Bourns has introduced a bidirectional power transient voltage suppressor (PTVS) diode designed specifically for high power DC line protection applications. The new model PTVS20-015C-TH is capable of handling a 20 kA surge at a low voltage of 15 V, making it an ideal and effective electrostatic discharge (ESD) protection solution for applications requiring high power DC bus protection.


     Bourns Model PTVS20-015C-TH PTVS diode meets IEC 61000-4-2 Level 4 ESD protection requirements. It also has a low clamping voltage at peak pulse current, helping to meet the electrical surge requirements of IEC 61000-4-5 8/20 μs lightning protection.


     To support high currents such as 60 kA in next-generation applications, designers often have to connect many devices with low current processing capabilities in parallel. With a single device capable of handling 20 kA, a smaller number of devices can now be paralleled to achieve the same level of protection required. This reduces the total BOM number and helps save valuable space on the PCB.
