DESCRIPTION
These high power 50W Zener diodes represented by the JEDEC registered
1N3305B thru 1N3350B and 1N4549B thru 1N4556B series provide voltage
regulation in a selection over a 3.9V to 200V 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)
FEATURES
¾ JEDEC registered 1N3305B thru 1N3350B and 1N4549B thru 1N4556B
¾ Internal solder bond construction
¾ Hermetically sealed (welded)
¾ Zener Voltage 3.9V to 200V.
¾ Also available in JAN, JANTX, and JANTXV qualifications per MIL-PRF-
19500/358 by adding the JAN, JANTX, or JANTXV prefixes to part
numbers for desired level of screening; (e.g. JANTX1N3305B,
JANTXV1N3318B, etc.
¾ Standard polarity is anode to case
¾ Reverse polarity with cathode to case by designating R suffix in part number,
e.g. 1N3305RB, etc.
¾ Consult factory for surface mount equivalents

* JEDEC Registered Data.
** Not JEDEC Data.
† Have JAN and JANTX and TXV Qualifications to MIL-S-19500/358.
See further notes on following page.
NOTES:
1. The JEDEC type numbers shown (B suffix) have a +/- 5% tolerance on nominal zener voltage. If other
tolerance is required consult factory. The suffix A is used to identify +/-10% tolerance; no suffix or just R
indicates +/-20% tolerance: C suffix indicates +/-2% tolerance; and D suffix indicates +/-1%. 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.
