Born around the year 2000 they already are at the second or the third generation and still represent the highest efficiency. The miniaturization of the systems is a trend followed in all the electronics systems and particularly in the portables ones. In many of them the dimension and the weight of the power supplies are a dominant parameter of the whole system and more and more switching power supplies manufacturers (SMPS – switching mode power supply) define the road-map to increase the density power of their devices.

PCB Design Guidelines that Maximize the Performance of TVS Diodes

Transient Voltage Suppressors (TVS) avalanche diodes and diode arrays can be used to protect sensitive electronic components from the surge pulses that arise from ESD and EMI. The small size, fast response time, low clamping voltage and low cost of TVS diodes provides for an effective solution to prevent surge problems. Avalanche TVS diodes and diode arrays are relatively simple devices to use to suppress surge voltages. Only a few PCB design rules must be followed to optimize the ESD and EMI immunity level of the protection circuits.

Designers Maximize TVS Diode Performance

A transient voltage suppressor (TVS) diode is an effective, low-cost option to protect sensitive electronic components from electrostatic discharge (ESD) and electromagnetic interference (EMI) surge pulses. However, to maximize the
surge immunity provided by a TVS diode, designers should follow certain printed circuit board (PCB) layout guidelines. Layout examples help illustrate the tradeoffs between the different circuit confi gurations available with TVS diodes.
