Product details

Overview

SN7002WH6433XTMA1 from Infineon Technologies is an N-channel enhancement-mode MOSFET rated for 60 V V_DS, 230 mA continuous drain current, and 1.5 Ω R_DS(on) at V_GS = 10 V, housed in a compact SOT-323 (SC-70) package. It serves as a low-side load switch in space-constrained power management circuits such as USB port protection and LED bias control.

For engineers reviewing the SN7002WH6433XTMA1 datasheet, SN7002WH6433XTMA1 pinout, SN7002WH6433XTMA1 application, or SN7002WH6433XTMA1 equivalent, key selection criteria include its 60 V breakdown voltage, low gate threshold (1–2.5 V), 1.5 Ω on-resistance at 10 V drive, SOT-323 thermal performance, and suitability for 3.3 V logic-level gate drive in portable electronics.

Technical Context

This MOSFET employs planar silicon technology with optimized channel geometry to achieve stable R_DS(on) across temperature and gate voltage. Its gate threshold voltage range (1.0–2.5 V) ensures reliable turn-on with 3.3 V microcontroller I/O, while the 60 V V_DS rating supports operation in 24 V industrial auxiliary rails and 48 V PoE-powered subsystems.

The device features a fully characterized safe operating area (SOA) up to 100 µs pulse width and includes built-in ESD protection (HBM > 2 kV). Its SOT-323 package delivers 190 mW power dissipation at T_A = 25 °C, enabling use without heatsinking in low-duty-cycle switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 24 V system rails with 150 % safety margin against transients
I_D (continuous)	230 mA - sufficient for driving small solenoids, status LEDs, or sensor bias networks
R_DS(on) @ V_GS = 10 V	1.5 Ω - limits conduction loss to <80 mW at 230 mA, minimizing self-heating
V_GS(th)	1.0–2.5 V - compatible with 3.3 V GPIO without level-shifting circuitry
P_D @ T_A = 25 °C	190 mW - enables direct PCB mounting in thermally isolated zones of wearables
C_iss	35 pF - reduces gate drive energy requirement, easing MCU GPIO sourcing capability

Pinout & Package

Package: SOT-323 (SC-70), 3-pin surface-mount plastic package with standard lead finish and moisture sensitivity level MSL3.

Pin/Terminal	Circuit Role	Design Meaning
1 (Source)	Current return path for drain-to-source conduction	Internally connected to die substrate; requires low-impedance PCB ground plane for thermal and EMI control
2 (Gate)	Control electrode modulating channel conductivity	High-impedance input; requires <100 pF trace capacitance to avoid ringing during fast switching
3 (Drain)	High-side current entry point into channel	Connected to load supply rail; layout must minimize parasitic inductance to suppress voltage overshoot

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Guaranteed turn-on with 3.3 V microcontroller outputs, eliminating external level shifters
Low R_DS(on) at 4.5 V	2.2 Ω - maintains <120 mW conduction loss even under 3.3 V/4.5 V supply-limited gate drive
ESD robustness	HBM > 2 kV - withstands handling and board assembly without additional protection diodes
Thermal resistance R_θJA	660 K/W - enables operation up to 85 °C ambient in thin PCB designs with minimal copper area

Applications

LED Bias Control

Use Scenario: Isolating downstream USB peripherals during overcurrent or hot-plug events.

IC Role / Device Role / Timing Role: Low-side power switch controlling VBUS path integrity.

Use Value: Fast turn-off (<100 ns) prevents fault propagation; 60 V rating absorbs USB 2.0/3.0 transient surges.

Use Scenario: Providing constant-current bias to indicator or status LEDs in battery-powered IoT nodes.

IC Role / Device Role / Timing Role: Linear-mode current regulator via gate voltage tuning.

Use Value: 230 mA rating supports multi-LED strings; low R_DS(on) minimizes dropout voltage below 0.4 V.

Microcontroller I/O Expansion

Use Scenario: Extending GPIO count to drive external relays or optocouplers in PLC I/O modules.

IC Role / Device Role / Timing Role: Digital output buffer amplifying weak MCU drive capability.

Use Value: 1.5 Ω R_DS(on) ensures full 3.3 V swing across 10 kΩ loads; SOA validated for 100 µs pulses.

Use Scenario: Supplying regulated excitation current to RTD or bridge-based pressure sensors.

IC Role / Device Role / Timing Role: Precision current source controlled by DAC-adjusted gate voltage.

Use Value: Gate threshold stability (±0.3 V over –40 to +125 °C) maintains sensor bias accuracy across temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel low-voltage switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BSS138W,115 (Nexperia)	V_DS = 50 V, R_DS(on) = 3.5 Ω @ 10 V, higher threshold (0.8–1.5 V)	Limited to ≤24 V systems; less margin for surge immunity	Prefer when cost sensitivity outweighs 60 V headroom needs
DMN2004K-7 (Diodes Inc.)	V_DS = 20 V, R_DS(on) = 2.8 Ω @ 4.5 V, SOT-23 package	Not suitable for 24/48 V auxiliary rails due to lower breakdown	Select only for 3.3/5 V-only domains where smaller footprint is critical

Compared with BSS138W and DMN2004K-7, SN7002WH6433XTMA1 provides superior voltage margin for industrial transients, lower on-resistance at 10 V, and tighter V_GS(th) distribution-making it optimal for mixed-rail systems requiring single-part consolidation.

FAQ

Is SN7002WH6433XTMA1 suitable for 3.3 V logic-level gate drive?

Yes. Its guaranteed gate threshold voltage range of 1.0–2.5 V ensures full enhancement with standard 3.3 V CMOS outputs. At V_GS = 3.3 V, R_DS(on) is typically 2.8 Ω, supporting 230 mA with <200 mW conduction loss. No external level shifter is required.

What is the maximum pulsed drain current rating?

The absolute maximum pulsed drain current is 920 mA for pulse widths ≤100 µs and duty cycle ≤1 %, as defined in the Safe Operating Area (SOA) curve. This allows short-duration inrush current handling for capacitive loads without thermal runaway.

Does SN7002WH6433XTMA1 have integrated body diode recovery protection?

No. It features a standard parasitic body diode with reverse recovery time t_rr = 25 ns (typical) at I_F = 100 mA. For high-frequency flyback or synchronous rectification, external Schottky clamping is recommended to limit voltage spikes.

Can SN7002WH6433XTMA1 be used in linear mode for current regulation?

Yes. Its SOA is fully specified down to DC, supporting linear operation with ≤190 mW power dissipation at 25 °C ambient. When biased with precision gate voltage, it delivers stable current regulation for sensor excitation or LED biasing with ±2 % accuracy over temperature.
