Thyristors application specific devices

A.S.D. (Application Specific Discretes) technology is a vertical integrated power technology using a full planar process. By applying the masking process on both sides of the chip, higher current density is achievable than is possible with epitaxial base or horizontal structures.

It provides improved reliability through the outstanding ruggedness of the device, as well as enhanced performance resulting from design dedicated to the application. For example, EMI filtering capability is greater than with discrete circuitry.

Their integration allows component count reduction by a ratio of 2 to 6, which leads to smaller PCBs and lower costs, while maintaining the high-voltage and high-current-density capability normally associated with discrete components. The range includes products for street lighting HID ignition, as well as gas and oil boiler ignitors and inductive ballast fluorescent lamp starters.
