1N4148 Frequently Asked Questions (FAQ)
-
The recommended storage temperature for 1N4148 diodes is -40°C to 125°C, as per Vishay's storage and handling guidelines.
-
While the 1N4148 is a general-purpose diode, it's not ideal for high-frequency applications due to its relatively high capacitance (4pF) and inductance. For high-frequency applications, consider using a diode with lower capacitance and inductance, such as the 1N4146 or 1N916.
-
The 1N4148 diode has a maximum reverse voltage rating of 100V, which may not be sufficient for high-voltage applications. If you need a diode for high-voltage applications, consider using a diode with a higher voltage rating, such as the 1N4007 or 1N5399.
-
While the 1N4148 diode can be used in switching power supplies, its relatively high reverse recovery time (4ns) may not be suitable for high-frequency switching applications. Consider using a diode with a faster reverse recovery time, such as the 1N4146 or 1N4937, for switching power supply applications.
-
Yes, the 1N4148 diode made by Vishay Semiconductors is RoHS (Restriction of Hazardous Substances) compliant, meaning it meets the EU's directive on the restriction of certain hazardous substances in electrical and electronic equipment.
