Product Overview
A silicon PNP power transistor from Motorola, the 2N3741 is rated 80 V collector-emitter and 4 A collector current, with 25 W dissipation at a 25 C case. It sits in the TO-66 metal can, the smaller two-hole diamond-flange cousin of TO-3.
Key Features
- Polarity: PNP, silicon
- VCBO 80 V, VCEO 80 V, VEBO 7.0 V
- Collector current (IC): 4.0 A
- Power dissipation: 25 W at TC 25 C
- DC current gain (hFE): 10 minimum at IC 1.0 A
- Transition frequency (fT): 4.0 MHz
- Package: TO-66 metal can, diamond flange with two mounting holes
Applications
- Replacing a PNP 2N3741 in a vintage linear power supply or audio output stage built around TO-66 cans
- Building a PNP pass or driver stage into a bench-built linear supply or amplifier
Frequently Asked Questions
Is this a TO-3 transistor?
No. The 2N3741 is a TO-66 part. TO-66 is smaller than TO-3 and its mounting holes sit closer together, so TO-3 heat-sink drilling and TO-3 insulators do not line up.
Is the 2N3741 NPN or PNP?
PNP.
How is the 2N3741 different from the 2N3740?
The 2N3741 is the 80 V grade, rated 80 V collector to emitter; the 2N3740 is the 60 V grade.
From the era when power meant a metal can bolted through a diamond flange. If an old amplifier or supply lost its 2N3741, this is the Motorola number its heat sink was drilled for.
