In this study, we present a venting clip for high-power applications that is intended to reduce stray inductance. To reduce the stray inductance of packages in high-power applications, the proposed venting clip features slots are inserted onto a conventional clip. A conventional clip and the proposed venting clip were designed and fabricated to compare the respective stray inductance. The inductance of the proposed venting clip was approximately 15.8% than that of the conventional clip at a frequency of 100 kHz. Through a comparison between the conventional and venting clips, it is confirmed that the proposed venting clip is superior for high-power applications in terms of decreasing inductance. With reduced inductance, the switching-loss for such applications is also expected to decrease. Moreover, the impedance of the venting clip decreased by approximately 15.5% compared with that of the conventional clip at a frequency of 100 kHz. The venting clip, which has reduced resistive component, is also expected to decrease conduction loss in highpower applications.
