DESIGN DATA
CASE: Hermetically sealed glass case. DO 35 outline. LEAD MATERIAL: Copper clad steel. LEAD FINISH: Tin / Lead THERMAL RESISTANCE: (ROJEC): 250 °C/W maximum at L = .375 inch THERMAL IMPEDANCE: (ZOJX): 35 °C/W maximum POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any.
NOTE 1
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 of 25°C + 3°C. Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT.
NOTE 2 NOTE 3 NOTE 4 NOTE 5
Reverse leakage currents are measured at VR as shown on the table. ³VZ is the maximum difference between VZ at lZT and VZ at lZL measured with the device junction in thermal equilibrium at the ambient temperature of +25°C +3°C.
