[ T_j = T_case + P_loss \cdot R_th(j-c) ] [ T_case = T_ambient + P_loss \cdot R_th(c-a) ]

[ V_CE peak = V_DC + L_\sigma \cdot \fracdidt ]

: Gate voltage below +13 V increases Vce(sat) and conduction loss. Above +20 V risks gate oxide breakdown. 2.2 Snubber Circuits Stray inductance (Lσ) in the commutation loop causes voltage overshoot during turn-off:
