Electrical Specifications @ +25 ºC (Unless Otherwise Specified)
NOTE 1: The JEDEC type numbers shown (B Suffix) have a +5% tolerence on nominal Zener Votlage. The suffix A is used to identify +10%
tolerance; suffix C is used to identify +
2%: and suffix D is used identify +1%; no suffix indicates +20%.
