Junction capacitance is 10 pF at 10 V, 1 MHz — low enough that the diode does not load the switching node in a 1 MHz forward converter.","metaTitle":"1N6621US Microchip Fast Recovery Diode, 440V, 1.2A, SQ-MELF","metaDescription":"1N6621US from Microchip Technology: 440V, 1.2A fast recovery diode, 30 ns trr, SQ-MELF surface mount.
