The 1N5913BG-5956BG series of 1.5 watt Zeners provides voltage regulation in a selection from 3.3 to 200 volts with different tolerances as identified by suffix letter on the part. These glass encapsulated Zeners with a G suffix provide hermetic-sealed qualities and higher rated temperature when required beyond that optionally provided in equivalent plastic-body constructions (P suffix) for the same JEDEC part numbers. Both package options are available by Microsemi. A variety of other Zener product offerings and packages are available by Microsemi to meet higher or lower power and test-current applications.
