Diodes - Rectifiers - Single

SMD22PL-TP is a three-pin surface-mounted Schottky diode rectifier, featuring a low forward voltage drop, soft-recovery characteristics and a compact size. It has a reverse peak power dissipation of 20W and a maximum forward voltage of 350V. This diode rectifier is suitable for a wide range of applications such as in the protection of AC line surge, DC/DC converters, switching power supply and DC-AC inverters.

Application Field and Working Principle

The SMD22PL-TP offers fast recovery from high-energy surge currents, making it suitable for rectification of alternating and direct current (AC/DC) power in inverters and chargers. It also features an in-circuit current limit, which allows for high surge currents to the load without damage to the semiconductor device, making it ideal for use in security systems, LED lighting and automotive electronic systems. The device can be used in both unipolar and bipolar applications, providing protection against reverse over-voltage and providing a low forward voltage drop.

The working principle of SMD22PL-TP can be explained as follows. When forward-biased, due to the low forward voltage drop, current flows freely through the semiconductor device, allowing power to pass through the load. If a reverse voltage is applied to the device, it limits the current flow to protect the load from overcurrent and reverse current damage. It then allows current to pass through the load again only if the voltage is taken back to its nominal forward state. This ensures that the load is protected from damage and continues to operate correctly.

The SMD22PL-TP is also suitable for power-supply applications, such as in switching power supplies and DC-AC inverters, due to its low forward voltage drop and soft-recovery characteristics. It also features a fast switching time, which ensures that the load is protected from overcurrent during transient periods while providing high power efficiency.

In addition, the SMD22PL-TP is also suitable for protection against AC line surge, as it can absorb large amounts of energy in a short period of time, thus preventing damage to the load. It is also ideal for use in automotive electronic systems, as it can protect against reverse voltages.

Overall, the SMD22PL-TP is capable of providing efficient power management in various electronic systems. Its low forward voltage drop and fast switching time ensure that it can provide effective protection against current and voltage overloads, while its soft-recovery characteristics ensure that it can handle high surge currents without damage to the load.
