ZENER DIODE 2.2kOhm ±5% 180V 5μA @ 136.8V -65°C~175°C 500mW 2 Terminations DO-204AA, DO-7, Axial
1N991B Overview
The reverse leakage current needed to power this electric device is 5μA @ 136.8V.Zener single diode is a maximum voltage (Tol) that can be supplied at 5%.As part of the operation, the maximum voltage - Zener (Nom) is reduced to 180V.Setting the working test voltage to 0.68mA will allow this device to operate.When the voltage (Temp Coeff) reaches diodes peak, diode reaches 198mV/°C.For its operation, the maximum voltage - Forward (Vf) 1.1V @ 200mA is supplied.
1N991B Features
reverse leakage current of 5μA @ 136.8V
5μA @ 136.8V is the maximum voltage (Tol)
the working test voltage to 0.68mA
minimal dynamic impedance is 0.68mA
1N991B Applications
There are a lot of Microsemi Corporation
1N991B applications of zener single diodes.
