1N4148 VS 1N4007[FAQ]: What are the differences between them?

A diode is a semiconductor device that allows only one direction of current to flow. The current has to flow from the anode to the cathode at all times. The cathode terminal can be identified by a grey bar, as shown in the image above.

The IN4148 Diode has a maximum current carrying capacity of 300mA and can withstand peaks of up to 2A. This diode is used in applications that demand fast switching because of its fast recovery time of 8ns at a forward current of 10mA.

A diode is a semiconductor device that only enables current to flow in one direction. The current must always flow from the anode to the cathode. A grey bar, as illustrated in the image above, can be used to identify the cathode terminal.

The maximum current carrying capacity of the 1N4007 Diode is 1A, and it can withstand peaks of up to 30A. As a result, we can utilize it in circuits that use less than 1A. The reverse current is minimal at 5uA. This diode's power dissipation is 3W.

IN4148 is typically utilized in low-current inductive loads like buzzers and other low-current inductive loads. However, 1N4007 is commonly used in large current loads, such as industrial loads (relays), and power supply loads. The biggest difference between them is the current, voltage, and response speed. With a voltage of 100V and a current of 150mA, the 1N4148 is a switching diode. It has an nS level and a quick reverse recovery speed. The 1N4007 is a popular rectifier diode that can tolerate 1000V, 1A current, and has a reverse recovery time of uS. It is only suitable for use in low-frequency circuits.

From the point of my view, 1N4007 can replace 1N4148 as long as the response speed isn't too high. 1N4148 is only suitable for low-current inductive loads with a weak current. So if you want to replace 1N4148 with the 1N4007, please pay more attention to the response speed.
