1N4739AUR [Microchip]

This surface mountable 1 watt Zener diode series is electrically equivalent to the 1N4728A thru 1N4764A registration in the DO-41 equivalent package except that it meets the JEDEC surface mount outline DO-213AB. It is an ideal selection for applications of high density and low parasitic requirements for voltage regulation. Standard voltage tolerance is +/- 5% with tighter tolerances available down to 1%. With its glass hermetic qualities, it may also be used for high reliability applications when required by a source control drawing (SCD). Features include Zener voltages from 3.3V to 100V, standard voltage tolerances +/-5% (A suffix) and 10% (no suffix), tight tolerances +/-2% (C suffix) or +/-1% (D suffix), options for MIL-PRF-19500 screening, surface mount equivalents available as SMAJ4728A to SMAJ4764A, RoHS compliant devices available with e3 suffix, and plastic body axial-leaded equivalents available as 1N4728A to 1N4764A. Benefits include voltage regulation over a broad operating current and temperature range, wide selection from 3.3 to 100V, leadless package for surface mounting, ideal for high density mounting, nonsensitive to ESD, hermetically sealed glass package, specified capacitance, and inherent radiation hardness.
