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.

* JEDEC Registered Data  
NOTE 1: The JEDEC type numbers shown (B suffix) have a +/-5% tolerance on nominal Zener voltage. The suffix A is used to identify +/-  
10% tolerance; suffix C is used to identify +/-2%; and suffix D is used to identify +/-1% tolerance; no suffix indicates +/-20%  
tolerance.  
NOTE 2: Zener voltage (VZ) is measured after the test current has been applied for 20 +/- 5 seconds. The device shall be suspended by its  
leads with the inside edge of the mounting clips between .375” and .500” from the body. Mounting clips shall be maintained at a  
temperature of 25 +8/ -2oC.  
NOTE 3: The zener impedance is derived when a 60 cycle ac current having an rms value equal to 10% of the dc zener current (IZT or  
IZK) is superimposed on IZT or IZK. Zener impedance is measured at 2 points to ensure a sharp knee on the breakdown curve  
and to eliminate unstable units. See MicroNote 202 for variation in dynamic impedance with different zener currents.  
NOTE 4: The values of IZM are calculated for a +/- 5% tolerance on nominal zener voltage. Allowance has been made for the rise in zener  
voltage above VZT which results from zener impedance and the increase in junction temperature as power dissipation approaches  
400 mW. In the case of individual diodes IZM is that value of current which results in a dissipation of 400 mW at 75oC lead  
temperature at 3/8” from body.  
NOTE 5: The surge for IZSM is a square wave or equivalent half-sine wave pulse of 1/120 sec. duration.
