Bipolar (BJT) Transistor – NPN 36 V

This is a 3‑terminal NPN bipolar junction transistor (BJT) rated for up to about 36 V across the collector–emitter, commonly used as a small‑signal switch or amplifier in hobby and general‑purpose circuits. It controls a larger current between collector and emitter with a much smaller current into the base, making it useful for driving LEDs, small relays, or other loads from a microcontroller.

Typical role and use

• Type: NPN general‑purpose BJT, often in a TO‑92 or similar small through‑hole package.
• Voltage rating: Up to 36 V collector–emitter breakdown voltage (VCE max), so it suits many low‑voltage DC‑supply projects.
• Function: Can work in switching (on/off) or amplifier (active) mode, depending on the circuit.

Typical applications

• Turning on/off LEDs, small motors, or low‑power relays from a microcontroller’s 3.3 V or 5 V output.
• Basic signal‑level amplification stages in audio or sensor circuits.

Note: Exact part number (for example, something like a 2N3904‑style or LM395T‑style NPN) and current/power rating depend on the specific device; check the datasheet for precise values.
