FR203TA

FR203TA is a CR-type single-phase bridge rectifier. It has a maximum average forward rectified current of 3A, a non-repetitive peak forward surge current of 16A, a reverse voltage of 200V and an average forward voltage drop of less than 1V. With its small size, it is an ideal choice for rectifying low frequency AC power.

The application field of FR203TA includes AC-DC power supplies, welding power supplies, medical power supplies, battery chargers and DC motor drives. This rectifier can be used to convert low frequency AC current from the power source into continuous DC current. The output DC current is then used to power different applications such as AC-DC power supplies, welders, and medical equipment such as cardiographs and defibrillators.

The working principle of FR203TA is based on the use of four diodes connected in a full-wave bridge configuration. When AC current is applied to the diode bridge, two diodes will be forward biased and two will be reverse biased. The two forward biased diodes will conduct current, while the two reverse biased diodes will not conduct current. This creates a full-wave rectified output. The output voltage will be twice the peak voltage of the input AC current.

In summary, FR203TA is a single-phase bridge rectifier with a maximum average forward rectified current of 3A, a non-repetitive peak forward surge current of 16A, a reverse voltage of 200V and an average forward voltage drop of less than 1V. It is suitable for applications such as AC-DC power supplies, welding power supplies, medical power supplies, battery chargers and DC motor drives.
