500 mW GLASS SURFACE MOUNT ZENER DIODES 1N5221UR thru 1N5281BUR, e3 (or MLL5221 thru MLL5281B, e3)

2022-08-05

●DESCRIPTION
▲The 1N5221BUR thru 1N5281BUR series of 0.5 watt Zener Voltage Regulators provides a surface mount equivalent to the popular JEDEC registered 1N5221B to 1N5281B for 2.4 to 200 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. These are also available with an internal-metallurgical-bond option by adding a “-1” suffix (see separate data sheet). Microsemi also offers numerous other Zener products to meet higher and lower power applications.
●FEATURES
▲Surface mount equivalents to the JEDEC registered 1N5221 thru 1N5281B series
▲Hermetically sealed surface mount package
▲RoHS Compliant devices available by adding “e3” suffix
▲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 1N5221 thru 1N5281B series
●APPLICATIONS / BENEFITS
▲Regulates voltage over a broad operating current and temperature range
▲Selection from 2.4 to 200 V
▲Standard voltage tolerances are plus/minus 5% with B suffix identification and 10 % with A suffix
▲Tight tolerances available in plus or minus 2% or 1% with C or D suffix respectively
▲Nonsensitive to ESD per MIL-STD-750 Method 1020
▲Minimal capacitance (see Figure 3)
▲Inherently radiation hard as described in Microsemi MicroNote 050
