IR928-6C-F Infrared Emitter Diode 940nm High Power IR Emission LED

IR928-6C-F Infrared Emitter Diode 940nm High Power IR Emission LED is a crucial component for applications requiring reliable, invisible infrared light generation. This high-power, through-hole LED emits light at a standard 940 nm wavelength, which aligns perfectly with the spectral response of most silicon-based phototransistors and photodiodes used in sensing and remote control systems. Therefore, designers frequently select the IR928-6C-F for its exceptional radiant intensity and narrow viewing angle, which ensures long-distance transmission and precise targeting of the IR beam. Furthermore, its robust T-1 ³/₄ package (5mm standard LED size) offers excellent mechanical stability and easy integration into circuit boards and housings. You can confidently rely on this infrared emitter to drive your most demanding data communication and security projects.

Key Features:

• Peak Wavelength (940 nm): The emission spectrum peaks at 940 nm, making the light invisible to the human eye while providing optimal sensitivity for common silicon photodetectors.
• High Radiant Intensity: Delivers exceptional power output (I_e), ensuring effective communication or detection over extended distances.
• Narrow Viewing Angle: Features a narrow beam half-angle, which concentrates the emitted energy for superior long-range performance and reduced light scatter.
• Standard T-1 ³/₄ Package: The 5 mm diameter package simplifies mounting and replacement in standard sockets and fixtures.
• Fast Switching Speed: Offers rapid rise and fall times, enabling its use in high-speed digital pulse applications, such as data transmission.

Technical Specifications:

• Peak Wavelength (λ_P): 940 nm
• Spectral Bandwidth (Δλ): ≈ 45 nm
• Forward Voltage (V_F): Typically 1.3 V @ I_F = 20 mA (≤ 1.5 V max)
• Continuous Forward Current (I_F): Maximum 100 mA
• Peak Forward Current (I_FP): Maximum 1 A (Pulse width ≤ 100 μs, 1% duty cycle)
• Radiant Intensity (I_e): Typically 60 mW/sr (Milliwatts per Steradian)
• Half Power Beam Angle (2θ_1/2): ≈ 20°

Mechanical Specifications:

• Package Type: T-1 ³/₄ (5 mm Through-Hole LED)
• Lens Color: Clear (Water Clear)
• Lead Polarity Indication: The longer lead designates the Anode (+); the shorter lead with a flat edge on the package indicates the Cathode (−).
• Storage Temperature Range: −40°C to +100°C

Dimensions:

• Package Diameter: ≈ 5.0 mm
• Overall Height: ≈ 8.7 mm
• Lead Pitch: ≈ 2.54 mm (Standard)

• Weight: ≈ 0.3 g (Extremely light)

Pinout and Wiring:

• Anode (+): The longer lead of the diode. Connect this to the positive side of your supply (V_CC), typically through a current-limiting resistor (R_limit).
• Cathode (−): The shorter lead of the diode, marked by a flat spot on the side of the plastic base. Connect this to the circuit ground (GND) or the switching element (e.g., transistor collector).
• Wiring Note: Always use an appropriate current-limiting resistor in series with the Anode to maintain the forward current (I_F) within the specified limits and prevent device failure.
