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 ...

External TVS diodes can be used to supplement the internal clamping diodes of ICs. Surge ability of silicon TVS diodes are related to size. External TVS diodes can be 10x larger than internal clamping ...

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 ...

In the quest for higher speed and lower costs, today’s modern electronics use increasingly dense integrated circuit technologies, whose sensitivity to surges creates difficult challenges for designers ...

A variety of over-current and overvoltage products are on the market for protecting VDSL telecommunications circuits. These include transformer line-side capacitors, transformer driver-side diodes, ...

Designing automotive electronics presents numerous technical challenges, including the need to protect against electrical hazards under the hood and in the cabin. The three major sources of electrical ...
