Industrial vs Commercial components

[shaiko]

what is the difference between Industrial and Commercial IC's ?
I.E - what allows Industrial IC's to withstand wider temperature ranges ?
Is it the packaging material ? Is it the actual die ?

You mean difference between industrial and military ?

Commercial are all. :smile:

Temperature ranges:
Commercial grade: 0 °C to 70 °C (sometimes −10 °C to 70 °C)
Industrial grade: −40 °C to 85 °C (sometimes −25 °C to 85 °C)
Military grade: −55 °C to 125 °C (sometimes -65 °C to 175 °C)

Commercial DIPs are usually in plastic package military use ceramic, and there is different manufacturing cost. Inside connections to die pads can be different too to accommodate larger temperature range by using materials with different coefficients of expansion. Testing each part is more rigorous.

Because some devices generate heat during operation, they may require thermal management to ensure they are within their specified operating temperature range, specifically, that they are operating at or below the maximum operating temperature of the device. Cooling a microprocessor mounted in a typical commercial or retail configuration requires "a heatsink properly mounted to the processor, and effective airflow through the system chassis". Systems are designed to protect the processor from unusual operating conditions, such as "higher than normal ambient air temperatures or failure of a system thermal management component (such as a system fan)", though in "a properly designed system, this feature should never become active". Cooling and other thermal management techniques may affect performance and noise level. Noise mitigation strategies may be required in residential applications to ensure that the noise level does not become uncomfortable.

Here is one old thread maybe its good to look:
