BAT85 SCHOTTKY BARRIER DIODE
FEATURES :
• For general purpose applications.
• This diode features low turn-on voltage. This device is
protected by a PN junction guard ring against excessive
voltage, such as electrostatic discharges
• This diode is also available in the MiniMELF case with
type designation BAS85.
• Pb / RoHS Free
