App note: Design considerations for a harsh industrial environment

Saturday, March 9th, 2019

This article discusses factors that influence the robustness of a circuit in a harsh environment, like you would find for industrial applications. The topics covered include ways to handle voltage transients and to protect against electrostatic discharge (ESD) and faults. Link here Semiconductor (IC) robustness—what is the operating temperature range? How...

App note: Ambiguity of the peak power rating of TVS devices

Sunday, August 24th, 2014

Here's a tip app note (PDF) from ON Semiconductor on selecting specs for an TVS diode. There are two important properties of a TVS device during an electrical stress. The TVS must be able to self-protect and survive the stress current, and the TVS must clamp the protected line to...

App note: What is a silicon transient voltage suppressor and how does it work

Sunday, August 3rd, 2014

A primer app note(PDF) on silicon transient voltage suppressors by Microsemi. Silicon transient voltage suppressors (TVSs) are clamping devices that limit voltage spikes by low impedance avalanche breakdown of a rugged silicon pn jucntion. They are used to protect sensitive components from electrical overstress such as that caused by induced...

  • William: lol I'm happy to waste 3c for each program/debug cycle... but probably not the time spent soldering a new device down to a proto board!...
