SMBJ5333B thru SMBJ5388B
Available
Surface Mount Silicon 5 Watt 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 “Level 1” with no dry pack required. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

SYMBOLS & DEFINITIONS Definition
Reverse Current: The maximum reverse (leakage) current that will flow at the specified voltage and temperature. Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK). Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating. Maximum Zener Surge Current: The non-repetitive peak value of Zener surge current at a specified wave form. Reverse Voltage: The reverse voltage dc value, no alternating component. Zener Voltage: The Zener voltage the device will exhibit at a specified current (IZ) in its breakdown region. Dynamic Impedance: The small signal impedance of the diode when biased to operate in its breakdown region at a specified rms current modulation (typically 10% of IZT or IZK) and superimposed on IZT or IZK respectively.
