In particular, low noise JFETs exhibit low input gate currents that are desirable when working with high impedance devices at the input or with high value feedback resistors (e.g., ≥1MΩ). Operational ...

Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...

Infineon Technologies is to develop a two-terminal semiconductor device that acts as a circuit breaker for hundreds of volts and amps: doubling the performance of its mains-voltage super-junction ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

The Junction Field Effect Transistors (JFET) has a channel consisting of N-type semiconductor or P-type semiconductor material and the gate is made of the opposite semiconductor type. The junction FET ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

As the universe of applications for power devices grows, designers are finding that no single semiconductor can cover the full range of voltage and current requirements. Instead, combination circuits ...
