IR Tx Led (White)

PT-333C-A IR Tx Led (White)
This LED is engineered to be the perfect match for the PT-333-3B Photodiode. Together, they form an invisible link that can detect movement, measure speed, or transmit data across a room.

 
Why it’s a Robotics & Control Essential:
• Invisible Operation: Because it operates at 940nm, it won't distract users or create visual "noise" in your project. This is essential for discreet security systems or smart home devices.
• Focused Beam: The narrow 20° angle allows the IR light to travel further and reflect more reliably off distant objects compared to wide-angle LEDs.
• High Pulsing Capacity: While its continuous current is 20mA, it can handle short "bursts" or pulses of up to 100mA. This is how remote controls achieve long distances—by flashing very brightly for a fraction of a second.
• Standard 5mm Form Factor: It fits into any standard LED holder or breadboard, making it easy to swap into existing designs.

 
Technical Capabilities:
• Peak Wavelength: 940 nm (The standard for IR remotes and proximity sensors).
• Forward Voltage ($V_F$): Approximately 1.2V (Lower than red or green LEDs, meaning it's very energy efficient).
• High Radiant Intensity: Designed to provide a strong signal even through plastic enclosures or IR-pass filters.

 
Best For:
The PT-333C-A is the primary choice for TV remote control repairs, optical beam-break sensors, 3D-printed gesture boxes, and infrared illuminators for small night-vision cameras.
