Unit: mm
• Repetitive peak reverse voltage: V_RRM = 800 V
• Average forward current: I_{F (AV)} = 0.5 A
• Forward voltage: V_FM = 2.5 V (max)
• Very fast reverse-recovery time: t_rr = 100 ns (max.)
• Suitable for compact assembly due to small surface-mount package

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).
Note3: This rating specifies the non-repetitive peak current in one cycle of a 50 Hz sine wave, condition angle 180°.
Therefore the rating applies only to abnormal operation, which seldom occurs during the lifespan of a device.
