Description
The MMBT2222 is a high-speed NPN switching transistor, widely regarded as a fundamental component for professional electronic designs. Featuring a robust 600 mA collector current capacity and a reliable gain (hFE) of 100 to 300, it is perfectly suited for general-purpose switching and medium-speed amplification tasks where performance and footprint are critical.
Housed in a compact, surface-mount (SMD) package, the MMBT2222 is optimized for modern high-density PCB layouts. Its ability to handle up to 40V (Vce) and its wide operating temperature range of -55°C to +150°C make it an incredibly versatile choice for everything from portable consumer electronics to industrial control interfaces. This pack of 15 units provides a high-value, reliable solution for your ongoing production, maintenance, or R&D requirements.
