Bi-directional PTVS diode is high current model in SM DFN package
The PTVS20-015C-H PTVS diode features 20kA, eight/20mµs surge handling capability with a low clamping voltage of 15V.

Packaged in a compact, surface mount DFN package, the 
PTVS diode delivers electrostatic discharge (ESD) protection for high power DC line protection. The  diode meets IEC 61000-4-2 Level 4 ESD protection requirements. It also features low clamping voltage at peak pulse current and assists in meeting IEC 61000-4-5 current surge requirements for lightning protection.

In order to support large currents, e.g. 60kA, designers typically have had to connect many devices with low current handling capability in parallel, but using this single device capable of handling 20kA, means fewer devices can be connected in parallel to achieve the same desired protection level. In addition to reducing the total bill of materials while saving PCB space.

The Bourns Model PTVS20-015C-H is available now and is RoHS-compliant and halogen-free.
