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:

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.

Zener Voltage (V_Z) is measured with junction in thermal equilibrium with 30^oC base temperature. The test currents (I_ZT) 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 18.75^oC .

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 (I_ZTor I_ZK) is superimposed on I_ZTor I_ZK. 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 I_ZMare calculated for a +/-5% tolerance on nominal zener voltage. Allowance has been made for the rise in zener voltage

above V_ZTthat results from zener impedance and the increase in junction temperature as power dissipation approaches 50 watts. In the

case of individual diodes, I_ZMis that value of current that results in a dissipation of 50 watts.

GRAPHS AND CIRCUITS

Typical circuit connections for anode-to-case and

cathode-to-case polarities (standard and reverse

polarities, respectively).
