Schottky Rectifier Diode
• Reverse voltage: 30 V
• Forward current: 2 A
• Low forward voltage: 0.53 V typ. @ 2 A
• Low leakage current 40 µA typ. @ 30 V
• Low capacitance: 30 pF typ. @ 5 V
• High ESD / transient robustness according to:
ESD (HBM): Class 3 B (> 8000 V)
ESD (MM): Class C ( > 400 V)
ISO7637-2: Pulse 1 ( -100 V, 2 ms)
Pulse 2 (-300 V, 50 µs)
Pulse 3 (-400 V, 100 ns)
• For high efficiency DC/DC conversion,
fast switching, polarity protection, rectification
and clamping applications
• Very small SMD package (2.0 x 1.25 x 0.9 mm³)
with improved operating temperature range
due to extra-low thermal resistance design
(see attached Forward current curves)
• Ideal to replace SMA packages with significant
size advantage
• Pb-free (RoHS compliant) package
• Qualified according AEC Q101
