High-voltage semiconductor-based capacitors

24 November 2021 Passive Components

MACOM Technology Solutions’ KV CAPS are high density, high working voltage silicon capacitors which employ a novel topology that essentially folds the parallel plates of the capacitors into three-dimensional structures, producing greater capacitance per unit area of die footprint than that of a simple parallel plate capacitor. This technology employs high-reliability materials and wafer processing which have been staples of the semiconductor industry for decades.

According to MACOM, KV CAPS have the highest available working voltage ratings for silicon-based capacitors. These products are offered with 200 V or 500 V working voltage ratings and are ideal for use in demanding chip-and-wire circuits for DC blocking, AC bypass and resonant-circuit applications.

The capacitors feature very small change in capacitance versus temperature, typically varying by less than ±0,5% over the temperature range of -55°C to +300°C. Their capacitance is not affected by bias voltage and their long-term capacitance stability is excellent, as is their reliability.

KV CAPS have very low equivalent series resistance and equivalent series inductance. They are fully compliant with RoHS requirements, meet numerous military standards, and are suited for use in demanding, high-reliability market applications as found in aerospace and defence, industrial, test and measurement, medical, automotive and more.
