Description
High Current (1A), Ultra-High Surge (50A), Ultra-Compact Body (Φ5×9mm) – The Smallest High Power High Voltage Rectifier
The BR-F Series from HVRTION is a breakthrough family of fast recovery high voltage diodes designed for applications that demand high forward current (up to 1A), extremely high surge capability (50A), fast switching (150ns), and an ultra-compact package (Φ5×9mm). Covering a voltage range from 2KV to 10KV, these diodes deliver outstanding performance in power-dense systems where board space is at a premium. With a very low forward voltage drop (as low as 9V at 1A), ultra-low leakage (5µA at 25°C), and a remarkable 50A surge rating, the BR-F series is the ideal choice for miniaturized high voltage power supplies, portable medical devices, pulsed lasers, and industrial equipment.
