BA159 fast recovery silicon rectifier diode 1.0A 1000V for LED driver
Description:
Ultra Fast Recovery Rectifier Diode is a semiconductor device which possesses short reverse recovery time for rectification purpose at high frequency. A quick recovery time is crucial for rectification of high-frequency AC signal. Diodes are mostly used in rectifiers because they possess ultra-high switching speed.
The fast recovery diode is constructed in the similar manner by which ordinary diode is constructed. The major difference in construction between these diodes and conventional diodes is the presence of recombination centres. In fast recovery diodes, Gold (Au) is added to the semiconductor material. This leads to augmentation in the numerical value of recombination centres due to which the lifetime (?) of charge carriers decreases.
Features:
• Diffused junction
• Fast switching for high efficiency
• High current capability and low forward voltage drop
• Surge overload rating to 30A peak
• Low reverse leakage current
• Plastic material has UL flammability classification 94V-0
Advantages of Fast Recovery Diode:
• Ultrahigh Switching Speed
• Low reverse recovery time
• Improved efficiency as compared to conventional diodes.
• Reduced loss
