Product Details

2N2219 NPN Transistor - Higher Current Switching in a Metal-Can Package

The 2N2219 is an NPN silicon transistor housed in a hermetic TO-39 metal can, valued for its ability to handle higher collector currents and dissipate more heat than standard TO-92 parts. It shares the same core electrical family as the popular 2N2222 but in a sturdier package suited to slightly more demanding switching and amplification circuits.

Functions & Applications

Higher Current Handling: Rated for up to 800mA collector current, more than typical small-signal TO-92 transistors.
Rugged TO-39 Metal Case: Hermetically sealed package offers better heat dissipation and mechanical durability.
Fast Switching: Transition frequency around 250MHz suits high-speed switching designs.
Proven Legacy Part: Widely documented, easy to find equivalents and complementary parts for repair or vintage circuit work.

Frequently Asked Questions

Q: What is the complementary PNP part for the 2N2219?
A: The typical complementary PNP transistor is the 2N2905, matched for similar voltage and current ratings in the same TO-39 style package.

Q: How much current can the 2N2219 switch?
A: It can handle up to 800mA of continuous collector current, making it suitable for driving small relays, higher-current LEDs or medium-power loads directly.

Notes

This is a legacy/classic part in a hermetic metal-can TO-39 package rather than modern plastic packaging - keep this in mind when designing PCB footprints.

Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
