DESCRIPTION
APPEARANCE
These high power 50 W Zener diodes represented by the JEDEC registered
1N2804 thru 1N2846B and 1N4557 thru 1N4564B 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.

NOTES:
1.
The JEDEC type numbers shown (B suffix) have a +/- 5% tolerance on nominal zener voltage. The suffix A is used to identify +/-10%
tolerance; no suffix indicates +/-20% tolerance. If tighter tolerance is required, consult factory. Standard polarity units have the anode
connected to the case. Reverse polarity (cathode-to-case) units are available and are indicated by suffix R in the part number.
2.
3.
Zener Voltage (VZ) is measured with junction in thermal equilibrium with 30oC base temperature. The test currents (IZT) have been selected
so that at nominal voltages the dissipation is a constant 12.5 watts. This results in a nominal junction temperature rise of 18.75oC .
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 six representative types is
shown in Figure 3. Also see MicroNote 202 for further information.
The values of IZM are calculated for a +/-5% tolerance on nominal zener voltage. Allowance has been made for the rise in zener voltage
above VZT that results from zener impedance and the increase in junction temperature as power dissipation approaches 50 watts. In the
case of individual diodes, IZM is that value of current that results in a dissipation of 50 watts.
