TOSHIBA Fast Recovery Diode Silicon Diffused Type CMF04 High Speed Rectifier Applications (Fast Recovery) Switching Mode Power Supply Applications DC/DC Converter Applications

  • Repetitive peak reverse voltage: VRRM = 800 V
  • Average forward current: IF (AV) = 0.5 A
  • Forward voltage: VFM = 2.5 V (max)
  • Very fast reverse-recovery time: trr = 100 ns (max.)
  • Suitable for compact assembly due to small surface-mount package “M −FLATTM” (Toshiba package name) Absolute Maximum Ratings (Ta = 25°C) Characteristic Symbol Rating Unit Repetitive peak reverse voltage VRRM 800 V Average forward current IF (AV) 0.5 (Note 1) A Peak one-cycle surge forward current (non-repetitive) IFSM 10 (50 Hz) (Note 3) A Junction temperature Tj −40~150 °C Storage temperature range Tstg −40~150 °C Note 1: T ℓ = 127°C Rectangular waveform (α = 180°) Note 2: Using continuously under heavy loads (e.g. t he application of 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). Note3: This rating specifies the non-repetitive peak current in one cycle of a 50 Hz sine wave, condition angle 180 °. Therefore the rating applies only to abnormal operation, which seldom occurs during the lifespan of a device. Unit: mm JEDEC ⎯ JEITA ⎯ TOSHIBA 3-4E1A Weight: 0.023 g (typ.)
