Product details

Overview

ZXMN3A01FTC from Diodes Incorporated is a 30V N-channel enhancement-mode MOSFET in SOT23 package, with R_DS(ON) = 0.12 Ω @ V_GS = 10 V, I_D = 2.0 A at T_A = +25°C, and V_GS(th) = 1–2.5 V. It serves as a low-side power switch in compact DC-DC converters and motor control stages where low gate drive and fast switching are required.

For engineers reviewing the ZXMN3A01FTC datasheet, ZXMN3A01FTC pinout, ZXMN3A01FTC application, or ZXMN3A01FTC equivalent, key selection criteria include its 0.12 Ω on-resistance at 10 V gate drive, 2.3 nC total gate charge, 17.7 ns reverse recovery time, SOT23 thermal resistance of 200 °C/W (on 25 mm × 25 mm FR-4), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This MOSFET employs planar silicon process technology optimized for low R_DS(ON) while preserving fast switching performance via minimized gate charge (Q_g = 3.9 nC) and low output capacitance (C_oss = 38 pF). Its 1–2.5 V gate threshold enables compatibility with 3.3 V and 5 V logic-level drivers.

The device integrates a body diode with V_SD = 0.85–0.95 V at I_S = 1.7 A and exhibits t_r = 2.3 ns / t_f = 2.9 ns switching transitions under 15 V V_DD, 2.5 A load, and 6 Ω gate resistance - confirming suitability for high-frequency synchronous rectification and PWM-driven loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - supports input rails up to 24 V nominal systems with margin
R_DS(ON)	0.12 Ω @ V_GS = 10 V - limits conduction loss to ≤600 mW at 2.0 A continuous
I_D	2.0 A @ T_A = +25°C - rated for sustained current in thermally constrained SOT23 layouts
Q_g	3.9 nC @ V_GS = 10 V - enables efficient 1–2 MHz switching with low driver power demand
V_GS(th)	1–2.5 V - ensures turn-on with standard 3.3 V microcontroller GPIOs
t_r/t_f	2.3 ns / 2.9 ns - reduces switching transition losses in high-frequency power stages
R_θJA	200 °C/W - defines thermal derating to 625 mW on standard 25 mm × 25 mm FR-4 PCB

Pinout & Package

Package: SOT23 - surface-mount, 3-pin plastic case (UL 94V-0), 0.006 g weight, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Drain (D)	Power output node	Connected to load return path; handles full switched current and dissipates conduction + switching losses
Gate (G)	Control input	Receives logic-level voltage; low 3.9 nC Q_g minimizes driver loading and propagation delay
Source (S)	Reference node	Common return for gate drive and load current; ties to ground or low-side shunt in buck/synchronous rectifier topologies

Key Features

Feature	Design Value
Low R_DS(ON)	0.12 Ω @ 10 V enables <600 mW conduction loss at 2 A, critical for space-constrained power stages
Fast switching	2.3 ns rise / 2.9 ns fall times reduce transition losses in >500 kHz DC-DC designs
Logic-level gate drive	V_GS(th) max 2.5 V ensures reliable turn-on with 3.3 V MCU outputs without level-shifting
AEC-Q101 qualified	Validated for automotive temperature range (−55°C to +150°C) and mechanical stress requirements

Applications

DC-DC Converters

Motor Control

Use Scenario: Synchronous rectifier in 3.3 V/5 V buck converter for portable electronics.

IC Role / Device Role / Timing Role: Low-side power switch replacing Schottky diode to improve efficiency by reducing forward drop.

Use Scenario: H-bridge half-bridge leg in 12 V brushed DC motor driver for automotive HVAC actuators.

IC Role / Device Role / Timing Role: Low-side switch controlling motor winding current direction and PWM duty cycle.

Use Value: 2.5 V V_GS(th) max allows direct drive from automotive microcontroller GPIOs, eliminating external level shifters.

Power Management Functions

Load Switching

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	R_DS(ON) = 0.035 Ω @ 10 V (lower), but SOT23-6 package with dual MOSFET topology	Requires redesign for dual-channel layout; not pin-compatible	Select when lower on-resistance justifies extra board area and routing complexity
AO3400	R_DS(ON) = 0.028 Ω @ 10 V, Q_g = 12 nC (higher), V_GS(th) = 0.7–1.4 V (lower)	Higher gate charge increases driver loss at >1 MHz; tighter V_GS(th) improves 1.8 V logic compatibility	Prefer for ultra-low R_DS(ON) needs below 1 A, but verify gate driver capability for 12 nC charge

Compared with DMN3025LSD-13 and AO3400, ZXMN3A01FTC offers balanced R_DS(ON), gate charge, and threshold voltage in a single-channel SOT23 - making it optimal for cost-sensitive, space-constrained 2 A switching nodes where moderate efficiency and simple layout are prioritized.

FAQ

What is the maximum continuous drain current at 70°C ambient?

The ZXMN3A01FTC supports 1.6 A continuous drain current at T_A = +70°C, per its Absolute Maximum Ratings table. This derating reflects thermal limitations of the SOT23 package on standard FR-4 PCBs, where junction temperature must remain below 150°C under steady-state conditions.

Is this MOSFET suitable for 3.3 V microcontroller gate drive?

Yes - with V_GS(th) specified from 1.0 V to 2.5 V and R_DS(ON) = 0.18 Ω at V_GS = 4.5 V, the device fully turns on using 3.3 V logic. At 2 A load, conduction loss remains ≤720 mW, well within its 625 mW P_D rating at T_A = +25°C with proper PCB copper area.

Does ZXMN3A01FTC include an integrated body diode?

Yes - it features an inherent parasitic body diode with forward voltage V_SD = 0.85–0.95 V at I_S = 1.7 A and T_J = +25°C. Reverse recovery time is 17.7 ns, supporting use in synchronous rectification and freewheeling paths where fast recovery is needed.

What is the moisture sensitivity level and reflow profile compliance?

ZXMN3A01FTC is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/85% RH and requires no baking prior to standard lead-free reflow. Its matte tin finish and SOT23 package are compatible with IPC/JEDEC J-STD-020D peak temperature profiles up to 260°C.
