It includes: Lens Size (5mm), Lens Type (Clear/Transparent, Diffused/Matte, Color), Color (White, Red, Green, Yellow-Green, Blue, Yellow, Orange, UV, Pink, Warm White), Luminous Intensity (ranging from 300-18000mcd), Forward Voltage (2V-3.2V), Forward Current (20mA), and Viewing Angle (30°).

Figure 4: LED Dimensions. This diagram provides precise measurements for the 5mm LED diode, including lens diameter (5.0mm/0.197inch), overall height (7.7mm/0.303inch), lead length (18.5mm/0.728inch), and lead spacing (2.54mm/0.100inch). Tolerance is ±5%.

5. Setup and Installation

5.1. Storage Conditions

• Temperature: 10°C - 26°C
• Humidity: 40% - 65%
• Store in sealed packaging to prevent lead oxidation.

5.2. Handling Precautions (ESD Protection)

To prevent electrostatic discharge (ESD) damage, follow these guidelines:

• Wear gloves or finger cots when inspecting or handling LEDs.
• Ensure your workbench is grounded.
• Reseal packaging immediately after opening.
• Before production, verify all equipment grounding wires are functioning properly.
• Check that personnel wrist straps are functioning and securely connected to bare skin.
• Operators should wear anti-static gloves or finger cots during insertion.
• Work surfaces must be covered with grounded anti-static mats, with all mats interconnected to ground.
• Use opened components within 24 hours to prevent oxidation/rust on leads.

5.3. Lead Forming

• Maintain a minimum 3 mm distance from the bend point to the bottom of the epoxy body.
• Do not bend leads during or after soldering.
• If lead forming is necessary, it must be done before soldering.

6. Operating Instructions

6.1. Soldering Methods for Two-pin LEDs

Four common soldering methods are applicable:

• Manual Soldering: Set soldering iron temperature to approximately 315°C. Soldering time should not exceed 5 seconds (preferably within 3 seconds). Do not exceed three soldering cycles. Temperature settings depend on solder wire composition and are not fixed.
• Automatic Spot Soldering: Follow standard procedures. Temperature set according to solder composition. Duration: 3 seconds.
• Dip Soldering: Verify solder pot temperature before use—maximum 235°C ± 5°C. Dipping time not to exceed 5 seconds. Monitor solder temperature, select appropriate flux, and keep solder surface clean.
• Wave Soldering: Flux selection is critical; different flux types affect joint finish quality. Preheat time affects solder quality. Monitor solder level regularly, replace solder periodically. Adjust temperature according to solder bar composition, but maximum should not exceed 260°C ± 5°C, and dwell time should not exceed 5 seconds.

6.2. General Soldering Notes

• For all soldering methods: Equipment must be grounded, equipment static voltage not to exceed 30 V, and personnel static voltage not to exceed 50 V.
• Constant-temperature soldering irons are recommended for manual soldering.
• In cold, dry environments, minimize personnel movement to prevent static generation.

6.3. Operating Notes

• LED service life decreases along a curve with increasing current and temperature.
• Reverse leakage current increases significantly with temperature, accelerating LED degradation.

6.4. Circuit Design

• Ground circuit is recommended in PCB design.

6.5. Critical Operating Environment

• Maintain humidity between 50% and 80%; otherwise, there is a risk of electrostatic discharge damage or overcurrent failure.
• Operating temperature range: -20°C to 70°C.

6.6. Special Notes for White LEDs

• Do not mix different grade/bin white LEDs, especially different color coordinates.
• Do not connect in series LEDs with different forward voltage ratings.
• Constant current drive is recommended.

7. Maintenance

LEDs are generally maintenance-free once installed. Proper storage and handling as described in Section 5.1 and 5.2 will ensure their longevity and performance before installation. Keep LEDs clean and free from dust or moisture.

8. Troubleshooting

LED Not Lighting Up:

• Check Polarity: LEDs are diodes and are polarity-sensitive. Ensure the anode (longer lead) is connected to the positive voltage and the cathode (shorter lead, flat edge on the lens) to the negative/ground.
• Verify Voltage/Current: Ensure the applied voltage and current are within the specified operating range (2V-3.2V, 20mA). Exceeding these can damage the LED, while insufficient power will prevent it from lighting.
• Inspect Connections: Check for any loose or faulty solder joints or wiring.
• Test LED: If possible, test the LED with a known good power source and current-limiting resistor to rule out a defective component.

9. Applications

CHANZON 5mm LED Diodes are widely used in various fields due to their versatility and efficiency.

10. User Tips

• Always double-check the LED size (5mm in this case) and color against your project requirements before soldering.
• Confirm the forward voltage and current for each specific LED color you are using, as these can vary slightly.
• Use appropriate current-limiting resistors to protect your LEDs from overcurrent, which can significantly shorten their lifespan.
