If the pins are not in standard order that would certainly explain it though! The base and collector are reversed from the 2nA? How to invert a digital signal. These are loose parts that I’ve collected in various electronics kits and projects through the years.

Show More Show Less. What is it about switching transistors that makes them unsuitable for a circuit like this?

This item doesn’t belong on this page. So is that a rule of thumb, make r2 10x the r1 value? How to invert a digital signal The circuit looks like this: I could not find datasheet for the C 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.

Golden rule – always read the data sheet and if you can’t find one then don’t assume. Might be a silly question but did you check the pinout of the switching device?

Thank you very much. Home Questions Tags Users Unanswered.

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? Post as a guest Name. I don’t know for sure what these are. Sign up using Facebook. Also, I would use a much lower resistor instead of k, maybe 10k.

Email Required, but never shown. See details for additional description. A simple example was to build a transistor based inverter for a project involving baud serial combination at 5v. That takes a lot of room on my breadboard and a lot of time to set up. Let us fix the problem for you. I thought switching transistors were tuned for very “snappy” response that tends to be either fully on or fully off. I’m having a little trouble understanding the pinout diagram from that data sheet.

We have ratings, but no written reviews for this, yet. Best Selling in Transistors See all. At Dalbani we like to differentiate between new, previously installed parts usedand parts made by 3rd party manufacturers.

It’s maddening that the pinouts aren’t the same. You may also like. Duncan C 1 10 The price may be the seller’s own price elsewhere or another seller’s price.

Transkstor built an inverter based on this thread: I just swapped the base and collector in my breadboard, and now the C works in place of the A.

Is the flat side facing up in the red box above? DuncanC I would say that in the transisor where I drew the red box the flat side is c140 the reader. Be the first to write a review. 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. Skip to main content. So the leftmost pin is the emitter, the middle is the collector, and the rightmost pin is the base?

Why won’t a switching transistor work in this transkstor Ask Question. Exactly 10x, or transitor or less? I’ve been working with an Arduino lately, and building various breadboard circuits.
