Additional Details

The U1JC44(TE12R) has a maximum repetitive peak reverse voltage (VRRM) and a maximum average forward rectified current (IF(AV)). The '(TE12R)' suffix likely specifies the package type and tape and reel configuration. Important parameters to consider are the forward voltage (Vf) at a specific forward current (If), the reverse leakage current (Ir) at a specific reverse voltage (Vr), and the maximum operating junction temperature (Tj). Always consult the official Toshiba datasheet for the U1JC44(TE12R) for detailed specifications, including VRRM, IF(AV), Vf, Ir, Tj, and package dimensions. Proper selection of a Schottky diode is crucial for optimal circuit performance and reliability.
