IN4678UR-1 thru 1N4717UR-1

(or MLL4678-1 thru MLL4717UR-1)

METALLURGICALLY BONDED GLASS

SURFACE MOUNT 0.5 WATT ZENERS

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

DESCRIPTION

APPEARANCE

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

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

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

current of 50 µA. These have an internal-metallurgical-bond option as

identified with the “-1” suffix. This type of internally bonded Zener package

construction is also available with equivalent military screening as described

in the Features section. 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 1N4678

•

Regulates voltage over a broad operating current and

thru 1N4717 series

temperature range

• Internal metallurgical bond with the “-1” suffix

•

Extensive selection from 1.8 to 43 V

• Options for screening in accordance with MIL-PRF-

19500 for JAN, JANTX, JANTXV, and JANS are

available by adding MQ, MX, MV, MSP respectively to

part numbers; (e.g. MX1N4678UR-1, MV1N4701UR-1,

MSP1N4709DUR-1, etc.)

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)

•

• Nonbonded types also available without the “-1” suffix

for both the axial and surface mount packages

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

equivalents also available per JEDEC registration with

part numbers 1N4678 thru 1N4717 on separate data

sheets

Inherently radiation hard as described in Microsemi

MicroNote 050

MAXIMUM RATINGS

MECHANICAL AND PACKAGING

• Operating and Storage temperature: -65^ºC to +175^ºC

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

• Thermal Resistance: 100 ^ºC/W junction to end cap, or

250^ºC/W junction to ambient when mounted on FR4 PC

board (1 oz Cu) with recommended footprint (see last

page Figure 1)

or MLL34) MELF style package

• 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

• Steady-State Power: 0.5 watts at end cap temperature

_EC< 125^oC or at ambient T_A< 50^ºC when mounted on

FR4 PC board as described for thermal resistance

above (see Figure 2 for derating)

• 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)

• Forward voltage @100 mA: 1.5 volts

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

• WEIGHT: 0.04 grams

• See package dimensions on last page
