With a 4k1 collector resistor and 16mA drive into the led, the chosen (read ‘cheapest on ebay’) 6N135 is supposed to beat 1.5μs for both turn on and turn off, with typical figures of 90ns and 800ns.

Abstract: This article demonstrates the protection effects using transient voltage suppressor (TVS) diodes based circuits under high-power microwave (HPM) pulses. Two types of TVS diodes were studied, ...

For our 2025 Component Abuse Challenge there have been a set of entries which merely use a component for a purpose it wasn’t quite intended, and another which push misuse of a part into ...

This video breaks down how resistors work and why they’re one of the most essential components in every electronic device.

Abstract: The paper describes the planar Gunn diode, which is a device well suited to provide milli-metric and tera-hertz sources using microwave monolithic integrated circuit technologies. Different ...

Electromagnetic waves with frequencies between microwave and infrared light, also known as terahertz radiation, are leveraged ...
