Microchip Technology 1N2978A is a 14V Zener diode with a power rating of 10W. This component features a ±5% voltage tolerance and a low reverse leakage current of 10 µA at 10.5V. The Zener impedance (Zzt) is a maximum of 3 Ohms. Designed for robust applications, the 1N2978A utilizes a DO-213AA package for chassis or stud mounting, offering efficient thermal management. The forward voltage (Vf) is specified at 1.5V maximum at 2A. This device operates reliably across a wide temperature range of -65°C to 175°C. It is commonly employed in power supply regulation, voltage clamping, and overvoltage protection circuits within industrial and telecommunications equipment.
