1N957B, -1 thru 1N992B, -1 DO-35
Silicon 500 mW Zener Diodes
SCOTTSDALE DIVISION
DESCRIPTION
The popular 1N957B thru 1N992B series of 0.5 watt Zener Voltage
Regulators provides a selection from 6.8 to 200 volts in standard 5% or
10% tolerances as well as tighter tolerances identified by different suffix
letters on the part number. These glass axial-leaded DO-35 Zeners are
also available with an internal-metallurgical-bond option by adding a 鈥?1鈥?/div>
suffix. The 1N962B-1 thru 1N992B-1 are available in JAN, JANTX, and
JANTXV military qualifications. Microsemi also offers numerous other
Zener products to meet higher and lower power applications.
