I'm using MRFE6VP61K25HR5. But I come across some problems because I just set foot in this area.
1、If the thermal resistance Rθjc=0.15℃/W obtained in this way:（225℃-25℃）/1333 W=0.15℃/W?If so,it shows that the RF Power LDMOS Transistors have a good heat sink so that its junction temperature is maintained at 25℃ ?And then what's the thermal resistance between junction and environment without heat sink?The datasheet does not seem to be given.
2、How the data 6.67W/℃ obtained in the datasheet?
3、In the table 2,what does "Zθjc=0.03℃/W" mean?And how it obtained?
4、Why the datasheet have not support the thermal impedance curve of RF Power LDMOS Transistors?
5、What is the difference between MRFE6VP61K25HR5 and MRFE6VP61K25HR6?
hope some help.
