Unknown "transistor" in TO92-package

Oct 31, 2005 5 Replies

Greetings



I pillaged a dead TV for components yesterday. I found a "transistor", TO92-package, with no middle leg. That is, it looks like an ordinary bipolar transistor, but the middle leg is gone. Its printing is "N38 (new row) T" and nothing else. Google gave me no hope.



Anyone know what this component is?

Might be a varactor diode. Or some other kind of two-leaded semiconductor device. ;-)

It's an ICP - Integrated Circuit Protector. Semiconductor fuse, in other words.

The N indicates (I think) anti-surge, and 38 is the rating devided by

40, so this is a 1.5 Amp.

"ICP-N38" is the device to ask for.

Probably a diode. Not 100 prc sure about it. Don't you have a diode tester to test it?

Varicaps AKA varactors or variable capacitance diodes commonly come in this package. It could also be a regular or zener diode, or even an IR sensor. With a TV, I would suspect a varicap. You should check out the circuit that it came from for more hints.

"transistor",

Excellent info, Laurence. I've seen these protectors come in blockish shaped transistor sized cases, but never in TO-92. Good to know the formula for the current, also. Thanks.
