Vishay Intertechnology introduced two new surface-mount Automotive Grade silicon PIN photodiodes in the compact 0805 case size with a low 0.7 mm profile — 0.15 mm lower than previous-generation devices. Offered in black packages, the opaque sidewalls of the Vishay Semiconductors VEMD4010X01 and VEMD4110X01 eliminate unwanted side illumination to increase their signal to noise ratio. The AEC-Q101 qualified photodiodes are optimized for …
The Over-current limit load switch project presented here provides full protection to devices and loads from access load conditions. The default current limit is set to 1 Amp, however, this load limit is adjustable from 0.4A to 2A with the help of R4 ISET resistor. When an overload condition occurs circuit responds to that overload condition that lasts longer than …
