Expensive semiconductor laser diodes have no tolerance for fast voltage or current transients. To minimize the risk of damage, a standard JFET-clamp circuit shorts the laser when there is no supply ...

A circuit powered from an automotive electrical system must survive in a harsh environment. Voltage transients can be either random or repetitive. Repetitive transients, such as a cranking the engine, ...

A diode makes 12V car electronics safer and simpler. It cuts extra parts, reduces power loss, and keeps important systems ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

There are limitations to older circuit protection solutions that use Transient Voltage Suppressor (TVS) diodes. Responding to this situation, completely new transient current suppressors utilize ...

Some amplifier applications require clamping or limiting due to large, sporadic signals appearing at the amplifier input. Clamping these errant signals protects the amplifier and other sensitive ...

[Afroman] is back again with another great tutorial video on the basics of electronics. This time it’s zener diodes. Page three or four of every ‘beginners guide to electronics’ covers a diode as, “a ...
