Switching Mode Power Supply Applications
• Repetitive peak reverse voltage: V_RRM = 400 V
• Average forward current: I_{F (AV)} = 2.0 A
• Low forward voltage: V_FM=1.8 V(Max.)
• Very Fast Reverse-Recovery Time: trr =35ns(Max.)
• Suitable for compact assembly due to small surface-mount package

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).
