Transcription

1 Power Schottky rectifier Features High junction temperature capability valanche rated Low leakage current Good trade-off between leakage current and forward voltage drop High frequency operation 1 2 K 2 1 K STPS3H6CFP Description Dual centre tab Schottky rectifier suited for high frequency switch mode power supply. Packaged in, TO-22B, TO-247, I 2 PK, and D 2 PK, this device is intended to be used in notebook and LCD adaptors and desktop SMPS. In these applications the STPS3H6C provides a good margin between the remaining voltages applied on the diode and the voltage capability of the diode.
