The 1N5819HW-7-F from Diodes Incorporated is a single Schottky barrier rectifier rated for 1A average rectified current and 40V peak repetitive reverse voltage. It is designed for general rectification applications including low-voltage high-frequency inverters, freewheeling circuits and polarity protection.
The device combines low forward-voltage drop, low power loss and high efficiency. Maximum forward voltage is specified at only 0.45V at 1A, helping reduce conduction losses and thermal dissipation in low-voltage power systems.
High surge capability is another key feature, with a 25A peak forward surge-current rating. Guard-ring die construction improves transient protection, making the device useful in power circuits exposed to startup surges or inductive switching events.
The device has a maximum reverse current specification of 1000µA at 40V and a total capacitance of approximately 50pF. These characteristics make it suitable for switching power supplies, DC/DC converters, battery-powered systems and general-purpose power rectification.
The 1N5819HW-7-F is supplied in a compact SOD123 surface-mount package. Diodes identifies the device as lead-free, fully RoHS compliant, halogen- and antimony-free. Its current Master CofC lists the exact 1N5819HW-7-F ordering code as Active with matte-tin terminals.
For automotive designs, Diodes specifies a separate 1N5819HWQ version. The requested 1N5819HW-7-F is the standard version and should not be marketed as the dedicated automotive-qualified part.
