  1. 상식자료
    1. 04/08/00 <a href="diode-01.pdf">파워다이오드 기본 특성 및 선정(diode-01.pdf)</a> - 트랜지스터 기술 월간지에서, 26p
    2. 종류
      1. 정류용
        1. rectifier: 역방향 회복시간이 1000ns~10us. AC 정류기용.
        2. fast recovery diode(FRD): 100~1000ns(일반에 비해 역회복시간이 5~10배 짧다), 댐퍼 및 모니터용
        3. ultra fast recovery: 100nsec 이하. SMPS 스위칭용
      2. schottky barrier diode(SBD) 쇼트키 배리어 다이오드
        1. 역회복시간이 존재하지 않으나, 내부 C 때문에 존재하지만 가장 빠른 역회복 시간을 갖는다.
        2. ultra fast recovery에서, 순방향 전압강하가 낮다. 즉, low loss ultra fast recovery이다.
          1. 소신호 실리콘은 UHF 검파, 믹서용, 고속 스위칭
          2. GaAs: 소신호에서, 더 높은 주파수까지 검파, 믹서용, 고속 스위칭
          3. 정류용: 순방향 전압강하가 작다. 역방향내압 높이기 어려워 30~40V까지이므로 저전압,대전류 전원정류용. 역회복시간이 작아 고주파 정류하는 스위칭 전원용
      3. Zenor 다이오드
      4. Varicap 다이오드; 예) BB202
      5. PIN 다이오드
      6. ESD 다이오드
