SMBJ5333B thru SMBJ5388B Surface Mount Silicon 5 Watt Available Zener Diodes DESCRIPTION The SMBJ5333B - SMBJ5388B series of surface mount 5.0 watt Zeners provides 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 1N5333 thru 1N5388B with identical electrical characteristics and testing. These parts are available with either Sn/Pb plating or a RoHS compliant matte-tin finish. This J-bend design (SMBJ) in the DO-214AA allows for greater PC board mounting density. These plastic encapsulated Zeners have a moisture classification of DO-214AA Level 1 with no dry pack required. Microsemi also offers numerous other Zener products to J-Bend Package meet higher and lower power applications. NOTE: All SMB series are equivalent to prior SMS package identifications. Important: For the latest information, visit our website SMBJ5333B thru SMBJ5388B MECHANICAL and PACKAGING CASE: Void-free transfer molded thermosetting epoxy body meeting UL94V-0. TERMINALS: C-bend (modified J-bend) tin-lead or RoHS compliant annealed matte-tin plating solderable per MIL-STD-750, method 2026. MARKING: Part number without SMBx prefix (e.g. 5334B, 5334Be3, MX5348C, 5376A, etc.). POLARITY: Cathode indicated by band.
