Categories: Single Diodes
Quality Control: Learn More
Microchip Technology's 1N4944 is a fast-recovery general-purpose diode featuring a 400V reverse voltage rating and 1A forward current capability. This through-hole component, packaged in an axial lead configuration (A, Axial), exhibits a maximum forward voltage drop of 1.3V at 1A and a reverse leakage current of just 1 µA at 400V. Its reverse recovery time (trr) is specified at 150 ns, classifying it as a fast recovery diode. The device operates across a junction temperature range of -65°C to 175°C and has a capacitance of 35pF at 12V and 1MHz. The 1N4944 is commonly utilized in power supply rectification, switching circuits, and general industrial applications.
