1N5281B [Microchip]

The popular 1N5221B-1 thru 1N5281B-1 series of 0.5 watt Zener voltage regulators provides a selection from 2.4 to 200 volts in standard 5% or 10% tolerances as well as tighter tolerances identified by different suffix letters on the part number. These glass, axial-leaded DO-35 Zeners are also available in various up-screening levels by adding a prefix identifier. Features include JEDEC registration, internal metallurgical bond, up-screening in reference to MIL-PRF-19500, and RoHS compliant versions (commercial grade). Benefits include voltage regulation over a broad operating current and temperature range, extensive voltage selection, flexible axial-lead mounting, non-sensitivity to ESD, minimal capacitance, and inherent radiation hardness.
