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 ...
Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...
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 ...
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, ...
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 ...
