1N4001 Equivalent

This is a table of equivalent models of 1N4001, they are all rectifier diodes. The main function is to convert AC power to DC power, and the role of the protection circuit.

Picture	Name	Makers	Recovery Time	Maximum Current	Maximum Voltage	Package Type
	1N4001	ON Semiconductor	<2µs	1A	50V	DO-41
	BA159	STMicroelectronics	≤500ns	1A	100V	DO-41
	ES1D	Vishay	≤50ns	1A	100V	SMD
	FR101	Vishay	≤500ns	1A	100V	DO-41
	HER102	Diodes Incorporated	≤75ns	1A	100V	DO-41
	UF4001	ON Semiconductor	≤30ns	1A	50V	DO-41

Note: In this table, UF4001 is the most suitable replacement for 1N4001, all other parameters match with 1N4001, and the recovery time is faster than 1N4001. BA159, FR101 and HER102 have higher max voltage, max current, and they are suitable for replacing 1N4001 as well. If you use ES1D to replace them, the parameters are all in line, but the package type is different, which may lead to problems in installation.
