High-Current Power TVS Diodes - PTVSxx Series

Bourns' power TVS diodes provide effective electrostatic discharge (ESD) and lightning protection in applications needing high-power DC bus protection. With the capability to handle surge current from 1 kA up to 20 kA at low voltages, the PTVS diodes meet some of the industry's key safety ratings like IEC610000-4-2 Level 4 for ESD protection and IEC61000-4-5 lighting protection.

Power supplies, both AC and DC, used in telecommunications and other exposed applications often need protection from hostile events such as power line surges and indirect lightning strikes. It is critical to avoid damage to the power supply by limiting the peak surge voltage to an acceptable level without short-circuiting the line for an extended period of time in order to minimize the downtime of critical systems and avoid costly maintenance calls. Power TVS diodes fulfill the requirements of these applications.
