VF Forward Voltage = 1.2 V Maxim um @ IF = 200 mA for all types
Notes:
1. The type numbers listed have zener voltage min/max limits as shown and have a standard tolerance on the nominal zener
voltage of 5%.
2. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter
voltage tol erances, contact your nearest Synsemi repres ent ati ve.
3. The zener im pedanc e is derived fr om t he 60-cycl e ac volt age, which res ult s when an ac current havin g an rm s value equal t o
10% of the dc zener current (IZT or IZK) is superimposed to IZT or IZK.

composed of pol yeste r film, adhesi ve la yer,
sealant, and anti-static sprayed agent.
These reeled parts in standard option are
shipped with 2,500 units per 7” or 178cm
diameter reel. The reels are blue in colo
r
and made of recyclable plastic. Othe
r
option comes in 10,000 units per 13” o
r
330cm diameter reel
