1N5356B Zener Diode 18V 5W

The 1N5356B is a high power silicon oxide passivated Zener diode designed for voltage regulation and protection applications. It is part of the popular 1N53 series, which provides a wide range of Zener voltages with tight tolerances. With its 5 Watt rating, it can handle significantly higher currents than smaller 500 milliwatt or 1 Watt diodes, making it suitable for robust power supply designs. Housed in a DO-201 axial lead plastic package, this diode is built to withstand environmental stress while maintaining stable voltage characteristics. It is commonly used in industrial power supplies, automotive electronics, and surge suppression circuits where a stable 18 Volt reference or clamp is required under varying load conditions. The cathode is indicated by a color band on the body of the device.
