Product details

Overview

ZXMN2A01FTC from Diodes Incorporated is a 20V N-channel enhancement-mode MOSFET in SOT23 package, featuring 0.12Ω R_DS(ON) at V_GS = 10V, 2.2A continuous drain current at +25°C, and AEC-Q101 qualification for automotive-grade reliability-used as a low-side power switch in DC-DC converter synchronous rectification stages.

For engineers reviewing the ZXMN2A01FTC datasheet, ZXMN2A01FTC pinout, ZXMN2A01FTC application, or ZXMN2A01FTC equivalent, key selection criteria include its 0.12Ω on-resistance at 10V gate drive, 2.5V threshold voltage enabling 3.3V logic compatibility, fast 2.49ns turn-on delay, and SOT23 thermal resistance of 155°C/W under pulsed conditions.

Technical Context

This MOSFET employs planar trench-enhanced silicon process to achieve low R_DS(ON) while maintaining controlled gate charge (Q_g = 3.0nC) and fast switching (t_r = 5.21ns). Its body diode exhibits V_SD = 0.85V at 3.2A, supporting efficient freewheeling in buck converters.

The device operates with V_GS(th) = 0.7V (min), enabling reliable turn-on from 2.5V microcontroller outputs; gate capacitances (C_iss = 303pF, C_rss = 30pF) support stable PWM control up to 1MHz without excessive driver loading.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	20V - supports input rails up to 18V in industrial and automotive 12V systems
R_DS(ON)	0.12Ω @ V_GS = 10V - delivers ≤53mW conduction loss at 2.2A, critical for thermally constrained SOT23 layouts
I_D (continuous)	2.2A @ T_A = +25°C - enables compact point-of-load regulation without external heatsinking
V_GS(th)	0.7V (min) - ensures full enhancement with 2.5V/3.3V logic-level gate drivers
Q_g	3.0nC - allows efficient 1MHz PWM switching with <10mA average gate current from standard drivers
t_D(on)	2.49ns - minimizes dead-time losses in synchronous buck topologies
R_θJA	155°C/W (pulsed) - defines maximum allowable power dissipation before junction exceeds 150°C on FR-4 PCB

Pinout & Package

Package: SOT23 - surface-mount plastic case, 0.006g weight, UL 94V-0 rated, moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.

3 (Drain)	High-side current entry point	Connects to switched node (e.g., buck converter inductor); handles 20V max blocking and 8A pulsed current

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2020LFG-7	R_DS(ON) = 0.115Ω @ 4.5V (lower gate threshold dependency), but Q_g = 4.2nC (33% higher than ZXMN2A01FTC)	Better for 3.3V-only gate drive; higher Q_g increases driver loss above 500kHz	Prefer when gate voltage is fixed at 3.3V and switching frequency <500kHz
AO3400	R_DS(ON) = 0.042Ω @ 10V (lower on-resistance), but not AEC-Q101 qualified and R_θJA = 190°C/W (worse thermal performance)	Suitable for consumer-grade DC-DC, not automotive environments requiring −40°C to +125°C operation	Choose only for cost-sensitive non-automotive designs where thermal margin is sufficient

Compared with DMN2020LFG-7 and AO3400, ZXMN2A01FTC offers optimal balance of AEC-Q101 compliance, 2.5V logic compatibility, and 3.0nC gate charge-making it preferred for automotive and industrial 12V systems requiring both reliability and high-frequency efficiency.

FAQ

Is ZXMN2A01FTC suitable for 3.3V microcontroller gate drive?

Yes. With V_GS(th) minimum of 0.7V and guaranteed enhancement at V_GS = 2.5V, the device fully turns on using standard 3.3V GPIO outputs. At V_GS = 3.3V, R_DS(ON) is typically 0.225Ω (measured at 2.5V), delivering 1.5A continuous current within thermal limits on standard FR-4 PCB.

What is the maximum safe operating frequency in a buck converter?

Based on t_D(on) = 2.49ns, t_r = 5.21ns, t_D(off) = 7.47ns, and t_f = 4.62ns, total switching time is ~19.8ns. For 50% duty cycle, maximum practical frequency is ~25MHz, but real-world limit is set by gate drive capability and layout parasitics-typically 1–2MHz with standard drivers and optimized PCB layout.

Does ZXMN2A01FTC have an integrated ESD protection diode?

No. The device does not include on-chip ESD protection diodes between gate and source or gate and drain. External 1kΩ current-limiting resistor and/or TVS diode on the gate line is recommended for systems exposed to IEC 61000-4-2 level 4 (±8kV contact) environments.

Can ZXMN2A01FTC be used in parallel configurations?

Yes, but with caution. Its positive temperature coefficient of R_DS(ON) supports current sharing; however, mismatched PCB trace inductance or thermal coupling may cause imbalance. Use matched gate resistors (≤10Ω), symmetrical layout, and thermal vias under each device's drain pad to maintain ≤10% current deviation at 2A per device.
