Product details

Overview

2N7002W-7 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT-323 package, rated for 60V V_DSS, 7.5Ω R_DS(on) at V_GS = 5V, and 115mA continuous drain current at T_A = +25°C. It serves as a low-power switching device in compact DC-DC converters, LED drivers, and load-switching circuits where space and efficiency are critical.

For engineers reviewing the 2N7002W-7 datasheet, 2N7002W-7 pinout, 2N7002W-7 application, or 2N7002W-7 equivalent, key selection criteria include gate threshold voltage (1.0–2.0V), ultra-low input capacitance (C_iss = 22–50pF), thermal resistance (R_θJA = 625°C/W), and JEDEC-qualified reliability for industrial and automotive-adjacent designs.

Technical Context

This MOSFET employs planar silicon-gate technology to achieve low on-resistance while maintaining fast switching speed (t_D(on) ≤ 20ns, t_D(off) ≤ 20ns) and low gate charge. Its ±20V gate-source voltage rating supports direct interfacing with 3.3V and 5V logic controllers without level-shifting.

The device operates across –55°C to +150°C junction temperature range and features low input/output leakage (I_DSS ≤ 1.0µA at 25°C, ≤500µA at 125°C; I_GSS ≤ ±10nA), enabling stable performance in thermally constrained environments such as portable power management ICs and sensor interface modules.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60V - Supports rail voltages up to 48V systems with margin for transients.
R_DS(on)	7.5Ω @ V_GS = 5V - Enables efficient low-current switching in battery-powered loads.
I_D (continuous)	115mA @ T_A = +25°C - Suitable for signal-level switching and bias control, not high-power loads.
C_iss	22–50pF - Minimizes gate drive power and enables clean edge transitions in 1–10MHz switching.
V_GS(th)	1.0–2.0V - Ensures reliable turn-on with standard GPIO outputs (3.3V/5V).
R_θJA	625°C/W - Requires minimal PCB copper area for thermal management in SOT-323 footprint.
P_D	200mW @ T_A = +25°C - Limits usable power dissipation to ~100mW in typical FR-4 layouts.

Pinout & Package

SOT-323 (Standard) ultra-small surface-mount package: 1.8–2.2mm × 2.0–2.45mm × 0.9mm height, moisture sensitivity level 1, lead-free and RoHS-compliant.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2004K-7	R_DS(on) = 3.5Ω @ V_GS = 4.5V; higher ID (220mA); SOT-23 package	Larger footprint; better suited for higher-current loads (>150mA)	Select when lower conduction loss is prioritized over board space.
BSS138W-7-F	R_DS(on) = 3.5Ω @ V_GS = 10V; V_DSS = 50V; same SOT-323 package	Lower breakdown voltage; requires tighter input voltage derating	Prefer when gate drive is 10V and 50V system margin is acceptable.

Compared with DMN2004K-7 and BSS138W-7-F, the 2N7002W-7 offers optimal balance of ultra-compact size, 60V tolerance, and 3.3V-compatible gate drive-making it ideal for space-constrained, low-power logic-controlled switching where thermal budget is limited to <200mW.

FAQ

Is the 2N7002W-7 suitable for 3.3V microcontroller GPIO direct drive?

Yes. With a gate threshold voltage of 1.0–2.0V and guaranteed turn-on at V_GS = 3.3V, the 2N7002W-7 switches fully with standard 3.3V logic outputs. Its low input capacitance (22–50pF) ensures minimal loading and fast edge response without external gate resistors in most cases.

What is the maximum safe operating temperature for continuous use?

The junction temperature must not exceed +150°C. At ambient +25°C, the 200mW power limit and 625°C/W thermal resistance allow only ~125mW continuous dissipation in standard FR-4 layouts. Derating is required above +25°C ambient-e.g., ~73mA max I_D at +100°C ambient per datasheet ratings.

Does the 2N7002W-7 meet automotive qualification requirements?

No-the 2N7002W-7 is an industrial-grade part qualified to JEDEC standards and AEC-Q101 *stress test methods*, but it is not PPAP-capable nor manufactured in IATF 16949-certified facilities. For automotive use, select the Q-suffix variant (e.g., 2N7002WQ-7) listed in Diodes' automotive products portal.

Can this MOSFET replace a BJT in low-side switching applications?

Yes-its low V_GS(th), high input impedance, and absence of base current make it superior to BJTs for logic-driven switching. Unlike BJTs, it requires no base resistor and exhibits lower saturation voltage at light loads (<25mA), reducing heat generation and simplifying drive circuitry.
