Description

트랜지스터 보호회로
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 따른 보호회로를 합체한 회로망을 포함하는 텔레비젼 수상기의 일부분을 도시한 개요도.
제2도 내지 제5도는 본 발명에 따른 보호회로와 보호될 회로의 실시예를 도시한 회로도.
제6도는 제2도 내지 제5도에 도시된 회로들의 작동을 이해하는데 도움이 되는 도면.

Claims (1)

  1. 본문에서 설명되고 도면에서 예시된 바와 같이, 전이들이 나타날 수 있는 회로점에 접속된 반도체 접합을 포함하며 전이가 주어진 레벨을 초과할때 손상받을 수 있는 반도체 장치를 스튜리어스 고전압 전이에 의한 전기적 과부하 손상으로부터 보호하기 위한 장치에 있어서, 상기 보호장치가 작동전위에 접속된 콜렉터전극, 베이스전극 및 상기 회로점에 접속된 에미터 전극을 갖는 보호트랜지스터와 상기 베이스 전극의 바이어스가 상기 반도체 장치의 바이어스 상이 회로점의 바이어스에 무관하게 결정되는 방법으로 기준 바이어스 전압을 상기 베이스 전극에 인가하기 위한 장치를 포함하며, 상기 전이가 없을때 상기 보호트랜지스터를 정상적으로 비도전 상태로 유지하기 위하여 상기 기준 바이어스 전압이 상기 보호 트랜지스터를 콜렉터-베이스 접합부를 역방향으로 바이어스 하며 상기 보호 트랜지스터의 베이스-에미터 접합부를 역방향으로 바이어스시키고, 상기 기준 바이어스 전압의 레벨이 전이 전류들을 상기 반도체 장치로부터 멀리 전환시키기 위하여 상기 보호트랜지스터의 에미터-콜렉터 통로가 도전되도록 상기 보호트랜지스터의 베이스-에미터 접합부가 주어진 레벨밑의 임계레벨을 초과하는 저이에 응답하여 순방향으로 바이어스되도록 하는 레벨인 것을 특징으로 하는 트랜지스터 보호회로.
