## Description
The 1N5819HW-7-F from Multicomp Pro is a surface-mount Schottky barrier diode utilizing majority carrier conduction to deliver extremely low forward voltage drop and minimal stored charge. Housed in a compact, 2-pin SOD-123 plastic package, this 1 A rectifier is engineered for high-efficiency power management applications where minimal conduction and switching losses are paramount. It features a maximum repetitive peak reverse voltage ($V_{RRM}$) and DC reverse voltage ($V_R$) of 40 V, a non-repetitive peak reverse voltage ($V_{RSM}$) of 48 V, and an average rectified output current ($I_O$) of 1 A at a junction temperature of 25°C. With a peak forward surge current ($I_{FSM}$) rating of 25 A for an 8.3 ms half-sine wave, the device effectively handles transient overcurrent conditions in dense circuit layouts.
Electrical characteristics include a maximum forward voltage ($V_F$) of 0.6 V at 1 A and 0.9 V at 3 A, alongside a controlled reverse leakage current ($I_R$) of 1 mA at the rated 40 V reverse voltage. The diode exhibits a typical junction capacitance ($C_D$) of 120 pF at 4 V and 1 MHz, supporting high-frequency operation while limiting reactive losses. Designed for continuous operation within a junction and storage temperature range of -65°C to +125°C, the component features a thermal resistance junction-to-ambient ($R_{\theta JA}$) of 80°C/W and a power dissipation ($P_d$) limit of 250 mW.
This Schottky rectifier is ideally suited for deployment in low-voltage, high-frequency inverters, free-wheeling diode configurations, and DC-DC power conversion topologies requiring reverse polarity protection. Supplied on a full tape and reel packaging format of 3,000 units, the 1N5819HW-7-F facilitates automated pick-and-place assembly for high-density surface-mount printed circuit board manufacturing.
