Frequently Asked Questions
1.What is 1N4003?
The 1N4003 is a general-purpose silicon Rectifier Diode, designed for low power and switching applications.
2.How to safely long run 1N4003 in a circuit?
To increase the usage life of 1N4003 diode it is suggested to not drive a load of more than 200V, do not drive more than 1A or 1000mA load, and always store or use the diode in temperature between -55 degrees centigrade to +175 degrees centigrade.
3.What is the difference between 1N4003 and 1N4007?
The main difference is the peak reverse voltage rating (there are other somewhat subtle differences). If you are absolutely certain that more than 200 VDC reverse bias is impossible in the circuit you can almost certainly use a 1N4003. The peak reverse voltage of 1N4007 is 1000 V.
