Frequently Asked Questions
Which maker built this 2N351A?
ITT. The block-letter ITT logo is printed on the cap directly under the part number.
What polarity is the 2N351A?
PNP. A TO-3 can looks the same whichever polarity sits inside, so the number on the cap is what tells it apart from other transistors in the same outline.
The three letters on the cap stand for International Telephone and Telegraph, a long way from the telegraph key to a PNP power can. The empty pair of holes on an old heatsink is where it goes to work.
