2.8 Optional External Protection Circuitry

The XTR200EVM comes with optional protection circuitry for the output of the device. Included is space for both a TVS diode (D1) and a snubber network (R4 and R6).

The values of R4 and R6 were arbitrarily chosen in the schematic. The recommended component values depend on the system requirements. To learn more about how to select the snubber network component values, see the Power Tips: Calculate an R-C Snubber in Seven Steps technical article.

D1 was also arbitrarily chosen and is shown as a unidirectional TVS diode in this example, but a bidirectional TVS diode can be used, as well. The best TVS diode option depends on the system requirements. To learn more about how to select the correct TVS diode, see the How to select a Surge Diode application note.
