LM675: Thermal Resistance

Masakazu Adachi
Intellectual 2500 points
Part Number: LM675

Hello Team,

Can you tell me the Thermal Resistance (θJA, θJC, θJP) of LM675?

I would like to compare with other products.

Regards,

Masakazu

    Adachi-san,

    The LM675 datasheet in the Power Dissipation and Heat Sinking section on Pg. 8 mentions:

    θjA = 54°C/W for a TO-220 package (LM675)

    θjC = 2°C/W

    There is no mention of θjP in the datasheet so we do not have that information for that particular thermal resistance parameter.

    Figure 8, Device Dissipation vs Ambient Temperature, on datasheet Pg. 4 provides useful information about LM675 power dissipation vs. temperature for heatsinks having different thermal resistances.
