1N4678 thru 1N4717-1 DO-7

500 mW AXIAL-LEADED ZENER DIODES

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)

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

respectively to part numbers as well as “-1” suffix

Surface Mount available in DO-213AA package

outline by adding a UR or UR-1 (see separate data

sheet for 1N4678UR thru 1N4717UR-1)

•

Regulates voltage over a broad operating

current and temperature range

Guaranteed maximum voltage regulation 10 µA to

100 µA

•

Voltage selection from 1.8 to 43 V

Standard voltage tolerances are plus/minus 5%

with no suffix

Tight tolerances available in plus or minus 2%

or 1% with C or D suffix respectively

Flexible axial-lead mounting terminals

Nonsensitive to ESD per MIL-STD-750 Method 1020

Capacitance also specified (see Figure 3)

•

DO-35 glass body axial-leaded Zener equivalents

•

are also available (see separate data sheet)

Inherently radiation hard as described in Microsemi

MicroNote 050
