10 WATT ZENER DIODESS C O T T S D A L E D I V I S I O N

1N2970 thru 1N3015Band 1N3993 thru 1N4000A

DESCRIPTION APPEARANCE

These high power 10 W Zener diodes represented by the JEDECregistered 1N2970 thru 1N3015B and 1N3993 thru 1N4000A series providevoltage regulation in a selection over a 3.9 V to 200 V broad range of voltages. They may be operated up to 10 W with adequate mounting andheat sinking with their low thermal resistance. These Zeners are alsoavailable in JAN, JANTX, JANTXV military qualifications. Microsemi alsooffers numerous other Zener products to meet higher and lower power applications.

NOTES: 1. 1N3993 - 1N4000 series: suffix A indicates +/-5% tolerance, no suffix indicates +/-10% tolerance. 1N2970 – 1N3015 series: suffix Bindicates +/- 5% tolerance, suffix A indicates +/-10%, no suffix indicates +/-20% tolerance. If tighter tolerance is required, consultfactory.

2. The electrical characteristics are measured after allowing the device to stabilize for 90 seconds with 30o

C Base temperature.3. The zener impedance (ZZT) is derived from the 60 Hz 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. When making zener impedance measurements at the IZK test point, it maybe necessary to insert a 60 Hz band pass filter between the diode and voltmeter to avoid errors resulting from low level noise signals. Acurve showing the variation of zener impedance vs. zener current for three representative types is shown in Figures 2 and 3. Also seeMicrosemi MicroNote 202.

4. These values of IZM may be exceeded in the case of individual diodes. The values shown are calculated for the worst case that is a unitof +/-5% tolerance at the high voltage end of its tolerance range. Allowance has also been made for the rise in zener voltage above VZT,which results from zener impedance and the increase in junction temperature as power dissipation approaches 10 watts.
