Abstract:

It is well known that heat is the enemy of electronic semiconductor devices because it causes high noise voltages and large leakage currents. But low temperatures can also present problems--for example, high junction voltages, loss of hermetic seals, and breaks in inputoutput lead wires. Today, electronic instrumentation and measurement equipment can be successfully operated in a winter field environment much more readily than 10 or even 5 years ago. Semiconductor devices like transistors, diodes, silicon control rectifiers SCRs, and operational amplifiers will work at temperatures down to -40 C. With modern integrated circuit technology it is much easier to obtain excellent thermal performance from a circuit since the entire circuit is concentrated on a small chip, guaranteeing that all its components will have a uniform temperature. Better design strategies are constantly being developed to keep electronic devices well behaved over wide temperature ranges.
