SMBG5913 SMBG5956e3, SMBJ5913 SMBJ5956e3 Silicon 2.0 Watt Zener Diodes Available DESCRIPTION The SMB(G/J)5913B SMB(G/J)5956B series of surface mount 2.0 watt Zener diodes provides a selection from 3.3 to 200 volts with tolerance options of 10%, 5% and 2%. This series has the same electrical characteristics as the axial, JEDEC registered 1N5913 - 1N5956 series with the exception of its higher, 2.0 W power rating (versus 1.5 W for the JEDEC series). This is permitted by the lower thermal resistance of the surface mount packaging. The SMBG Gull-wing design in the DO-215AA package provides for visible solder DO-215AA connections. The SMBJ J-bend design in the DO-214AA package permits greater PC board mounting density. The series is available with SnPb plated leaded or RoHS compliant matte- Gull-wing Package tin plating.
