BAT54TA

A BAT54TA is a silicon, surface-mount, small-signal Schottky diode. It is a single rectifier with a low forward voltage and low leakage current. A BAT54TA has a fast switching speed and low capacitance, making it ideal for high-frequency applications. It is commonly used in switch-mode power supplies, lightning protection circuits, AC/DC converters, and voltage clamping circuits.

The difference between a Schottky diode and a normal diode is that a Schottky diode has a lower forward drop, lower leakage current and faster switching speeds. This makes them suitable for use in high-speed, low-power applications. Because of these advantages, Schottky diodes are commonly used for protection circuits and high-frequency switching applications.

The working principle of a BAT54TA diode is that when a voltage is applied across its terminals, the diode will start to conduct and will allow current to flow through it. When the applied voltage is removed, the diode will turn off and will no longer conduct current. The voltage required to turn the diode on is known as the forward voltage, or “on-voltage”. The reverse voltage is the voltage at which the diode will no longer conduct current.

The BAT54TA has a maximum reverse voltage of 60V, a maximum forward current of 10A and a maximum repetitive peak reverse voltage of 90V. Its junction capacitance is 11pF typical, at 1MHz. It has a maximum power dissipation of 500mW. The machine model number is BAT54TA.

In conclusion, a BAT54TA is a single rectifier Schottky diode with a low forward voltage, low leakage current, fast switching speed and low capacitance. It is suitable for high-frequency applications such as switch-mode power supplies, lightning protection circuits, AC/DC converters, and voltage clamping circuits. It has a maximum forward current of 10A, maximum reverse voltage of 60V and a junction capacitance of 11pF typical, at 1MHz.
