Product details

Overview

2N7002TA from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT23 package, rated for 60V V_DSS, 5Ω R_DS(ON) @ V_GS = 10V, and 210mA I_D at T_A = +25°C. It delivers low gate threshold (1.0–2.5V), fast switching (t_F = 5.6ns), and low input capacitance (C_iss = 22pF), enabling efficient load switching in space-constrained power management circuits.

For engineers reviewing the 2N7002TA datasheet, 2N7002TA pinout, 2N7002TA application, or 2N7002TA equivalent, key selection criteria include verified R_DS(ON) at 5V drive, thermal resistance (R_θJA = 241°C/W on 1"×1" 2oz Cu), JEDEC-qualified reliability, and SOT23 terminal layout compatibility with automated assembly.

Technical Context

This discrete MOSFET operates as a low-voltage, low-current single-pole switch with enhancement-mode gate control. Its 1.0–2.5V V_GS(TH) enables direct interfacing with 3.3V/5V logic, while its 223pC total gate charge supports clean turn-on under moderate drive strength.

The device uses planar silicon process with optimized channel geometry to balance R_DS(ON) and switching speed. Its body diode exhibits V_SD = 0.78V @ I_S = 115mA, supporting bidirectional current handling in flyback or reverse-polarity protection topologies.

Key Specifications

V_DSS	60V - Supports rail voltages up to 48V DC systems with margin for transients
R_DS(ON)	5Ω @ V_GS = 10V - Limits conduction loss to <5mW at 100mA load current
I_D Max	210mA @ T_A = +25°C - Suitable for signal-level switching and LED biasing
V_GS(TH)	1.0–2.5V - Ensures reliable turn-on from standard microcontroller GPIOs
C_iss	22pF typical - Reduces gate drive power and enables >1MHz switching in low-power SMPS
t_F	5.6ns - Enables sharp edge transitions in timing-critical digital load control
P_D	540mW on 1"×1" 2oz Cu PCB - Allows continuous operation at ~150mA with <50°C junction rise

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
DMN2004K-7	R_DS(ON) = 3.5Ω @ V_GS = 4.5V; higher I_D = 300mA	Better suited for 3.3V logic-driven loads above 150mA	Select when lower on-resistance at 4.5V is required and board space permits same SOT23 footprint
BS170	V_DSS = 60V but R_DS(ON) = 5Ω @ V_GS = 10V; slower t_F = 20ns	Legacy through-hole TO-92 version; not SMT-compatible	Choose only for prototyping or legacy repair where SOT23 rework is impractical

Compared with DMN2004K-7 and BS170, the 2N7002TA offers optimal balance of 5V-compatible threshold, JEDEC qualification, and SOT23 manufacturability-making it preferred for new designs targeting automated assembly and automotive-adjacent reliability.

FAQ

What is the maximum continuous drain current for 2N7002TA at 85°C ambient?

The maximum continuous drain current is 150mA at T_A = +85°C when mounted on a 1"×1" FR-4 PCB with 2oz copper. This derating reflects thermal resistance (R_θJA = 241°C/W) and junction temperature limit of +150°C. Operation above this current requires heatsinking or forced airflow.

Does 2N7002TA support 3.3V logic-level gate drive?

Yes - its gate threshold voltage range (1.0–2.5V) ensures full enhancement with 3.3V logic outputs. At V_GS = 3.3V, R_DS(ON) is typically 9.5Ω (per interpolation of Fig. 4), delivering ~330mV drop at 35mA - sufficient for most signal-switching applications.

Is 2N7002TA qualified for automotive applications?

No - the standard 2N7002TA is not AEC-Q101 qualified. Diodes offers the automotive-grade 2N7002Q variant, which undergoes additional stress testing per AEC-Q101 and is documented in a separate datasheet (DS11304). Use 2N7002Q for automotive ECUs or infotainment systems.

What is the recommended PCB pad layout for SOT23 mounting?

Diodes specifies a pad layout with X = 0.8mm, Y = 0.9mm, X1 = 1.35mm, Y1 = 2.9mm, and C = 2.0mm (center-to-center). This layout ensures solder joint reliability and thermal performance matching the 540mW power rating on 2oz copper. Full dimensions are published in Diodes' SOT23 package outline document.
