PTH12030W: Nominal operating temperature without load

Steve Howell1

Part Number: PTH12030W


Hi all,

Could someone confirm that the PTH12030W operates ~85degC in ambient natural convection conditions when not subject to any load?

It would be nice to confirm this as I am new to this device and for a nominal temperature this high for an unloaded POL supply is new to me.

If this is the case, does this device need forced cooling?

Cheers.

Steve

    Hi Steve,

    Yes, the device can operate at 85°C ambient natural convection depending on your operating conditions. For a Vout = 5V, no. We would recommend implementing a forced cooling. For a Vout less than or equal to 3.3V, yes. It should operate just fine.Take a look at figures 4, 5 and 9 in the datasheet (pages 6 & 7) to see the safe operating area under different conditions.
    I would recommend taking a look at some of our other devices that might interest you for an application not requiring a Vout of 5V:
