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 optionally available with an internal-metallurgical-bond option by

adding a “-1” suffix as well as RoHS Compliant by adding an “e3” suffix.

Microsemi also offers numerous other Zener products to meet higher and

lower power applications.

DO-35

(DO-204AH)

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
