TL431: Request for Thermal Resistance

Renan Santos Adriano

Part Number: TL431

Hi Team,

My customer would like to know if we can provide the thermal resistance of TL431BQPK.

1) Thermal Resistance (Junction to case) (top) °C/W
2) Thermal resistance (Junction to ambient) °C/W
3) Thermal resistance (Junction to Case) (bottom) °C/W
4) Thermal resistance (Junction to board) °C/W

Can we also share the .tzr model for this part?

Looking forward to your response.

Regards,

Renan,

We provide the thermal resistance values for RθJA and for RθJC(top). These values for PK package are 52 °C/W and 9 °C/W respectively. If you need more thermal information, I can submit a request for more thermal modeling, but we don't share .trz models.

Thanks,

Abhinav.

Renan,

I submitted a request for thermal data for the TL431BQPK. The request might take a couple weeks so I can update you when we have the information.

Thanks,

Abhinav.
