Web1N4148 are much smaller devices encapsulated in a glass body. (1N914 is an identical device to the 1N4148) They will do exactly the same job in switch and lamp matrixes for pinball BUT the 4004/7 is a much tougher device and will withstand the shaking and bashing a lot better than the more fragile glass bodied diode.

WebMar 24, 2024 · Other materials, such as ceramics, can have a broad range of CTE values. As an example, aluminum nitride is very useful for its high thermal conductivity, but the CTE value is quite low (from 4.3 to 5.8 ppm/°C). CTE is important both at high temperature and when the board temperature is repeatedly cycled between high and low values. WebJul 28, 2014 · The glass package also allows a very high operating temperature. Early devices such as the 1N34A (germanium) and the 1N914 as well as the 1N7xx Zener series became very popular and inexpensive. Plastic-packaged devices were developed to …
WebZERØ™（Zero CTE Glass） Low-thermal-expansion glass technology has a broad range of uses, from the ordinary to the state-of-the-art. You might find it a little strange to hear that glass expands. However, regular glass does indeed expand a micron or two. For example, if you pour boiling water into a normal glass cup, it will crack. WebMar 2, 2006 · 2. The body diode of a MOSFET or even a FREDFET is not optimized for reverse recovery like a discrete diode is. Like any conventional silicon diode, body diode reverse recovery charge and time depend on temperature, di/dt, and current. The forward voltage of the body diode, VSD, decreases with temperature by about 2.5 mV/°C. …
WebApr 9, 2015 · The big advantage of a SiC MOSFET is the very good parasitic body diode. Since it is fully qualified one can use the body diode of Rohm’s SiC MOSFET for free-wheeling, which can save significant cost.
