STRVS parameters

This section defines the electrical and thermal characteristics of the STRVS.

1.1

Electrical parameters

Figure 1 shows the typical reverse characteristic given at two temperatures of an STRVS

device.

the device is still acting as an open circuit. This parameter is one of the key parameters in

circuit protection.

The breakdown voltage corresponds to the voltage from which the STRVS starts to go into

parameter follows a linear variation with junction temperature as shown in Equation 1.

T = temperature coefficient in 1/°C.
