Teruya Avalanche transistor selection for long-term stability in streak camera sweep and pulser applications, 5 September http: Vcbo as high as possible fewer devices: Teruya Avalanche transistor selection for long-term stability in streak camera sweep and 2j3020 applications, 5 September Data runs were typically 3 to 4 months long, with readings taken weekly. Also contains many other topics of interest http: Woolston This excellent paper explores multiple Q-switch design topologies.
The electric field causes migration of material in the high field region at the surface near the collector-base junction, creating the voltage instability. Using a Tektronix curve tracer on the V range, I selected all transistors that had the highest breakdown voltage. Potential source of low cost ZTX avalanche transistors: A Documentary History of Fairchild Semiconductor. Pinout best suited for low C, L High current handling 5.
I intend to run more tests and measurements based on this paper.
For a pockels driver requiring something in the order of a 3. Data are collected from each run and stored. Makers of the Microchip: I determined the breakdown voltage with the aid of a Tektronix curve tracer, see bottom of this page for further details.
As with the authors of most papers, I have gone the route of selecting ordinary low cost transistors. R – T R ansistor selection criteria for avalanche. An emitter layer in the base layer is of thickness about six-tenths the thickness of the base layer.
TO is aka SOT54; manufacturer known only where stated abbreviations: Williams, 9 October Vcbo being close to Vceo’ http: Note – final choice is usually determined from characterisation tests and burn-in. A base layer in the surface of the epitaxial layer is of thickness about one-fourth the thickness of the epitaxial layer. Stability on all types has been improved by power burn-in.
Selection of avalanche transistors for the LHC Project. I assume the reason for suggesting older devices are better, into which I read: Datawheet and RF transistors tend to work as well.

Unfortunately, like all earlier transistors, the edge of the collector-base junction was exposed, making it sensitive to leakage through surface contaminants, thus requiring hermetic seals or passivation to prevent degradation of the transistor’s characteristics over time.
Older diffused-junction types sometimes do. Larkin, Highland Technology Inc.
Note – I have not bought from this source. Motorola, Zetex and National transistors dataheet operated at microamperes pA [sic], and the Raytheon units were operated at 20 pA. I found paper [A22] only after writing all of this up.
Vcbo close to Vceo Transistor selection – best transistor types for avalanche.
Appendix B – Subnanosecond rise time pulse generators for the rich and poor. An automatic avalanche transistor burn-in tester allows power burn-in of up to transistors at a time. The Zetexes are made in Russia, presumably on an old fab line.
Instrum Vol 64, No.
All papers referencing this transistor typically originated from his research. Kuthi, USA Sept Frequency at least MHz 7. Asian sources of cheap Zetex avalanche transistors pedigree unknown. However transistors were avalanched long before this, as earlier papers below reveal. Of the three transistors selected in paper A7, only the 2N is readily available in
