The BAS21PGX rectifying diode array is a solid state polarity protection device designed to protect sensitive electrical components from damage or misoperations due to reverse polarity connection. It is a 3-pin dual diode array package, consisting of two non-isolated, NPN matched silicon diodes, combined for use in applications that require reverse polarity protection.

The BAS21PGX rectifying diode array is specifically designed to protect from reverse-polarity connection, eliminating the need for physical blocking diodes or the use of a diode bridge circuit. With its integrated design, the BAS21PGX requires less space, reduces the number of components, and is less expensive to implement than a bridge circuit or blocking diodes.

Using the standard industry mounting practices, the BAS21PGX can be securely mounted onto almost any application boards. In addition, the device has several features, such as an input voltage range of 4.5V to 30V, a storage temperature range of -55° to +175°C, and surge ratings of 10A at 10ms, which makes the BAS21PGX suitable for a wide range of applications.

The working principle of the BAS21PGX rectifying diode array is simple; it simply prevents current from flowing in the wrong direction. Once the impulse voltage reaches a certain level, the negative half-cycle switches the diodes so that the positive potential is blocked, thus preventing current from crossing into the wrong direction. When the voltage reverses and the positive potential is below the breakover voltage, the protection is over and the array switches off.

The BAS21PGX rectifying diode array is commonly used in automotive or transportation applications, such as in-vehicle chargers, battery charging systems, and power inverters. It is also used in industrial applications, such as AC or DC motor controllers, power supplies, and electrical control systems. In addition, the device can be used in a variety of other applications, such as household battery chargers, home security systems, and medical electronics.

In conclusion, the BAS21PGX rectifying diode array is a reliable and cost-effective solution for applications that require reverse polarity protection. Its compact size, wide range of features and capabilities, and broad range of applications make it an ideal choice for engineers and designers.
