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 (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

temperature of 25 +8/ -2^oC.

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_ZTor

I_ZK) is superimposed on I_ZTor 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_ZMare calculated for a +/- 5% tolerance on nominal zener voltage. Allowance has been made for the rise in zener

voltage above V_ZTwhich results from zener impedance and the increase in junction temperature as power dissipation approaches

400 mW. In the case of individual diodes I_ZMis that value of current which results in a dissipation of 400 mW at 75^oC lead

temperature at 3/8” from body.

NOTE 5: The surge for I_ZSMis a square wave or equivalent half-sine wave pulse of 1/120 sec. duration.
