In the Sleep mode and nrf52810 was Broadcasting with space 125ms once.
The normal temperature was good,that only 0.08mA. but why not 85℃,The current was up to 0.21 mA ,it's no oher action.
How can i solve it?This is chip P-n junction issue?

Hi,
The behavior you are seeing is normal and expected. The leakage current will increase as temperature increase, and decrease with lower temperature. The total current consumption will therefore increase with increasing temperature.
I don't think so, on PCBA that the chip only nrf52810. In the Spec, in 85℃,The file nRF52810_PS_v1.3 and 5.2.1.2 Radio transmitting/receiving section ,it's in the 85℃ and 3.3V power,it's decrease.See below photo.
Hi,
That is for the RADIO itself only. The System ON idle, and System OFF mode sleep currents will be higher with increasing temperature.See the plots at the end of this page: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52810%2F_tmp%2Fgluon%2Fautodita%2FCURRENT%2Fparameters.id_current_sleep.html
