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 Important: For the latest information, visit our website SMAJ5913Be3 SMAJ5956Be3 MECHANICAL and PACKAGING CASE: Void-free transfer molded thermosetting epoxy body meeting UL94V-0.
