Is there any transient heat resistance data for repeated pulse operation of the 2SK3483?
Sorry, we do not have any transient heat resistance data for repeated pulse operation of the 2SK3483. To calculate the channel temperature during repeated pulse operation, use formula 1 in section (6) Repetition frequency Tch(peak), thermal resistance θch-c(PW/T), 2.3.5 Heat Radiation Design on page 29 of the Power MOSFET Application Note. θch-c and θch-c(PW) in formula 1 are the same as Rth(ch-c) and rth(ch-c) mentioned elsewhere in the datasheet, respectively.
