DESCRIPTION
The JEDEC registered 1N2970B through 1N3015B and 1N3993A through 1N3998A series are
10W Zener diodes with voltage regulation values between 3.9 and 200V. They are available
in JAN, JANTX, and JANTXV military qualification grades on most voltage values.
Qualified Levels:
JAN, JANTX, and
JANTXV
Important: For the latest information, visit our website http://www.microsemi.com.
FEATURES
