Mitigation of Space-Charge-Modulation in 800-V JFET for HV Start-up Circuit Toward High ON-BV Performance

In this work, a high-voltage (HV) junction field effect transistor (JFET) with voltage class extended to 800 V is proposed, which obtains a satisfactory on-state breakdown voltage (ON-BV) performance. For the traditional HV JFET, ON-BV is much lower than OFF-BV, which cannot meet the requirement for the application of high voltage start-up circuit. In pursuit of a high ON-BV and making it close to...
