SMAJ5913Be3 – SMAJ5956Be3
Compliant
Silicon 3.0 Watt Zener Diode
DESCRIPTION
The SMAJ5913Be3 – SMAJ5956Be3 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 1N5913B through 1N5956B series
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.

SYMBOLS & DEFINITIONS
Definition
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage V
R
and temperature.
Regulator Current: The dc regulator current (I
Z
), 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 Forward Voltage: The maximum forward voltage the device will exhibit at a specified current.
Reverse Voltage: The dc voltage applied in the reverse direction below the breakdown region.
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
or I
ZK
) and superimposed on I
ZT
or I
ZK
respectively.

Suffix B (shown) denotes a +/-5% tolerance on nominal V
Z
, A denotes a +/-10% tolerance, C denotes a 2% tolerance, and D denotes a
+/-1% tolerance.
Zener voltage (V
Z
) is measured at T
L
= 30
o
C and 90 seconds after application of dc current.
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
.
o
The maximum dc current (I
ZM
) is based only on the maximum power of 3.0 watts at T
L
< 105 C. These values must be reduced by
48% (1.56 W) when mounted on PC boards as described in
Maximum Ratings.
