JAN1N4483US

Single Zener Diodes Overview

The JAN1N4483US is a surface mount Zener voltage regulator manufactured by Microchip Technology. It operates within a junction and storage temperature range of -65 to +175 °C and features a steady-state power dissipation of 1.5 W at 25 °C ambient temperature. The device exhibits a nominal Zener voltage of 56 V with a maximum dynamic impedance of 70 Ohms at the test current of 4.5 mA. Maximum reverse current is specified as 25 µA at 44.8 V, while the maximum continuous current reaches 260 mA.
