KST2222AMTF Offers Compact, High-Speed NPN Performance

Small signal circuits often need a transistor that can handle more than basic switching. The KST2222AMTF provides a practical NPN solution for compatible designs, with a 40 V collector-emitter rating and 600 mA maximum collector current. Its SOT-23-3 surface-mount package also fits compact PCB layouts and supports straightforward automated assembly.

With a 350 mW maximum power rating and 300 MHz transition frequency, the KST2222AMTF can serve in general-purpose switching and amplification stages. It offers a minimum DC current gain of 100 at 150 mA and 10 V, while its single-transistor configuration keeps circuit integration simple. The device also has a 6 V emitter-base breakdown rating, providing useful electrical characteristics for suitable low-power designs.

The KST2222AMTF is an obsolete onsemi part, making accurate sourcing important for legacy equipment and replacement work. Need this exact component? Contact Florida Circuit today for pricing, availability, and sourcing assistance.
