1N3273R

The 1N3273R is a single, high voltage, fast recovery rectifier diode. It is used primarily in applications such as high voltage Shottky diodes and polarity protection where it provides fast recovery times when switching in reverse bias.

The 1N3273R is a switched mode power supply rectifier that is capable of handling high current loads up to 100A. The device has low forward voltage drops and low leakage current characteristics, making it a good choice for applications requiring very high efficiency. Typical applications include power conversion, invertor feedback systems, guidance systems, high frequency inverter output stages, ripple noise reduction, and switching diode clamps used in power electronics.

The 1N3273R has a maximum operating temperature of +175°C and an average junction temperature of +150°C. Its forward voltage drop is typically 8V and its reverse leakage current is typically very low. The device is offered in surface mount and through-hole package styles for easy integration into existing circuit boards. It is commonly used in motor control circuits, UPS systems, DC/DC converters, switch mode power supplies, and other high voltage applications.

When used in forward bias, the 1N3273R operates by allowing electrons to flow through the P-type layer from EM junction to the N-type layer. This flow of electrons generates a voltage drop across the diode. The reverse bias operation of the diode is achieved by allowing electrons to flow from the N-type layer through the EM junction to the P-type layer to create the opposite voltage drop. The device has a fast recovery time, typically within 1-2 nanoseconds, which is ideal for applications requiring high speed switching rates.

In general, the 1N3273R is a high voltage, fast recovery rectifier diode that is well suited for high current applications such as motor control, power conversion, and power distribution. It is available in both surface mount and through-hole packages, is suitable for temperatures up to +175°C, and has a low forward voltage drop of 8V and low leakage current characteristics. The device is capable of switching in reverse bias in 1-2 nanoseconds, making it an ideal choice for high speed switching applications.
