1N5333B thru 1N5388B, e3
Silicon 5 Watt Zener Diodes
SCOTTSDALE DIVISION
DESCRIPTION
The 1N5333-5388B JEDEC registered series of axial-leaded 5.0 watt
Zeners provides voltage regulation in 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 moisture classification of Level 1
with no dry pack required and are also available in various military
equivalent screening levels by adding a prefix identifier as also described in
the Features section. They may be operated at high maximum dc currents
with adequate heat sinking with their comparatively low thermal resistance
design. Microsemi also offers numerous other Zener products to meet
higher and lower power applications.

*JEDEC Registered Data.
NOTE 1:
Devices listed above with B suffix have ±5% tolerance, A suffix designates ±10% tolerance, C suffix designates ±2%
tolerance, and D suffix designates ±1% tolerance. No suffix designates ±20%.
o
o
NOTE 2:
Zener voltage (Vz) is measured at T
L
= 25 C (+8, -2 C). Voltage measurement performed at 40 ±10 milliseconds
after application of dc current.
NOTE 3:
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 Micro Note 202 for zener impedance
variation with different operating currents.
NOTE 4:
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 5:
The surge current (I
ZSM
) is specified as the maximum peak of a non-recurrent half-sine wave of 8.3 ms duration.
NOTE 6:
Voltage regulation (ΔV
Z
) is the difference between the voltage measured at 10% and 50% of I
ZM
.
