I suspect that the price reflects the cost of keeping them in stock for people like me that need 3 of 'em, but are 200 miles from the nearest Radio Shack. Yeah, I could order from Jameco, Mouser, or DigiKey, but it's not like I can send them a quarter and an SASE and get 3 transistors and a penny by return mail.</p>

Can there be different voltages between B and C/E? Meaning - can I use 3v on B to enable 5v thru C to E?</p></p>
