Like all PN-junction diodes, it allows current to flow in one direction (from anode to cathode) when forward biased above its threshold voltage (~0.7V) and blocks current flow when reverse biased up to its rated breakdown voltage of 100V.\u003c\/p\u003e\n\u003cp\u003eWhat distinguishes the 1N4148 from standard rectifier diodes (such as the 1N4007) is its extremely fast reverse recovery time. When a diode switches from conducting (forward bias) to blocking (reverse bias), there is a brief moment where reverse current flows as stored charge in the junction is depleted. The 1N4148 accomplishes this transition in under 4 nanoseconds, making it suitable for circuits operating at frequencies well into the MHz range.\u003c\/p\u003e\n\u003cp\u003eThe black band printed on the glass body indicates the cathode terminal. Current flows from anode to cathode in normal forward-biased operation. When reading a schematic, the cathode corresponds to the bar side of the diode triangle symbol.\u003c\/p\u003e\n\n\u003ch2\u003eProject Ideas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eFlyback \/ Freewheeling Diode for Relays \u0026amp; Motors\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eProducts ship within 1-5 days from our Bengaluru warehouse.
