Hacks of Electronics
A TVS (Transient Voltage Suppression) diode is a specialized semiconductor device used to protect electronic circuits from high-voltage transients such as electrostatic discharge (ESD), lightning surges, and switching spikes. It responds extremely fast and clamps overvoltage to a safe level before they damage sensitive components. Modern electronic systems are highly sensitive to voltage spikes caused […]
A surge protector is an electronic protection device designed to safeguard electrical and electronic equipment from voltage surges (transient overvoltage). A voltage surge is a sudden and short-duration spike in voltage that exceeds the normal operating voltage of a system. These surges may last from a few nanoseconds to milliseconds but can reach several kilovolts […]
Understanding the difference between Surge Protection and Over Voltage Protection is essential for designing robust electronic systems, selecting the right protective components, and complying with safety and EMC standards. Modern electronic and electrical systems are increasingly sensitive to abnormal voltage conditions. With the widespread use of microcontrollers, SMPS power supplies, communication modules, and semiconductor devices, […]
Walk into almost any attic, basement, or storage closet and you will find a small museum of forgotten technology. There is usually a clock radio that once woke someone up for work every morning, a cassette player that fueled road trips, or a VCR that still holds a half-finished movie inside. Many of these devices […]
Printed Circuit Board (PCB) assembly is the heart of modern electronic product manufacturing. Two primary methodologies dominate PCB assembly: Surface Mount Technology (SMT) and Through-Hole Technology (THT). Each technology has unique characteristics, advantages, limitations, and ideal use cases. This article presents a detailed, side-by-side examination of SMT and THT, covering fundamentals, process steps, component types, […]
While a BCD adder performs decimal addition using binary hardware with correction logic, a BCD subtractor performs the subtraction of one BCD number from another and produces a valid BCD result. This requires additional logic because simple binary subtraction does not automatically produce valid BCD outputs. Digital systems frequently need to perform arithmetic operations such […]
