Type Number DC Power Dissipation at TL=75oC, measure at Zero Lead Length Derate above 75 oC Thermal Resistance from Junction-to-Lead Symbol PD RJL Value 3.0 40 25 -65 to + 150 Units Watts mW/ oC o C/W o C Operating and Storage Temperature Range TJ, TSTG 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 attached.

Tolerance and type number designation the type numbers listed indicate a tolerance of 5%. 2. Zener voltage (VZ) measurement Nominal Zener voltage is measured with the device junction in thermal equilibrium o with ambient temperature at 25 C. 3. Zener impedance (ZZ) derivation: ZZT and ZZK are measured by dividing the ac voltage drop across the device by the ac current applied. The specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz.
