1N5913BG 1N5956BG Screening in reference to Available Axial-Leaded 1.5 Watt Glass Zener Diodes MIL-PRF-19500 available 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.

Z Z I , I , I Regulator Current: The dc regulator current (I ), at a specified test point (I ), near breakdown knee (I ). Z ZT ZK Z ZT ZK Regulator Impedance: The small signal impedance of the diode when biased to operate in its breakdown region with Z or Z ZT ZK I applied at I or I respectively. This has also been known as Zener or dynamic impedance (Z or Z ). ZT Z ZK ZT ZK Forward Voltage: The positive dc anode-cathode voltage the device will exhibit at a specified forward current. V F Reverse Current: The dc current flowing from the external circuit into the cathode terminal at the specified voltage V . I R R I Maximum Regulator (Zener) Current: The maximum rated dc current for the specified power rating. ZM T4-LDS-0300, Rev. 1 (6/6/13) 2013 Microsemi Corporation Page 2 of 5
