DESCRIPTION
Screening in
reference to
MIL-PRF-19500
available
This surface mountable 1.5 W Zener diode series in the JEDEC DO-213AB package is similar
in electrical features to the JEDEC registered 1N5913B through 1N5956B axial-leaded
package for 3.3 to 200 V. It is an ideal selection for applications of high density and low
parasitic requirements. Due to its glass hermetic qualities and metallurgically enhanced
internal contacts, it may also be used for high reliability applications when required by a source
control drawing (SCD) or screening in accordance with MIL-PRF-19500 as described in
Features below.

Z
) in its breakdown region.
Regulator Current: The dc regulator current (I

).
Regulator Impedance: The small signal impedance of the diode when biased to operate in its breakdown region with
I
ZT
applied at I

or Z
ZK
).
Forward Voltage: The positive dc anode-cathode voltage the device will exhibit at a specified forward current.
Reverse Current: The dc current flowing from the external circuit into the cathode terminal at the specified voltage V

NOTES:
1. Zener voltage (V
Z
) is measured at end cap temperatures T
EC
= 30
o
C. Voltage measurement to be performed 90 seconds after
application of dc current.
2.
The Zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to
10% of the dc Zener current (I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
.
This product series has also been previously identified as the CDLL5913B through CDLL5956B series that included the
enhanced metallurgical bond. This alternate name may still be used.
