n2222mL2

n2222mL2 is a designation that appears to refer to a variant within the widely used 2N2222 family of NPN general-purpose transistors. The lowercase prefix and the suffix ML2 are not standardized across public catalogs and may indicate a manufacturer-specific packaging, lot code, or internal designation. Because there is no universally recognized datasheet under the exact name n2222mL2, exact electrical parameters and physical form factor can vary by supplier.

The 2N2222 transistor family comprises small-signal NPN devices intended for general switching and amplification in low-power circuits. They are commonly employed to drive relays, act as amplifiers in hobby and educational projects, and serve as basic switching transistors in low-current applications. Variants differ in packaging, gain, voltage rating, and current capability, so applications are chosen based on the specific vendor’s datasheet.

Packaging and form factor for 2N2222 devices typically include through-hole TO-92 and other compact packages, with surface-mount options in some families. If n2222mL2 denotes a particular ML2 packaging variant issued by a manufacturer, the exact package, pinout, and mounting requirements should be confirmed from that supplier’s datasheet. Without that documentation, assumptions about pin arrangement and thermal characteristics should be avoided.

Electrical characteristics for the 2N2222 family generally include a collector-emitter voltage rating in the tens of volts, a maximum collector current of several hundred milliamps, and a relatively wide current gain (hFE) that varies with operating conditions. Because specific values depend on the exact variant and production lot, consult the precise manufacturer datasheet for n2222mL2 to determine appropriate operating limits, safe operating area, and recommended drive conditions.
