(2) Average forward current: IF(AV) = 2 A
(3) Repetitive peak reverse voltage: VRRM = 40 V
(4) Small, thin package suitable for high-density board assembly
Toshiba Nickname: S-FLATTM

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).
Note 1: T= 105 , square wave (α = 180°), VR = 20 V
Note 2: f = 50 Hz, half-sine wave
