To identify a particular SMD device, first identify the package style and note the ID code Some of the transistors are types with integrated resistors; in the.. - These markings include: Manufacturer Logo and\or SMT code. For example, if you know its a transistor, you could verify the type of transistor . - Identifying the manufacturers ' type number of an SMD device from the package code In this case, p6A is a jfet, and 6Ap a bipolar transistor..
S.D S.d is the essence when soldering surface-mount components especially semiconductors. All SM components will withstand immersion in solder for 10 seconds but this is because the solder is kept at the lowest temperature possible..The first high-frequency transistor was the surface-barrier germanium transistor developed by Philco in 1953, capable of operating up to 60 MHz. These were made by etching depressions into an N-type germanium base from both sides with jets of Indium III sulfate until it was a few ten-thousandths of an inch thick..Back to Sam's Gadget FAQ Table of Contents.
