1SS393,LF Description

Short technical summary and product information.

The Toshiba 1SS393,LF is a Schottky barrier diode array featuring two diodes in a common cathode configuration. Designed for high-speed switching applications, it offers low forward voltage and low reverse leakage current. The device is housed in a compact SC-70 surface-mount package, suitable for space-constrained designs.

 

Key electrical characteristics include a maximum reverse voltage of 40V (45V peak), average forward current of 100mA per diode, and a forward voltage of typically 0.54V at 100mA. Reverse leakage current is limited to 5µA at 40V. The diode array also features a total capacitance of 18pF typical, making it suitable for high-frequency applications.

 

The common cathode configuration simplifies PCB layout for circuits requiring two diodes with a shared cathode, such as in rectification, clamping, or protection circuits. The device operates over a temperature range of -40°C to 100°C and can withstand junction temperatures up to 125°C. Power dissipation is rated at 100mW.

 

The SC-70 (SOT-323) package is widely used in portable electronics and other miniaturized designs. The part is RoHS3 compliant and has an MSL of 1 (unlimited), though these compliance statuses are unverified.
