1N5820RLG Description

Short technical summary and product information.

The 1N5820RLG is a Schottky barrier rectifier from On Semiconductor, designed for low-voltage, high-frequency applications. It is rated for a peak repetitive reverse voltage of 20V and an average rectified forward current of 3A. The forward voltage drop is typically 475mV at 3A, enabling low power loss and high efficiency. The device features fast recovery with less than 500ns switching time at currents above 200mA. It is housed in a DO-201AD (DO-27, Axial) through-hole package with a weight of approximately 1.1 grams. The operating junction temperature range is -65°C to 125°C. Non-repetitive peak surge current is 80A, and thermal resistance (junction-to-ambient) is 28°C/W. This rectifier is ideal for use in inverters, freewheeling diodes, and polarity protection circuits. It is available in tape and reel packaging with 1500 units per reel, and lead-free packages are available.
