Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
1.FR−5 = 3.5 X 1.5 inches, using the minimum recommended footprint.
2.Thermal Resistance measurement obtained via infrared Scan Method.
See specific marking information in the device marking column of the Electrical Characteristics table on page 3 of this data sheet.

3.The type numbers shown have a standard tolerance of ±5% on the nominal Zener voltage.
4.Nominal Zener voltage is measured with the device junction in thermal equilibrium at T L = 30°C $1°C.
5.Z ZT and Z ZK are measured by dividing the AC voltage drop across the device by the ac current applied.
The specified limits are for I Z(AC) = 0.1 I Z(dc) with the AC frequency = 1 KHz.
*The “G’’ suffix indicates Pb−Free package available.
