Key Features
- High Current Capability: Handles up to 600mA continuous collector current, making it suitable for driving relays, small motors, LEDs, and other moderate-load devices.
- Excellent Switching Speed: With a transition frequency of 300 MHz, the 2N2222A excels in fast-switching applications and high-frequency circuits.
- Wide DC Current Gain Range: hFE of 100-300 provides flexible amplification for analog signal processing and digital logic interfacing.
- The Engineer Store Voltage Ratings: 40V collector-emitter and 75V collector-base voltage ratings offer generous headroom for a variety of circuit designs.
- Industry-Standard TO-92 Package: Compact, breadboard-friendly, and easy to solder onto perfboards and custom PCBs.
- Wide Operating Temperature: Functions reliably from -55 degreesC to +150 degreesC, suitable for demanding environmental conditions.
- Low Saturation Voltage: Ensures efficient switching with minimal power loss in saturated (fully ON) state.
- Pack of 5: Convenient multi-pack keeps your inventory stocked for ongoing projects and quick replacements.
Why Choose the 2N2222A from The Engineer Store?
- 100% Authentic Components: Every transistor is sourced directly from authorized distributors and verified for authenticity - no counterfeits, no rejects.
- Fast 1-5 days shipping: Ships from our Bengaluru warehouse to most locations across India. Same-day delivery available within Bengaluru.
- Expert Technical Support: Our engineering team is available 24/7 via email and WhatsApp to help with circuit design questions, troubleshooting, and component selection.
- Trusted by Professionals & Students: Used by thousands of engineers, makers, and institutions across India for reliable project outcomes.
- Quality Tested: Each batch undergoes inspection to ensure electrical parameters meet datasheet specifications.
Project Ideas & Applications
- Relay Driver Circuit: Use the 2N2222A to switch a 5V or 12V relay from a microcontroller GPIO pin (Arduino, ESP32, Raspberry Pi). Add a flyback diode across the relay coil and a 1kOhm base resistor for a clean, reliable driver stage.
- LED Driver / Current Amplifier: Drive high-brightness LEDs or LED strips that draw more current than a microcontroller pin can supply. The transistor acts as a current amplifier, controlled by a small base signal.
- Motor Speed Control: Pair with a PWM signal from an Arduino to control the speed of small DC motors. Combine with an H-bridge configuration using complementary PNP transistors for bidirectional control.
- Audio Preamplifier: Build a common-emitter amplifier stage
