Low Voltage Surface Mount 500 mW Avalanche Diodes IN5518BUR-1 thru 1N5546BUR-1 (or MLL5518B-1 thru MLL5546B-1)

2022-08-05

●DESCRIPTION
▲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.
●FEATURES
▲Surface mount equivalent to JEDEC registered 1N5518 thru 1N5546 series
▲Internal metallurgical bond with the “-1” suffix
▲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
●APPLICATIONS / BENEFITS
▲Regulates voltage over a broad operating current and temperature range
▲Extensive selection from 3.3 to 33 V
▲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
