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)

FEATURES  
APPLICATIONS / BENEFITS  
JEDEC registered 1N957B(-1) to 1N992B(-1) series  
Regulates voltage over a broad operating  
current and temperature range  
Extensive selection from 6.8 to 200 V  
Standard voltage tolerances are plus/minus 5%  
with B suffix, 10 % with A suffix identification  
Tight tolerances available in plus or minus 2%  
or 1% with C or D suffix respectively  
Internal metallurgical bond option available by  
adding a “-1” suffix  
Also available in JAN, JANTX, and JANTXV  
qualifications per MIL-PRF-19500/117 by adding the  
JAN, JANTX, or JANTXV prefixes to part numbers  
for desired level of screening as well as “-1” suffix;  
(e.g. JANTX1N962B-1, JANTXV1N986C-1, etc.)  
Flexible axial-lead mounting terminals  
Military Surface Mount equivalents also available in  
DO-213AA by adding a UR-1 suffix in addition to the  
JAN, JANTX, and JANTXV prefix; e.g.  
Nonsensitive to ESD per MIL-STD-750 Method  
1020  
JANTX1N962BUR-1 (see separate data sheet)  
Minimal capacitance (see Figure 3)  
Commercial Surface Mount equivalents available as  
MLL957B to MLL992B or with “-1” suffix for bonded  
in the DO-213AA MELF style package (consult  
factory for others)  
Inherently radiation hard as described in  
Microsemi MicroNote 050  
DO-7 glass body axial-leaded Zener equivalents are  
also available
