OPA2333: OPA2333

Part Number: OPA2333

Hi,

I have found the peak solder temperature is 260C. Is this the maximum temperature the component can sustain? For how long?

Thank you,

Francesco

    The absolute maximum ratings limit the temperature to 150 °C. Soldering is done only once, for a short time, according to the IPC/JEDEC J-STD-020 standard.

    Hi Francesco,

    Here is a document on recommended solder profiles: https://www.ti.com/lit/an/snoa292j/snoa292j.pdf 

    The table specifies a maximum solder temperature of 260°C and a recommended dwell time of 3 seconds.

    As Clemens pointed out, the solder profile is much different than the maximum operating temperature and maximum storage temperature of the device. See from the absolute maximum ratings table in the datasheet, the storage temperature should be less than 150°C, and the operating junction temperature must be less than 150°C.

    Regards,

    Zach

    Hi Clemens and Zach,

    Thank you for your replies, they indeed resolve very well my doubts about the product. I have just a technical curiosity if you have evaluated that and you can disclose it: what is the limiting factor at 150C? Like the encapsulating material or some other materials, or there are some electronic alteration if kept at high temperature?

    Kind regards,

    Francesco

    Hi Francesco,

    The maximum junction temperature is limited to prevent the device from going into thermal runaway.

    Hi again Zach!

    Sorry a further question: in case it is not operating, shouldn't high temperatures be less problematic because the device can't go into thermal runaway?

    Thank you,

    Francesco

    Hi Francesco,

    Exposing the devices to high temperatures can severely accelerate the aging of the device, and reduce the device's lifespan. This effect can be exponential at extreme temperatures, which is why the storage temperature is given an absolute maximum rating at 150­°C.

    You are correct that the storage temperature is relaxed compared to the operating temperature, but only at the low temperature range.

    Zach

    Hi Zach,

    Perfect, thank you for the explanation, it is much more clear now!

    Kind regards,
