Zener Diodes
DESCRIPTION
The S MB J5 33 3B - SMBJ53 88B s eries of s ur fac e m ou n t 5.0 watt Zen ers provides a selec tion
from 3 . 3 to 20 0 volt s wit h d iff eren t t oler an c es as i den t ified b y su ffi x let ter on t h e part n um b er.
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 finis h. This J-bend des ign ( SMBJ) in the DO-214AA allows fo r great er PC
board mounting density. These plasti c en capsu lated Zeners have a mois tu r e class ification of
“Level 1” wit h no d ry p ack requ ired . Micr osem i al so offer s n um erou s ot h er Zen er p rod u ct s to
meet higher and lower power applicati ons .

NOTE 1: Zener voltage (Vz) is measured at TL = 25 oC (+8, -2 oC). Voltage measurement to be performed 40 ±10 milliseconds af t er app lic atio n
of dc current.
NOTE 2: The Zener impedance is derived from 1 kHz ac voltage resulting fr om an ac current modulation having an rms valu e equal to 10% of th e
dc Zener curre nt (IZT or IZK) superimposed on IZT or IZK. See MicroNote 202 for Zener im pedance variation with differen t operating
currents.
NOTE 3: The ma xi m u m curr ent (IZM) shown is for a ± 5% tolerance devices. The IZM for other tolerances can be calculated using the formula:
IZM = P/VZM where VZM is the VZ at the high end of the voltage tolerance specified and P is the rated power for the method of mounting.
NOTE 4: The su rge current (IZSM) is specified as the maximum peak of a non-r e cu rr ent half-sine wave of 8.3 ms duration.
