Product details

Overview

ZXM62N03E6TA from Zetex (now Diodes Incorporated) is a 30V N-channel enhancement-mode MOSFET in SOT23-6 package, with R_DS(on) = 0.11 Ω @ V_GS = 10V, I_D = 2.2A, and fast switching (t_d(on) = 2.9 ns, Q_g = 9.6 nC). It serves as a low-voltage power switch in compact DC-DC converters and load disconnect circuits.

For engineers reviewing the ZXM62N03E6TA datasheet, ZXM62N03E6TA pinout, ZXM62N03E6TA application, or ZXM62N03E6TA equivalent, key selection criteria include its 0.11 Ω on-resistance at 10V gate drive, 3.2A continuous drain rating at 25°C, body diode forward voltage of 0.95V, and SOT23-6 thermal performance (R_θJA = 73 °C/W under optimized PCB conditions).

Technical Context

This MOSFET employs a high-density planar structure optimized for low R_DS(on) and fast switching-achieving t_r = 5.6 ns and t_f = 6.4 ns with 6.0 Ω gate resistance. Its V_GS(th) = 1.0 V (min) enables compatibility with 3.3V logic-level drive.

The integrated source-drain body diode supports synchronous rectification and reverse-current handling, with t_rr = 18.8 ns and Q_rr = 11.4 nC at I_F = 2.2A and di/dt = 100 A/µs-critical for high-frequency flyback and buck converter operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - Maximum blocking voltage in off-state; suitable for 24V rail and 12V automotive auxiliary systems.
R_DS(on)	0.11 Ω @ V_GS = 10V, I_D = 2.2A - Enables <120 mW conduction loss at 1.1A, critical for thermally constrained SOT23-6 layouts.
I_D (cont)	3.2 A @ T_A = 25°C - Continuous current capability limited by package thermal resistance (73 °C/W) and PCB copper area.
Q_g	9.6 nC - Total gate charge determines driver strength requirement; compatible with low-power gate drivers like TC4420.
V_GS(th)	1.0 V (min) - Ensures turn-on with 1.8V–3.3V microcontroller GPIO, supporting logic-level control without level-shifting.
t_r/t_f	5.6 ns / 6.4 ns - Fast edge rates reduce switching losses in >500 kHz DC-DC topologies.
V_SD	0.95 V @ I_S = 2.2A - Low body diode forward drop improves efficiency in bidirectional or freewheeling paths.

Pinout & Package

SOT23-6 surface-mount package with exposed drain pad (pin 6) for enhanced thermal dissipation. Dimensions per JEDEC MO-178: D = 2.9 mm, E = 2.8 mm, L = 0.35 mm lead length, 0.65 mm pitch.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; requires ≤±20V drive; low C_iss = 380 pF minimizes driver loading.
2 (S)	Source	Reference node for gate drive; tied to ground or low-side return path in high-side configurations.
3 (D)	Drain	Power output node; electrically connected to pin 6 (exposed pad) for thermal and current conduction.
4 (S)	Source	Second source connection; paralleled with pin 2 to reduce source inductance in high-di/dt switching.
5 (G)	Gate	Redundant gate connection; used with pin 1 to lower gate loop inductance and suppress ringing.
6 (D)	Drain (exposed pad)	Primary thermal path to PCB; must be soldered to ≥25 mm² 1 oz copper for rated 1.7 W power dissipation.

Key Features

Feature	Design Value
Low R_DS(on) at 4.5V	0.15 Ω - Enables efficient operation from 5V logic rails without gate boosting.
Fast switching with low Q_gd	2.8 nC - Reduces Miller plateau time, improving hard-switching robustness in synchronous buck stages.
Low threshold voltage	1.0 V min - Guarantees turn-on with standard 1.8V/3.3V I/O, eliminating external level shifters.
Optimized body diode	t_rr = 18.8 ns, Q_rr = 11.4 nC - Minimizes reverse recovery loss in discontinuous conduction mode (DCM) converters.
SOT23-6 thermal design	R_θJA = 73 °C/W - Achievable with minimal PCB copper; supports 1.7 W dissipation in space-constrained designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN3026LSD-13	R_DS(on) = 0.095 Ω @ 10V but higher Q_g = 12.5 nC; SOT23-6 with same pinout.	Better conduction loss at high current, but slower switching increases driver demand.	Prefer for low-frequency, high-current loads where thermal margin > switching loss.
AO3400	R_DS(on) = 0.028 Ω @ 10V, but V_DSS = 30V and Q_g = 17 nC; SOT23-3 (3-pin), no dual-source pins.	Higher current density but lacks redundant source/gate pins and thermal pad; lower layout flexibility.	Prefer only when board space is extreme and thermal constraints allow SOT23-3 mounting.

Compared with DMN3026LSD-13 and AO3400, ZXM62N03E6TA offers balanced R_DS(on), Q_g, and thermal design in SOT23-6-making it optimal for space-limited, medium-frequency (<1 MHz) power switches requiring both efficiency and layout robustness.

FAQ

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

The ZXM62N03E6TA supports 2.6 A continuous drain current at T_A = 70°C, based on its 1.7 W power dissipation rating and 73 °C/W junction-to-ambient thermal resistance. This assumes mounting on FR4 PCB with adequate copper area and still-air conditions per datasheet Note (b).

Can this MOSFET be driven directly from a 3.3V microcontroller GPIO?

Yes. With V_GS(th) = 1.0 V (min) and R_DS(on) = 0.15 Ω at V_GS = 4.5V, the device fully enhances at 3.3V-delivering ~2.0 A continuous current with acceptable on-resistance. Gate capacitance (C_iss = 380 pF) is manageable for typical MCU GPIO slew rates.

Is the SOT23-6 package thermally enhanced compared to standard SOT23-3?

Yes. The SOT23-6 variant includes an exposed drain pad (pin 6) and dual-source/gate terminals, reducing thermal resistance to 73 °C/W (vs. >150 °C/W for SOT23-3). This allows 1.7 W dissipation-more than double typical SOT23-3 limits-when soldered to ≥25 mm² copper.

Does the body diode support reverse recovery in synchronous rectification?

Yes. The integrated body diode has t_rr = 18.8 ns and Q_rr = 11.4 nC at I_F = 2.2A, making it suitable for synchronous rectification in buck converters operating up to 1 MHz. Its low V_SD = 0.95 V further reduces conduction loss during freewheeling.
