The HZ6B1 is a Zener Diode Pack manufactured by Semtech. It is packaged as a DO-35, and is RoHS compliant. This diode is designed to provide highly reliable voltage regulation in a variety of applications, such as voltage regulation for power supplies, over voltage protection, and EMI/RFI suppression. The HZ6B1 has a nominal zener voltage of 6.1V for improved reliability and consistent performance. The diode is constructed with a glass passivated junction to achieve high temperature stability, and has an electrically isolated heat sinking mounting surface for effective thermal performance. It also has a low series resistance, reverse/leakage current, and low forward voltage drop, making it an ideal choice for a wide range of applications.
