2N7000G Description

The 2N7000G from onsemi is an N-channel enhancement-mode MOSFET designed for low-power switching applications. With a drain-to-source voltage (Vdss) rating of 60V and a continuous drain current (Id) of 200mA at 25°C, this transistor is optimized for efficiency in compact circuits. It features a low threshold voltage (Vgs(th)) of 3V max @ 1mA, making it compatible with logic-level signals. The device is housed in a TO-92-3 package, offering ease of integration in through-hole designs. Although marked as obsolete, it remains a reliable choice for legacy systems due to its robust performance and REACH compliance.

2N7000G Features

• Low On-Resistance: 5Ω max @ 500mA, 10V (Rds(on)), ensuring minimal power loss in switching applications.
• Fast Switching: Low input capacitance (Ciss) of 60pF @ 25V reduces gate charge requirements, enhancing speed.
• High Voltage Tolerance: Vgs(max) of ±20V and 60V Vdss provide durability in varied environments.
• Wide Drive Voltage Range: Operates efficiently at 4.5V to 10V gate drive, accommodating both low and standard TTL/CMOS levels.
• Thermal Stability: 350mW power dissipation (Tc) ensures reliable performance under thermal stress.

2N7000G Applications

Ideal for low-current, high-voltage switching, the 2N7000G excels in:

• Signal Switching: Relay/motor drivers, analog switches, and multiplexers.
• Load Control: LED drivers, small DC motor control, and power management in portable devices.
• Logic Interfaces: Level shifting for microcontrollers or GPIO expansion.
• Legacy Systems: Maintenance or repairs of older electronics where modern SMD alternatives are unsuitable.
