Silicon 5 Watt Zener Diodes
DESCRIPTION
The 1N5333B through 1N5388B JEDEC registered series of axial-leaded 5.0 watt Zeners
provides a selection from 3.3 to 200 volts with different tolerances as identified by specific
suffix letter on the part number. These plastic encapsulated Zeners have a moisture
classification of “Level 1”
with no dry pack required. They may be operated at high maximum
dc currents with adequate heat sinking due to their comparatively low thermal resistance
design. Microsemi also offers numerous other Zener products to meet higher and lower
power applications.

JEDEC Registered Data.
NOTE 1: Zener voltage (Vz) is measured at TL = 25 oC (+8, -2 oC). Voltage measurem ent perform ed at 40 ±10 millisecon ds after application of
dc current.
NOTE 2: The Zener impedance is derived from 1 kHz ac voltage resulting from an ac current modulation having an rms value equal to 10% of the
dc Zener current (IZT or IZK) superimposed on IZT or IZK. See MicroNote 202 for Zener impedance variation with different operating
currents.
NOTE 3: The ma xi m u m c urr e nt (IZM) shown is for a ± 5% tolerance devices. Th e 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 pow er 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.
