The SB350-E3/73 is a rectifier diode belonging to the line of power rectifiers offered by Vishay Intertechnology. This diode is suited for a wide variety of applications, ranging from power supply rectification to motor control. As part of the line of silicon power rectifiers, the SB350-E3/73 is designed to be used in a variety of applications, though the design of the part is specifically intended to meet the needs of products and systems in the medical, industrial and consumer markets.

As a single rectifier diode, the SB350-E3/73 offer resistance to reverse overloads and reverse voltages up to 125V. Each diode is given allowances for thermal, overload and reverse voltages, so as to ensure that the part can take what is needed, in the environments in which it is placed. The maximum repetitive peak reverse voltage (VRRM) for the SB350-E3/73 is given at 190V, while the maximum average forward rectified current (IO) is allowed for continuous operation at 15.8A.

The SB350-E3/73 has a junction temperature range between - 65 °C and 150 °C. The thermal resistance junction to case (RthJC) for the SB350-E3/73 is extremely low at 0.45°C/W, gives the parts its significant level of durability. This also helps protect from thermal stress and potentially dangerous situations. The diode is also given storage temperatures between -40°C and 150°C. This single rectifier diode was released in early 2016, and is IEC61646-1 and IEC-61646-3 certified, sets market trends with its compact size and low energy transfer.

The SB350-E3/73 is designed to handle voltage applications up to 190V, with current up to 15.8A. It features a low thermal resistance junction to case, and provides maximum temperature protection while transferring less energy. This diode can be used as a very durable and reliable direct conversion in a wide variety of application; from motor control, power supply rectification, current control, and critical signal protection. It is also made from lead-free material and meets RoHS requirements.

The SB350-E3/73 offers multiple advantages for the consumer including: a low package size for the number of pins (0.050 inch spacing between leads), a low thermal resistance junction to case, excellent reverse voltage capabilities, and a low forward voltage drop (0.57V @ IF = 8 A). This diode also offers lower power consumption, good temperature cycling characteristics, and a very good power factor. It also offers protection from overloads and reverse voltage.

The working principle of the SB350-E3/73 is quite simple. The diode consists of two terminals, one anode and one cathode. When the anode is connected to the positive terminal of an AC power supply and the cathode to the negative terminal, current will flow in the forward direction. However, when the terminals are reversed, no current will be able to flow as the diode will be in its reverse-biased condition.

In conclusion, the SB350-E3/73 is an ideal rectifier diode for critical signal protection and motor control. The well-designed package and low thermal resistance junction to case makes this diode well suited for such applications. Thanks to its low voltage and current requirements, it can be used for direct conversion in almost any environment. The SB350-E3/73 is an excellent choice for today’s system; and is perfect for a wide range of applications, from motor control and power supply to current control and critical signal protection.
