SiC Schottky Blocking Diode for BepiColombo Solar Array

Project: SiC Schottky Blocking Diode for BepiColombo Solar Array 

Customer: ESA (European Space Agency)

Alter TEchnology as reference test house 

• -Screening of a high number of devices under very harsh conditions: Custom testing setup
• -High Temperature: 270ºC
• -Low temp: -170ºC
• -High Voltage tests: 250V
• -High Power tests: 2.5A

Long lasting tests with constant monitoring of electrical parameters and temperature of each single diode.

500h monitoring of reverse biased diodes

Radiation testing of the devices 

CONCLUSION

• -Gamma Radiation

• -Protons Radiation

• Heavy Ions Radiation
  • (sensitivity recently discovered)

More ongoing radiation campaigns to understand the device degradation under heavy ions radiation.
