Part Number: TL4050A

Hi Team,

For power dissipation calculation purposes, what is the thermal impedance (θJA) for the DBZ package of TL4050A?


Thanks in advance!


Kind Regards,

Jejomar

    Hi Jejomar,

    Use the values below.

    θJA Junction-to-ambient thermal resistance(2) 331.1 C/W
    θJCtop Junction-to-case (top) thermal resistance(3) 107.5 C/W
    θJB Junction-to-board thermal resistance(4) 63.4 C/W
    ψJT Junction-to-top characterization parameter(5) 4.9 C/W
    ψJB Junction-to-board characterization parameter(6) 61.7 C/W
