Hi, does this make much sense? http://smartheatsinks.com/SHS_SMT.pdf The heat path between the transistor and the heatsink is awkward. Best regards, Piotr

All you electronics|semiconductor gurus here. Any commercially available junctionless transistors ? Kist curious .

Hi For fun I need to inspect the die in a typical BC847 SOT23 plastic housing How do one decap that transistor? Cheers Klaus

Gentlemen, I'm trying to find a datasheet for the BLX67 transistor but so far without any luck. Various sites on the web claim to have one, but when I looked closer they were all BLX65 devices and nothing for the 67. Any suggestions as to where I might strike lucky? CD.

Imagine an NPN transistor. Ground the emitter and connect the collector to some nice positive voltage. Now pull the base negative, through a current-limiting resistor. What happens?

Gentlemen, I've come across an RF transistor which seems to be available in 3 very different ecapsulations. I'll use these links from Ebay for simplicity and hope they're still up by the time anyone reads this. :-) The first case appears to be based on the TO-220 dimensionos but appears to be all plastic: https://tinyurl.com/yfnfchtk The second is what I would typically expect to ...

Has anyone seen a NPN bipolar transistor with emitter in the middle, tab. Emitter is easier to ground in RF amplifiers.

Could some electronics guri here help please ? Where could I find datasheets, specifications and SPICE models if any, of commercially available hetero bijunction transistors. Thanks in advance.

Hi all, It still amazes me after all the years LTspice has been around the standard parts library in it remains so tiny. I don't think this long- standing defect in otherwise very good program will ever be fixed. So like anyway, has anyone got a model for a BD131 NPN transistor they could post here? TIA folks. CD

I remember reading some while ago that LLL was working with fast switching = transistors which generated "radar wavelength" signals. Then, as events go,= a Georgia Tech Prof. raised a stink since he had previously developed thos= e applications. Again, a vague memory. Does anyone recall this? TIA JB

I'm trying to add the models of a couple of N-FETs I use to LTSpice. I'm getting a simulation-time error that I can't resolve. Any ideas? Thanks. The error: |M1: Only a level 9 B3SOI can have 6 nodes It thinks I have six terminals on my transistor and only SOI models have that many? Looks like only three to me. The circuit: Version 4 SHEET 1 880 680 WIRE 144 -80 16 -80 ...

I decided to delve deeper into the mystery. Here is an .asc file of the strange circuit previously under discussion. https://app.box.com/s/cwlnjt5zh14ubdaul4odvhcehw2tnapa Unless I have made an error, it appears to be non-functional. I am now preparing a bonfire for my collection of such old documents. Robert Miller

Hello, I know that there are hordes of nice comparators in SOT-23, but just out of curiosity: is it possible to build a small voltage (relatively to GND) detector using just one transistor and no negative power supplies? If the voltage is > = VBE, i.e. 0.7V, then the task is a no-brainer, but how about half of that, say, 0.3V? Best reagrds, Piotr

I'm using a TIP31C (pnp in to-220 pac) as a temp sensor (diode connected) There's a couple of depletion fets in series as current limiters. (LND150) The b-e junction starts to zener at ~30 V (only two tested so far). So I've got ~1.5 mA flowing at 30 V. Is this going to damage the junction? Will it take time? I'm going to measure forward voltage again after zenering for 15 minutes. Sho...
