DESCRIPTION APPEARANCE
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.

NOTES:
1. No suffix indicates a +/-20% tolerance on nominal VZ. Suffix A denotes a +/-10% tolerance, B denotes a +/-5% tolerance, C denotes a
2% tolerance, and D denotes a +/-1% tolerance. Also add a G suffix for Glass construction, e.g. 1N5956BG (P suffix designates plastic
body options described by separate data sheet).
2. Zener voltage (VZ) is measured at TL = 30oC and 90 seconds after application of dc current.
3. The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the
dc zener current (IZT or IZK) is superimposed on IZT or IZK. See MicroNote 202 for zener impedance variation with different operating
currents.
