    Products Detail

    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 feature internal solder bond construction, hermetically sealed (welded) package, and are available in standard and reverse polarities. The devices are qualified per MIL-PRF-19500/124 in JAN, JANTX, and JANTXV grades. RoHS compliant versions are available for commercial grade by adding the 'e3' suffix. They regulate voltage over a broad range of current and temperature with standard voltage tolerances of +/- 5%. The diodes are non-sensitive to ESD per MIL-STD-750 method 1020 and inherently radiation hard as described in Microsemi MicroNote 050.

    Key Features
