1N5819 Schottky Barrier Diode

The 1N5819 is a Schottky barrier diode prized for its low forward voltage drop and fast switching speed compared with standard rectifier diodes, making it a common choice in inverters and DC-DC converter circuits where switching efficiency matters. Its lower reverse breakdown voltage is a fair trade-off for the significant efficiency gains it offers.

With a forward voltage drop of just 600mV at 1A and a forward current rating of 1A, this diode minimises power loss during conduction, while its guard ring die construction offers protection against transient voltage spikes. Rated for a forward surge current of up to 25A and a reverse voltage of 28V RMS, the 1N5819 is well suited to polarity protection, current flow regulation, and low-voltage, high-frequency inverter applications.

• Low forward voltage drop – just 600mV at 1A for efficient conduction
• Fast switching speed – ideal for inverters and DC-DC converters
• 1A forward current – solid current handling for its size
• 25A forward surge current – strong surge tolerance
• Guard ring construction – built-in transient protection
• Common applications – polarity protection, current regulation, inverters
