Package:

The MMBD914LT1G typically comes in the SOD-323 package, which is a small, surface-mount package.

Pinout and Function Specification:

The MMBD914LT1G comes in a 2-pin configuration (not 200 pins). Here are the details of the pins:

Pin Number Pin Name Pin Function 1 Anode The anode pin, connected to the positive voltage or signal input. 2 Cathode The cathode pin, connected to the negative voltage or signal output.

Detailed Explanation of Pin Functions:

Pin 1 (Anode): The anode is the positive side of the diode. It is the point where the current enters the diode in the forward-biased condition. For the diode to conduct, the voltage at the anode must be greater than the voltage at the cathode by at least the forward voltage (typically 0.7V for silicon diodes like the MMBD914LT1G). This pin is typically connected to a signal line or the higher voltage side of a circuit. Pin 2 (Cathode): The cathode is the negative side of the diode. It is the point where the current exits the diode in the forward-biased condition. The diode will block current flow in reverse bias unless the reverse voltage exceeds the breakdown voltage, at which point it might break down. The cathode pin is connected to the output of a signal or lower voltage side in a circuit.
