1N4730A [Semtech]

The 1N4728A thru 1N4764A are a series of Zener diodes with nominal Zener voltages ranging from 3.3V to 100V. They feature low zener impedance, low regulation factor, and a glass passivated junction. The devices offer ±5% Zener voltage tolerance and are guaranteed for high-temperature soldering at 260°C/10S/9.5mm lead length under 5 lbs tension. They come in a hermetically sealed JEDEC DO-41 glass case with plated axial leads, are solderable per MIL-STD 750, and can be mounted in any position. The polarity is denoted by a color band at the cathode end.
