Product Overview
Sealed Motorola 2N3441 NPN Power Transistor in a Gold TO-3 Can, Date Code 7326
Condition
Unused, new old stock in the original manufacturer's packaging. The photograph shows one transistor still sealed inside a clear blister on a printed Motorola card. Through the blister the metal can reads with the Motorola batwing logo, 2N3441, and the date code 7326. The TO-3 flange is gold plated with the usual mottled tone of long-stored plating, and the digits 46 are stamped into the flange next to one mounting hole. The blister is intact and has not been opened, so the pins are not visible in the photograph. The card shows light storage scuffing at the edges.

Product Overview
The 2N3441 is a silicon NPN power transistor in the classic TO-3 metal case, a JEDEC registered number that was second sourced across the industry and shows up in linear power supplies, audio output stages, series pass regulators, and motor drive circuits from the 1970s and 1980s. This one is Motorola's own part, still sealed in Motorola blister packaging, with the can marked 2N3441 and the date code 7326 that places the batch in 1973. The TO-3 package mounts flat to a heat sink or chassis through the two flange holes, with the case itself serving as the collector connection. Electrical ratings are not confirmed here - work from a 2N3441 datasheet before designing it into a circuit.

Applications
- Audio restorer rebuilding a 1970s solid state amplifier output stage that calls out the original TO-3 device

- Industrial maintenance tech keeping a legacy motor drive or control cabinet running on its original semiconductor line-up
- Collector or archivist wanting a Motorola dated part still sealed in period blister packaging
Frequently Asked Questions
What exactly do the markings on the can say?
Read through the blister, the can carries the Motorola batwing logo, the part number 2N3441, and the four digit code 7326 below it. A separate 46 is stamped into the gold flange next to one of the mounting holes. Those are the only markings legible in the photograph.
Does 7326 mean anything useful?
It is the factory date code, read as year and week, which puts this batch in 1973. It tells you the part is genuine period Motorola production rather than a recent remark, and it is worth noting if you are matching devices to an original build.
Will the packaging be opened before shipping?
No. The blister is sealed and it ships that way. That also means the pins and the underside of the can have not been photographed or inspected outside the packaging, and no electrical testing has been performed.
What voltage and current can it handle?
Not confirmed here. The 2N3441 is a registered JEDEC number, so pull a 2N3441 datasheet and design to the published limits rather than to anything assumed from the package size.
Why buy this one sealed, dated piece instead of chasing a surplus lot?
Stock here is two. What you get is this exact device, photographed in its sealed Motorola blister with the part number and the 7326 date code readable in the picture, rather than a bag of loose TO-3 cans from an auction pallet where half the markings are sanded, remarked, or simply gone. For one repair or one matched pair you are buying a known piece instead of sorting through unknowns. Shipping is $8 flat rate, free once the order passes $28, and orders leave our Idaho warehouse the same or next business day.
Nineteen seventy-three sealed under plastic, gold flange still bright, waiting out fifty years for a chassis that needs it. Break the blister and the wait is over - that amplifier or supply gets its original heart back.
