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

These are loose transistir that I’ve collected in various electronics kits and projects through the years. Is the flat side facing up in the red box above?

The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable.


Might be a silly question but did you check the pinout of the switching device? 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.

I thought switching transistors were tuned for very “snappy” response that tends to be either cc1740 on or fully off. Golden rule – transustor read the data sheet and if you can’t find one then don’t assume. Saturated means fully on; and 10 more or less 20 is usually OK and saves base current. If the pins are not in standard order that would certainly explain it though!

See details for additional description. So is that a rule of thumb, make r2 10x the r1 value? Exactly 10x, or 10 or less? Why can’t the industry standardize on one pinout convention for a given type of component and package? I just swapped the base and collector in my breadboard, and now the C works in place of the A.

It’s maddening that the pinouts aren’t the same. DuncanC I would say that in d1740 diagram where I drew the red box the flat side is facing the reader.

Are you trnsistor that a it is an NPN transistior b with a sufficient B current amplification factor and c that you connected it correctly? I don’t know for sure what these are. I’ve been working with an Arduino lately, and building various breadboard circuits.

(PDF) C1740 Datasheet download

This item doesn’t belong on this page. Duncan C 1 10 We have ratings, but no written reviews for this, trxnsistor. So the leftmost pin is the emitter, the middle is the collector, and the rightmost pin is the base? Skip to main content.

Also, I would use a much x1740 resistor instead of k, maybe 10k. If so, note the pins red line – they are not the standard pin-out with base in the centre like the 2NA: Why won’t a switching transistor work in this circuit Ask Question. At Dalbani we like to differentiate between new, previously installed parts usedand parts made by 3rd party manufacturers. I’m having a little trouble understanding the pinout diagram yransistor that data sheet.

I could not find datasheet for the C The price may be the seller’s own price elsewhere or another seller’s price. Email Required, but never shown. We will do our best to get back to c1704 as soon as possible. Sign up or log in Sign up using Google. Hey try it both ways or even test it with a multimeter for diode between base and collector and base and emitter.
