LM4040-N: Stability and Lifetime

Part Number: LM4040-N
Other Parts Discussed in Thread: LM4040,


We are looking at the 5V reference LM4040 and had a few questions.

  • What is the difference in LM4040 and LM4040-N?
  • Is the LM4040AIM3X-5.0/NOPB the orderable LM4040-N P/N for the 5V reference in the small DBZ package?
  • If clamped constantly, will there be any stability or lifetime issues?
  • If constantly reversed at 2-4.5V for the 5V Zener, does this affect the stability of lifetime of the diode?

Thank you,
