The 1N4678 thru 1N4717 series of 0.5 watt Zener Voltage Regulators

provides a selection from 1.8 to 43 volts in standard 5% 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 “-1” suffix similar to military

requirements on similar Zeners. Microsemi also offers numerous other

Zener products to meet higher and lower power applications.

•

JEDEC registered 1N4678 thru 1N4717

Internal metallurgical bond option available by

adding a “-1” suffix

Options for screening in accordance with MIL-PRF-

19500 for JAN, JANTX, JANTXV, and JANS are

available by adding MQ, MX, MV, or MSP prefixes

respectively to part numbers

Surface Mount available in DO-213AA package
