JANHCA1N756A

Single Zener Diodes Overview

The JANHCA1N756A is a hermetically sealed silicon Zener diode manufactured by Microchip Technology. It features an 8.2V nominal Zener voltage with a 5% tolerance and a maximum power dissipation of 0.417W (417mW). The device utilizes a DO-7 glass axial leaded package, providing isolation between the case and the electrical circuit. Designed for high-reliability environments, it operates within a temperature range of -65°C to +175°C junction temperature.
