The maximum forward current of the diode is 125mA and the temperature range of the diode is -65°c to +175°c.

The lead spacing of 1N4148WTR is 3.2mm with 0.45mm height. 1N4148WTR has extremely small physical dimension and the weight of the diode is just 0.0117g. The diode has high stability and resistance to electrical noise. The diode is designed with a very thin conductor strip, that reduces power loss due to its very low resistance.

1N4148WTR is a single diode and it is used in a wide range of electronic circuits. Its most common application is to protect the circuit from various transient voltage spikes due to its very fast switching ability. It can also be used to regulate the current in a particular circuit by limiting the electrical flow direction in the circuit. It is also used as a switch to control the current flow in the circuit.

The working principle of 1N4148WTR is quite simple. It consists of two terminals, anode and cathode. When a positive voltage is applied to the anode, the diode becomes forward biased and electrons start to flow from anode to the cathode. This current flow is limited to a specific amount and the diode acts as a low resistance path for current flow. But when a negative voltage is applied to the anode, the diode becomes reverse biased and electrons start flowing from cathode to anode. This current flow is known as blocking current and it is limited to few micro-amps.

Apart from its use in general electronic circuits, 1N4148WTR can also be used in computer systems, telecommunications devices, automotive electronics, gaming consoles and various other electronic systems. The diode is used in circuit protection, current regulation, voltage regulation, signal and power switching, signal modulation and circuit isolation. 1N4148WTR is also used in devices that run on high frequency and require improved heat dissipation.

1N4148WTR is a reliable and efficient diode with low manufacturing cost. The diode offers enhanced performance, minimum power loss and high blocking capability. It is suitable for various high-speed and low-loss applications, and its very small size and weight make it ideal for high-density circuits and assemblies.
