. |
| Industrial Sensor Node PMIC | Portable Audio DC-DC Converter |
Use Scenario: Input protection and sequencing switch in battery-powered IoT sensor nodes with dual-rail (3.3 V/1.8 V) power management ICs. IC Role / Device Role / Timing Role: Reverse-polarity and overvoltage clamp using body diode and VDSS rating; controlled turn-on for inrush limiting. Use Value: 0.7 V VGS(TH) ensures predictable activation from 1.8 V LDO enable signals, preventing brown-out during cold start. |
Use Scenario: Synchronous rectifier in 3.7 V Li-ion to 1.2 V core supply buck converter for Bluetooth audio SoCs. IC Role / Device Role / Timing Role: Low-side synchronous rectifier replacing Schottky diode to improve light-load efficiency. Use Value: 12 ns tRR and 0.85 V VSD reduce freewheeling loss by >35% vs. 0.35 V Schottky at 500 mA, extending playback time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2020LSD-13 | RDS(ON) = 40 mΩ @ 4.5 V but higher Qg = 11.5 nC; SOT23-6 package with same pinout | Better conduction loss but slower switching; less suitable for >1 MHz designs | Prefer when thermal headroom is limited and switching frequency ≤500 kHz |
| AO3400 | RDS(ON) = 44 mΩ @ 4.5 V; higher Ciss = 1050 pF; SOT23-6, non-Green material | Lower RDS(ON) but higher EMI risk due to larger input capacitance and no halogen-free certification | Acceptable for cost-sensitive consumer designs where RoHS/Green compliance is not mandated |
Compared with DMN2020LSD-13 and AO3400, ZXMN2A03E6TA offers optimal balance of low gate charge (8.2 nC), certified Green materials, and 12 ns body diode recovery-making it preferred for high-frequency, environmentally regulated, and EMI-sensitive portable power stages.

FAQ
What is the maximum safe operating junction temperature for ZXMN2A03E6TA?
The device supports continuous operation up to +150°C junction temperature. With RθJA = 70 °C/W on standard FR-4, sustained 4.6 A drain current requires ambient ≤ +70°C or additional copper pour. Derating begins at TA > +25°C per 13.6 mW/°C linear factor.
Can ZXMN2A03E6TA be driven directly from a 1.8 V GPIO?
No. While VGS(TH) is as low as 0.7 V, the RDS(ON) specification of 100 mΩ is guaranteed only at VGS = 2.5 V, and full 4.6 A current capability requires ≥4.5 V. Driving from 1.8 V yields high on-resistance (>500 mΩ) and excessive self-heating.
Is the SOT26 package lead-free and RoHS-compliant?
Yes. ZXMN2A03E6TA uses tin-finished copper leadframe and halogen/antimony-free green molding compound, fully compliant with EU RoHS Directive 2011/65/EU and meeting UL 94V-0 flammability rating. Moisture sensitivity level is rated at Level 1 per J-STD-020.
How does the dual-source/dual-drain configuration improve performance?
The SOT26's parallel Pin 2/Pin 4 (source) and Pin 3/Pin 5 (drain) reduce effective package inductance by ~35% versus single-terminal SOT23-6. This lowers voltage overshoot during turn-off and improves stability in high-dI/dt buck converter applications above 500 kHz.
