Diodes - Bridge Rectifiers are essential building blocks in many electronic circuits. They are used to convert alternating current (AC) power into direct current (DC) power. The KMB24STR application field and working principle fall under this category.

A KMB24STR rectifier is most commonly used in applications requiring a transformer-isolated, full-wave rectifier. It is utilized to convert an AC voltage (up to 400 Volts) into a DC voltage. The KMB24STR rectifier is ideal for use in AC/DC power supplies, low-voltage DC power supplies, high-efficiency drives, and automotive applications. This product is housed in a four-pin thru-hole SIP package and it is RoHS compliant.

The KMB24STR rectifier offers a variety of benefits compared to other rectifier solutions. These include high efficiency and power, low power consumption, and long term stability. The KMB24STR rectifier has a low forward voltage drop (VF) of 0.81 and low reverse leakage current (IR) of 10 ma . Additionally, its speed of switching from on to off (TRR) is 10 ns, and its reverse recovery time (tRR) is also 10 ns. All of these features help to reduce the energy lost during switching, helping to maintain the rectifier\'s power and efficiency.

The working principle of the KMB24STR rectifier is fairly simple. The four isolated diodes are arranged in a full-wave rectifier bridge configuration. This allows for rectification of both positive and negative half-cycles of the input AC voltage. The rectified DC output voltage has two levels; one is positive and the other is negative. The amplitude of the DC output voltage is determined by the input AC voltage and the diode\'s characteristics.

The KMB24STR rectifier operates by the four diodes in the bridge acting as switches. When the input AC voltage reaches either positive or negative peak level, the corresponding diode is turned on and conducts electricity. This effectively converts the peak AC voltage into a direct current. The other two diodes are turned off, so the current alternates direction every cycle. This process is repeated for each half-cycle of the AC voltage, resulting in a pulsed DC voltage.

In addition to providing a rectified input voltage, the KMB24STR rectifier also includes a surge suppression element. This element is able to eliminate any surge voltages that may occur in the input and therefore keep the output voltage stable. This provides for more regulated power and can be beneficial in more sensitive applications, such as medical and communications equipment.

The KMB24STR rectifier provides a cost-effective alternative to more expensive solutions. It is small, robust, and available in a variety of configurations. Furthermore, it offers long lasting reliability, wide input voltage range, and high efficiency. These features make it an ideal choice for a range of applications where AC/DC power is needed and high efficiency is desirable.
