1N5913BG – 1N5956BG
Available
Axial-Leaded 1.5 Watt Glass Zener Diodes
DESCRIPTION
The 1N5913BG-5956BG series of 1.5 watt Zeners provides voltage regulation in a selection from 3.3 to 200 volts with a variety of tolerances available. They are also available in various military equivalent screening levels for high reliability. These glass encapsulated Zeners with a G suffix provide hermetic-sealed qualities and higher rated temperature beyond that optionally provided in equivalent plastic-body constructions (P suffix) for the same JEDEC part numbers. Both package options are available from Microsemi.
Screening in reference to MIL-PRF-19500

SYMBOLS & DEFINITIONS Definition
Zener Voltage: The Zener voltage the device will exhibit at a specified current (IZ) in its breakdown region. Regulator Current: The dc regulator current (IZ), at a specified test point (IZT), near breakdown knee (IZK). Regulator Impedance: The small signal impedance of the diode when biased to operate in its breakdown region with IZT applied at IZ or IZK respectively. This has also been known as Zener or dynamic impedance (ZZT or ZZK). Forward Voltage: The positive dc anode-cathode voltage the device will exhibit at a specified forward current.
Reverse Current: The dc current flowing from the external circuit into the cathode terminal at the specified voltage VR.
Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating.
