DESCRIPTION
APPEARANCE
These high power 50 W Zener diodes represented by the JEDEC
registered 1N3305 thru 1N3350B and 1N4549 thru 1N4556B series provide
voltage regulation in a selection over a 3.9 V to 200 V broad range of
voltages. They may be operated up to 50 W with adequate mounting and
heat sinking with their low thermal resistance. These Zeners are also
available in JAN, JANTX, JANTXV military qualifications. Microsemi also
offers numerous other Zener products to meet higher and lower power
applications.
DO- 5
(DO-203AB)

See further notes on following page
NOTES:
1. When using JEDEC numbers an R suffix should be used to signify reversed polarity. The suffixes A and B indicate tolerances
of 10% and 5% respectively. No suffix or just R denotes +/-20% tolerance. Example: 1N3319RB is a REVERSED polarity,
20 volt unit having a +/-5% tolerance on Zener Voltage.
2. Zener Voltage (VZ) is measured with junction in thermal equilibrium with 30oC stud temperature.
3. The Zener impedance is derived from the 60 cycle ac voltage, which results when an ac current having an rms value equal to
10% of the dc zener current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at 2 points to ensure a
sharp knee on the breakdown curve and to eliminate unstable units. A curve showing the variation of zener impedance vs.
zener current for three representative types is shown in Figure 2. Also see Microsemi MicroNote 202.
