TOSHIBA Diode Silicon Epitaxial Schottky Barrier Type
1SS404
1SS404
High Speed Switching Applications
• Two-pin small packages are suitable for higher mounting densities
• Low forward voltage : VF (3) = 0.38 V (typ.)
• Low reverse current: IR = 50 μA (max)
• Small total capacitance: CT = 46 pF (typ.)

temperature, etc.) may cause this product to decrease in the
reliability significantly even if the operating conditions (i.e.
Weight: 0.004 g (typ.)
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: Mounted on a glass epoxy board of 20 mm × 20 mm,
pad dimension 4 mm × 4 mm.
