1N5739D [Microchip]

The 1N5728 thru 1N5757 series are 0.5 watt Zener Voltage Regulators in DO-35 glass axial-leaded package. They provide voltage regulation from 4.7 to 75 volts with standard 5% tolerance (B suffix) and tighter tolerances of 2% (C suffix) or 1% (D suffix). Options include internal metallurgical bond (suffix -1), military screening (prefixes MQ, MX, MV, MSP), and surface mount equivalents (DO-213AA with UR or UR-1 suffix). The devices are non-sensitive to ESD, have minimal capacitance, and are inherently radiation hard. They feature flexible axial-lead mounting and are hermetically sealed.
