SD51R

SD51R is a single-phase, fast rectifier diode. It is widely used in low power applications, such as switching regulators, motor drives, and AC/DC power conversion circuits.

The SD51R is a silicon epitaxial planar fast rectifier diode with an ultrafast recovery time. This device is designed for applications with an operating frequency up to 150 kHz, and it has a low forward voltage drop and a low reverse leakage current.

The fast-recovery power rectifier can be used as a rectifier diode or as a protection diode in power converter and power control circuits. It also can be used in high-frequency switching applications, such as for phase-shifted converters.

The SD51R is a three-terminal device consisting of a p-base layer, an n-base layer, and a common anode layer. The p-base layer is the anode and is connected to the positive voltage. The n-base layer is the cathode, and is connected to the negative voltage. The common anode layer acts as the gate. The gate voltage is used to control the forward voltage drop, reverse leakage current, and switching speed.

The SD51R has a high-current carrying capability and low resistance compared to other diodes. It can withstand transients up to 30 A, and has a breakdown voltage of 200 V. It is capable of generating up to 50 W of power with a 40 V forward voltage drop. The forward voltage drop increases slightly as the load current increases, which allows it to be used at lower voltages without loss of efficiency.

The SD51R has a fast recovery time, allowing it to be used in high frequency applications. It can switch from full conduction to full blocking in only a few microseconds, making it ideal for high frequency applications. The fast recovery time also limits the charge stored in the diode, which reduces ringing and improves stability.

The SD51R is also capable of withstanding high-temperature operation, making it suitable for use in harsh environments. It has a maximum operating temperature of 150°C. An optional cable kit is available for use in high-temperature applications.

The SD51R is a versatile fast rectifier diode that can be used in many low power applications. Its fast recovery time and low forward voltage drop make it ideal for high-frequency switching applications, and its high current capability and low resistance make it well suited for rectifiers and protection circuits.
