1N2970 thru 1N3015B  
and 1N3993 thru 1N4000A  
10 WATT ZENER DIODES  
S C O T T S D A L E D I V I S I O N  
DESCRIPTION  
APPEARANCE  
These high power 10 W Zener diodes represented by the JEDEC  
registered 1N2970 thru 1N3015B and 1N3993 thru 1N4000A 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 10 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-4  
(DO-203AA)  
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com  
FEATURES  
APPLICATIONS / BENEFITS  
•
JEDEC registered 1N2970 thru 1N3015B and  
•
•
Regulates voltage over a broad operating  
current and temperature range  
Standard voltage tolerances are +/- 5% with B  
suffix, +/-10% with an A suffix, and +/-20% with  
no suffix  
1N3993 thru 1N4000A  
•
•
•
•
Internal solder bond construction  
Hermetically sealed (welded)  
Zener Voltage 3.9V to 200V.  
Also available in JAN, JANTX, and JANTXV  
qualifications per MIL-PRF-19500/124 by  
adding the JAN, JANTX, or JANTXV prefixes to  
part numbers for desired level of screening;  
(e.g. JANTX1N2970B, JANTXV1N3996A, etc.  
Standard polarity is anode to case (stud) for  
1N2970 thru 1N3015B and cathode to case for  
1N3993 thru 1N4000A  
Reverse polarity is cathode to case for 1N2970  
thru 1N3015B and anode to case for 1N3993  
thru 1N4000A by designating R suffix, e.g.  
1N2970RB, 1N3993RA, etc.  
•
Consult factory for +/-2% or +/-1% voltage  
tolerance with a C or D suffix respectively  
•
•
Reverse polarity available  
Nonsensitive to ESD per MIL-STD-750 Method  
1020  
•
•
•
Inherently radiation hard as described in  
Microsemi MicroNote 050  
•
Consult factory for surface mount equivalents
