===== MOSFET =====
**Question:**\\
Two conditions are described for the total dissipation parameter in the power ratings of a power transistor or a power MOS FET: **Ta** = 25°C and **Tc** = 25°C. What is the difference between these conditions?

**Answer:**\\
The specification at **Ta** = 25°C in the power ratings refers to the total power dissipation of a discrete semiconductor element in an environment with an ambient temperature of 25°C.
In this case, the thermal resistance from the heat source to the ambient air is expressed as **Rth(j-a)**.

The specification at **Tc** = 25°C in the power ratings refers to the total power dissipation when the semiconductor element (case) itself has been forcibly cooled, i.e., when temperature of the package surface is kept at 25°C.
Note that the ratings may include the note "with infinite heat sink". However, in actual use, it is very difficult to make the package surface temperature exactly 25°C, and if you also take derating into account, the allowable power will in fact be somewhere in between **Ta** = 25°C and **Tc** = 25°C.

**Ta** = Ambient temperature. This is a still air temperature reading for the environment that the semiconductor is in.

**Tc** = Case temperature. This is the temperature reading of the case of the semiconductor device.

>**Ta** would normally mean the environment is cooled and kept at 25°C whereas Tc would mean the device is forcibly cooled through a directly attached heatsink and cooled to the 25°C.

**Tj** = Operating Junction temperature. This is the temperature of the device circuit itself under given conditions. **Tj** must be calculated from the **Tc** and/or **Ta**.

**TJmax** = Maximum Junction temperature. This is the maximum temperature that the device tolerate.

=== Для 1.8В ===
BSS138, FDV301N, WM02N20G (большая ёмкость), WM02N08G (получше, но большая ёмкость)

FDV301N лучше BSS138

FDV303N хороший, ёмкость больше, чем FDV301N
