4H-SiC visible blind avalanche photodiode (APD) linear arrays have been fabricated and successfully tested. A 40 pixel linear array with only one bad pixel has been demonstrated. The linear arrays show uniform breakdown voltage and low leakage current. The photoresponse and the excess noise factor of 4H-SiC APD pixels have been studied. A very high multiplication gain with very low excess noise factors is reported.
