Product details
Overview
ZXMN3B01FTC from Diodes Incorporated (formerly Zetex Semiconductors) is a 30V N-channel enhancement-mode Trench MOSFET in SOT-23 package, rated for 2.0A continuous drain current at VGS=4.5V, with RDS(on) = 0.150Ω (typ), VGS(th) = 0.7V, and fast switching (td(on) = 2.69ns, Qg = 2.93nC), used in low-voltage DC-DC converter power stages.
For engineers reviewing the ZXMN3B01FTC datasheet, ZXMN3B01FTC pinout, ZXMN3B01FTC application, or ZXMN3B01FTC equivalent, key selection criteria include gate threshold voltage compatibility with 2.5V–4.5V logic-level drivers, thermal performance on FR4 PCBs (RJA = 155°C/W), body diode recovery (trr = 10.85ns), and SOT-23 footprint constraints in space-constrained power management designs.
Technical Context
This MOSFET employs a trench-gate structure optimized for low RDS(on) and high transconductance (gfs = 4S at VDS = 15V, ID = 1.7A), enabling efficient operation in synchronous buck converters and load switches where conduction loss and gate drive energy are critical.
Its 2.5V gate drive capability supports direct interfacing with low-voltage microcontrollers and PMIC outputs; dynamic parameters-including Ciss = 258pF, Coss = 50pF, and Qgd/Qgs ratio of ~1.6-indicate strong immunity to Miller-induced shoot-through in high-frequency switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30V - Maximum blocking voltage compatible with 24V rail and 12V automotive systems. |
| RDS(on) | 0.150Ω @ VGS=4.5V, ID=1.7A - Enables <150mW conduction loss at 1.7A, critical for thermally constrained SOT-23 layouts. |
| ID (cont) | 2.0A @ TA=25°C, VGS=4.5V - Supports medium-current load switching without external heatsinking on standard PCBs. |
| VGS(th) | 0.7V (min), 1.0V (typ) - Ensures reliable turn-on with 1.8V/2.5V logic families and low-power controllers. |
| Qg | 2.93nC @ VDS=15V, VGS=4.5V - Low gate charge reduces driver power loss and enables >1MHz PWM operation with minimal gate drive strength. |
| trr | 10.85ns @ IF=1.3A, di/dt=100A/μs - Fast body diode recovery minimizes reverse recovery loss in non-synchronous flyback or buck-boost converters. |
| PD | 806mW @ TA=25°C (RJA=155°C/W) - Defines maximum steady-state power dissipation before junction exceeds 150°C on typical FR4 layout. |
Pinout & Package
SOT-23 package: surface-mount, 3-pin plastic case with gull-wing leads; standardized footprint per JEDEC TO-236AB; thermal pad not present; mounting requires solder reflow profile compatible with 260°C peak.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Source) | Current return path for channel conduction and body diode anode | Connected to ground or low-side reference; must handle full load current and body diode reverse recovery stress. |
| 2 (Gate) | Control electrode for channel inversion | High-impedance input requiring low-capacitance routing; sensitive to noise coupling due to Ciss=258pF and low VGS(th). |
| 3 (Drain) | Main current output terminal and body diode cathode | Connected to switched node (e.g., buck converter inductor); exposed copper area improves thermal transfer but adds parasitic capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Trench-gate architecture | Delivers 0.150Ω RDS(on) in SOT-23, enabling higher efficiency than planar MOSFETs of same size at 1–2A loads. |
| 2.5V logic-compatible gate drive | Guaranteed turn-on with 2.5V CMOS outputs, eliminating need for level-shifting in battery-powered microcontroller interfaces. |
| Low Qgd/Qg ratio (0.31) | Reduces risk of false turn-on during high dv/dt events, improving reliability in hard-switching applications like motor gate drivers. |
| Fast body diode (trr = 10.85ns) | Minimizes energy loss and voltage overshoot during freewheeling in non-synchronous topologies without external Schottky. |
| JEDEC-standard SOT-23 footprint | Enables drop-in replacement in existing designs using industry-common pick-and-place and reflow processes. |
Applications

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 |
|---|---|---|---|
| DMN2004LK-7 | RDS(on) = 0.125Ω @ VGS=4.5V; higher ID = 2.8A; slightly larger Ciss = 290pF | Better conduction efficiency at >2A loads; marginally slower switching due to higher input capacitance | Preferred when board space allows SOT-23-3 with tighter RDS(on) tolerance and higher current headroom. |
| AO3400 | RDS(on) = 0.042Ω @ VGS=10V but 0.055Ω @ VGS=4.5V; VGS(th) = 1.0V (min); Qg = 7.5nC | Requires stronger gate drive for full enhancement; higher gate charge increases driver loss at high frequency | Choose only if system uses 5V logic and prioritizes ultra-low RDS(on) over gate drive simplicity and switching speed. |
Compared with DMN2004LK-7 and AO3400, ZXMN3B01FTC offers the best balance of low gate threshold (0.7V), moderate gate charge (2.93nC), and proven thermal performance in SOT-23-making it optimal for 2.5V–4.5V-driven, space-constrained, medium-current power switches where driver simplicity and EMI control are critical.

FAQ
What is the maximum safe operating junction temperature for ZXMN3B01FTC?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation across –55°C to +150°C. Derating begins at 25°C ambient with a linear factor of 6.4 mW/°C when mounted on FR4 PCB per specification (b), ensuring safe thermal margin up to 125°C ambient at reduced power.
Can ZXMN3B01FTC be used in a high-side switch configuration?
Yes, but only with appropriate gate drive circuitry that provides VGS ≥ 4.5V relative to the source node. Since it is an N-channel device, high-side use requires a charge pump or bootstrap gate driver to elevate the gate voltage above the drain rail-unlike P-channel alternatives which simplify high-side implementation.
Does ZXMN3B01FTC have built-in ESD protection?
No. The datasheet does not specify on-chip ESD protection structures. Standard handling precautions (IEC 61000-4-2 Level 2 or higher) are required during assembly; external TVS or RC filtering is recommended on gate and drain lines in noisy environments to prevent latch-up or oxide damage.
Is the SOT-23 package lead-free and RoHS compliant?
Yes. ZXMN3B01FTC is manufactured in accordance with Diodes Incorporated's RoHS-compliant process and carries lead-free (Pb-free) terminations. The device meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and is qualified for standard SnPb and Pb-free reflow profiles up to 260°C peak.
