PHOTODIODE Si photodiode S1226-18BU, S1336-18BU For high power UV monitor, and UV to visible, precision photometry S1226-18BU and S1336-18BU are Si photodiodes encapsulated in a TO-18 package with a UV glass window. These photodiodes have high sensitivity from the UV to near infrared range and operate reliably when detecting high power UV radiation (such as from mercury lamps). Features Applications l TO-18 package with UV glass window l High sensitivity from the UV to near infrared range l High reliability versus high power UV radiation l Mercury lamp (λ=254 nm) monitor l Excimer laser (KrF: λ=248 nm) monitor l Other UV detection ■ General ratings / Absolute maximum ratings Type No. S1226-18BU S1336-18BU Window material UV glass Package TO-18 Active area size Effective active area (mm) (mm2) 1.1 × 1.1 1.2 Absolute maximum ratings Reverse Operating Storage voltage temperature temperature VR Max.
