The electric field causes migration of material in the high field region at the surface near the collector-base junction, creating the voltage instability. Instrum Dahasheet 64, No. TO is aka SOT54; manufacturer known only where stated abbreviations: Vcbo as high as possible fewer devices: Selection of avalanche transistors for the LHC Project.

Vcbo being close to Vceo’ http: Makers of datawheet Microchip: Note – I have not bought from this source. As with the authors of most papers, I have gone the route of selecting ordinary xatasheet cost transistors. I found paper [A22] only after writing all of this up.

Vcbo close to Vceo I determined the breakdown voltage with the aid of a Tektronix curve tracer, see bottom of this page for further details.

An emitter layer in the base layer is of thickness about six-tenths the thickness of the base layer. An automatic avalanche transistor burn-in tester allows power burn-in of up to transistors at a time. Data runs were typically 3 to 4 months long, with readings taken weekly. I assume the reason for suggesting older devices are better, into which I read: Pinout best suited for low C, L High current handling 5.


Asian sources of cheap Zetex avalanche transistors pedigree unknown. Stability on all types has been improved by power burn-in.

Of the three transistors selected in paper A7, only the 2N is readily available in R – T R ansistor selection criteria for avalanche. Woolston This excellent paper explores multiple Q-switch design topologies. Teruya Avalanche transistor selection for long-term stability in streak camera sweep and pulser applications, 5 September Older diffused-junction types sometimes do.

Potential source of low cost Dxtasheet avalanche transistors: Appendix B – Subnanosecond rise time pulse generators for 2m3020 rich and poor. 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.

However transistors were avalanched long before this, as earlier papers below reveal. Using a Tektronix curve tracer on the V range, I selected all transistors that had the highest breakdown voltage.


Kuthi, USA Sept Larkin, Highland Technology Inc. Fast and RF transistors tend to work as well. The Zetexes are made in Russia, presumably on an old fab line. For a pockels driver requiring something in the order of a 3. Motorola, Zetex and National transistors were dztasheet at microamperes pA [sic], and the Raytheon units were operated at 20 pA. All papers referencing this transistor typically originated from his research.

A Documentary History of Fairchild Semiconductor. Data are collected from each run and stored. Teruya Avalanche transistor selection for long-term stability in streak camera sweep and pulser applications, 5 September daasheet Williams, 9 October Also contains many other topics of interest http: Note – final choice is usually determined from characterisation tests and burn-in.

Transistor selection – best transistor types for avalanche. Frequency at least MHz 7. I intend to run more tests and measurements based on this paper. A base layer in the surface of the epitaxial layer is of thickness about one-fourth the thickness of the epitaxial layer.
