The recommended operating voltage range for the BU2520AW is 4.5V to 18V, although it can tolerate up to 20V for short periods.
To ensure proper biasing, connect the base of the transistor to a voltage divider network that sets the base voltage to around 2.5V to 3.5V, depending on the application.
The maximum collector current rating for the BU2520AW is 2A, but it's recommended to keep the current below 1.5A for reliable operation and to prevent overheating.
While the BU2520AW can be used as a switch, it's not ideal for high-frequency applications due to its relatively high transition frequency (ft) of around 30MHz. For high-frequency switching, consider using a transistor with a higher ft rating.
To calculate power dissipation, use the formula Pd = Vce * Ic, where Vce is the collector-emitter voltage and Ic is the collector current. Ensure the calculated power dissipation is within the device's rating of 20W.
