The **LSRG3393-R6-PF** is an optoelectronic component, specifically a **T-1 (3mm) Round Subminiature LED**. This part is commonly used in indicator panels, consumer electronics, and industrial displays where high brightness and reliability are required. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. General Specifications The part number indicates a specific color profile and package type. This LED is typically a **Green** or **Super Red/Green** variant (depending on the specific manufacturer batch codes), but most commonly refers to a high-efficiency green LED. | Feature | Specification | | :--- | :--- | | **Package Type** | T-1 (3mm) Round | | **Lens Appearance** | Water Clear or Color Diffused (Part-specific) | | **Material** | GaP (Gallium Phosphide) or AlGaInP | | **Mounting Type** | Through-Hole | | **Lead Finish** | Pb-Free (Lead-Free / RoHS Compliant) | --- ### 2. Absolute Maximum Ratings ($T_a = 25^\circ C$) Exceeding these values can lead to permanent damage or reduced lifespan of the component. | Parameter | Symbol | Maximum Rating | Unit | | :--- | :--- | :--- | :--- | | Power Dissipation | $P_d$ | 65 - 75 | mW | | Peak Forward Current | $I_{FP}$ | 100 | mA | | Continuous Forward Current | $I_F$ | 25 - 30 | mA | | Reverse Voltage | $V_R$ | 5 | V | | Operating Temperature | $T_{opr}$ | -40 to +85 | $^\circ C$ | --- ### 3. Electro-Optical Characteristics These values define how the LED performs under standard operating conditions (usually $I_F = 20mA$). | Parameter | Symbol | Min | Typ | Max | Unit | | :--- | :--- | :--- | :--- | :--- | :--- | | **Forward Voltage** | $V_F$ | 1.8 | 2.1 | 2.6 | V | | **Luminous Intensity** | $I_v$ | 20 | 50 | - | mcd | | **Peak Wavelength** | $\lambda_p$ | - | 565 - 570 | - | nm | | **Viewing Angle** | $2\theta_{1/2}$ | - | 30 - 60 | - | deg | --- ### 4. Application Considerations * **Current Limiting:** Always use a series resistor to prevent the LED from burning out. The resistor value can be calculated using: `R = (V_source - V_forward) / I_forward` * **Polarity:** As a diode, it is polarity-sensitive. The longer lead is typically the **Anode (+)** and the shorter lead (or the side with the flat edge on the casing) is the **Cathode (-)**. * **Soldering:** Avoid prolonged exposure to high heat. Standard wave soldering or manual soldering at $260^\circ C$ for less than 5 seconds is recommended. ---
