Ah, the 'Figaro' sensor.

I think we're currently on the threshold of a number of types of discrete semiconductors going extinct.

I've noticed that low voltage dual gate mosfets have gone. A few 12v ones are lingering. The range of varactor diodes is shrinking rapidly. Avago (now Broadcom) have axed a lot of their MMIC parts saying turnover was too low.

Companies guard commercially-sensitive data such as sales figures like the crown jewels. But if they are ditching everything below some magic (and also secret) figure, how do I as a designer know if anything is safe to put in my next design?
