Help identifying a Sot 23 SMD component with G1 on it

I am trying to identify a fried component in a fan controller. I believe the fan is a PWM fan, and my guess is that this component might be a transistor as part of the PWM circuit because that function is not working when I take readings with a…

Please help identify this SOT-23-3 device marked T22 or T2.2

This looks like any other SOT-23 device: But the markings are turning up little. Pin 1 (bottom-left) has something connected to pin 3 (top.) Pin 2 is N/C. So this seems like a zener, except there are four of these (two each on two malfunctioning…

SOT-23 footprint (difference between KiCAD footprint and NXP)

I'm using some transistors in SOT-23 packages, designing a board in KiCAD 7. NXP's recommended footprint has pads 0.6 x 0.7 mm. Datasheet Vishay's "recommended minimum" has pads 0.559 x 0.725 mm Datasheet KiCAD's pads are much bigger 0.6 x 1.475 mm…

Identifying a maybe bad SOT23 transistor

To give a bit of background, I'm trying to fix a friend's NeoGeo CD console which doesn't read disc: The disc doesn't spin at all, the laser assembly and lens are moving, the diode turns on. But it seems it didn't detect any disc and so never make…

Is difference in height between TSOT and SOT decreased over the years?

As specifics: SOT height is between 0.90mm to 1.45mm TSOT height is between 0.90mm to 1.00mm I've measured some of SOT package and found out that no one excess 1.10mm . This maximum height, specified for SOT, is maybe something related to old…

Dual transils in SOT-23

It would be probably good to protect N-MOSFET with its drain connected to a long (~1 m) piece of wire against ESD. The transistor has its drain-source maximum voltage 20 V, so I decided to choose MMBZ16VALFHT116 (datasheet) transient voltage…

Help identifying a failed SOT23 component via markings “Nos”

This part may be damaged (outwardly it’s intact). It comes from a proprietary video card from 18+ years ago I’m trying to fix (finding another card has been a challenge). This component currently only has a diode connection between one of the leg…
