TOSHIBA Fast Recovery Diode Silicon Diffused Type CRF02 Power Supply Applications Strobo Flasher Applications

• Repetitive peak reverse voltage: V RRM = 800 V
• Average forward current: IF (AV) = 0.5 A
• Low forward voltage: VFM = 3.0 V (max.)
• Very fast reverse-recovery time: trr = 100 ns (max.)
• Suitable for compact assembly due to its small surface-mount package, the “S−FLATTM” (Toshiba package name) Absolute Maximum Ratings (Ta = 25°C) Characteristics 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) A Junction temperature Tj −40~150 °C Storage temperature range Tstg −40~150 °C Note 1: Ta = 84°C: Device mounted on a ceramic board Board size: 50 mm × 50 mm, Soldering Land size: 2 mm × 2 mm Board thickness: 0.64 t 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).

The followings are the general derating method that we recommend for designing a circuit using this device. VRRM: We recommend that the worst-case voltage, including surge voltage, be no greater than 80% of the absolute maximum rating of VRRM for a DC circuit; and no greater than 50% of that of VRRM for an AC circuit. VRRM has a temperature coefficient (0.1%/ ℃). Be sure to take this temperature coefficient into account when designing a device at low temperature. IF(AV): We recommend that the worst case current be no gr eater than 80% of the absolute maximum rating of IF(AV). Carry out sufficient heat design. If it is not possible to design a circuit with excellent heat radiation, set a margin by using an allowable Tamax-IF (AV) curve. This rating specifies the non-repetit ive peak current in one cycle of a 50-Hz sine wave, condition angle 180 °. Therefore this applies only to abnormal operation, which seldom occurs during the lifespan of the device. For this device, we recommend a Tj of below 120℃ under the worst load and heat radiation conditions. Thermal resistance between junction and ambient fluctuates depending on the mounting condition of the device. When using the device, be sure to design the circuit board and soldering land size to match the appropriate thermal resistance value.
