ZENER DIODE 18Ohm ±5% 4.3V 2μA @ 1V -65°C~175°C 500mW 2 Terminations DO-204AH, DO-35, Axial
1N749A-1 Overview
The reverse leakage current needed to power this electric device is 2μA @ 1V.Zener single diode is a maximum voltage (Tol) that can be supplied at 5%.A zener current of 2μA makes it highly flexible in terms of design.Setting the working test voltage to 20mA will allow this device to operate.For its operation, the maximum voltage - Forward (Vf) 1.1V @ 200mA is supplied.This device requires a peak reverse voltage of 2μA to function fully.
1N749A-1 Features
reverse leakage current of 2μA @ 1V
2μA @ 1V is the maximum voltage (Tol)
the zener current of 2μA
the working test voltage to 20mA
minimal dynamic impedance is 20mA
1N749A-1 Applications
There are a lot of Microsemi Corporation
1N749A-1 applications of zener single diodes.
