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.
