collecting zone
collecting zone
- 无论NPN型还是PNP型管，三极管内部均有三个区、即发射区、基区、集电区，三个区形成两个PN结。
Regardless of type NPN or PNP-type tubes, the internal transistor has three areas, namely, the launch area , base, collector area, the three areas form two PN junction. - 扩展电阻的测试结果显示出注入的P离子基本上集中在集电区的位置，对发射区和基区未造成显著影响。
Measurement results of impurity concentration show that implanted P element distributes mainly in collector region and has no obvious influence to the impurity distribution in emitter and base. - 并得到了一个保证集电结发生雪崩击穿之前不发生基区穿通的判据。
Particularly, a criterion for base punch-through not to occur before collector junction avalanche breakdown is obtained.
