CDLL5273D [Microchip]

These are 500 mW glass surface mount Zener diodes in a hermetically sealed DO-213AA (SOD80 or MLL34) MELF style package. They provide voltage regulation from 2.4V to 200V with standard tolerances of ±5% (B suffix) and ±10% (A suffix), with tighter tolerances available (±2% with C suffix, ±1% with D suffix). The devices feature RoHS compliance (with e3 suffix), internal metallurgical bond option (with -1 suffix), and are available as surface mount equivalents to JEDEC registered 1N5221 through 1N5281B series. They are non-sensitive to ESD, have minimal capacitance, and are inherently radiation hard.
