Absolute Maximum Ratings (Ta = 25°C)
Characteristic Symbol Rating Unit
Maximum (peak) reverse voltage VRM 85 V
Reverse voltage VR 80 V
Maximum (peak) forward current IFM 300 mA
Average forward current IO 100 mA
Surge current (10ms) IFSM 2 A
Power dissipation P 150 mW
Junction temperature Tj 125 °C
Storage temperature range Tstg −55~125 °C
Note: 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).
