## Description
The 1N2976B is a high-power Zener diode designed for voltage regulation and transient suppression in demanding industrial and power supply applications. Housed in a robust DO-4 stud-mount package, this single-junction device provides a nominal Zener voltage of 12 V with a 5% tolerance. It is engineered to handle a continuous DC power dissipation of 10 W, with a thermal derating requirement of 83.3 mW/°C for operation above 55 °C. The device supports a wide junction and storage temperature range, extending up to a maximum of 175 °C, ensuring reliability in high-thermal-stress environments.
This component features a standard anode-to-case polarity configuration, facilitating direct chassis mounting for efficient heat sinking. The 1N2976B is suitable for use in voltage clamping circuits, power conversion systems, and protection networks where stable reference voltages or surge suppression are required. Its stud-mount construction provides a secure mechanical and thermal interface, making it appropriate for heavy-duty electronic assemblies where vibration resistance and effective thermal management are critical.
