UF4004 is a general fast recovery diode. Its main parameters are as follows:

  • Maximum reverse voltage (Peak Reverse Voltage, PRV): 400V
  • Maximum forward current (Peak Forward Current): 1A
  • Maximum forward voltage drop (Maximum Forward Voltage Drop): 1.1V @ 1A
  • Maximum reverse current (Maximum Reverse Current): 10μA @ 25°C, 500μA @ 100°C
  • Maximum reverse recovery time (Maximum Reverse Recovery Time): 75ns
  • Operating temperature range (Operating Temperature Range): -55°C to +150°C
  • Package type: DO-41

These parameters make the UF4004 suitable for a variety of applications requiring fast switching and high voltage tolerance, such as power converters and power rectification.

Applications

  • Power Rectification: UF4004 can be used in the rectifier bridge in the power converter to convert AC to DC. Due to its fast recovery time, UF4004 is particularly suitable for high-frequency switching power supply applications.
  • Voltage Protection: UF4004 can be used to absorb voltage spikes that may cause damage to the circuit. For example, it can be used for reverse protection of power lines or data lines to prevent reverse connection of power or signals.
  • Pulse Generation: In pulse generators or timing circuits, UF4004 can be used to quickly switch circuit states and generate precise pulses or waveforms.
  • Motor Control: In motor drive circuits, UF4004 can be used to eliminate the reverse electromotive force (EMF) generated when the motor is switched to prevent damage to the drive circuit.

These are just some typical applications for the UF4004 diode, and actual applications may vary depending on specific circuit design and needs. When designing a circuit, the electrical characteristics and performance requirements of the diode should always be taken into account.
