What role would Q2 play in that configuration?

Test your settings by visiting www. I kind of suspect a diode, but can’t figure out why a plain dztasheet diode wouldn’t work better and be a lot cheaper.

2N4033 Datasheet

Mouser Electronics har 2nn4033 TLS 1. While a diode could technically accomplish the same function, using a matched transistor should give a more similar response.

Putting the plain diode on the heat sink with the transistor might be an improvement. How it dattasheet that way is the question A quick google shows a different layout for the same though, 2. Some suggested transistors are listed below.

satasheet I renamed the transistors to reflect Op’s circuit, to avoid confusion. Finally forced air cooling 2n datasheet a fan could be used in the design or attaching a heat sink to the 2n datasheet can of the 2N would greatly reduce the amount of 2n datasheet required.

2N4033 PNP General Purpose Transistor (Pack of 5)

The numbering comes from the short circuit protection being an add on to the original external pass transistor circuit, instead from scratch.

This short circuit protection is added because of the use of an external pass transistor prevents the internal short circuit protection from working.

I can’t say I’ve ever seen that before and search didn’t turn up anything. Sign up using Facebook. Number things left-to-right and top-to-bottom. The chart details the maximum allowable power dissipation with 2n datasheet ambient temperature for a 2N transistor. Funny, everyone else has the second layout, fairchild, st, onsemi. C-E current to satisfy gain. Dave2n datasheet 30, Yes, my password is: Would that be likely to have the same voltage drop but allow more current or something?

This is the current setup two more pairs like this for the other cylinders that 2n datasheet producing weak spark: But the accuracy of the scaling is controlled by the V BE match.

On this topic, ignore the Wikipedia article. The minimum input-to-output voltage differential of the regulator circuit is increased by a diode drop plus the Vr1 drop.


Their LM data sheet has the second layout. It reduces Q1’s share of the load current when load 2n403 is small. You will see schematics of variations using two BJTs: I think they goofed. They did have it top to bottom numbering though.

It could just be omitted, if short circuit protection is not needed.

What would be the rationale for using the C-B junction as well as the E-B junction? Who knew you could build a switching converter with an LM? If you disconnect their collector from emitter and connect it to base, you get a current mirror or current multiplier.

But not many give practical applications like this power booster. Left drives and right receives. R3 is more subtle. In this configuration they almost have the same IV curve, but the NPN doesn’t work the same as a diode when in the negative sweep like two back to back diodes would. If the LM78L05 stops sinking current, Q1 will turn off. Note how 2n40333 has its collector and emitter shorted.
