DESIGN DATA
CASE:
DO-213AA, Hermetically sealed
glass case. (MELF, SOD-80, LL34)
LEAD FINISH:
Tin / Lead
THERMAL RESISTANCE: (R
OJEC):
100 擄C/W maximum at L = 0 inch
THERMAL IMPEDANCE: (Z
OJX): 35
擄C/W maximum
POLARITY:
Diode to be operated with
the banded (cathode) end positive.
MOUNTING SURFACE SELECTION:
The Axial Coefficient of Expansion
(COE) Of this Device is Approximately
+6PPM/擄C. The COE of the Mounting
Surface System Should Be Selected To
Provide A Suitable Match With This
Device.
NOTE 1
No Suffix type numbers are +20% with guaranteed limits for only VZ, lR, and VF.
Units with 鈥淎鈥?suffix are +10% with guaranteed limits for VZ, lR, and VF. Units with
guaranteed limits for all six parameters are indicated by a 鈥淏鈥?suffix for +5.0% units,
鈥淐鈥?suffix for+2.0% and 鈥淒鈥?suffix for +1.0%.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25擄C + 3擄C.
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to
10% of1ZT.
NOTE 2
NOTE 3
NOTE 4
NOTE 5
Reverse leakage currents are measured at VR as shown on the table.
鈭哣
Z is the maximum difference between VZ at lZT and VZ at lZL measured
with the device junction in thermal equilibrium.
