1N400x general-purpose diodes
The 1N4001 series (or 1N4000 series[2]) is a family of popular 1.0 A (ampere) general-purpose silicon rectifier diodes commonly used in AC adapters for common household appliances. Blocking voltage varies from 50 to 1000 volts. This diode is made in an axial-lead DO-41 plastic package.[3]
The 1N5400 series is a similarly popular series for higher current applications, up to 3 A. These diodes come in the larger DO-201 axial package.[4]
Overview
These are fairly low-speed rectifier diodes, being inefficient for square waves of more than 15 kHz.[5] The series was second sourced by many manufacturers. The 1N4000 series were in the Motorola Silicon Rectifier Handbook in 1966, as replacements for 1N2609 through 1N2617.[6] The 1N5400 series were announced in Electrical Design News in 1968, along with the now lesser known 1.5 A 1N5391 series.[7]
These devices are widely used and recommended.[8][9][10]
The table below shows the maximum repetitive reverse blocking voltages of each of the members of the 1N4000 and 1N5400 series.

|---|---|---|---|---|

In the version of these components manufactured for Fairchild Semiconductor in Suzhou, the silicon chip that rectifies the current weighs just 880 micrograms.[14][15][16][17]
Nonstandard uses
Many of the diodes in this family exhibit a change in capacitance with reverse bias and can thus be used by experimenters as makeshift varicap diodes.
