Hi all,
I have requirement for a display PCBA, It has some 7-seg LEDs display (used for home appliance).
I met a problem: after a certain time, one or several segments were broken and no light. (error rate about 0.5%)
To solve this trouble, our supplier (an IDH) who designed my PCBA said he must design the new 7-seg LED with integrated Zener diode to avoid damage by EM environment.
To integrated zener, he have to use a custom led by open a new mold for LED.
I tried to find some led built-in zener on internet, no many LED use this solution. So, do you think he said correct or not ?
Thanks.
