The ACGRA4003-HF has a peak reverse recovery time of 4.5ns, a junction capacitance of 5.3pF, a minimum thermal resistance of 300C/W, and a maximum operating temperature of 175C.

Application Field

The ACGRA4003-HF is a commonly used diode in high frequency rectifier applications. It is suitable for high current rectification, high voltage power supplies, RF power supplies, switching power supplies, and other applications where fast recovery of a high current is required. The low forward voltage drop of the ACGRA4003-HF makes it useful for high frequency applications, such as those involving high frequency switching, variable frequency motor controls, telecom and medical equipment, industrial equipment, computers, and so on.

Working Principle

The ACGRA4003-HF is a rectifier with a forward voltage drop of only 0.44V at 1A, making it the ideal choice for high frequency rectifier applications. It works on the principle of a reverse-conducting diode. When a voltage is applied to the diode in the reverse direction, the diode conducts current in reverse. This reverse current slowly charges up the junction capacitance, until the diode can no longer support the current. At this point, the diode switches to a forward-conducting state and allows current to flow through the circuit in the opposite direction. As the current flows through the circuit, the charge in the junction capacitance is released, thus allowing the device to recover very quickly. The ACGRA4003-HF has a peak recovery time of 4.5 ns. This makes it the perfect choice for high-frequency applications, as it can switch from a reverse-conducting state to a forward-conducting state very quickly.

Conclusion

The ACGRA4003-HF is a fast recovery rectifier diode that is suitable for high frequency rectifier applications. Its low forward voltage drop and high peak reverse recovery time make it ideal for high frequency switching applications and other devices that require fast recovery of a high current. This diode is a good choice for applications that require high current, high forward surge capability, and low forward voltage drop.
