SMAJ5913 thru SMAJ5956, e3
SILICON 3.0 Watt ZENER DIODE
S C O T TS DALE DIVISION
DESCRIPTION
PACKAGE
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
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.
DO-214AC or BA
(SMAJ)
FEATURES
APPLICATIONS / BENEFITS
Surface mount equivalent to 1N5913 to 1N5956B
