1N5819HW-7-F
Category
The 1N5819HW-7-F Schottky diode provides efficient rectification with 450mV forward voltage at 1A, suitable for low-voltage DC systems. Its 40V reverse rating and SOD-123 package make it ideal for compact consumer electronics and battery systems. Critical design considerations include thermal management, soldering profiles below 260°C, and protection against overvoltage conditions. The device's strengths in low-loss conversion and ESD resilience are balanced by thermal limitations and moderate cost positioning in the Schottky diode market.
