Diodes are electrical components that allow current in one direction while blocking current in the opposite direction. The BAS70 is one traditional example of a single rectifier diode. These diodes are specifically designed to stand up to high-frequency, repeated shock, and vibration within high temperature environments. As such, they are manufactured by companies like Diodes Incorporated for use in automotive, commercial, and industrial applications to contain high current spikes, regulate over-voltage, act as signal rectifiers, or as television flyback protection.

Appearance of the BAS70 Diode

The BAS70 is an SOD-123 package flip chip type diode. It has a very small, square shape and includes a glass-passivated anode lead, an N-type cathode, and an integral strain relief. All the possible conduction paths for the device are built-in, along with a low forward voltage to achieve the best circuit protection. This diode also offers a highly reliable mounting surface and is suitable for use in high temperature, high frequency applications.

Characteristics of the BAS70 Diode

The BAS70 Diode has a maximum reverse voltage rating of 70V and can hold up to a maximum continuous current rating of 350 mA. It also has a very low forward voltage of 0.32 V to achieve the best circuit protection and is can handle up to a maximum power dissipation of 1 W. This diode comes with a thermal resistance of 400 °C/W, a junction-to-ambient thermal resistance of 300 °C/W, an operating temperature range of –55 °C to +125 °C, and a storage temperature range of -55 °C to +200 °C. These features make the BAS70 Diode suitable for use in many high-frequency and high temperature applications.

Working Principle of the BAS70 Diode

The working principle of the BAS70 Diode is simple. A diode is essentially a one-way gate of electricity: it allows an electric current to flow through it in one direction, but blocks it from flowing in the opposite direction. This means that when the voltage across the cathode and the anode is in the forward direction, the diode will allow current to flow and when it is in the reverse direction, the diode will block current, preventing it from flowing. The BAS70 Diode, in particular, uses this one-way flow of electric current to help regulate voltage and protect circuits from high current spikes and over-voltage. This is why it is often used in automotive, commercial, and industrial applications.

Applications of the BAS70 Diode

The BAS70 Diode is commonly used in many applications where a high frequency, low-profile, and reliable rectifier is required. These diodes are perfect for use in automotive applications like ignition systems, headlights, and turn-signals; in commercial applications like cell phone chargers, switching power supplies, and motor control circuits; and in industrial applications like medical devices, process control equipment, and factory automation. Additionally, these diodes are commonly used in TVs, monitors, and other display devices to protect the circuitry from high current spikes and to provide the necessary rectification for the backlighting.
