CMS03 TOSHIBA Schottky Barrier Rectifier Schottky Barrier Type CMS03 Switching Mode Power Supply Applications Unit: mm Portable Equipment Battery Applications • Repetitive peak reverse voltage : VRRM = 30 V • Average forward current : IF (AV) = 3 A • Peak forward voltage : VFM = 0.45 V (max) • Suitable for compact assembly due to small surface-mount package “M−FLATTM” (Toshiba package name) Absolute Maximum Ratings (Ta = 25°C) Characteristics Symbol Rating Unit Repetitive peak reverse voltage VRRM 30 V Average forward current IF (AV) 3 (Note 1) A Non-repetitive peak forward surge current IFSM 40 (50 Hz) A Junction temperature T j −40 to 150 °C Storage temperature Tstg −40 to 150 °C Note 1: Tℓ = 117.6°C Rectangular waveform (α = 180°), VR = 15 V Ta = 28.4°C Device mounted on a ceramic board JEDEC ― Board size : 50 mm × 50 mm Soldering land size : 2 mm × 2 mm JEITA ― Board thickness : 0.64 mm TOSHIBA 3-4E1A Note 2: Using continuously under heavy loads (e.g. the application of Weight: 0.023 g (typ.) high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
