Multiple electronic components: combination capacitor and Zener diode
View Patent ↗A Zener diode—capacitor combination wherein a Zener diode is mounted in the capacitor body and connected in parallel with the capacitor after the capacitor has been voltage tested. A welded strap or jumper wire completing the diode circuit or a connection of separate terminations during soldering may be used to complete the circuit.
1. An electronic device comprising:
an encasement comprising no more than one capacitor and no more than one zener diode:
a first leadframe extending from said encasement with a first terminal of said capacitor and a first terminal of said Zener diode in common electrical connection with said first leadframe wherein said first terminal of said capacitor and said first terminal of said Zener diode are of opposing polarity;
a segmented second leadframe extending from said encasement wherein said segmented second lead frame comprises a first segment and a second segment wherein a second terminal of said capacitor is in electrical connection with said first segment and a second terminal of said Zener diode is in electrical connection with said second segment.
2. An electronic device according to claim 1 wherein the capacitor has an anode material selected from metals or compounds capable of forming a dielectric oxide by electrochemical anodization.
3. A capacitor according to claim 2 wherein the anode material is selected from the group consisting of Ta, Nb, Ti, Zr, Hf, their alloys and oxides.
4. An electronic device according to claim 1 wherein the encasement is a non-conductive resin.
5. An electronic circuit containing the electronic device of claim 1 .
6. Multiple electronic components in a single sealed package wherein each of said multiple electronic components is electrically connected to one common terminal extending from said package and each of said multiple electronic components is electrically connected to separate terminals extending from said package wherein no more than one component of said components is a capacitor and no more than one component of said components is a Zener diode wherein said capacitor has opposite polarity from said Zener diode.
7. Multiple electronic components according to claim 6 wherein one component is an electrolytic capacitor.
