FAQ: What are high temperature electronics?

   

What are high temperature electronics?

Frequently Asked Questions

High and low temperatures are relative terms. For electronics, traditional silicon-based devices are generally limited to temperatures below 125°C for reliable operation. High temperature electronics may then be considered to be electronic devices and packaging in which operating temperatures are beyond this standard temperature. Currently, the term high temperature often refers to requirements in the range 200-400°C.

See the table below for a relative comparison of semiconductor technology temperature tolerances. High temperature applications can be found in 'Where are high temperature electronics used?'

Material Tech maturity Temp tolerance (°C)
Silicon (Si) Very high 125-250
Silicon-on-Insulator (SOI) Medium 250-300
Gallium Arsenide (GaAs) High 350
Gallium Nitride (GaN) Very low >500
Silicon Carbide (SiC) Low >750
Diamond Very low >800
