CDLL5521A [Microchip]

The 1N5518BUR-1 thru 1N5546BUR-1 series are 0.5 watt glass surface mount Zener voltage regulators. They provide a voltage range from 3.3 to 33 volts with tolerances from ±1% to 20% (standard ±5% with B suffix). These devices feature an internal metallurgical bond and are available in JAN, JANTX, JANTXV military qualifications. RoHS compliant versions are available for commercial grade. The package is hermetically sealed glass DO-213AA (MELF). They regulate voltage over a broad operating current and temperature range, are nonsensitive to ESD, have minimal capacitance, and are inherently radiation hard.
