1N3261R Application Field and Working Principle

1N3261R rectifier diodes are general purpose standard 1A rectifiers with a maximum working voltage of 60V. These single-phase, standard diode rectifiers are manufactured in a DO-204AH (DO-35 case) package and offer robust performance in general-purpose, commercial, industrial and military applications.

Ideal for voltage conversion, DC power supply applications, such as full-wave rectification, bridge rectification, and phase control switching, 1N3261R diodes are a popular choice for both commercial and hobbyist projects. The 1N3261R rectifier diodes feature a low forward voltage drop and a fast recovery time for efficient buffering, signal protection, and energy saving.

When direct current passes through the anode of the 1N3261R, the diode area allows a single and direct flow-through of the electrical current. If a positive potential is applied to the anode and a negative potential to the cathode, the electrical current will flow from the anode to the cathode, allowing the positive potential to pass to the positive terminal of the device, while the negative potential passes through to the negative terminal. The device prevents any reverse current flow, thereby creating a rectifier effect, which can be used to regulate the voltage in electronic circuits.

The 1N3261R diode can handle high-frequency switching applications, as well as thermal, mechanical and electrical stresses, thanks to its high breakdown voltage and surge current capabilities. As such, it is suitable for high-power applications, such as high-voltage AC-DC conversions, DC-DC converters, AC power switch controls, and inverters. Other applications for which the 1N3261R is suitable include free wheeling diode circuits, high-frequency magnetronic circuits, rectification and protection in AC power systems, and power sensing circuits.

The surge forward current rating of the 1N3261R is 1A and its reverse current leakage is a maximum of 25 nA at a reverse voltage of 1.5 V. It is available in a DO-204AH package with a 100 mA (DC) power rating, and its maximum repetitive peak reverse voltage is 60V.

In summary, the 1N3261R diode rectifier is a general purpose, single-phase rectifier sold in a DO-204AH package. It is well-suited for commercial, hobbyist and industrial applications and offers excellent thermal, mechanical and electrical stress ratings. It is commonly used for voltage conversion, as a free wheeling diode circuit, in rectification and protection AC power systems, and in high frequency magnetronic applications.
