A diode is a device that allows current to move in only one direction, from the anode to the cathode. The 1N4148 diode is designed for fast switching, meaning it can quickly turn on and off when controlling current flow. This makes it very useful in circuits that need high-speed switching. The cathode of the 1N4148 can be easily recognized by a grey bar. It can handle up to 300mA of continuous current and withstand peaks as high as 2A, making it a good choice for circuits that require fast performance. The diode’s fast recovery time, which is just 8 nanoseconds when running at 10mA of forward current, is what sets it apart for use in fast-switching applications.
The 1N4001 diode is often used in circuits to block current from flowing in the wrong direction, which helps protect the sensitive parts of your electronics. This diode is great for general use in power applications where you need to make sure electricity flows in only one direction. The 1N4001 also helps with preventing damage caused by things like reverse polarity or spikes from devices like motors or relays. It has a voltage drop of about 0.7V when current flows through it, and it can safely carry a continuous current of 1A. The diode is also strong enough to protect against reverse voltages of up to 50V. If you're looking for more technical details, you can refer to its datasheet for additional information.

Either of these diodes should work, but the 1N4001 is a better choice because it is the "bigger" device: the 1N4001 is a 1-amp rectifier, whereas the 1N4148 is a 100mA small signal device. For small relays, it's fine. The 1N4148 is another option for applications where fast recovery time is needed, such as logic speed signals. The decision depends on your application. Use the 1N4148 for fast switching and lower currents, while the 1N4001 is ideal for higher current rectification.
