SMAJ5913 thru SMAJ5956, e3
SILICON 3.0 Watt ZENER DIODE
SCOTTSDALE DIVISION
DESCRIPTION
The SMAJ5913-5956B series of surface mount 3.0 watt Zeners provides
voltage regulation in 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 1N5913 thru 1N5956B with identical electrical characteristics
except it is rated at 3.0 W instead of 1.5 W with the lower thermal resistance
features of this surface mount packaging. These plastic encapsulated Zeners
have a moisture classification of Level 1 with no dry pack required and are
also available in military equivalent screening levels by adding a prefix
identifier as further described in the Features section. Microsemi also offers
numerous other Zener products to meet higher and lower power applications.

NOTES:
1. No suffix indicates a +/-20% tolerance on nominal V
Z
. Suffix A denotes a +/-10% tolerance, B denotes a
+/-5% tolerance, C denotes a 2% tolerance, and D denotes a +/-1% tolerance.
2. Zener voltage (V
Z
) is measured at T
L
= 30
o
C and 90 seconds after application of dc current.
3. 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
.
4. The maximum dc current (I
ZM
) is based only on the maximum power of 3.0 watts at T
L
< 105
o
C. These
values must be reduced by 48% (1.56 W) when mounted on PC boards as described in Maximum Ratings.
