An SCR has \({V_{DRM}} = 600\;V,\;{\left( {\frac{{dv}}{{dt}}} \right)_{max}} = 25\frac{V}{{\mu s}},\;and\;{\left( {\frac{{di}}{{dt}}} \right)_{max}} = 30\;A/\mu s\). It is used to energize a 100 Ω resistance load. What are the minimum values for an RC snubber circuit to avoid unintentional triggering? (VDRM means peak repetitive forward blocking voltage)

• A. T = 10 μs, C = 2.4 μF and R = 4.5 mΩ
• B. T = 24 μs, C = 0.24 μF and R = 0.833 Ω
• C. T = 24 μs, C = 2.4 μF and R = 7.0 mΩ
• D. T = 10 μs, C = 0.24 μF and R = 7.0 mΩ
