Potential source of low cost ZTX avalanche transistors: Stability datasueet all types has been improved by power burn-in.
Instrum Vol 64, No. Makers of the Microchip: Kuthi, USA Sept For a pockels driver requiring something in the order of a 3. Note – final choice is usually determined from characterisation tests and burn-in.
Teruya Avalanche transistor selection for long-term stability in 2n300 camera sweep and pulser applications, 5 September Using a Tektronix curve tracer on the V range, I selected all transistors that had the highest breakdown voltage. High current handling 5. Older diffused-junction types sometimes do.
2N Datasheet PDF – Boca Semiconductor
A base layer in the 2n320 of the epitaxial layer is of thickness about one-fourth the thickness of the epitaxial layer. Asian sources of cheap Zetex avalanche transistors pedigree unknown. Pinout best suited for low C, L Vcbo as high as possible fewer devices: R – T R ansistor selection criteria for avalanche. 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.
Teruya Avalanche transistor selection for long-term stability in streak camera sweep and pulser applications, 5 September http: I determined the breakdown voltage with the aid of a Tektronix curve tracer, see bottom of this page for further details.
Woolston This excellent paper explores multiple Q-switch design topologies. Transistor selection – best transistor dataasheet for avalanche.
Note – I have not bought from this source. An emitter layer in the base layer is of thickness about six-tenths the thickness of the base layer. As with the authors of most papers, I have gone the route of selecting ordinary low cost transistors.
I intend 2n30200 run more tests and measurements based on this paper. Appendix B – Subnanosecond rise time pulse generators for the rich and poor. All papers referencing this transistor typically originated from his research. Vcbo close to Vceo Of the three transistors selected in paper A7, only the 2N is readily available in An automatic avalanche transistor burn-in tester allows power burn-in of up to transistors at a time. I assume the reason for suggesting older devices are better, datasheer which I read: Larkin, Highland Technology Inc.
Data are collected 2n302 each run and stored. Also contains many other topics of interest http: However transistors were avalanched long before this, as earlier papers below reveal.
I found paper [A22] only after writing all of this up.
Data runs were typically 3 to 4 months long, with readings taken weekly. A Documentary History of Fairchild Semiconductor. Williams, 9 October Fast and RF transistors tend to work 2n30220 well. Vcbo being close to Vceo’ http: TO is aka SOT54; manufacturer known only where stated abbreviations: Motorola, Zetex and National transistors were operated at microamperes pA [sic], and the Raytheon units were operated at 20 pA. Selection of avalanche transistors for the LHC Project.
The electric field causes migration of material in the high field region at the surface near the collector-base junction, creating the voltage instability. The Zetexes are made in Russia, presumably on an old fab line. Frequency at least MHz 7.
