Description and Applications Mechanical Data
Case: X3-WLB1406-2
The SDM1U40CSP is a 40-volt 1A Schottky Barrier Rectifier that is
Moisture Sensitivity: Level 1 per J-STD-020
optimized for low forward voltage drop and low leakage current.
Polarity: Cathode Dot
Housed in a compact chip scale package (CSP), the SDM1U40CSP
2
Weight: 0.001 grams (Approximate)
occupies only 0.84 mm board-space with low profile. The low thermal
resistance enables designers to meet design challenges of increasing
efficiency whilst at the same time reducing board space. It is ideally
suited for use in portable applications as a:
Blocking Diode
Boost Diode
Switching Diode
Reverse Protection Diode
Pin #1
Cathode
Notch
