BAS70-07

® BAS70-07 SMALL SIGNAL SCHOTTKY DIODE FEATURES AND BENEFITS VERY SMALL CONDUCTION LOSSES NEGLIGIBLE SWITCHING LOSSES LOW FORWARD VOLTAGE DROP LOW THERMAL RESISTANCE EXTREMELY FAST SWITCHING SURFACE MOUNTED DEVICE DESCRIPTION Low turn-on and high breakdown voltage diodes intended for ultrafast switching and UHF detectors in hybrid micro circuits. Packaged in SOT-143, this device is intended for surface mounting. Its dual independent diodes configuration makes it very interesting for applications where high integration is searched.
