The case drawings are shown at the bottom of the page. Cases GEC MAZDA STC AEI HIVAC NEWMARKET TEXAS Transistors. OC139 : If you know of an application for these. Please
23/08/2012· The 2N1532 is also a germanium PNP power transistor, similar to a number of other power transistors of the time. It is packaged in the widely recognizable TO-3
Germanium transistor projects intrigued experimenters from the early days in the 1950s until the early 1970s. In the Seventies, the higher-grade silicon devices began to take over the hobby market. Hobbyists adapted, by attempting germanium-to-silicon conversions. Often, the germanium circuits didn't cooperate. Several difficulties occurred. Fortunately, each one had a solution. While the
The trouble with designing for germanium transistors is you're always coming up against a brick wall legended (in best spray-can graffiti style) "can't do it won't go high enough". The basic problem is germanium transistors were / are crap. Crap max. Voltage limit Vce (too low); crap current handling capacity Ic (too low); crap gain Hfe (too low); crap bandwidth Ft (too low); crap power

P-TYPE HIGH-PURITY GERMANIUM COAXIAL DETECTORS Low Transistor reset preamplifiers for ITECH INSTRUMENTS high countP-type HPGe detectors have proven themselves worldwide over many years of unfailing service because they are manufactured in the past by PGT company. They exhibit excellent resolution and peak symmetry, with a used with a mechanical cooler, such as useful energy
Typically a thin wafer of Germanium was used for the base of the transistor. The emitter and collector were made by diffusing two pellets of Indium (a trivalent material, having three electrons in their valence shell) into either side of a wafer of N type base, as shown in Fig 3.2.1. The fusion process causes the indium to diffuse into the

The large-volume n-type HPGe detector, a special design by PGT, was equipped with a transistor reset preamplifier to avoid saturation resulting from interactions of energetic protons and gamma rays with the germanium crystal (for example, a 1.5-GeV proton deposits about 40 MeV in a 5 cm long Ge crystal). In a typical run, about 950 protons and 12200 gamma-rays per second were detected, while

The use of high purity germanium (HPGE) type detectors have the great advantage that they can be allowed to warm up and not suffer damage. This is unlike the older lithium drifted detectors that were not tolerant of any significant warm up because of the associated migration of the lithium ions, resulting in an improperly functioning detector.

Germanium is the gold standard for the detection of gamma rays. Silicon has a larger band gap thus is not as sensitive. Share. Cite. Improve this answer . Follow answered May 26 '11 at 3:42.

Why choose Liverpool? Itâ s an important question. And there are thousands of answers.
BJT transistor: (a) PNP schematic symbol, (b) layout (c) NPN schematic symbol, (d) layout. The functional difference between a PNP transistor and an NPN transistor is the proper biasing (polarity) of the junctions when operating. Bipolar transistors work as current-controlled current regulators. In other words, transistors restrict the amount of current passed according to a smaller
