ANSI/IEEE Bidirectional breakdown diode form
IEEE-library form of bidirectional breakdown diode: a bidirectional breakdown diode provides a documented voltage-limiting semiconductor path in both polarities.
In plain English
What does ANSI/IEEE Bidirectional breakdown diode form mean?
This reference locates bidirectional breakdown diode in Autodesk's IEEE-oriented semiconductor components family. A bidirectional breakdown diode provides a documented voltage-limiting semiconductor path in both polarities. Its working voltage and surge characteristics determine the protective application. The public library uses HDI1_S00647 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Follow the actual current path and terminal polarity in the surrounding circuit. The symbol identifies an electrical function; voltage, current, energy limits and the device package pinout come from the selected component data rather than from the outline.
What the drawings help you do
Read working-voltage and breakdown specifications separately. Bidirectional protection does not make the component a controllable power switch. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

About this graphic
This illustration was authored independently by Elora Grid to explain the concept. It is not reproduced from a customer drawing, an official standard graphic or a manufacturer CAD file. Its correspondence to an exact IEC or IEEE symbol identifier has not been certified.
SVG and DXF downloads contain this original artwork. DXF uses unscaled drawing units; a GA envelope supplies no product dimensions, clearances or fabrication information. Original artwork is available under CC BY 4.0. Third-party references retain their own terms.
