Product details
Overview
ZXMN2A01E6TA from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in SOT26 package, featuring 120 mΩ RDS(ON) at VGS = 4.5 V, 3.1 A continuous drain current at TA = +25°C, and fast switching (tF = 4.62 ns). It serves as a low-voltage power switch in DC-DC converters and load disconnect circuits.
For engineers reviewing the ZXMN2A01E6TA datasheet, ZXMN2A01E6TA pinout, ZXMN2A01E6TA application, or ZXMN2A01E6TA equivalent, key selection criteria include gate threshold voltage (0.7 V min), body diode forward voltage (0.9 V typ), thermal resistance (70 °C/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This MOSFET employs trench-gate technology to achieve low on-resistance and high switching speed simultaneously. Its 0.7 V minimum VGS(TH) enables direct drive from 1.8 V and 3.3 V logic, while the 3.0 nC total gate charge supports efficient PWM operation at frequencies up to several MHz.
The integrated body diode exhibits 23 ns reverse recovery time and 5.65 nC QRR, making it suitable for synchronous rectification and freewheeling in buck converters. Thermal design is supported by two distinct power dissipation ratings: 1.1 W (113 °C/W) for standard PCB layout and 1.7 W (70 °C/W) for short-duration pulse conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 20 V - Maximum blocking voltage for low-voltage power rails (e.g., 12 V, 5 V, 3.3 V systems) |
| RDS(ON) | 120 mΩ @ VGS = 4.5 V - Enables <150 mW conduction loss at 3.1 A, critical for thermally constrained PCBs |
| ID (cont) | 3.1 A @ TA = +25°C - Supports compact point-of-load regulators without external heatsinking |
| VGS(TH) | 0.7 V min - Ensures reliable turn-on with low-voltage microcontrollers and PMIC outputs |
| Qg | 3.0 nC - Reduces gate drive power and allows use of low-current drivers in space-constrained designs |
| tF | 4.62 ns - Limits switching transition losses in high-frequency (>1 MHz) DC-DC topologies |
| RθJA | 70 °C/W - Validated for FR-4 PCBs under pulsed conditions; informs thermal margin for intermittent loads |
Pinout & Package
SOT26 (6-pin) surface-mount package with exposed drain pad for enhanced thermal performance. Molded plastic housing meets UL 94V-0 flammability rating and J-STD-020 Level 1 moisture sensitivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (D) | Drain | Main high-side or low-side current path; internally connected to exposed pad for thermal conduction |
| 2 (G) | Gate | Control input; low 3.0 nC charge enables fast, low-power switching |
| 3 (S) | Source | Reference node for gate drive; tied to power ground or floating return in high-side configurations |
| 4 (D) | Drain | Parallel drain connection; electrically identical to Pin 1 for current sharing and thermal spreading |
| 5 (S) | Source | Second source terminal; reduces bond wire inductance and improves high-frequency stability |
| 6 (D) | Drain | Third drain terminal; increases copper area for heat transfer and current handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2020LSD-13 | RDS(ON) = 100 mΩ @ 4.5 V; SOT23-6 package; higher 3.5 A ID | Better conduction loss but lower thermal mass; less suitable for sustained 3 A loads | Select when peak efficiency at 2 A is prioritized over thermal margin at full rated current |
| SI2302DS-T1-GE3 | RDS(ON) = 150 mΩ @ 4.5 V; no AEC-Q101 qualification; 2.8 A ID | Cost-optimized for consumer electronics; not validated for automotive temperature cycling | Select for non-automotive applications where AEC-Q101 is not required and 30 mΩ higher RDS(ON) is acceptable |
Compared with DMN2020LSD-13 and SI2302DS-T1-GE3, ZXMN2A01E6TA delivers balanced performance: its 120 mΩ RDS(ON) and AEC-Q101 rating make it optimal for automotive and industrial 3 A switching loads where reliability and thermal robustness outweigh marginal conduction loss differences.

FAQ
What is the maximum continuous drain current at 70°C ambient?
The ZXMN2A01E6TA supports 2.5 A continuous drain current at TA = +70°C, as specified in the Absolute Maximum Ratings table (Note 6). This derating reflects thermal limits on a standard FR-4 PCB under steady-state conditions and must be verified against actual board layout and airflow.
Is the body diode suitable for synchronous rectification?
Yes-the body diode has 23 ns reverse recovery time and 5.65 nC QRR, measured at TJ = +25°C with IF = 4 A and di/dt = 100 A/μs. These values enable effective synchronous rectification in buck converters operating below 2 MHz, provided gate timing avoids shoot-through.
Does ZXMN2A01E6TA require a gate resistor for ESD protection?
No dedicated gate resistor is required for ESD protection-the device features integrated gate protection diodes and is rated for ±12 V gate-source voltage. However, a small series gate resistor (e.g., 10 Ω) is recommended to dampen ringing and limit peak gate current during fast switching transitions.
How does the SOT26 package compare thermally to standard SOT23-3?
The SOT26 package provides three drain terminals and dual source connections, increasing copper area and reducing thermal resistance to 70 °C/W (vs. ~200 °C/W for typical SOT23-3). This enables 1.7× higher power dissipation under pulsed conditions and better current sharing in high-frequency switching applications.
