1N5754C [Microchip]

This series of 0.5 watt Zener diodes in DO-35 package offers voltage regulation from 4.7V to 75V with standard 5% tolerance (B suffix) and optional tighter tolerances of 2% (C suffix) or 1% (D suffix). The devices feature internal metallurgical bond option (suffix -1), are JEDEC registered, and are available in surface mount (DO-213AA) and DO-7 glass body axial-leaded equivalents. They are hermetically sealed, have flexible axial-lead terminals, are non-sensitive to ESD, have minimal capacitance, and are inherently radiation hard.
