1N4678 thru 1N4717-1 DO-35

500 mW AXIAL-LEADED ZENER DIODES

S C O T T S D A L E D I V I S I O N

DESCRIPTION

APPEARANCE

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.

DO-35

(DO-204AH)
