What's the Most Common Semiconductor You Have Purchased in the Last 12 Months?

What's the Most Common Semiconductor You Have Purchased in the Last 12 Months?

Parents

  • Very cool question.. I had a look at a few months of orders, and for me, nearly every order has a microcontroller, and maybe voltage regulators, but whenever a diode or transistor is purchased then the quantity is much larger, e.g. 100 at a go, (since it doesn't make sense to buy a few of them at a high price), so in terms of overall quantity, it is probably diodes and discrete semi's (BJT and MOSFETs), but nearly every project includes microcontrollers and voltage regulators.

    I have not bought many LEDs only because I've already got a sufficient amount in a few popular SMD sizes, i.e. enough for prototyping. I have a "LED & optics" shoe-box full of packets of LEDs, the odd display, and optocouplers, etc).

    Interestingly though, I have zero blue LEDs (not normally an issue, but I was specifically looking for blue yesterday, since I wanted to test some blue laser-light blocking eyewear, and realized I have none : (

    So I looked at the blue LEDs on some existing product.. the blue completely disappears but they appear lit as faint yellow, through laser blocking specs, which was interesting!
