NXP Semiconductors 2N7002BKT,115

Overview

2N7002BKT from Nexperia is an N-channel enhancement-mode Trench MOSFET in SOT416 (SC-75) package, rated for 60 V drain-source voltage, 290 mA continuous drain current at 25 °C, and 1.0 Ω typical R_DS(on) at V_GS = 10 V. It serves as a low-side load switch or high-speed line driver in compact power management circuits.

For engineers reviewing the 2N7002BKT datasheet, 2N7002BKT pinout, 2N7002BKT application, or 2N7002BKT equivalent, this page delivers verified electrical parameters, thermal behavior, AEC-Q101 qualification status, ESD robustness (2 kV HBM), and logic-level gate drive compatibility - all critical for automotive and industrial switching designs.

Technical Context

This discrete MOSFET uses Trench MOSFET technology to achieve fast switching (t_d(on) = 5 ns typ., t_f = 7 ns typ.) and low on-resistance with logic-level gate drive (V_GS(th) = 1.1–2.1 V). Its 3-pin SOT416 package supports surface-mount assembly on FR4 PCBs with standard footprint and 1 cm² drain pad for thermal management.

The device operates across −55 °C to +150 °C ambient temperature, with junction temperature limited to 150 °C. It features integrated source-drain diode (V_SD = 0.47–1.1 V at I_S = 115 mA) and exhibits 33–50 pF input capacitance (C_iss) at 10 V V_DS, enabling efficient gate charge control (Q_G(tot) = 0.5–0.6 nC).

FAQ

What is the maximum continuous drain current rating for the 2N7002BKT at 100 °C ambient temperature?

The 2N7002BKT supports 200 mA continuous drain current at T_amb = 100 °C, derated from its 290 mA rating at 25 °C per the normalized current curve in the datasheet. This reflects thermal limitations of the SOT416 package on standard FR4 PCBs without enhanced copper pours.

Does the 2N7002BKT have integrated ESD protection, and what is its rating?

Yes, the 2N7002BKT includes on-chip ESD protection rated at 2000 V per the Human Body Model (HBM), as confirmed in Table 5 of the official Nexperia datasheet. This eliminates the need for external ESD clamps in most board-level implementations.

Is the 2N7002BKT pin-compatible with the industry-standard 2N7002 series?

Yes, the 2N7002BKT shares identical SOT416 (SC-75) pinout (G-S-D) and mechanical dimensions with other 2N7002 variants, including the original 2N7002 and 2N7002E. However, electrical parameters such as R_DS(on) and V_GS(th) differ, so functional substitution requires validation.

What is the gate threshold voltage range for the 2N7002BKT, and how does it affect microcontroller interfacing?

The 2N7002BKT has a gate-source threshold voltage (V_GS(th)) of 1.1–2.1 V at I_D = 250 µA, ensuring full enhancement with 3.3 V or 5 V GPIO outputs. This allows direct drive from most microcontrollers without level-shifting circuitry, simplifying design and reducing BOM count.

Can the 2N7002BKT be used in automotive applications, and what qualification does it hold?

Yes, the 2N7002BKT is AEC-Q101 qualified, confirming its suitability for automotive applications including body control modules, lighting, and infotainment systems. This qualification covers stress testing for temperature cycling, humidity, and mechanical shock per automotive reliability standards.
