1N5997B [Microchip]

The 1N5985 thru 1N6031 series are 0.5 watt Zener Voltage Regulators in a DO-35 (DO-204AH) glass axial-leaded package. They provide a wide voltage range from 2.4V to 200V with standard tolerances of 5% (B suffix) or 10% (A suffix), and tighter tolerances of 2% (C suffix) or 1% (D suffix). The series is JEDEC registered and offers military screening levels (JAN, JANTX, JANTXV, JANS) with appropriate prefixes. They are RoHS compliant with e3 suffix, and surface mount equivalents (MLL5985 to MLL6031) are available. Features include ESD non-sensitivity, minimal capacitance, and inherent radiation hardness.
