Overview
The SK14 is a surface-mount Schottky barrier rectifier housed in a standard SMA (DO-214AC) package. It is designed for low-voltage, high-frequency rectification and protection tasks, offering a maximum average rectified output current of 1A and a peak repetitive reverse voltage rating of 40V.
Why Choose This Part
The SK14 features a low forward voltage drop which minimizes power dissipation and improves efficiency in battery-powered devices. Its SMA package provides a compact footprint with a length of 5mm and a width of 2.7mm, suitable for space-constrained PCB layouts. Additionally, the device is rated for operation across a wide temperature range from -50C to +150C.
Applications
DC/DC Converter Output Rectification
Used as a catch diode in switching power supplies to provide a path for inductor current during the off-cycle.
Reverse Polarity Protection
Placed in series with DC power inputs to protect sensitive downstream circuitry from battery or supply reversal.
Freewheeling Diode
Suppresses inductive voltage spikes when switching inductive loads like small DC motors or relays.
