Pressure sensor, MP3H6115A at high altitudes

We are using the MP3H6115A in a system that we have just tested to 40,000 feet.  We have had a failure (with no evidence of corona or arcing) which is traced to the same board as the pressure sensor.  The question is, how low in pressure can we do before the sensor self-destructs?    At 40,000 feet we are at 18.6 kPa, which is just barely in the range, but in testing, we might have dipped lower.
