1SS400SMT2R Description

Short technical summary and product information.

The 1SS400SMT2R is a high-speed switching diode from ROHM Semiconductor, designed for applications requiring fast switching and low capacitance. It features an epitaxial planar structure, ensuring reliable performance. The diode is rated for a reverse voltage of 80V DC and a repetitive peak reverse voltage of 90V. The average rectified forward current is 100mA, with a maximum forward current of 225mA and a peak surge current of 500mA (t=1s).

 

Key electrical characteristics include a maximum forward voltage of 1.2V at 100mA, a reverse leakage current of 100nA at 80V, and a capacitance between terminals of 3pF at 0.5V and 1MHz. The reverse recovery time is 4ns under test conditions (VR=6V, IF=10mA, RL=100Ω). The operating junction temperature can reach up to 150°C.

 

The diode is offered in a surface-mount SOD-523 (SC-79) package, also known as EMD2. It is supplied in tape and reel packaging with 8000 pieces per reel, suitable for automated assembly. The mounting type is surface mount. Compliance data indicates RoHS3 compliant and REACH unaffected, though these are unverified.
