1.6 BVebo: Emitter-Base breakdown voltage (A.01.20)
[Supported Analyzer]
B1500A, 4155B, 4155C, 4156B, 4156C
[Description]
Measures the emitter current vs emitter voltage characteristics, and extracts the Emitter-Base junction
breakdown voltage (BVebo). Collector and Substrate are opened.
[Device Under Test]
Bipolar transistor
[Device Parameters]
Polarity: NPN (SMUs force the specified value) or PNP (SMUs force the negative specified value).
