Microchip Technology's 1N4471-TR is an 18V Zener diode with a robust 1.5W power rating and a ±5% voltage tolerance. Designed for applications requiring precise voltage regulation, this component features a low reverse leakage of 50 nA at 14.4V and a maximum Zener impedance of 11 Ohms. The axial-leaded DO-41 (DO-204AL) package is suitable for through-hole mounting, facilitating integration into various circuit designs. Operating across a wide temperature range of -65°C to 175°C, the 1N4471-TR is well-suited for demanding environments. Its forward voltage is rated at a maximum of 1.5V at 1A. This device finds application in power supply regulation, voltage clamping, and signal conditioning within industrial, automotive, and consumer electronics sectors. The TR designation indicates packaging on tape and reel for automated assembly.
