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

: [ P_total = V_ce(sat) \cdot I_c \cdot D + f_sw \cdot (E_on + E_off) ] where D = duty cycle. 3.3 Thermal Cycling Capability Power cycling (ΔTj) and thermal cycling (ΔTc) limits are provided via lifetime curves (Coffin-Manson type). Example (typical values): Fuji Igbt Modules Application Manual

: 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: [ T_j = T_case + P_loss \cdot R_th(j-c)
