Thank you very much. So the leftmost pin is the emitter, the middle is the collector, and the rightmost pin is the base? Be the first to write a review. This item doesn’t belong on this page.

This is the price excluding shipping and handling fees a seller has provided at which the same item, or one that is nearly identical to it, is being offered for sale or has been offered for sale in the recent past. At Dalbani we like to differentiate between new, previously installed parts usedand parts made by 3rd party manufacturers. Are you sure that a it is an NPN transistior b with a sufficient B current amplification factor and c that you connected it correctly?

I’ve been working with an Arduino lately, and building various breadboard circuits.

I understand that a “real” CMOS inverter is a better choice for this application, but bear with me. Might be a silly question but did you check the pinout of the switching device? Golden rule – always read the data sheet and if you can’t find one then don’t assume. V1740 thought switching transistors were tuned for very “snappy” response that tends to be either fully on or fully off.

DuncanC I would say that in the diagram where I drew the red box the flat side is facing the reader. How to invert a digital signal The circuit looks like this: Also, I would use a much lower resistor instead of k, maybe 10k.

Is the flat side facing up in the red box above? Let us fix the problem for you.

I could do it with a quad NOR gate, but that is a 14 pin DIP package that needs 12 wires connected when you include tying unused inputs to ground. Saturated means fully on; and 10 more or less 20 is usually OK and saves base current.

The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. The price may be the seller’s own price elsewhere f1740 another seller’s price. I’m having a little trouble understanding the pinout diagram from that data sheet.

Skip to main content. These are loose parts that I’ve collected in various electronics kits and projects through the years. I could not find datasheet for the C Transustor C 1 10 Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

A simple example was to build a transistor based inverter for a project involving baud serial combination at 5v. It’s maddening that the pinouts aren’t the same. The base and collector are reversed from the 2nA?

Andy aka d1740 10 What is it about transkstor transistors that makes them unsuitable for a circuit like this? I just swapped the base and collector in my breadboard, and now the C works in place of the A.

Post as a guest Name. That takes a lot of room on my breadboard and a lot of time to set up.

I don’t know for sure what these are. So is that a rule of thumb, make r2 10x the r1 value? If the pins are not in standard order that would certainly explain it though! Hey try it both ways or even test it with a multimeter for diode between base and collector and base and emitter. Exactly 10x, or 10 or less? The “off” amount and percentage simply signifies the calculated difference between the seller-provided price for the item elsewhere and the seller’s price on eBay.
