Note2: Using continuously under heavy loads (e.g. the 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).

There is a possibility that SBD will cause thermal runaway when used under high-temperature or high-voltage conditions. Be sure to take forward and reverse loss into consideration during design. 2) The absolute maximum ratings, are rated values that must not be exceeded during operation, even for an instant. The following are the general derating methods that we recommend for when designing a circuit incorporating this device. VRRM: Use this rating with reference to (1) above. VRRM has a temperature coefficient of 0.1%/°C. Take this temperature coefficient into account when designing a device for operation at low temperatures. IF (AV): We recommend that the worst case current be no greater than 80% of the maximum rating of IF (AV) and that Tj be below 100°C. When using this device, take the margin into consideration by using an allowable Tamax-IF (AV) curve. IFSM: This rating specifies the non-repetitive peak current. This applies only to abnormal operation, which seldom occurs during the lifespan of the device. Tj: Derate this rating when using the device in order to ensure high reliability. We recommend that the device be used at a Tj of below 100°C. 3) Thermal resistance between junction and ambient fluctuates depending on the mounting condition of the device. When using the device, design the circuit board and soldering land size to match the appropriate thermal resistance value. 4) Refer to the databook on Rectifiers for further information. 2 2007-11-06 CLS02 PF (AV) – IF (AV) Instantaneous forward current Average forward power dissipation PF (AV) (W) 10.0 iF (A) iF – vF 100 Tj = 125°C 10 75°C 1 25°C 0.1 Pulse test 0.01 0.0 0.2 0.4 0.6 0.8 Instantaneous forward voltage DC 8.0 180° 6.0 α = 60° 4.0 Rectangular waveform 2.0 0° α 360° Conduction angle α 0.0 1.0 vF 120° 0 4 (V) 100 40 0° α 360° IF (AV) Conduction angle α VR = 20 V 20 0 DC 180° Rectangular waveform 60 0 4 8 12 Average forward current (A) IF (AV) Device mounted on a glass-epoxy board (board size: 50 mm × 50 mm) (board thickness: 1.6 t) (soldering land) Cathode 5.7 mm × 6.2 mm Anode 4.5 mm × 3.4 mm 120 100 Ta max (°C) Maximum allowable temperature 120 80 Rectangular waveform DC 60 α = 180° 40 0° α 360° IF (AV) Conduction angle α VR = 20 V 20 0 16 0 4 (A) 8 12 Average forward current IF (AV) 16 (A) rth (j-a) – t 1000 Transient thermal impedance rth (j-a) (°C/W) Maximum allowable lead temperature Tℓ max (°C) 140 120° IF (AV) 16 Ta max – IF (AV) Tℓ max – IF (AV) α = 60° 12 Average forward current 140 80 8 500 300 100 50 30 10 5 3 Device mounted on a glass-epoxy board (board size: 50 mm × 50 mm) (board thickness: 1.6 t) (soldering land) Cathode 5.7 mm × 6.2 mm Anode 4.5 mm × 3.4 mm 1 0.5 0.3 0.1 0.001 0.003 0.01 0.03 0.1 0.3 Time 1 3 t 3 10 30 100 300 1000 (s) 2007-11-06 CLS02 Surge forward current (non-repetitive) (typ.)
