1N4689C/TR [Microchip]

The 1N4678 thru 1N4717 series of 0.5 watt Zener Voltage Regulators provides voltage regulation from 1.8V to 43V with standard 5% tolerances and tighter tolerances (2% or 1%) available via suffix letters. These glass axial-leaded DO-35 Zeners feature internal metallurgical bond option (suffix -1), military screening options (prefixes MQ, MX, MV, MSP), and surface mount availability (DO-213AA with UR/UR-1 suffix). They offer flexible axial-lead mounting, are nonsensitive to ESD, have minimal capacitance, and are inherently radiation hard. Operating temperature range is -65°C to +175°C with thermal resistance of 250°C/W junction-to-lead and 310°C/W junction-to-ambient on FR4 board.
