CDLL5285 [Microchip]

The 1N5221BUR thru 1N5281BUR series are 0.5 watt surface mount Zener voltage regulators in hermetically sealed DO-213AA (SOD80 or MLL34) MELF style packages. They provide voltage regulation over a broad operating current and temperature range with nominal voltages from 2.4V to 200V. Standard tolerance is ±5% (B suffix) or ±10% (A suffix), with tighter tolerances of ±2% (C suffix) or ±1% (D suffix) available. Devices are RoHS compliant with 'e3' suffix, offer internal metallurgical bond option with '-1' suffix, and are non-sensitive to ESD per MIL-STD-750. They feature minimal capacitance and inherent radiation hardness as described in Microsemi MicroNote 050.
