The 1N4001 series (or 1N4000 series〔Though some writers and datasheets refer to "1N4000 series", a 1N4000 is a 10-watt Zener diode unrelated to the 1N4001 series of 1 ampere rectifiers.〕) 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.〔(Diodes: 1N4001 - 1N4007 datasheet )〕 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.〔 (【引用サイトリンク】 Axial Discretes )〕 These are fairly low-speed rectifier diodes, being inefficient for square waves of more than 15 kHz. 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.〔(Motorola Silicon Rectifier Handbook ) 1966.〕 The 1N5400 series were announced in ''Electrical Design News'' in 1968, along with the now lesser known 1.5 A 1N5391 series.〔(Electrical Design News ), Volume 13, 1968〕 These devices are widely used and recommended.〔 〕〔 〕〔 〕 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. ==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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1N4001 and 1N5400 series diodes」の詳細全文を読む スポンサード リンク
