Vishay Semiconductors
Small Signal Schottky Diode
FEATURES
• These diodes feature very low turn-on voltage
and fast switching. These devices are protected
by a PN junction guard ring against excessive
voltage, such as electrostatic discharges
• For general purpose applications
• AEC-Q101 qualified available
DESIGN SUPPORT TOOLS
• Base P/N-E3 - RoHS-compliant, commercial grade
click logo to get started
• Base P/N-HE3 - RoHS-compliant, AEC-Q101 qualified
