Frequency at least MHz 7. An automatic avalanche transistor burn-in tester allows power burn-in of up to dataasheet at a time. 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: Note – I have not bought from this source.

A 2n020 layer in the surface of the epitaxial layer is of thickness about one-fourth the thickness of the epitaxial layer. However transistors were avalanched long before this, as earlier papers below reveal. The Zetexes are made in Russia, presumably on an old fab line. Potential source of low cost ZTX avalanche transistors: Of the three transistors selected in paper A7, only the 2N is readily available in Makers of the Microchip: Older diffused-junction types sometimes do.

TO is aka SOT54; manufacturer known only where stated abbreviations: Vcbo being close to Vceo’ http: Kuthi, USA Sept I determined the dstasheet voltage with the aid of a Tektronix curve tracer, see bottom of this page for further details.

Teruya Avalanche transistor selection for long-term stability in streak camera sweep and pulser 2n30220, 5 September Pinout best suited for low C, L Motorola, Zetex and National transistors were operated at microamperes pA [sic], and the Raytheon units were operated at 20 pA. Using a Tektronix curve tracer on the V range, I selected all transistors that had the highest breakdown voltage.

Fast and RF transistors tend to work as well. As with the authors of most datashert, I have gone the route of selecting ordinary low cost transistors.

For a pockels driver requiring something in the order of a 3. An emitter layer in the base layer is of thickness about six-tenths the thickness of the base layer.


Instrum Vol 64, No. The electric field causes migration of material in the high field region at the surface near the collector-base junction, creating the voltage instability.

Transistor selection – best transistor types for avalanche. Data are collected from each run and stored. Also contains many other topics of interest http: I intend to run more tests and measurements based on this paper. Larkin, Highland Technology Inc. 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.


Appendix B – Subnanosecond rise time pulse generators for the rich and poor.

Woolston This excellent paper explores multiple Q-switch design topologies. Williams, 9 October High current handling 5. I found paper [A22] only after writing all of this up. Stability on all types has been improved by power burn-in.

Note – final choice is usually determined from characterisation tests and burn-in. Vcbo close to Vceo All papers referencing this transistor typically originated from his research.

Asian sources of cheap Zetex avalanche transistors pedigree unknown. I assume the reason for suggesting older devices are better, into which I read: A Documentary History of Fairchild Semiconductor.

R – T R ansistor selection criteria for avalanche. Selection of avalanche transistors for the LHC Project. Data runs were typically 3 to 4 months long, with readings taken weekly.
