Microchip Technology's 1N4471D is a 1.5W Zener diode designed for precise voltage regulation. Featuring a nominal Zener voltage (Vz) of 18V with a tight tolerance of ±1%, this component ensures stable reference voltages in demanding applications. Its low reverse leakage of 50 nA at 14.4V and a maximum impedance (Zzt) of 11 Ohms at 18V contribute to its high performance. The device is housed in a DO-204AL (DO-41) axial package, suitable for through-hole mounting and operation across a wide temperature range of -65°C to 175°C. This diode finds application in power supply regulation, voltage clamping, and surge protection circuits across various industrial sectors including telecommunications and automotive.
