UnitedSiC UF3N170400B7S 1700V-400mW SiC Normally-on JFET exhibits ultra-low on-resistance (RDS(ON)) and gate charge (QG) that allows low conduction and switching loss. The low RDS(ON) value of this JFET at VGS = 0V is ideal for current protection circuits without the need for active control and for cascode operation. The UF3N170400B7S 1700V-400mW SiC Normally-on JFET offers a […]

Basic Types of Transistors
https://www.electronics-lab.com/article-basic-transistor-types/
In this article we will review the basic transistor types and their function. We will cover bipolar transistor, Junction FET, MOSFET and UJT transistor types. Feel free to comment with other transistor types you know. Bipolar Transistor Bipolar transistors are three terminal devices and act like electrically controlled switches of as current/voltage amplifiers. They come […]
JFET Moving Coil (MC) Pre-Preamp Kit
https://www.electronics-lab.com/jfet-moving-coil-mc-pre-preamp-kit/
by Mark Houston @ diyaudioprojects.com: I received the Boozhound Labs JFET Moving Coil (MC) Pre-Preamp Kit a while back and I promptly assembled the small circuit board. I’m a sucker for a simple kit and a hot iron. That is where it all stopped. The circuit board remained complete and laying about for a few years. Recently […]
Simple circuit lets you characterize JFETs
https://www.electronics-lab.com/simple-circuit-lets-you-characterize-jfets/
by John Fattaruso @ edn.com: When working with discrete JFETs, designers may need to accommodate a large variation in device parameters for a given transistor type. A square-law equation is usually used as an approximate model for the drain-current characteristic of the JFET: ID=β(VGS−VP)2, where ID is the drain current, VGS is the gate-to-source voltage, β […]
