Junction and Storage Temperature: +175�C DC Power Dissipation: @ +50�C Power Derating: / �C above +50�C Forward Voltage 200mA: 1.1 volts maximum ELECTRICAL CHARACTERISTICS @ 25�C

MAX. ZENER IMPEDANCE B-C-D SUFFIX ZZT @ 1ZT (NOTE 3) OHMS
MAXIMUM REVERSE LEAKAGE CURRENT lR (NOTE VR = VOLTS NON & ASUFFIX B-C-DSUFFIX

CASE: Hermetically sealed glass case. � 35 outline. LEAD MATERIAL: Copper clad steel. LEAD FINISH: Tin / Lead THERMAL RESISTANCE: (ROJEC): 250 �C/W maximum L =.375 inch THERMAL IMPEDANCE: (ZOJX): 35 �C/W maximum POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any.

No Suffix type numbers are +20% with guaranteed limits for only VZ, lR, and VF. Units with "A" suffix are +10% with guaranteed limits for VZ, lR, and VF. Units with guaranteed limits for all six parameters are indicated by a "B" suffix for +5.0% units, "C" suffix for +2.0% and "D" suffix for +1.0%. Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature + 3�C. Zener impedance is derived by superimposing A 60Hz rms a.c. current equal of 1ZT.

Reverse leakage currents are measured VR as shown on the table. �VZ is the maximum difference between VZ at lZT and VZ at lZL measured with the device junction in thermal equilibrium at the ambient temperature +25�C +3�C.
