1N957B, -1 thru 1N992B, -1 DO-35  
Silicon 500 mW Zener Diodes  
S C O T T S D A L E D I V I S I O N  
DESCRIPTION  
APPEARANCE  
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 “-1”  
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.  
DO-35  
(DO-204AH)
