DESCRIPTION

APPEARANCE

The 1N5518BUR-1 thru 1N5546BUR-1 series of 0.5 watt glass surface

mount Zener voltage regulators provides a selection from 3.3 to 33 volts in

standard 5% tolerances as well as tighter tolerances identified by different

suffix letters on the part number. These have an internal-metallurgical-bond

option as identified by the “–1” suffix. This internally bonded Zener package

construction is also in JAN, JANTX, and JANTXV military qualifications.

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

1N5518 thru 1N5546 series

and temperature range

•

Internal metallurgical bond with the “-1” suffix

•

Extensive selection from 3.3 to 33 V

Also available in JAN, JANTX, and JANTXV

qualifications per MIL-PRF-19500/437 by adding

the JAN, JANTX, or JANTXV prefixes to part

numbers for desired level of screening; (e.g.

JANTX1N4099UR-1, JANTXV1N4109CUR-1, etc.)

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 1N5518 thru 1N5546 on

separate data sheets

Standard voltage tolerances are plus/minus 5% with

a “B” suffix, e.g. 1N5518BUR-1, etc.

•

Tight tolerances available in plus or minus 2% or 1%

with C or D suffix respectively, e.g. 1N5518CUR-1,

1N5518DUR-1, etc.

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

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
