3: The reverse surge current is measured at 25
1: The JEDEC type number shown with an A suffix have a 5% tolerance on nominal zener voltage. No
4: Voltage measurements tobe performed 90 seconds after application of DC current.
5: RoHs Compliant already and Pb-free sticker on reel , box & carton indicated RoHs compliant .
2: The Zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an
suffix signifies a 10% tolerance, C signifies 2%.
