DESCRIPTION

APPEARANCE

The 1N4678UR thru 1N4717UR series of 0.5 watt glass surface mount

DO-213AA Zener voltage regulators provides selection from 1.8 to 43 volts

in standard 5% tolerances as well as tighter tolerances at a very low test

current of 50 µA. These are also available with an internal-metallurgical-

bond option by adding a “-1” suffix (see separate data sheet) including

military upgrade screening options. Microsemi also offers numerous other

Zener products to meet higher and lower power applications.

DO-213AA

FEATURES

APPLICATIONS / BENEFITS

• Surface mount equivalent to JEDEC registered

•

Regulates voltage over a broad operating current and

1N4678 thru 1N4717 series

temperature range

• Internal metallurgical bond option available by

adding a “-1” suffix (see separate data sheet for

same part numbers with “-1” suffix)

• DO-7 or DO-35 glass body axial-leaded Zener

equivalents also available per JEDEC registration

(see separate data sheet for part numbers 1N4678

thru 1N4717 series

•

Extensive 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 additional C or D suffix respectively

Hermetically sealed surface mount package

Nonsensitive to ESD per MIL-STD-750 Method 1020

Minimal capacitance (see Figure 3)

•

Inherently radiation hard as described in Microsemi

MicroNote 050

MAXIMUM RATINGS

MECHANICAL AND PACKAGING

• Operating and Storage temperature: -65^ºC to

• CASE: Hermetically sealed glass DO-213AA (SOD80

+175^ºC

or MLL34) MELF style package

• Thermal Resistance: 150^ºC/W junction to end cap

and 300^ºC/W junction to ambient when mounted on

FR4 PC board (1 oz Cu) with recommended footprint

(see last page Figure 1)

• Steady-State Power: 0.5 watts at end cap

temperature T_EC< 100^oC or ambient temperature T_A

< 25^ºC when mounted on FR4 PC board as

described for thermal resistance above (see Figure

2 for derating)

• TERMINALS: End caps tin-lead plated solderable per

MIL-STD-750, method 2026

• POLARITY: Cathode indicated by band where diode

is to be operated with the banded end positive with

respect to the opposite end for Zener regulation

• MARKING: cathode band only

• TAPE & REEL option: Standard per EIA-481-1-B with

12 mm tape, 2000 per 7 inch reel or 5000 per 13 inch

reel (add “TR” suffix to part number)

• WEIGHT: 0.04 grams

• See package dimensions on last page

• Forward voltage @100 mA: 1.5 volts (max)

• Solder Temperatures: 260 ^ºC for 10 s (max)
