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 ...
Voltage clamps for protecting low-voltage dc circuits require a new approach to circuit design. Many commonly used voltage clamps were built for systems of 5 V or higher, but lower-voltage systems ...
Diodes Incorporated has announced the introduction of an overvoltage clamp for the protection of power management ICs (PMIC) in portable applications. Provided in the small form factor 1.1mm x 1.4mm x ...
