Pin Function Specifications and Circuit Principle Instructions
The 1N4148WS-7-F comes in a SOD-323 package, which is a small surface-mount package. It has 2 pins.
Pin Number Pin Name Pin Function 1 Anode The input terminal for the current flow into the diode. This is where the positive voltage is applied when the diode is forward biased. 2 Cathode The output terminal for the current flow out of the diode. This pin is connected to the more negative side of the circuit, where the diode blocks current in reverse bias.Circuit Principle
The 1N4148W S-7-F is a PN-junction diode with a fast switching characteristic. The main purpose of the diode is to allow current to flow in one direction (forward bias) and block current flow in the opposite direction (reverse bias). It’s typically used for signal processing, high-frequency circuits, and digital logic.
Forward Bias Operation: When the Anode is at a higher voltage than the Cathode, the diode conducts current with low resistance. Reverse Bias Operation: When the Cathode is at a higher voltage than the Anode, the diode blocks the current and prevents any significant flow.20 Common FAQs for the 1N4148WS-7-F
