I am Chintan Gopani. We have designed the Dimmer circuit using Triac BT136 and MOC3021 and Zero crossing detection circuit and other peripheral devices. Our application is to dim the standard dimmable LED lights fixtures in the USA.

Our application is based on the USA market. I attached the design file for the review.

I request you that please schedule the call with a technical person for the design improvement.

VCNL4040 vs VCNL4020

Hi,

I was looking for a whitepaper about a detailed comparison of Vishay's vcnl4040 and vcnl4020 sensors such as a comparison of power consumption for each feature, and key differences between these two sensors. I did it by reading their datasheet myself but you know to confirm I just wanted to see whether there is anything to compare.

Vishay's engineer team may have something about this issue.

Thank you!
