1N4678 thru 1N4717-1 DO-7

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-7 Zeners also have an internal-metallurgical-

bond similar to other military requirements for these packages. Microsemi

also offers numerous other Zener products to meet higher and lower power

applications.

DO-7

(DO-204AA)
