HER302-T Discrete Semiconductor Products

HER302-T is a single rectifying diode, commonly known as a selenium rectifier. This device is primarily used for applications that require an efficient and effective way to rectify and regulate electrical currents. It is highly effective in power supply, sine wave filtering and control systems.

The HER302-T has a very low forward voltage drop, which is essential in low-voltage applications, as well as a reverse voltage of up to 200V. It also offers a low thermal resistance, making it ideal for power management applications. It is typically used in applications where thermal load must be kept low and the efficiency of the device must be high.

The working principle of HER302-T is quite simple. It is composed of a pair of back-to-back PN junctions (PNP and NPN) which allow the rectification of an alternating current. This is done by creating opposite potentials in the PNP and NPN regions.

The alternating current will then flow through the PN junctions of the diode, creating a unidirectional current flow, and thus allowing the rectification of the current. The current will also be regulated, as it will only be able to flow one way. This is the reason why it is often used in power supply and control systems.

The HER302-T is commonly used in the following applications:

• switched mode power supplies
• high power switching and motor control
• sine wave filtering and noise reduction
• loudspeakers, relays, and switching circuits
• AC-DC converters
• DC voltage regulation
• audio amplifiers

The HER302-T is a reliable and cost-effective device that can be used in a variety of applications. It is highly effective in applications that require a low forward voltage drop, high reverse voltage and low thermal resistance. The device also offers an efficient and effective way to regulate electrical currents.
