1N5333B thru 1N5388B
Available
Silicon 5 Watt Zener Diodes
DESCRIPTION
The 1N5333B through 1N5388B JEDEC registered series of axial-leaded 5.0 watt Zeners
provides a selection from 3.3 to 200 volts with different tolerances as identified by specific
suffix letter on the part number. These plastic encapsulated Zeners have a moisture
classification of “Level 1” with no dry pack required. They may be operated at high maximum
dc currents with adequate heat sinking due to their comparatively low thermal resistance
design. Microsemi also offers numerous other Zener products to meet higher and lower
power applications.

SYMBOLS & DEFINITIONS
Definition
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature.
Regulator Current: The dc regulator current (I

), at a specified test point (I
ZT
), near breakdown knee (I
ZK
).
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
Maximum Zener Surge Current: The non-repetitive peak value of Zener surge current at a specified wave form.
Reverse Voltage: The reverse voltage dc value, no alternating component.
Zener Voltage: The Zener voltage the device will exhibit at a specified current (I
Z
) in its breakdown region.
Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region at a
specified rms current modulation (typically 10% of I
ZT

JEDEC Registered Data.
NOTE 1:
Zener voltage (Vz) is measured at T
L
= 25
o
C (+8, -2
o
C). Voltage measurement performed at 40 ±10 milliseconds after application of
dc current.
NOTE 2:
The Zener impedance is derived from 1 kHz ac voltage resulting from an ac current modulation having an rms value equal to 10% of the
dc Zener current (I
ZT
or I
ZK
) superimposed on I
ZT
or I
ZK
. See
MicroNote 202
for Zener impedance variation with different operating
currents.
NOTE 3:
The maximum current (I
ZM
) shown is for a ± 5% tolerance devices. The I
ZM
for other tolerances can be calculated using the formula:
I
ZM
= P/V
ZM
where V
ZM
is the V
Z
at the high end of the voltage tolerance specified and P is the rated power for the method of
mounting.
NOTE 4:
The surge current (I
ZSM
) is specified as the maximum peak of a non-recurrent half-sine wave of 8.3 ms duration.
