Frequently Asked Questions

What are the key electrical specifications of the 1N5819HW-7-F?

The 1N5819HW-7-F is a Schottky rectifier diode with a maximum reverse voltage of 40V, forward current of 1A, and low forward voltage drop typically around 0.35V at 1A. It features silicon construction in a 2-pin SOD-123 SMT package.

What applications is the 1N5819HW-7-F suitable for?

This diode is ideal for general-purpose rectification, reverse polarity protection, freewheeling in DC-DC converters, battery management circuits, and power supply designs. Its low power loss makes it especially effective in portable and battery-powered devices requiring high efficiency.

What package does the 1N5819HW-7-F use and how does it compare to through-hole alternatives?

The 1N5819HW-7-F uses the SOD-123 surface-mount package, which is significantly smaller than through-hole DO-41 alternatives. The -7-F suffix indicates it meets specific tape and reel packaging requirements from Diodes Incorporated, making it compatible with automated SMT assembly processes.

Are there compatible replacement parts for the 1N5819HW-7-F?

Compatible alternatives include the SS14 (40V 1A SMA), 1N5819 (DO-41 through-hole), and MBRS140 with similar ratings. When substituting, verify the package footprint, reverse voltage (40V), forward current (1A), and forward voltage drop specifications match your design requirements.
