PN Junction Theory
https://www.electronics-lab.com/article/pn-junction-theory/
PN Junction Introduction It is better to briefly revise the basic semiconductor theory before starting the PN junction theory. As we know, the N-type semiconductor has electrons as majority carrier and holes as minority carrier. The impurity in N-type semiconductor is a donor and has a bound positive charge which neutralizes majority electrons as a […]
Nexperia Silicon Germanium (SiGe) rectifiers offer Cutting-edge high efficiency
https://www.electronics-lab.com/nexperia-silicon-germanium-sige-rectifiers-offer-cutting-edge-high-efficiency/
Nexperia’s SiGe rectifiers combine the high efficiency of Schottky rectifiers with the thermal stability of fast recovery diodes. Targeting automotive, server markets, and communications infrastructure, the AEC-Q101 compliant rectifiers are of particular benefit in high-temperature applications. These extremely low leakage devices allow an extended safe-operating area with no thermal runaway up to 175 °C. And, […]

MCC’s SiC diodes are well-suited for inverters for solar and motion control, UPS, Telekom base stations, PFC, and lighting Micro Commercial Components’ high-performance SiC Schottky diodes provide a high-efficiency, high-temperature performance of up to +175°C. These diodes, together with the 650 V super-junction MOSFETs, create a complete cost-efficient discrete solution. These SiC diodes are available […]
Adjustable Constant Current LASER Diode/LED driver
https://www.electronics-lab.com/adjustable-constant-current-laser-diode-led-driver/
I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable. Laser diodes are harmful and should have some sort of constant […]

Littelfuse, Inc. today introduced two second-generation series of 650V, AEC-Q101-qualified silicon carbide (SiC) Schottky Diodes. The LSIC2SD065CxxA and LSIC2SD065AxxA Series SiC Schottky Diodes are available with a choice of current ratings (6A, 8A, 10A, 16A or 20A). They offer power electronics system designers a variety of performance advantages, including negligible reverse recovery current, high surge […]
Unlimited Source of Energy- As good as it Sounds
https://www.electronics-lab.com/unlimited-source-energy-good-sounds/
In recent decades, humans realized that fossil fuels are a finite source of energy that not only pollutes the environment but is also difficult to extract (it can even be dangerous). Because of this, there has been a huge increase in the development of new ways to extract energy from other sources such as solar, […]
Characteristics and applications of fast recovery epitaxial diodes
https://www.electronics-lab.com/characteristics-applications-fast-recovery-epitaxial-diodes/
Read about epitaxial ultrafast diodes in thia app note from IXYS. (PDF) During the last 10 years, power supply topology has undergone a basic change. Power supplies of all kinds are now constructed so that heavy and bulky 50/60 Hz mains transformers are no longer necessary. These transformers represented the major part of volume and […]
SUNY Polytechnic Creates 3-in-1 Device That Can Be A Diode, A MOSFET And A BJT
https://www.electronics-lab.com/suny-polytechnic-creates-3-1-device-can-diode-mosfet-bjt/
In a recently published study, a team of researchers at SUNY Polytechnic Institute in Albany, New York, has suggested that combining multiple functions in a single semiconductor device can significantly improve device’s functionality and efficiency. Nowadays, the semiconductor industry is striving to scale down the device dimensions in order to fit more transistors onto a computer […]
Analog front-end IC linearizes sensors
https://www.electronics-lab.com/analog-front-end-ic-linearizes-sensors/
Susan Nordyk @ edn.com discuss about LTC2986 which is able to digitize and linearize a combination of temperature sensors in Celsius or Fahrenheit degrees. A 10-channel temperature-measurement IC, the LTC2986 from Linear Technology directly digitizes any combination of thermocouples, RTDs, thermistors, and external diodes with 0.1°C accuracy and 0.001°C resolution. The analog front-end device combines […]
