Microchip Technology 1N2981A is a high-power Zener diode designed for robust voltage regulation applications. This component features a 17V nominal Zener voltage with a tight ±5% tolerance, ensuring precise voltage stabilization. With a maximum power dissipation of 10W, it is suitable for demanding power supply circuits, voltage referencing, and surge protection in industrial, automotive, and aerospace systems. The diode exhibits a low impedance of 4 Ohms (Max) at its test current, contributing to efficient regulation. Its DO-213AA (DO-4) stud mount package facilitates effective heat dissipation and secure mounting in chassis applications. The operating temperature range of -65°C to 175°C underscores its suitability for harsh environmental conditions. The 1N2981A is supplied in bulk packaging.
