Quality Control: Learn More
Microchip Technology's 1N2973RB is a 9.1V Zener diode from their single Zener diode offering, designed for robust performance. This component features a 10W power dissipation capability and a tight ±5% voltage tolerance. With a low nominal Zener impedance of 2 Ohms (Zzt), it provides stable voltage regulation. The diode is specified for a reverse leakage current of 25 µA at 6.9V. Its forward voltage drop (Vf) is a maximum of 1.5V at 2A. The 1N2973RB utilizes a DO-213AA package with a chassis/stud mount configuration, facilitating efficient thermal management. It operates across a wide temperature range of -65°C to 175°C. This component is suitable for applications in power supplies, voltage regulation circuits, and protection circuitry across various industrial and high-reliability sectors. The part is supplied in bulk packaging.
