TVS Diodes

Oh man. Today I recorded a whole Mail Call video for the channel and at the end realized the microphone was off the whole time! Boo. Anyway. I was going to put some notes about my TVS diodes in the show notes, but as there is no longer going to be a show, I’m just making some notes here.

The TVS diodes I have I got here: DIP SMD Zener Diode Fast Switching Schottky TVS Diode Assorted Kit 1N4007 1N5408 FR207 1N5819 1N5822 1N4148 10A10 M7 SS14 2V-47V.

Particularly I ordered 210Pcs One way and 210Pcs Two way. I have stored both types in the same component drawer, by their ratings. The one-way devices have a polarity band and use the ‘A’ suffix on the component code; the two-way devices have no polarity band and use the ‘CA’ suffix.
