SMBJ5333B thru SMBJ5388B
Available
Surface Mount Silicon 5 Watt
Zener Diodes
DESCRIPTION
The SMBJ5333B - SMBJ5388B series of surface mount 5.0 watt Zeners provides a selection
from 3.3 to 200 volts with different tolerances as identified by suffix letter on the part number.
It is equivalent to the JEDEC registered 1N5333 thru 1N5388B with identical electrical
characteristics and testing. These parts are available with either Sn/Pb plating or a RoHS
compliant matte-tin finish. This J-bend design (SMBJ) in the DO-214AA allows for greater PC
board mounting density. These plastic encapsulated Zeners have a moisture classification of
“Level 1” with no dry pack required. Microsemi also offers numerous other Zener products to
meet higher and lower power applications.

NOTE 1:
Zener voltage (Vz) is measured at T
L
= 25 C (+8, -2 C). Voltage measurement to be performed 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.
