Anode 2. Cathode Junction temperature Tj −40 to 150 °C Storage temperature range Tstg −40 to 150 °C Note 1: Ta = 30°C Device mounted on a ceramic board Board size : 50 mm × 50 mm Land pattern size : 2 mm × 2 mm Board thickness : 0.64 mm JEDEC JEITA TOSHIBA Weight: 0.023 g (typ.) ― ― 3-4E1S Note 2: 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).
