4. Example of series / TRISIL protection combination

For this example we will focus on US market applications where low series resistance is an issue. As men-

tioned earlier, TRISIL characteristics are the following:

. Minimum breakdown voltage

> 270V

. Maximum leakage current

< few µA

. Current capability

> 100A 10/1000µs

. Current capability

> 500A 2/10µs

The TRISIL which respects these requirements is the SMP100MC-270 from STMicroelectronics (see figure 5).
