The 1N5313 BK part from Central Semiconductor is a single diode with a Glass Passivated Die construction in a SOD-323 flat leaded package. It is an ultra-fast switching diode rated for a peak reverse voltage of 100 V and a maximum forward current of 200 mA. The 1N5313 BK has a ultra-fast switching speed of 1.5 nanoseconds and a maximum repetitive reverse voltage of 70 V. This makes it suitable for use in high speed switching applications, such as circuit protection, high speed switching, and signal conditioning. The 1N5313 BK is also RoHS compliant, making it a good option for applications that require restricted hazardous substances.
