1N5818 Description

Short technical summary and product information.

The 1N5818 is a Schottky barrier rectifier from ON Semiconductor, designed for low-voltage, high-frequency applications. It offers a peak repetitive reverse voltage of 30V and an average rectified forward current of 1A. Forward voltage is typically 550mV at 1A, minimizing power loss. The device can handle non-repetitive peak surge currents up to 25A.

 

The rectifier is housed in a DO-41 (DO-204AL) axial lead package intended for through-hole mounting. It operates over a junction temperature range of -65°C to +125°C with a thermal resistance of 80°C/W. The cathode is identified by a polarity band. ESD ratings are Machine Model C (>400V) and Human Body Model 3B (>8000V). This device is Pb-free as verified by the datasheet and suitable for use in rectification, freewheeling diodes, and polarity protection circuits.
