Frequently Asked Questions (FAQ)
Q: What is the switching speed of the 1N4148 diode?
A: The reverse recovery time of the 1N4148 diode is extremely fast at 4 nanoseconds, making it ideal for high-frequency switching applications.
Q: Which side of the 1N4148 diode is the cathode?
A: The cathode is indicated by the black or colored band printed on one end of the glass body of the diode.
Q: Can I use the 1N4148 diode as a replacement for the 1N4007?
A: No, you should not use the 1N4148 as a direct replacement for the 1N4007 in power supply rectification because the 1N4148 is rated for only 200mA, whereas the 1N4007 handles up to 1A.
