5050 RGB LED SMD RGB with Zener Diode

5050 RGB LED SMT with Zener Diode Protection

Compare with Red SMD LED Chip, Green Smd LED and Blue SMD LED chip will be easier to get hurt by static electricity. From the pciture we can see there have five chips inside of the 5050 SMD LED package. The red little one is the red chip, the little square white one is green chip and the rectangle white one is blue chip. But there still have other two black chip that  looks like two little black dots. Which is Zener diode. We weld this zener diode in front of green and blue chip so that the diode can protect these chip from static electricity(or high voltage). This 5050 SMD RGB LED have 6 pins to connect each color(red, green and blue) to the circuit. When people use this RGB LED, they can control the color by control the current to the pins.

Product Detail:

We produce this LED with 5050 SMD LED red copper LED frame as holder and package, 99.99% pure gold wire for inside circuit conntection, high quality stable chip for lighting inside and high refractive index epoxy to cover in surface. For this RGB LED, we also adding 2 zener diodes inside the circuit to protect the LED chip from high voltage and static electricity;

Main Application:

LED Backlight, Indicator light, LED toy, LED flexibel strip;

HANDLING PRECAUTIONS:

Compare to epoxy encapsulant that is hard and brittle, silicone is softer and flexible Althouth its characteristiec significantly reduces thermal stress, it is more susceptible to damage by extemal mechanical force. As a result, special handling precautions need to be observed during assembly using silicone encapsulated Led products. Failure to comply might lead to damage and premature failure of the led

1. Handle the component along the side surfaces by using forceps or appropriate tools.

2, Do not directly touch or handle the silicone lens surface. It may damage the internal circuitry.

3, Do not stack together assembled PCBS containing exposed LEDs. Impact may scratch the silicone lens or damage the internal circuitry.

4, 4-A The inner diameter of the SMD pickup nozzle should not exceed the size of the LED to prevent air leaks;

    4-B A plible material is suggested for the nozzle tip to avoid acratching or damaging the LED surface during pickup.

    4-C The dimension of the component must be accurately programmed in the pick-and-place machine to insure precise pickup and avoid damage during production;

    4-D As silicone encapsulation is permeable to gases, some corrosive substances such as H2S might corrode silver plationg of leadframe. Special care should be taken if an LED with silicone encapsulation is to used near such substances. 

5, Please aviod continued exposure to the condensing moisture environment and keep the product away from repid transitions in ambiemt temperature.

6, Product in the original sealed package is recommended to be assembled within 24 hours of opening.
