SMJ320C40: Thermal Properties Difference Between SMJ320C40 and SM320C40 ?

Part Number: SMJ320C40
Other Parts Discussed in Thread: SM320C40


I was told to reach out to an Applications Engineer in this forum for this question. I was wondering if there was a difference in thermal properties between the SMJ320C40 and SM320C40 ('SMJ' versus 'SM')? Specifically, any difference between SMJ320C40GFS60 and SM320C40GFS60?

The differences I found were that the 'SMJ' designates the MIL-PRF-38535 standard, and the 'SM' designates the standard processing. They seem to have the same operating temperature range (-55 C to 100 C), and the same packge type, but have different Processing Levels (QML for 'SMJ', Standard for 'SM'). I was wondering if there were any changes in their thermal properties too? Are there any other noteable differences between the two difference devices ('SMJ' versus 'SM')?

Any help is much appreciated! Thanks again!

  • Colby,

    From a thermal standpoint the two devices are identical.  They really only differ in processing and testing.

    They are in same package and will have same thermal characteristics.
