How fast is a typical body diode of a modern MOSFET?

I would like to know how fast a typical body diode of a modern MOSFET is in terms of letting a voltage spike through. In the datasheets, only the reverse recovery is stated for blocking again, but ...

Recovery of transistor wired as diode

It's a simple question. What's the turn-off time of this "diode" and does it have a recovery time when turning off? Since the transistor does not get into saturation I think it should be the ...

Does spice model saturation recovery of bipolar transistors?

When a bipolar transistor is driven into saturation, it builds up charge which slows the recovery time when it is switched off. What I would like to know is, how well is this behaviour captured in ...

Repairing an SSD using a soldering iron vs oven reflow?

I'm trying to recover data from a cheap kingspec ssd that stopped working some months ago. It is not recognized by the computer at all. I get some messages saying the computer is trying to connect to ...

Why did they use ultrafast diodes in a 50 or 60 Hz bridge?

This is again from an HP power supply (PSU). The incoming 230 V is rectified into 340 VDC and is fed to a switched-mode supply. The odd thing here is that the manual for that unit, HP6023A, ...

What is a typical reverse recovery time for a Zener diode, or is reverse recovery time not applicable to Zener diodes?

A little background: I am trying to understand how Zener diodes respond to high voltage transients. I stumbled across discussions of reverse recovery time, and I'm curious how it applies specifically ...

EPROM memory - the theoretical possibility of recovering data from memory after erasing the exposure with ultraviolet light?

I have a small question. We have a EPROM memory. Is there a theoretical possibility of recovering data from memory after deleting with ultraviolet light? Is this theoretically possible? Or maybe it ...

Proper way to demonstrate reverse recovery time of a diode using SPICE simulation

After encountering a nice example from an answer of this question, I wanted to simulate the same circuit in LTspice to compare the reverse recovery times of two diodes 1N4148 and 1N4007 by a 5V ...
