1N4729AUR [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 of +/- 5% (with "A" suffix) and 10% (no suffix), tight tolerances of +/-2% or +/-1% (with C or 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.
