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 “-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 (
V
Z
) 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
o
temperature of 25 +8/ -2 C.
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 (I
ZT
or
I
ZK
) is superimposed on I
ZT
or I
ZK
. 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
I
ZM
are calculated for a +/- 5% tolerance on nominal zener voltage. Allowance has been made for the rise in zener
voltage above V
ZT
which results from zener impedance and the increase in junction temperature as power dissipation approaches
o
400 mW. In the case of individual diodes I
ZM
is that value of current which results in a dissipation of 400 mW at 75 C lead
temperature at 3/8” from body.
NOTE 5:
The surge for I
ZSM
is a square wave or equivalent half-sine wave pulse of 1/120 sec. duration.
