2N7000 N-Channel MOSFET Transistor (TO-92) ⚡

The 2N7000 is a compact, general-purpose N‑channel MOSFET in a TO‑92 package, ideal for low-power switching and signal-level tasks in Arduino, Raspberry Pi, and other microcontroller-based projects. Known for its fast switching, low on-resistance, and robust voltage handling, it’s a reliable choice for prototyping and embedded electronics designs.

Key Features 🔧

• Rapid switching for efficient digital control and PWM applications
• Low on-resistance (Rds(on)) for reduced conduction losses
• Low gate threshold voltage suitable for logic-level driving in many use cases
• High drain–source voltage capability for flexible designs
• Compact TO‑92 package — breadboard‑friendly and easy to integrate
• Well-suited for modules, electronics components kits, and educational projects

Technical Specifications 📐

• Drain–Source Voltage (Vds): 60 V
• Gate–Source Voltage (Vgs): ±20 V (max)
• Continuous Drain Current (Id): 200 mA
• Power Dissipation (Pd): 400 mW
• Operating Temperature: −55°C to +150°C
• Package: TO‑92 (through‑hole)

Note: For best results with 3.3 V logic (e.g., Raspberry Pi), limit load current or verify Rds(on) at your drive voltage. For higher currents at low gate drive, consider a dedicated logic‑level MOSFET.

Typical Applications 🧩

• Power management in consumer and embedded electronics
• Low-side switching for LEDs, small relays, and signal loads
• Signal amplification and level shifting
• Motor control for small DC motors (with appropriate flyback protection)
• Signal processing and digital interfacing with microcontrollers such as Arduino and Raspberry Pi

Design Tips for Microcontroller Projects 💡

• Use a gate resistor (e.g., 100–330 Ω) to tame switching transients.
• Add a gate pull‑down (e.g., 100 kΩ) to keep the MOSFET off during reset.
• For inductive loads (motors, relays), include a flyback diode across the load.
• Implement proper thermal management and stay within absolute maximum ratings.
